LG 27GX790A

88 / 100 Excellent

Based on 26 sources How we score

Best For

  • Esports players seeking razor-sharp motion
  • Gamers valuing color accuracy and vibrant visuals
  • Enthusiasts who prefer a sleek, clutter-free design

Consider Carefully

  • Users needing built-in speakers for multimedia
  • Professionals requiring sharp text for productivity tasks

The Bottom Line

The LG 27GX790A stands out as a high-performance gaming monitor that delivers on its promise of exceptional visual quality and smooth gameplay. What we found particularly impressive is its class-leading 480Hz motion clarity and over 96% DCI-P3 color coverage, which earned it high praise from nearly every expert source. With G-Sync and FreeSync Premium Pro certification, it's clear this monitor is built for the most demanding esports players and enthusiasts. Its sleek, virtually borderless design is also a standout feature, enhancing the immersive experience. However, the lack of internal speakers and subpar text clarity for productivity tasks are notable downsides, as is the premium price point and the grainy 'dirty screen effect' some owners report from the matte coating.

Performance Breakdown

In-Depth Analysis

Refresh Rate Performance 95

Unanimous consensus ยท 17 sources

480Hz at 1440p is the fastest OLED refresh rate you can buy right now, and 17 sources essentially agree on that. The catch: you need a GPU powerful enough to actually feed it.

Key Takeaway

โ†’If you play fast-paced esports titles and have a top-tier GPU, this is the sharpest, fastest 1440p OLED available. If your rig can't sustain 400+ fps, you're buying headroom you can't use yet.

Refresh Rate Performance

Unanimous consensus ยท 17 sources
95 / 100

Eight sources, including RTINGS and PCWorld, call the motion clarity exceptional, and the 0.03ms OLED response time is in a different category from any LCD. PCGamer confirms it sits at the top of the 1440p OLED refresh rate stack. But three sources, including PCMag and Khen Tech Reviews, flag that reaching 480fps requires cutting-edge hardware most people don't own yet. Reddit's r/OLED_Gaming adds a practical wrinkle: VRR flicker is real and noticeable. One reviewer noted that 240Hz users upgrading here will feel improvement, but not a revelation. If you're already pushing high frames in esports titles, this is the monitor. If you're not, the panel is future-proofing you're paying for today.

Best for competitive gamers who play lighter titles capable of 400+ FPS and want future-proofing

โ€” r/OLED_Gaming

Where Reviewers Disagree

The 480Hz ceiling is real, but reaching it requires hardware most setups don't have, and VRR flicker undercuts the experience when frame rates drop.

Gaming Performance

90 / 100

Tom's Hardware measured record-low input lag with perfect motion resolution, and PCGamer's 0.03ms response time figure puts it in a class LCD panels simply can't reach. The dual VRR certification, covering both AMD and Nvidia ecosystems, removes a common compatibility headache. At $999, it undercuts some key rivals, which trustedreviews.com and GamesRadar both noted. The weaknesses are specific: no dual resolution mode unlike some competitors, no sniper mode or timer overlays, and VRR flicker is a documented issue from XDA-Developers. Firmware also needed an update to fix 60Hz input lag at launch, per RTINGS. For cinematic open-world gaming, two sources including MDee14 say the OLED color depth holds up well. But the consensus across 13 sources is clear: this monitor was designed for one type of gamer.

89 / 100

TrustedReviews and GamesRadar both highlight the flat, thin base as a practical desk space win, and the full adjustment range covering height, tilt, swivel, and portrait pivot earns consistent praise across three sources. GamingTrend specifically calls out the cable management slot as a thoughtful detail. The stand is heavy and stable, which matters for a monitor you're adjusting frequently. The one dissent worth noting: GamingTrend found the slim profile made mounting feel slightly precarious during setup, and Khen Tech Reviews recommends replacing the stock stand with a monitor arm entirely. VESA 100x100mm compatibility makes that straightforward. For most users, the stock stand is genuinely good. For power users who want maximum flexibility, the arm upgrade path is clean.

Color Accuracy 86

Strong consensus ยท 11 sources

98.5% DCI-P3 coverage is strong across four sources, but the WOLED panel trails QD-OLED alternatives in color volume, and out-of-box calibration is a known weak point.

Key Takeaway

Color Accuracy

Strong consensus ยท 11 sources
86 / 100

Tom's Hardware and GamingTrend both confirm the wide color gamut, with coverage landing above 96% DCI-P3 across multiple measurements. For gaming, the W-OLED color representation earns genuine praise from XDA-Developers. The problem is the baseline. Tom's Hardware flags that calibration is required for best accuracy, and r/OLED_Gaming is direct: factory calibration is inadequate, and you should budget for a calibration device or accept suboptimal colors. PCWorld notes the color gamut is modest compared to QD-OLED alternatives, which is a real gap if color volume matters to you. GAMETIME suggests the accuracy is sufficient for professional creative work, but that sits in tension with the calibration warnings from two other sources. For gaming, it's excellent. For anything requiring accurate color out of the box, plan to calibrate.

Display Image Quality

Strong consensus ยท 23 sources
77 / 100

The contrast and black levels draw consistent praise across sources including T3, PCWorld, and GamingTrend. For gaming, the WOLED panel delivers. But the image quality story gets complicated fast. PCGamer notes this is last-generation WOLED without a Quantum Dot layer, meaning color volume and peak brightness trail newer panels. Five sources flag that 1440p looks noticeably softer than 4K alternatives for text and productivity work. XDA-Developers specifically calls out subpar text clarity for desktop use. R/OLED_Gaming goes further, warning that the matte coating permanently compromises OLED's inherent clarity advantages and that graininess in grays is a fixed characteristic of this panel. This is a gaming display first, and treating it as anything else will disappoint.

PCWorld and TrustedReviews both praise the charcoal finish and thin bezels, and Tom's Hardware calls the stand and build quality premium outright. RTINGS notes the firmware is more stable with fewer bugs than competitors, which matters more than it sounds. But the omissions stack up. Nine sources, a near-unanimous count, flag no built-in speakers. PCGamer and GamesRadar both note the feature set is slimmer than other UltraGear monitors at this price. RGB lighting, while present, is dim with limited customization according to PCWorld and GamingTrend. The joystick OSD control draws a specific complaint from GamesRadar. At $999, you're paying for the panel and the build, not a feature-rich package.

PCGamer confirms both DisplayPort 2.1a and HDMI 2.1 carry the full 480Hz signal, which is not a given at this refresh rate. Four sources call the DisplayPort 2.1 support future-proof for upcoming GPU generations. The USB hub, outward-facing IO, and four-pole headset jack with DTS:X are practical additions GamingTrend and PCMag both appreciated. But five sources, including PCWorld and PCGamer, flag the USB-C omission as a real limitation for anyone who uses a laptop alongside their desktop. PCMag calls the overall port selection light. The sharpest warning comes from r/OLED_Gaming, which notes that DisplayPort 2.1 with the latest Nvidia GPUs requires significant technical troubleshooting, not a plug-and-play experience.

HDR & Brightness

Strong consensus ยท 12 sources
71 / 100

Tom's Hardware called the HDR image stunning and noted it outperforms some competitors in peak HDR brightness. The DisplayHDR True Black 400 certification is legitimate, and MLA+ does add measurable brightness over standard WOLED. But the full-screen SDR number tells a different story. PCMag measured only 234 nits average, below even the 250-nit spec. PCGamer puts typical full-screen brightness at 275 nits and notes newer RGB Tandem OLED panels beat it. Five sources, including T3 and GamesRadar, flag that bright rooms are a real problem. R/OLED_Gaming is blunter, calling HDR performance particularly disappointing and noting SDR requires Windows color management intervention to look right. Six sources converge on the same recommendation: controlled lighting is not optional here, it's a requirement.

It's not the most budget-friendly option, but its performance justifies the price for those who want the best. If you're not an avid gamer or need a monitor for detailed work, there may be more cost-effective alternatives.

Staple Monitor for what is to come in the Monitor Market

Falinks โ€ข 2026-06-13
This is the best looking monitor I have ever owned. The colors are amazing and the 480fps is so cool to look at. My mouse pointer has never been seen so smooth. Hopefully it will last me some years to come.

Great screen, especially valuable on sale!

tyler โ€ข 2026-06-24
I love this screen. It has a screen cleaning process that runs when your screen is inactive to help make sure you don’t get any bad pixels or burn in. I am on it quite a bit for gaming and it is beautiful. The 480hz is amazing too. If you can find this on sale it is even better value. Great purchase for me.

Perfect for my needs, some questionable reviews

Robert โ€ข 2025-03-29
There are some questionable reviews on this monitor. Iโ€™ve been using this monitor since early February. The only downside is even though itโ€™s listed at dp 2.1 but it isnโ€™t the full speed, requiring you to run it with DSC, which honestly hasnโ€™t been an issue for me so far. People are saying the brightness is too low and I disagree completely. Iโ€™m willing to bet they didnโ€™t know about the peak brightness increase in the settings. This panel gets extremely bright and rivals the brightness of my lg c1 OLED at high peak brightness in hdr. Also someone mentioned a lack of panel care settings and I also disagree, as there are 4 different pixel shifting modes to choose from, panel cleaning when in sleep, and dimming when displaying static content for long periods of time. Someone also mentioned not being able to tell if the monitor was asleep due to no front light, but there is an led ambient light on the back is you choose to enable it that serves the exact purpose theyโ€™re complaining about.If you can catch this monitor for $100+ off, itโ€™s an insanely good panel. Impeccable response times, 480hz, bright hdr, amazing black levels, great build quality and stand, thereโ€™s not much more I could ask for in a display. Iโ€™ve been enjoying games old and new on this panel at extremely high frame rates and I can never go back. 480hz feels like looking through a window, the motion clarity is something you have to see in person

OPENED BOX SOLD NEW. LG DEALERSHIP NIGHTMARE. 30 DAY RETURN PROCESS.

Eman โ€ข 2025-08-06
By far the worst experience ever ordering a display from Amazon. WARNING! This doesnโ€™t come from LG directly. Instead, an LG certified dealer will ship your expensive display in a refurbished box thatโ€™s opened. Good luck returning the item. There is a reason why this product is marked as frequently returned. I purchased this a month ago and still waiting for my refund. Amazon is experiencing significant delays in processing returns so be ready to wait 30 days for your return to process. I regret this purchase more than anything! I wouldโ€™ve avoided all of this had I read the reviewers. I trusted LG and didnโ€™t feel the need to investigate the product. Donโ€™t fail like I! Please do your research and stop ordering from Amazon. Otherwise, they will continue to take us customers for granted. Imagine if we all stopped ordering this product? Amazon would have no choice but to act and make it right to us customers. They can care less for the customers experience as long as the money keeps flowing.

Great monitor.

abe โ€ข 2026-06-12
Great monitor. Amazing picture. This was my first OLED. Thereโ€™s no going back once youโ€™ve experienced a nice OLED. With 480hz, youโ€™re good to go for a while. Future proof for next generation.

Mixed emotions but still a good product.

Thomas M. โ€ข 2025-12-25
This monitor is gorgeous. Its a very amazing OLED with good response time and a great refreshrate however i have a 4090 and mainly play cs2 and it just doesnt feel like I really got that much more of a boost coming from 240hz. I didnt expect a night and day difference and it could be the game (cs2 is buns with the sub tick system) even on my desktop I still can see my mouse having like a trail (not ghosting) where it just seems like a lower refresh maybe ive gotten to used to super high ones but idk. Overall I would recommend this monitor if its on sale, yoy are upgrading from below 240hz and you want an oled. If you have the 240hz OLED model id probably keep it or find another brand with a higher refreshrate.

Quality OLED Panel

Adrian โ€ข 2026-06-14
Amazing OLED panel for a fraction of the cost. I use this mainly for entertainment, work, and a little bit of gaming. Colors are rich and the blacks are actually black!

Good but could be better

Zane D โ€ข 2025-03-17
This is a good monitor with tons of potentials. I enjoy the oled and high refresh rates. Color looks decent and definitely clean. However I returned it for two reasons: 1. The display port doesnโ€™t work with anything if you are running non native resolutions. Like I tried with CS2 and Marvel Rivals and had tons of issues. You can look it up annd others have the same issues. Only way to get it working is to use the hdmi 2.1 cord. I feel like a monitor cost over $1000 should have these things worked out.2. Itโ€™s just too expensive and not perfect so I returned it. But I still bought another one from other places which were in sale for much less price.In the end itโ€™s a good monitor that does what I wanted, wish the display port would work better though.

Reader Questions

Specific questions about the LG 27GX790A, answered only from what reviewers reported.

01Is 480Hz actually worth it for competitive gaming?

Reviewers consistently found the 480Hz refresh rate delivers class-leading motion clarity, with real-world input lag staying under 4 milliseconds. It is noted as the fastest refresh rate available on a 1440p OLED, giving competitive players meaningful headroom in high-FPS titles.

3 sources “Class-leading 480Hz motion clarity” — pcworld.com

02How good is the picture quality for games and HDR content?

The W-OLED panel covers up to 98.5% of the DCI-P3 color space with deep blacks and vibrant colors. HDR performance is strong, backed by wide DCI-P3 and Rec. 2020 coverage, though full-screen brightness sits at around 275 nits in typical use.

3 sources “98.5% DCI-P3 coverage with Delta E below 2” — GAMETIME

03Is this monitor good for productivity and everyday desktop use?

Text clarity is a noted weakness, with reviewers describing rendering as blurry out of the box and failing to match LCD standards. The matte coating can also create a hazy or grainy appearance that some users find problematic for browsing and productivity work.

3 sources “Text clarity is subpar for desktop and productivity use” — xda-developers.com

04Does it work with both Nvidia and AMD graphics cards?

The monitor carries both G-Sync and FreeSync Premium Pro certification, so it supports adaptive sync on either platform. The full 480Hz refresh rate is accessible over both DisplayPort 2.1 and HDMI 2.1 connections.

3 sources “G-Sync and FreeSync Premium Pro certified” — tomshardware.com

05Does the matte coating handle glare well in bright rooms?

Multiple reviewers confirmed the matte finish effectively reduces glare and reflections from windows and daylight sources. However, some users found the same coating creates a grainy or dirty visual effect, so sensitivity to that trade-off varies.

3 sources “Matte finish effectively reduces glare and reflections from windows and daylight sources, confirmed by multiple users” — r/OLED_Gaming

06Does it have built-in speakers?

No, the LG 27GX790A does not include internal speakers. You will need external speakers or headphones for audio.

Testing this 480Hz OLED monitor revealed impressive clarity and smoothness, though achieving the full 480Hz requires significant compromises in most games. The matte screen delivers exceptional clarity that rivals glossy alternatives, with peak brightness reaching 603 nits in HDR. In Fortnite, performance mode was needed to approach high frame rates but looked unacceptable. Call of Duty similarly required lowered settings the reviewer refused to use. The monitor truly shines in esports titles like Valorant where it runs smoothly without graphical sacrifices. The reviewer notes 480Hz offers marginal improvement over 240Hzโ€”slightly faster image clarity during motionโ€”but considers it transformative specifically for competitive gaming rather than general use.

  • โ†’Ideal for Valorant, CSGO, Apex Legends competitive players
  • โ†’Avoid if Call of Duty or Fortnite are primary games

Purchased for approximately $610, this 27-inch 1440p OLED monitor delivers exceptional speed with its 480Hz refresh rate and 0.03ms response time, making it ideal for competitive esports titles. The reviewer praises its bright MLA+ panel, excellent out-of-box colors, and clean image quality without artifacts or ghosting. However, the 24-inch mode suffers from blurry pixel mapping issues, the silver reflective design and monitor legs are unappealing, and the warranty period feels short at just one year for burn-in. Adaptive sync can cause flickering in dark scenarios. Driving 480FPS requires top-tier hardware including a 9800X3D or better CPU and 5070 Ti or greater GPU, limiting the monitor's practical use to a handful of games.

The LG 27GX790A is a high-refresh rate OLED monitor positioned as a more affordable alternative to 500Hz competitors, priced similarly to 280Hz tandem OLED options. However, early adopters report significant quality control issues. Multiple owners describe severe near-black performance problems including black crush and banding that cannot be fixed through settings. Grey uniformity issues improve slightly after pixel refreshes but remain unacceptable for the price point. Users also report VRR flicker, gamma shift, and color inconsistency artifacts. At least two owners initiated returns after brief testing, with one user planning to stay on LCD until OLED panel flaws are resolved.

Key Insights

  • โ†’Best suited for users prioritizing refresh rate and price over near-black shadow detail accuracy
  • โ†’Not ideal for dark room gaming or content with heavy shadow detail due to unfixable black crush
  • โ†’Quality control appears inconsistent enough that multiple early adopters initiated returns
  • โ†’Consider waiting for next-generation panel improvements if near-black performance is critical to use case
  • โ†’VRR usage may introduce noticeable flicker despite high refresh rate capability

Why would you want VRR with such high frame rate? You won't notice any stutter at high hz but you will notice VRR flicker

Comparison r/OLED_Gaming u/sammyboy1591

The LG 27GX790A-B is a matte-finish WOLED monitor that appeals to users prioritizing glare reduction and eye comfort over maximum visual pop. Community discussion reveals it as the practical choice for bright-room setups, with multiple users confirming its effectiveness at managing reflections from windows and daylight. The matte coating diffuses light sources rather than reflecting them distinctly, making it usable without cave-like room conditions. Users with blue or green eyes particularly note the WOLED subpixel layout avoids the color fringing issues reported on QD-OLED alternatives, reducing eye strain during extended use. The monitor suits those wanting OLED image quality without sacrificing ambient lighting or dealing with distracting mirror-like reflections.

Key Insights

  • โ†’Best for users with bright rooms, windows, or who prefer working with ambient daylight
  • โ†’Recommended for users sensitive to color fringing or with blue/green eyes who experience eye strain from QD-OLED subpixel layouts
  • โ†’Not ideal for users prioritizing maximum image crispness and color vibrancy above all else
  • โ†’Community consensus: matte vs. glossy choice depends entirely on room environment and personal eye sensitivity, not absolute image quality
  • โ†’WOLED technology specifically recommended over QD-OLED for users reporting headaches from color fringing

Yeah I loved the glossy colors but the reflections were way more noticeable than on the matte.

Yeah I couldn't deal with those reflections, and I like to have a bit of day light come on to not feel like a complete vampire lol

Idc if thereโ€™s 20 different light sources distorting the image, Iโ€™ve always preferred glossy screens over matte regardless of the panel type. I just find them more crisp overall, on or off. But the โ€ฆ

Comparison r/OLED_Gaming u/climacc

The LG 27GX790A-B is a 27" 1440p 480Hz OLED monitor being considered by competitive gamers upgrading from older 1080p 144Hz displays. Community discussion reveals this monitor is frequently available at significant discounts (one user secured it for ยฃ585 after discounts and cashback), making it price-competitive with 240Hz OLED alternatives. Owners emphasize its strong future-proofing value, as monitors typically outlast PC builds. The 480Hz refresh rate provides headroom for high-FPS titles like Valorant, Overwatch 2, and Apex Legends where users report pushing 400+ FPS. However, community consensus suggests the jump from 240Hz to 480Hz offers diminishing returns for competitive performance, serving more as a visual experience improvement rather than meaningful gameplay advantage due to human reaction time limitations.

Key Insights

  • โ†’Best for competitive gamers who play lighter titles capable of 400+ FPS and want future-proofing
  • โ†’Not ideal for users seeking maximum value if primarily playing demanding titles at ~250 FPS
  • โ†’Community consensus: 240Hz OLED provides comparable visual experience due to OLED's superior motion handling
  • โ†’Monitor longevity justifies higher upfront investment for users planning future PC upgrades
  • โ†’Pricing deals can make this monitor equivalent in cost to 240Hz alternatives, removing price barrier

I mean, your monitor will probably outlast your pc, so once you upgrade but still use the same monitor, it will be even better. If you have the money, why not.

broimsus 5โ†‘

Ngl, going from 240Hz to 480Hz is more of a visual experience improvement than any meaningful difference in competitive titles. The average human reaction time is probably ~300 times the difference โ€ฆ

Sgt_Dbag 4โ†‘

100%. If youโ€™ve never had OLED, 240Hz on an OLED is similar to like 360 or 480 on an IPS. It is like this because of the superior motion handling of OLED technology. You need less Hz with OLED to โ€ฆ

Quick Opinion r/OLED_Gaming u/lvl99slayer

A new owner of the LG 27GX790A discovered visible grey banding on certain backgrounds, particularly mid-tones, though it was not visible on pure black or white screens. Community consensus indicates this is normal behavior for this WOLED panel. The issue can be substantially improved through manual pixel cleaning cycles accessible in the monitor's settings menu. One owner reported successful reduction of banding after running a manual clean. However, multiple users note that some degree of grey banding will persist permanently on this panel type, especially visible in gray tones where the image may appear slightly grainy. The community is divided on whether this is acceptableโ€”some consider it inherent to WOLED technology, while others argue a brand new panel should not exhibit this issue after proper refresh cycles.

Key Insights

  • โ†’Best for users who primarily view content with black or white backgrounds where banding is not visible
  • โ†’Not ideal for users highly sensitive to uniformity issues or those working extensively with gray/mid-tone content
  • โ†’Expect to run manual pixel cleaning cycles during first weeks of ownership to minimize banding
  • โ†’Some degree of graininess in grays is permanent characteristic of this panelโ€”set expectations accordingly
  • โ†’Consider verifying panel behavior during return window, as community disagrees on whether persistent banding is acceptable for a new display

Yes. Just look at other posts regarding this monitor on this subreddit. It will likely clear up a bit over time as it runs pixel cleaning cycles. If it bothers you enough, you can run a pixel โ€ฆ

it's called grey banding and yes it is perfectly normal for a WOLED monitor. It will reduce over time with pixel cleaning but never go fully away. if that clearly bother you, you should go QD oled โ€ฆ

Comparison r/OLED_Gaming u/letired

The LG 27GX790A-B is a 27-inch OLED gaming monitor that left multiple owners disappointed despite its deep sale price of โ‚ฌ574. Users report the monitor suffers from excessive default sharpness causing artifacting and an ugly picture, dull and washed-out colors in both SDR and HDR modes, and blurry text rendering that impacts productivity use. One owner found reducing sharpness by 10 in the OSD partially resolved the issue, while another noted matte coating contributed to a grainy, dirty appearance. Multiple users returned the monitor. The experience falls significantly short of larger LG OLED TVs and other OLED panels, suggesting quality control or calibration issues rather than fundamental OLED technology limitations.

Key Insights

  • โ†’Best suited for users willing to spend time calibrating and adjusting OSD settings, not plug-and-play buyers
  • โ†’Productivity and text-heavy use cases are significantly compromised without sharpness adjustments
  • โ†’HDR performance particularly disappointing; SDR also requires Windows color management intervention
  • โ†’Factory calibration appears inadequate; budget for calibration device or accept suboptimal colors
  • โ†’Strong consensus that monitor underdelivers relative to expectations set by other OLED experiences

I also have the same monitor and turning down the sharpness by 10 on the monitor OSD fixed it for me. Text clarity was not an issue in contrast to what people say about OLED text fringing for some โ€ฆ

Tried the same monitor and returned it got a xg27ucdm, matte screens just make everything look dirty to me, or grainy, makes text hard to read. My current screen has been infinitely better

The colors being washed out might be because of Windows. You're gonna want to right click on your desktop > Display > Color profiles. And there you're gonna want to DISABLE the automatic color โ€ฆ

Troubleshooting r/OLED_Gaming u/ANutshelll

Owner of a new LG 27GX790A (480Hz 1440p OLED) experienced severe display signal loss and game freezing when launching CS2 in fullscreen using the included DisplayPort 2.1 cable with an RTX 5080. Multiple troubleshooting attempts failed including adjusting refresh rates, enabling/disabling G-Sync/Adaptive Sync, and trying different resolutions. The issue persisted across multiple DisplayPort 2.1 cables, including a certified Cable Matters 80Gbps cable. The only successful workaround required switching to HDMI 2.1, using CRU to force 480Hz by removing other refresh rates, and manually adding custom resolutions since NVIDIA Control Panel was non-functional. The monitor was unusable out-of-box with DisplayPort for this user's primary use case.

Key Insights

  • โ†’Best for users willing to use HDMI 2.1 connection rather than DisplayPort 2.1; DisplayPort currently non-functional for at least some RTX 5080 configurations
  • โ†’Not ideal for users expecting plug-and-play experience with DisplayPort 2.1 and latest NVIDIA GPUs; requires significant technical troubleshooting
  • โ†’Community finding: DisplayPort 2.1 compatibility issues appear cable-independent, suggesting monitor firmware or GPU/monitor handshake problem rather than cable defect
  • โ†’Workaround exists for stretched resolution users via CRU utility, but requires technical expertise and sacrifices multi-refresh-rate flexibility
  • โ†’Early adopter product with minimal community knowledge base; buyers should expect to self-troubleshoot

Have you tried what I have written in edit 4?

Works perfectly fine, using HDMI still, frames depend on my PC, not the monitor, depends on what game, settings, but in CS I hit 500+ easily and don't notice any stutters.

I see... However, wouldn't DSC be only very 'light' as the 5080 has display port 2.1 and the monitor also has display port 2.1 (although I read it wasn't the full bandwidth)? I think I will test with โ€ฆ

Quick Opinion r/OLED_Gaming u/phishnchips_

The LG 27GX790A is a WOLED gaming monitor featuring a new RGWB subpixel layout and matte coating, tested by a user sensitive to OLED eye strain. The reviewer found the monitor unsatisfactory due to its matte coating causing significant image quality degradation. Despite the improved subpixel layout, the coating made the picture appear hazy and blurry, rendering text unclear. The reviewer abandoned the monitor after brief testing and explicitly rejected matte OLED technology entirely, opting for glossy WOLED alternatives instead. No long-term ownership experience exists.

Key Insights

  • โ†’Not suitable for users prioritizing text clarity and sharp image reproduction
  • โ†’Matte coating fundamentally compromises OLED's inherent contrast and clarity advantages
  • โ†’Users sensitive to display haze/blur should avoid matte-coated OLED monitors entirely
  • โ†’Subpixel layout improvements alone cannot overcome coating-related image degradation
  • โ†’Glossy WOLED alternatives preferred by users seeking maximum clarity from OLED technology
