You can see that the targets had been closely matched after this process. This is a further “validation” process you can run which takes 3 minutes to complete and will produce a more thorough report, including one you can save as a PDF if you want: Related content: Monitor OLED Panel Roadmap Updates – March 2023– what’s coming in the future for OLED desktop monitors Where to Buy There are then two cleaning cycles, “image cleaning” which takes 10 mins to run, and “pixel cleaning” which will take 1 minute. It’s the “image cleaning” that is the more common and frequent minor cleaning cycle, despite being the longer to complete. The screen will prompt you to run these periodically anyway after certain amounts of usage time (4 hours of use for image cleaning and 500 hours of use for pixel cleaning), and will run the cycle when the screen is in standby so as not to disrupt your usage. dE colour accuracy – a wide range of colours are tested and the colour accuracy dE measured. We compare these produced colours to the sRGB reference space, and if applicable when measuring a wide gamut screen we also provide the accuracy relative to a specific wide gamut reference such as DCI-P3. An average dE and maximum dE is provided along with an overall screen rating. The lower the dE the better, with differences of <1 being imperceptible (marked by the green area on the graph), and differences between 1 and 3 being small (yellow areas). Anything over dE 3 needs correcting and causes more obvious differences in appearance relative to what should be shown. dE 2000 is used for improved accuracy and providing a better representation of what you would see as a user, compared with older dE methods like dE 1994, as it takes into account the human eye’s perceptual sensitivity to different colours. HDR mode performs better in this regard, with it reaching up to 700 cd/m2 peak brightness. Unlike most LCD monitors which support DisplayHDR 400 or DisplayHDR 600 certification, but usually amount to little difference, the HDR on the 27GR95QE makes a notable difference in the image quality as it is able to utilize the HDR data to a much greater effect. As such, games and movies on the monitor looked expectedly stunning, so much so that there was little difference between it and my LG C9 OLED TV.
The colour space of the screen was quite a lot wider than the sRGB reference (used for SDR content) and we measured a 126.2% relative coverage. There was over-coverage of sRGB in red and green shades, causing those to look more neon and vivid than intended. As normal with any wide gamut screen, measuring the accuracy of sRGB colours results in high dE errors, with an average of 5.0 and a maximum of 11.9. This is further exacerbated by the overly cool colour temp leaving a poorer colour accuracy than might otherwise have been offered if it had been closer to our 6500K target. Out of the box at these default settings, the screen is really not accurate for sRGB / SDR content. Next, the monitor has a wide 98.5% DCI-P3 gamut coverage, resulting in rich and vibrant colors. This is equivalent to around 135% sRGB gamut size, so content made with sRGB color space in mind will be over-saturated. Some users prefer the extra vibrancy provided by the over-saturation, but you can also clamp the gamut down to ~100% sRGB in case you prefer accuracy. At all brightness levels in SDR, there is no need for the screen to use ABL, so you get a consistent brightness level no matter what your content is. That’s great news on an OLED panel as it’s annoying to see changing brightness as you move windows around or look at different content where ABL is used. A lot of fuss has been made about the screen being “dark” but that isn’t really a problem for office and general uses in our opinion, not unless you’re using the screen in a very bright room or are simply used to having a very bright LCD monitor pumping out 300 nits+. It’s perhaps more of an issue for gaming and video where maybe you want a brighter screen or use the screen from a further viewing position. Text Clarity and Sub-pixel structure

The 27GR95QE features a more traditional monitor-like matte anti-glare coating, as opposed to a glossy panel coating like you’d find on popular OLED TV’s including the LG 42C2. This seems to be the panel coating of choice for OLED screens aimed at desktop use, and it makes sense when you think about the typical use cases for desktop monitors compared with TV’s, and the fact that this type of panel coating has been used for many years in the LCD market. Reflection handling The performance is very similar in all other modes except for ‘Vivid’, which can reach up to ~400-nits for 25% and smaller white window sizes, but drops to ~200-nits at around 50%, and down to ~130-nits at 75% – 100%. Therefore, we don’t recommend using the Vivid mode in SDR unless playing games or watching videos as the jumps in brightness will be annoying during everyday use. It also has a too high color temperature, resulting in a bluish tint. SDR
The LG UltraGear 27GR95QE will be available in the UAE sometime in April. The monitor will retail at AED 4,199. The Verdict The monitor also supports 4K 120Hz HDR and VRR on the PS5 and the Xbox One/Series S/X. Price & Similar Monitors First the BenQ Zowie XL2566K which we would rate overall as being slightly faster than the LG, with a slightly sharper and clearer image. This becomes a little more apparent in certain situations like with scrolling text as well, but unless you were comparing them side by side it would probably be hard to separate the two for most people. If you’re after the absolute clearest motion for Esports and competitive gaming, then something like the BenQ with its 360Hz TN Film panel has the slight edge.We’d argue that reflections on glossy panel are likely to be far more problematic to most people than a small impact to the contrast ratio from an AG coating for what is at the end of the day specifically designed to be a desktop monitor. Remember, this isn’t designed to be a TV, it’s not designed to be used in a dark lounge with carefully controlled lighting for relaxing night time viewing. It’s designed to be used as your desktop monitor, throughout the day, in a normal lighting setup where you have windows, overhead lighting and lamps around.
Gamut coverage – we provide measurements of the screens colour gamut relative to various reference spaces including sRGB, DCI-P3, Adobe RGB and Rec.2020. Coverage is shown in absolute numbers as well as relative, which helps identify where the coverage extends beyond a given reference space. A CIE-1976 chromaticity diagram (which provides improved accuracy compared with older CIE-1931 methods) is included which provides a visual representation of the monitors colour gamut coverage triangle as compared with sRGB, and if appropriate also relative to a wide gamut reference space such as DCI-P3. The reference triangle will be marked on the CIE diagram as well. Unlike most gaming screens, including all the other 27″ 240Hz OLED monitors announced so far, the LG 27GR95QE includes support for hardware level calibration. With the use of a compatible calibration device, you can calibrate the screen at a hardware level, stored to the monitors internal LUT directly, and therefore active in all applications, multimedia and games. You aren’t reliant on normal software level profiling and colour aware applications; the accuracy and settings apply everywhere.Compared with the 360Hz IPS panel of the Asus ROG Swift PG259QN we would say the LG has the edge though. Despite the higher refresh rate of the Asus, it has some issues with response time, notably some slower transitions from light to dark shades common on IPS panels and causing a bit of pale smearing. And also a bit of pale overshoot as the response times are pushed hard to keep up with the frame rate. Admittedly this was one of the first gen 360Hz IPS panels and other reviewers have noted that more recent offerings are a bit faster (e.g. the Asus ROG Swift PG27AQN – 27″ 1440p, 360Hz as reviewed by Monitors Unboxed) which would bring the performance closer to the LG OLED panel. But certainly compared with most of the existing 360Hz IPS panels we think the LG 240Hz OLED panel has the slight edge in motion clarity, even though it has a lower refresh rate. Lag In our original testing only the ‘vivid’ mode showed any real improvement in HDR peak brightness, reaching up to 792 nits, but only at the expense of an overly colour colour temp, now measured at 9252K. Even this wasn’t reaching the 1000 nits advertised, and we have no idea where that spec came from really. We couldn’t achieve it from our testing. As we said above, the newer April 2023 firmware made some adjustments to the Gamer 2 preset mode which we have added to the table above, making that much cooler now and reaching 882 nits max, but at ~8900K colour temp. Even this “cheat mode” didn’t help it reach the advertised 1000 nits. The UltraGear OLED 27 has competitive games down, but it also has cinematic games nailed. OLED and the stellar HDR experience it brings means you can enjoy games like Cyberpunk 2077and Horizon Zero Dawnwithout missing out. I’ve never encountered a monitor that makes perfect sense like the UltraGear OLED 27 does. It doesn’t always hold up on the spec sheet, but sitting down in front of the monitor consistently reinforced one idea: this is one of the best gaming experiences you can have right now.
This confirms the measured results. Note that the highest colour error is in red, which is what we’d seen after software profiling too as the screen seems to struggle with that pure 100% red colour.The LG 27GR95QE-B is compatible with FreeSync and G-Sync, so you don’t have to worry about tearing and stuttering. This duality is essential for high-end monitors, so you don’t have to ditch it if you decide to switch to either AMD or Nvidia GPUs. Its input lag is below 3ms at 240Hz, so it is only a few notches slower than this 360Hz monster. Thoughts on the LG 27GR95QE-B We were disappointed though with the brightness capability of the screen in HDR content, not getting anywhere near the spec advertised, even in overly cool preset modes. If you like the extra pop of a very bright HDR experience, then you will find higher elsewhere, but you probably need to look at Mini LED LCD screens instead of OLED for the brightest HDR performance. On the plus side the HDR setup was pretty decent and accurate which was pleasing, as that’s one mode you can’t hardware calibrate sadly at the moment. The 240Hz refresh feels like a future-proofing, especially with this new generation of Nvidia and AMD GPUs just hitting the market. 1440p has long been the sweet spot for PC gaming; while 240Hz and 360Hz 1440p monitors do exist, this is our first time seeing 240Hz 1440p on an OLED panel. LG Display’s W-OLED panel uses a WRGB subpixel layout, which adds a white subpixel to the conventional RGB layout for increased brightness. This causes minor fringing on small text and thin lines, which some users might find a bit annoying, but it’s not noticeable in games and videos.
