In the bottom section we compared the screens native colour gamut against common wide colour gamut reference spaces. The coverage of DCI-P3 is very good, at 97.4% absolute coverage being slightly under (but very close to) the spec of 98.5%. There was very little over-coverage of DCI-P3 too (100.6% relative), so the screen is very close to that reference space, which is good news should you need to work with any content in that space, often used in HDR content creation and consumption. You can see the recommended OSD settings above that go along with this profile. Our calibrated ICC profilefor this display is available now for our Patreon supportersand will be added to our main database in the coming months. Hardware Calibration The stand includes tilt, height, swivel and rotate adjustments. Connections and Hardware Calibration Support The Vivid HDR mode can reach up to 800-nits for 3% and lower sizes, 700-nits for 10% and 130-nits for 100%, but it over-exposes some bright parts and has a bluish tint. Either way, it falls short of the specified 1000-nit peak brightness. LG plans to release a firmware update in April to improve the brightness performance. HDR
The emulation of the smaller sRGB colour space also worked nicely here. It went slightly too far and left us with a 95.4% coverage, but overall this was perfectly acceptable for a gaming and multimedia screen like this. With the screen now running in sRGB mode, and with a corrected colour temp too, the accuracy of sRGB colours was very good, massively improved from the default mode and now with a dE average of only 1.4. A few shades showed a slightly higher value up to dE 3.2 but only just getting in to the area where you might notice some slight visual differences in practice. This was a really good mode to use for accurate work with SDR and sRGB content, if a little limited potentially in brightness range for some. Optimal OSD Settings (Wide Gamut mode) Enabling Windows ClearType (top photo) can help improve the text clarity, but it can introduce some of the color fringing. This means you either have to choose between sharper text with color fringing or worse text clarity without the fringing. These photos are with Windows 10, and you can see what it looks like in Windows 11 with ClearType on here, and with ClearType off here. We will not go too much in to potential concerns around lifespan of the OLED panel, colour shift, dark spots or image retention/burn-in here. You can read our OLED Displays and the Monitor Marketarticle for more information about those potential issues. As a desktop monitor if you are going to use the screen for many hours per day, some of these things might become an issue in time. In our fairly short period of time testing and using the screen we noticed no issues in any of these areas. The percentage of the approximate area, taken by the active part of the screen, to the total front area. The LG 27GR95QE-B has okay text clarity, but it's worse than other 27-inch, 1440p monitors. This is because of its RWBG subpixel layout, as computer programs don't render text properly with this layout. This results in some color fringing around text, and while it isn't the worst case of color fringing, it can be distracting if you're sitting close and you notice text clarity issues easier. The matte screen finish also makes text look a bit hazy.Doom Eternal is an extremely fast-paced game that can push your reflexes to the max. I can’t say this monitor made me play better, but it certainly didn’t hinder me. No matter how much was happening on the screen or how fast I was moving, the UltraGear 27GR95QE-B never stuttered. Zipping across New York City in Marvel’s Spider-Man for PC was also seamless and smooth. LG UltraGear OLED 27 review: Interface The screen comes out of the box in the ‘Gamer 1’ preset mode and at maximum 100% brightness. The screen was tested here in SDR mode by the way, and we had disabled ‘Smart Energy Saving’ in the OSD menu. Another problem I often found is that the HDR can be a little inconsistent, and I found that it tended to oversaturate the colors in a distracting way. I left it off because I would much rather play with good color on a darker screen than be too bright and blown out.
The 4K content I found on YouTube looks as crisp and colorful as any of the games I tested. A Dolby Vision video called “Beauty of 4K HDR” showcases colorful animals, environments and even people in body paint. Not only are the colors distinct and vibrant, but the monitor does an exceptional job of showing off small details like a lizard’s scales or a plant's leaves. The static contrast shows the ratio between the brightest and the darkest color, which the display can reproduce simultaneously, for example, within one and the same frame/scene. The storage temperature shows the range from a minimum to a maximum temperature, within which storing of the display is considered to be safe. Note that in the Gamer 1 preset mode, the contrast setting in the OSD is at 60% by default, but considering it is set at 70% in most other modes, including the default “calibration” profiles and the sRGB mode, this seems to be a better optimal setting for contrast. Visually it only makes minor difference though in greyscale rendering and shadow detail. We prefer to change this to 70% to match the more accurate preset modes on the screen for this section. 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
This LG is a killer display that doesn't shine as bright as we'd like.
For those who want to use the full wide gamut of the screen, we also experimented to see what the best we could get out of the screen was, with only simple OSD adjustments. This should, if nothing else, allow us to correct the overly cool default colour temp, and from there improve greyscale and colour accuracy somewhat. As much as I am impressed by the picture quality, the LG can't escape the common problem that plagues some OLED gaming monitors: brightness. In my testing, the OLED's non-HDR peak brightness sits just above 200 nits which is frankly abysmal. LG claims you can get around 800 nits with HDR on, but will only apply to small, bright objects. So, it will be gaming-relevant, but you can't expect anything close to the brightness you'd get from a screen that can actually do 800 nits full screen. The LG 27GR95QE-B renders more than 100% sRGB and 98% DCI-P3 for stunning color in games and movies. Its default accuracy isn’t great when it is measured against the sRGB gamut, with its deltaE average reaching 3.71. However, that changes if you test it relative to DCI-P3 with an excellent dE average of only 0.81. Using the monitor’s sRGB mode did not help much, but it did limit the dE score to 2.51, which is better and more balanced. The LG UltraGear 27GR95QE will be available in the UAE sometime in April. The monitor will retail at AED 4,199. The Verdict
Great Deal
