The matte anti-glare (AG) coating that LG have opted for is going to be controversial for sure, as the topic it was when we reviewed the Asus PG42UQ and other matte coated OLED screens.Whether or not it’s a good thing might also depend on your other uses somewhat. For this ‘office and general use’ section of the review we definitely preferred this AG coating over a glossy coating like that found on something like the LG 42C2. It does a really good job of eliminating reflections that you’d get from glossy coatings and diffuses light sources nicely. It looks and feels a lot more like a normal desktop monitor to use, and we think this is a good thing for the majority of people for office and general uses. These kind of environments are unlikely to be light controlled and you wouldn’t want to be working in a dark room for office work. You’ll have various lights and windows to worry about and we felt that the AG coating was a good thing for these uses. In early April 2023 LG released an updated firmware for the 27GR95QE designed to supposedly help improve screen brightness. We have unfortunately had to return our screen sample, but our friends over at Monitors Unboxed have updated the firmware on their screen (done via the LG OnScreen Control software) and re-tested brightness in both SDR and HDR modes. The Gamer 2 HDR mode has now been changed to be much cooler than before, reaching around 8900K in their measurements. This does however deliver a brighter image, reaching up now to 882 nits max (2% APL) but at the cost of a much cooler and bluer image. This is a common cheat method on OLED screens to try and reach a higher peak brightness, and we would not consider this useful unless you specifically like a very cool looking image. Where is the 1000 nits peak HDR brightness? Peak brightness in default Gamer 1 HDR mode, with a white point close to 6500K at 6847K The Screen Saver function seems a sensible one to leave turned on, as it will turn the screen off if it detects no change to the image for an extended period of time. We never saw this happen unnecessarily during any normal usage, even on pretty static desktop applications. It worked as intended in our usage when we left the screen alone fully.

If you want to improve the colour accuracy further, the 27GR95QE works with LG’s Calibration Studio software though you will need one of the listed colourimeters to use. While the achieved colour coordinates are listed there is no easy measurement for the colour gamut coverage or confirmation that it has been matched really. It would have been nice to include a % sRGB coverage here to make it easier for the user to validate, perhaps an absolute figure and a relative figure, which would then reflect if there’s any over-coverage still. Actually we spotted an error with the reporting of the blue coordinates above too. You can see the target was 0.1500, 0.0600 and the software says the result was 0.1490, 0.1490. That second “0.1490” is wrong, and thankfully it hasn’t been calibrated to that, otherwise we’d end up with a massive under-coverage in blue shades and only 81% sRGB gamut! It’s being reported wrong in the results above.With over a week of screen time with LG’s new 27” OLED monitor, I can confidently say that this is a stellar product, and absolutely is the upgrade one should consider. Of course, OLED panels do come with one major caveat, and that is the less than average standard brightness, which could struggle in showing bright images under well-lit conditions.

In SDR mode the luminance range of the screen is limited compared with LCD monitors, with a maximum brightness measured at 192 cd/m 2, which was close to the advertised 200 cd/m 2 which was pleasing. Most LCD monitors however can reach 300 – 500 cd/m 2 easily for SDR content and so on first glance, this might appear to be very limiting on the 27GR95QE. If you are used to using a very bright monitor or running at high brightness settings, you will almost certainly find this screen to look dark by comparison. The ‘Screen move’ setting shifts the pixels a bit from time to time if you enable it, and will be familiar to anyone who has used an OLED TV before. Personally I find these features annoying for desktop and general use where you might notice the screen move a bit, but for gaming and multimedia you’d be hard pressed to notice it. But then again, it’s of less value for those kind of dynamic uses anyway. To help mitigate the risk of image retention and burn in, you might want to have this turned on but at least LG give you the option to turn it off as well. The pixels have been “over-provisioned” on this screen, so while the image shifts a bit by a few pixels, you never lose any of the actual image off the edges. There is no explanation of what the 4 different modes do in the user manual, so we have no idea how they differ. We tried a couple of them and found the occasional shifting of the image annoying for desktop use personally. Note: we turned off “Smart Energy Saving” from the OSD menu which could otherwise impact screen brightness. 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.HDMI-VRR is supported thanks to HDMI 2.1 from both consoles. ALLM is unfortunately not supported, and although the input lag will be consistent across all preset modes (the main reason for this setting is to turn a TV in to its game mode for lower lag), it could have been useful if it had switched to a gamer preset mode, as opposed to perhaps your normal working mode like sRGB or a calibrated preset. 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. Features a 240Hz, 2560 x 1440, OLED display A perfect combination of speed, size, and picture quality that makes for a highly versatile monitor 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. There are 7 monitors using the same panel with different design, features, connectivity options, warranty and pricing.
