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. 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. As discussed in our detailed article about Response Time Testing – Pitfalls, Improvements and Updating Our Methodologywe are using an improved and more accurate method for capturing G2G response times and overshoot, based on figures that are more reflective to what you see visually on the screen in real-World usage. Our article linked above talks through why this is better and how we arrived at this improved method in much more detail.
Brightness isn’t the main draw here, though. It’s contrast. LG claims the monitor can reach peak brightness of 1,000 nits, but only for 3% of the screen. I measured a max brightness of 600 nits, but that was with HDR cranked. That sounds high, but the monitor won’t normally get that bright. In SDR, it topped out at just over 250 nits, which is fairly dim for a monitor released in 2023. The fringing is not as noticeable as it is on monitors with a triangular subpixel layout, such as that of the Dell AW3423DWF with a QD-OLED panel, so except for those particularly sensitive to this, most users won’t even notice anything wrong with text rendering on the LG 27GR95QE unless looking at small text and fine details up close. Aside from LG's first OLED display made for gamers, there are also 4K Nano IPS and QHD Nano IPS monitors to choose from. LG provide a 2 year warranty for this screen although do not really talk about image retention or burn in cover, other than to say that the warranty does NOT cover “Burned-in images resulting from improper usage as described in the user manual”– but improper use is a pretty vague term. This may make it difficult to claim under the warranty should you ever run in to any image retention issues, so we would advise some caution depending on your usage type and habits, and your risk tolerance. GamingIn 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. Peak brightness in this default mode reached a maximum of 609 nits in our tests, and that was on a 10% APL window. It was also at approximately that brightness for smaller APL window sizes, but sadly didn’t reach higher, and certainly nowhere near the spec of 1000 nits from LG. We will examine other modes and whether you can get higher peak brightness in a moment. At a full white windows (100% APL) the sustained brightness was only 141 nits, which was quite a bit lower than a 100% window in SDR for some reason (~192 nits). We would have liked to have seen better HDR brightness here really. Newer firmware April 2023– no change to brightness Life's about more than having the latest technology. It’s about the experiences technology creates. From TVs and refrigerators to laptops and computer monitors, LG UK delivers home electronics that let you embrace life and prepare you for its greatest moments. The monitor also supports 4K 120Hz HDR and VRR on the PS5 and the Xbox One/Series S/X. Price & Similar Monitors
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 We measure the screen at default settings (with all ICC profiles deactivated and factory settings used), and any other modes that are of interest such as sRGB emulation presets. We then calibrate and profile the screen before re-measuring the calibrated state. On the Xbox Series X there is also a 1440p setting which would have been better to prioritise refresh rate again. However, that mode annoyingly cannot support HDR from the console, and so if you are playing an HDR capable game (and most are nowadays) you would be better running at 4K output to the screen, where HDR is then supported from the console. Image retention, or burn-in is still a prevalent issue with OLED displays despite the resilience of newer panels. As such, some care will need to be taken to maintain optimal image quality on the 27GR95QE. While I wouldn’t go to the extent of baby-ing it all the time, leaving static images on the screen for extended periods of time could result in some burn-in issues. If you are a heavy Windows user, you might want to set the taskbar to auto-hide, and if you are watching lots of sports, or playing a game with a lot of static HUD elements, you might want to give the screen a break now and then with other kinds of content so the OLEDs don’t ‘set in’ on a particular color. The LG 27GR95QE monitor has a high 240Hz refresh rate, which when paired with OLED’s instantaneous pixel response time speed results in incredible motion clarity without any ghosting or pixel overshoot.
Thoughts on the LG 27GR95QE-B
The 27GR95QE is compatible with AMD FreeSync and Nvidia GSync, so you don’t have to worry about screen tearing or stuttering of any kind, regardless of the brand of graphics card you have in your system. You’re meant to control the monitor with the included remote, but even with that, the UltraGear OLED 27 runs into issues. For starters, the battery slot on the remote requires a screwdriver to get open, and LG doesn’t include the coin battery you need to power the remote. This wouldn’t be a problem if you could control the on-screen display with the button on the monitor, or if LG had included the battery, which very few people are likely to have laying around, but neither of those things are true.
