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.
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 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. If you’re a proud new owner of the LG 27GR95QE, or you’ve got one arriving soon, we have a guide for you to help you get the most out of the screen. This will guide you to the optimal settings for desktop use, gaming, SDR and HDR. You can follow our video guide on our YouTube channel here, or from the embedded version above. Other Useful Links The maximum peak brightness we’d measured in the Gamer 1 mode which was configured to be close to a 6500K white point was around 609 nits. Not bad, but then also not great for a modern HDR display. Certainly nowhere near the peak brightness spec of 1000 nits that LG promote, and quite a long way off modern Mini LED LCD monitors which can typically reach 1000 – 1500 nits. This 609 nits we measured was achieved at a white point close to 6500K in those modes (6847K measured) at least.#

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.
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. They confirmed there was no change at all to HDR brightness in Gamer 1 mode, which has the ~6500K colour temp. It’s that combination that makes the UltraGear OLED 27 so striking. The 240Hz refresh rate is easily beaten out by the recent barrage of 360Hz screens we’ve seen, like the Asus PG27AQN, but it’s still much higher than you see on a typical gaming monitor. Combined with the response time, motion clarity can reach the levels of a 360Hz panel, making it a great option for competitive games like Overwatch 2, Rainbow Six Siege,and Valorant. 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.Competitive gamers might also consider the ASUS PG27AQN with a 27″ 1440p 360Hz IPS panel. Due to its 360Hz refresh rate, it offers a bit lower input lag and smoother motion clarity, but the motion is not as clear and you don’t get proper HDR support. Conclusion This is also the first sensible monitor-sized OLED panel released (with a high refresh rate above 175Hz which was the previous max) and is bound to attract a lot of interest. It’s 27″ panel (well, 26.5″ to be precise) offers a common 2560 x 1440 resolution, a wide colour gamut with 98.5% DCI-P3 coverage quoted, and even support for hardware calibration. Being OLED it’s well placed to handle HDR content with its per-pixel dimming, and it has a quoted 1000 nits peak brightness spec. This is made possible through the use of LG.Display’s latest generation “META” OLED technology, including MLA (Micro Lens Array), which you can read a lot more about here if you’re interested. 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.
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.
Display
The main competition it has is the Alienware 34 QD-OLED, which says a lot about how excellent the UltraGear OLED 27 really is. LG’s advantage here is a slightly lower price and much higher refresh rate, finally bringing competitive and cinematic gaming experiences in balance. Gradient handling was good though with no visible banding issues, and only minor gradation in darker tones. sRGB Emulation Mode That’s annoying, but it’s an easy problem to solve. What the UltraGear OLED 27 gets right is adjustment. Ironically, you don’tneed a screwdriver to set up the sturdy stand, and it enables just shy of four-and-a-half inches of height adjustment, 20 degrees of swivel, 20 degrees of tilt, and the ability to turn the monitor vertically. 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.

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 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.

In that bottom section though we have measured the colour accuracy of Adobe RGB colours, which is a colour space commonly used in professional and photography markets. There is decent absolute gamut coverage of Adobe RGB at 96.4%, but there’s still some over-coverage in some green, and particularly in red shades. Accuracy of the colours was still poor, with dE 4.9 average (max 11.9), again impacted by the too-cool colour temp. If you did want to work with Adobe RGB content, you’d really want to be able to calibrate the screen with a calibration device, to closely match the Adobe RGB reference colour space, and improve the colour temp and colour accuracy. By default, and certainly at these out of the box settings, the screen is not accurate for work with this content.
