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.
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. The bezels surrounding the OLED panel may not be the narrowest I’ve ever seen, but they only measure 8mm at the sides and 10mm at the bottom, so I’m not complaining. All up weight is 7.35Kg with the stand accounting for 2.3kg of that. 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. Information about the minimum amount of time, in which the pixels change from one color to another. Very often the manufacturer provides the response time for transition from grey-to-grey (G2G).
LG 27GR95QE-B Specifications
When using VRR, the pixel response time performance is perfect regardless of the refresh/frame rate as there’s no need for different overdrive modes. As for the menu options themselves, it's pretty disappointing to see that LG has limited what you can do without the remote. The only options you can change with the power button menu are power, input, volume and brightness. That means, for example, that if you lose your remote you can't switch modes on this monitor, turn Adaptive Sync on or off, change languages, enable an FPS counter, etc.
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. Size class of the display as declared by the manufacturer. Often this is the rounded value of the actual size of the diagonal in inches. 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. We uploaded the latest brightness measurements and uniformity photos for the Accelerated Longevity Test. 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.You can see some pursuit camera photos above capturing real world perceived motion clarity of this 240Hz OLED panel compared with the 138Hz Asus PG42UQ, the 120Hz LG 42C2 and even the fastest refresh rate monitor we’ve had chance to test – the Asus ROG Swift PG259QN with a 360Hz refresh rate IPS panel. We uploaded the initial brightness measurements and uniformity photos for the Accelerated Longevity Test.
This is based on the 45″ ultrawide OLED panel from LG.Display used in the Corsair Xeneon Flex monitor, but there’s no reason to think that the 27″ OLED panel being used in the new LG 27GR95QE-B is any different. So we would expect excellent motion clarity from this future screen for sure, on par or better than anything you can currently find in the LCD space which tops out at 360Hz at the moment. Hopefully that gives you an idea of what to expect. Screen Coating 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 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. Related content: our video guide to the best settings for the LG 27GR95QE Calibration (Software Profiling) 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.

Dimensions, weight and color Information about the dimensions and the weight of the specific model with and without stand as well as the colors, in which it is offered to the market. Width 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. The LG 27GR95QE also features Hexagon RGB lighting at the rear with adjustable colors and lighting patterns. In a dark room, the LEDs are even strong enough to reflect off of the wall and create atmospheric ambient lighting. We can also compare the motion clarity of the 27GR95QE here against some 360Hz LCD screens we’ve reviewed. You can see that actually despite the lower refresh rate (by 33%) the motion clarity is very similar here from the 240Hz OLED panel. There is a ratio of approximately 1.5:1 when it comes to motion clarity between an OLED screen and an LCD screen, thanks to the near-instant response times. So you get a motion clarity in practice beyond what you might expect from the refresh rate number. We have compared the LG against two 360Hz screens here.
Often even a higher peak luminance can be achieved under certain conditions. For example, when a smaller area/APL of the display is used for showing a bright object, when a bright object is displayed for a short time, etc. 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 coating does a very good job of reducing reflections and handling external light sources like windows and lamps and we noticed much better reflection handling (no surprise) than glossy panels like the LG C2. Like normal matte coated monitors, there were very minimal reflections of lamps, windows and lights at all, and this made the screen very comfortable to use in office environments and in daytime usage. In our opinion this is far more suitable for a desktop monitor than a glossy panel coating. If you really prefer glossy, you may want to consider looking at the Dough Spectrum ES07E2D which is coming out later this year, and is basically a glossy version of this panel. Image clarity and graininessThis 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. Adobe RGB (1998) is a color space, developed by Adobe Systems in 1998. It has a wider gamut than the sRGB (mainly in the cyan-green range of colors) and is widely used in professional printing. 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 But via the remote control, the main menu has a reasonable range of options to play with. There’s a wide range of preset modes you can select from and customise, including two hardware calibrated modes if you have a compatible calibration device. 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.
