About this deal

The storage temperature shows the range from a minimum to a maximum temperature, within which storing of the display is considered to be safe. The operating temperature shows the safe temperature range (from minimum to maximum), within which the display will function flawlessly. Outside this range it might operate improperly and/or fail entirely.

Now the ideal solution would have been to implement variable overdrive to switch between these settings depending on the refresh rate, but LG hasn't implemented that here. In a sense there are two optimal overdrive modes, rather than the ideal situation which is a single optimal setting. The LG 27GN850 doesn’t have speakers, but that’s okay since its intended audience will most likely use gaming headsets. Built-ins are also part of the handy extras you can get from a high-end monitor, but it is still forgivable if they aren’t included. Display and Performance Brightness is improved with the 27GP850 compared to the 27GL850, the new model does around 450 nits compared to 350 with the prior generation, so that's a solid improvement that will assist those in bright environments. Minimum brightness is outstanding, at below 30 nits, great for those that like a dim monitor for gaming at night. Information about the number of pixels on the horizontal and vertical side of the screen. A higher resolution allows the display of a more detailed and of higher quality image.

Moving into color performance now and like LG's previous Nano IPS displays, the 27GP850 also comes with a rated 98% DCi-P3 coverage, which in our testing measured in at 96%, among the best coverage of P3 that we've measured. Updated to Test Bench 1.2, resulting in changes to the results and scores with the Response Time and Input Lag. Added tests for Console Compatibility and macOS compatibility and made minor changes to other tests, which you can see in our Changelog.

Average grey to grey performance, measured across the refresh range, is also an interesting story. The inverse ghosting rate is higher than with the 27GL850, but it also provides a 30% faster response time on average. In general this makes it a bit faster on average than other current-gen fast IPS panels like those found in the MAG274QRF-QD, AW2721D and PG329Q. The LG 27GN850 offers more than 100% sRGB easily, but the monitor’s DCI-P3 only reached 82% which is still fairly wide. The screen looks punchy and vibrant, but its default accuracy average of dE 2.89 could use some improvements. Its still within acceptable limits, but the score is slightly worse than its predecessor.Ergonomics Information about the ergonomic functions - height adjustment, swivel angles, tilt angles, etc. VESA mount

Each of these computer-monitors has different resolutions, sizes, panel type, connectivity, and color gamut. The most widely used panels are those with 6, 8, and 10 bits for each of the RGB components of the pixel. They provide 18-, 24-, and 30-bit color, respectively. It is noticeable that the brand did not spare any expense when it comes to the LG 27GN850’s build quality. Its plastic panels don’t feel cheap so they are sturdy, plus there are no cosmetic defects on any of the monitor’s sides or edges. The stand also doesn’t wobble, but the cable hook feels a bit flimsy which may become a problem if you regularly change cables for different devices. However the most recent wide gamut IPS displays like MSI's MAG274QRF-QD take things one step further, with in excess of 80% Rec. 2020 coverage. This allows the MSI monitor to also support full Adobe RGB coverage, which the 27GP850 does not. Having Adobe RGB coverage in addition to P3 may be useful for some creative workloads, so if that's important to you then other panels will be better than the 27GP850. Despite this, LG are still providing quite a wide gamut.However I also think that's being a bit unfair to LG. Usually when I talk about displays not delivering a single overdrive mode experience, it's because each mode is unusable at a certain point in the refresh range. That could mean decent performance at 144Hz but severe inverse ghosting at 60Hz. That's not really the case with the 27GP850, and the differences between the Normal and Fast modes are small overall. I actually found it quite hard to decide which mode is better for adaptive sync gaming, ultimately I settled on the Fast mode but overall it's a case where buyers can choose to either prioritize low overshoot with the Normal mode, or speed with the Fast mode, and get a pretty good experience across the board. A major selling point of the LG 27GP850 is also its proper, functional sRGB emulation mode, which eliminates oversaturation when viewing standard content like YouTube videos or games. Many wide gamut monitors stuff this up and you have no choice but to view an oversaturated image in some instances. Full praise to LG for thinking of both gaming performance and color accuracy and executing well in both areas. The basic fundamentals are the same: this is a 27-inch 2560x1440 display using LG Nano IPS technology. Same 98% DCI-P3 gamut coverage, same adaptive sync support with G-Sync and AMD FreeSync. But there are three major additions that make this more than just a refresh. The maximum number of colors, which the display is able to reproduce, depends on the type of the panel in use and color enhancing technologies like FRC. In terms of design, this is your standard LG UltraGear monitor. The stand has received an overhaul, so we're not getting the sliding-cylinder design for height adjustability, but the new version is similar to LG's 2020-series monitors. The stand pillar and base use plastic for their outer materials, it's got this new more angular pillar that looks quite good, and then V-shaped legs.

To be clear, it doesn't need that higher refresh rate to be better, even comparing 144Hz to 144Hz, the 27GP850 is better in terms of response performance, a product of tweaked and improved overdrive modes. The brand skimped out on the LG 27GN850, but you still get DisplayPort 1.4 and two HDMI 2.0 ports for your PC and gaming consoles. However, they removed the USB ports on this iteration, so you lose a bit of functionality. That’s not a major loss, but those USB ports could come in handy in some situations, especially if you are particular with cable management. LG continues to provide impressive monitors for the gaming market. With the LG 27GP850, they company hasn't simply re-released a previous product with a few enhancements but LG has clearly assessed the market, noted that some newer IPS monitors were offering better performance, and stepped up their game with their 2021 27-inch 1440p monitor. This has led to several improvements over the prior model.I also quite like how easy it is to access the 27GP850's ports on the rear, where you'll find a DisplayPort, two HDMI connectors and a couple of USB ports. This complicates wall mounting somewhat - this display does have a VESA mount - but I feel the ease of access is worth it. The overall rear design is nice, and I'm glad LG hasn't changed it substantially from previous monitors. 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. When looking at cumulative deviation, we do see an improvement for the 27GP850, it now sits firmly among those new IPS panels we've just been talking about, although not generationally ahead. In comparison, last-gen versions like 27GL850, S2721DGF and AG273QXP all sit in the 580 to 540 range in this metric. So the 27GP850's result of 521 is in the range of 5 to 10 percent better, not a huge improvement but decent for what appears to just be overdrive tweaks, rather than an entire overhaul of LG's IPS technology - and it's doing this without variable overdrive. 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.
