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. The LG 27GN850’s responsiveness is its most impressive characteristic since it’s practically blur-free. Setting monitor’s overdrive to its Normal setting is all you need to avoid the already minimal persistence that shows up in contrasting transitions. The Fast and Faster levels of this feature are unusable since they add noticeable overshoot or advanced ghosting. Thankfully, its very easy to correct the LG 27GN850’s color with just a few tweaks in the OSD. Manually calibrating can get a dE average of 0.73 which is better than the old model. Calibrating with a colorimeter can get even better results, but its not necessary since the OSD tweaks are effective enough.

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. There are various panel technologies. Each has its own specific features - viewing angles, color reproduction, response time, brightness/contrast, production cost, etc. The image quality depends directly on the type of the display panel used. Next, LG have optimized their overdrive to increase performance and reduce overshoot, something we'll be able to measure shortly. It's still a 1ms class monitor according to LG, but just a "better" 1ms.

Clearer, Smoother and Faster

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 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. 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 operating humidity shows the acceptable level of humidity, in which the display will function flawlessly. It sets a lower and an upper humidity level for safe operation and is measured in percentage. 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 next step is a full calibration, which we achieved using DisplayCAL. As expected, sRGB results are very strong, and for P3 it's also quite good aside from some very small problems right at the tip of the gamut where that last 2-4% isn't covered. Viewing angles are still excellent, so while the 27GP850 may have TN-like contrast, it does offer a much better viewing experience overall. Uniformity on my unit was good without being amazing, not too different from the 27GL850. There was a bit of IPS glow with my model, although not as much as with my 27GL850, and this does tend to vary from unit to unit so whatever I report here may not be what you experience yourself. Like with LG's previous display, there is also a crazy fast "Faster" mode which is designed specifically to hit a 1ms response time. The best result we achieved is 1.25ms, so that claim is accurate, however it's in a largely unusable mode due to its inverse ghosting. Overshoot is significant, and while the average response has improved to 2.88ms, cumulative deviation is higher in this mode compared to the previous mode, indicating the balance of performance has swung too far into the "inverse ghosting" zone. 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. WidthNotably, response time performance is better. Depending on the metric and refresh rate tested, the LG 27GP850 is anywhere from ~5 to 25% faster than the 27GL850. Combined with a higher refresh rate at 180Hz, this new display has visibly superior motion clarity and lower input latency. 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.
