The LG 27UP850-W is a fantastic 4K monitor for those who want a flexible and high-quality screen. Its IPS panel is capable of eye-popping color quality so it can be used for entertainment or professional purposes. We also liked the upgrades it received, starting with its powerful 96-watt USB-C port which can charge high-spec laptops without breaking a sweat. Desktop monitors and smart TVs experience a latency/lag in visualizing the information. The time in milliseconds that the display needs to visualize the signal input. Information about the maximum vertical viewing angle, within which the image on the screen is of acceptable quality. Another upgrade we liked on the LG 27UP850-W is its speakers which now have 5 watts of power. They can get decently loud compared to other built-ins and they are capable of better clarity along with some semblance of bass. Headsets and desktop speakers will always sound better, but it is nice to have improved monitor speakers on the side. Display and Performance 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).
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 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. The LG 27UP850-W renders 100% sRGB and around 96% DCI-P3 for excellent vibrancy in SDR and HDR. Its default accuracy is great since the average is only at 1.89 so users won’t see color errors in any scenario. Calibrating the device isn’t necessary since it looks like LG had that covered from the factory.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.

The LG 27UP850-W has an acceptable pixel response time, but the 60Hz limitation is noticeable in some instances. Using the overdrive is essential, but we can only recommend its Fast level since the maximum will induce overshoot. Doing so will clean up the visible trailing and persistence, but it is still not comparable to a dedicated gaming variant. The ratio between the horizontal and the vertical side of the display. Some of the standard and widely used aspect ratios are 4:3, 5:4, 16:9 and 16:10. 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.As for input lag, the Time Sleuth reported just 2.1ms of on display latency, and I’m happy to report that my new input lag testing mode for the response time tool reports a decent 7.5ms for the on display latency. The discrepancy there is down to the refresh rate taking so long. The key thing to see here though is that none of the results took more than a single frame to start rendering which is great news. One area I was surprised to find wasn’t quite as good was the panel uniformity. The lower right corner was considerably (although not visibly) dimmer than the brightest area in the centre. Like, 18% less light. The centre was at 408 nits, while the lower right was at just 335 nits! In fact, both the top and bottom edges were generally over 10% down from the centre. While I can’t say I noticed that in use, that’s less than ideal for sure.

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.
