CHROMA SUBSAMPLING

Chroma sampling is not often discussed when purchasing a LCD display. The Blueray disk uses 4:2:0 which is a compromise due to limitations of H.264 and the space available with a dual layer BD disk.

A PC generally uses 4:4:4 which HDMI cannot handle above 1920×1080 while DisplayPort can handle at 2560×1440 and 3820×2160. Revisions to the respective standards have improved the bandwidth but there are still issues with high dynamic range displays.

The LG 27UL500 supports HDR in Windows 10 and it can handle even 4:4:4 chroma sampling with DisplayPort. This is the reason the picture quality is superior.

The image above shows 4:4:4 chroma with red/yellow/blue/green/magenta/white/light blue/grey/blue on red/red on blue. This image will not look correct on most lower cost televisions which still largely use 4:2:0 chrominance.

The color quality of IPS cannot be disputed when it comes to 4:4:4 vs 4:2:0. The LG 27UL500 is capable of handling the best that a PC can deliver.

MOUSE VISIBILITY

The very high DPI of the LG 27UL500 maybe tricky to find the mouse with the default settings. Go into the Control Panel and Ease of Use and select the mouse. Select the inverting which will change the mouse from back to white as needed making it far easier to use.

STEAM

Less than 1% of Steam users have a 3840×2160 or better LCD to play games on. The reason is simple, video cards are not able to handle 4 times the pixels of the HDTV display.
