JTL Maybe LED is not the reason to make eyes dry and uncomfortable. A low end graphics card and a low end monitor, maybe they are the culprit.
I mean graphics cards with bad dithering algorithm and monitors with 6-bit LCD panel. When they come across, then something bad for eyes happens. You remember that intel graphics driver codes? He forces displays with 6-bit panel to use that bad dithering algorithm. I don't understand it, if I am the developer, I would rather leave it blank for 6-bit panel to use the original even only 260K colors.
