A few of the things I have had to do in order to get a workable version of HDR (also known as high dynamic range), the new-ish display technology that significantly ramps up brightness, darkness and vibrancy, on my PC (not including the acquisition of a fancy monitor):
– Try four different display cables
– Adjust as many as seven different brightness/contrast/colour etc shaders per game. (I have spent long, unhappy hours doing this to date)
– Manually turn on HDR on the monitor, manually turn HDR on in Windows then manually turn on HDR in the game settings. Or sometimes HDR off in Windows but on in the game then alt-tab back to Windows and turn HDR on, and off, and on, and off. Or sometimes alt-tab and alt-tab and alt-tab and alt-tab and alt-tab until HDR suddenly, randomly kicks in. When I exit the game, I have to manually turn it all back off again or Windows is unusable.
– Install an unfinished preview build of Windows 10 whose HDR isn’t totally broken on Nvidia cards.
– Almost completely lose my sense of whether anything is actually different after all of this.
