Hey all,
I was comparing these 2 monitors and deciding which one to buy, the asus is 1300 euros while the Gigabyte is 900.
At first I was really happy with the MO32U24 as it allowed me to save 400 euros since I don't really care about DP2.1 or usbc power... so I thought I will be saving money on feature I don't need anyways, but when I compared them more https://www.displayspecifications.com/en/comparison/9a21348f2f I found that Gigabyte MO32U24 is missing HDR10 and dolby vision, now i know dolby vision is not needed for games (at least for pc gaming) but missing HDR10 is really holding me back.
So my questions are, what is HDR10 ? what difference does it make and is it worth the price difference in this case ?
