I got mine like a month ago and it really is a good investment if your eyes are hurting, I use it for coding and it takes time to get used to it, for things like the ones you mentioned, levels of constrast are not so good at max speed and the resolution gets worse in video mode so I use normal mode at max speed (7), sometimes when I get bored I set the speed to 1 just to see how the image quality improves xD. I bought a vesa stand but since I use it at home and in the office it just not practical to use that setup, instead I ended up using an old stand I got for my notebook and never used until now. https://www.amazon.com/gp/product/B081YXWDTQ
