Im still on 1080p.
I had the option of going 4K or high refresh rate for my last monitor and I decided for High refresh rate.
I dont know if thats the "better" option but I do think that because 4K is very demanding in gaming its still too small of a market for prices to drop significantly.
"Let’s start with Dynamic HDR, a rendering technique in which high dynamic range information is sent to the TV throughout a video—scene by scene, or even frame by frame—and not just at the beginning, as HDR-10 handles it. This allows for finer control of brightness and color levels. Dolby Vision delivers Dynamic HDR via the current HDMI 2.0a spec."
Amusing repartee, but, this HDMI upgrade is long overdue. For some reason, DisplayPort seems to have suffered from arrested development a couple of years ago, and is now being neglected in favor of HDMI, so, higher bandwidth on HDMI is very important. Gamers want faster updates (e.g. 120Hz), and, non-gamers want both more physical (e.g. 4K/5K) and color (10/12 bpc) resolution. Connections should exist that support all three at the same time, yet, high-end monitors like the Dell UP3017Q are limited to DP 1.2 or HDMI 1.4. I don't get it. The monitor display and the GPU output capabilities should be the limiting factors, not the connection between them.
