I chose my monitor very specifically for low latency, good color reproduction and "high" (as in the screen is higher than 16:9) aspect ratio - in about 2012! and I'm still quite happy with it. 4K is incoming, but only if it's better in all criteria, which became available fairly recently.

A lot of people still seem to buy their monitors without considering latency, which majorly sucks. It feels like the years between power supply efficiency making a difference and the introduction of 80+ efficiency standards.
