I've been running a Sumsung 1080p for a few years now and have recently upgraded to an RTX 2070S graphics card. Of course I now need to upgrade the display, I initially opted for an iiyama 31.5" 1440p (£240) and checked it out, graphics were stunning except of this dodgy vertical banding, so I've sent that back. Now I am in a dilemma, 4K monitors I have noticed nowadays can be quite cheap, my budget of £400 will get me this, but I am struggling with the fact I might not be happy again... I just want my GFX to shine, I know it's probably a tall order for 400 quid and 30" but there are so many variables with screen response times, screen types etc. I need to ask. Is there a dogs bollocks monitor out there where I should just forget the rest and buy.
