Define half decent - to some lads on here that would be 28" 8k with proper colour calibration, to others like myself it's whatever black rectangle is the cheapest and I can look at porn on.
I have a few Asus VS248HR's - they're fine. Look decent enough and are about a hundred quid a pop, which is about my price point. You'd need to buy a usb-c to HDMI adaptor but that's about it. (They do have a VGA port but I think that limits your resolution somewhat) certainly good enough for office work.
