I'm getting ready to finally upgrade from 1080p and I want to get a 4k monitor to replace my current 40 inch 1080p monitor, however I'm not sure what to get or from w hat seller. I've read that some of the monitors Tek Syndicate has reviewed got new revisions that aren't as good. I need it for gaming as well as general productivity, can anybody tell me what 40-45 inch korean 4k monitor I should buy? I don't need freesync because I use nvidia.
