I have no idea what makes chrisseaton so passionate and adamant that CRTs commonly had resolutions higher than common LCD panels today but I had basically this exact same argument several days ago. I actually remembered it because they wrote almost the same comment word for word. For some reason they are convinced that all old CRTs were commonly 2k and 4K resolutions and the existence of cheap 4k LCD panels doesn’t excuse the fact that it’s still possible to buy a 1080p screen (which is I guess a bad thing?)
Some people have unusual passions I guess.
