Many high-end late-era CRTs can do 1600×1200 or above at 60Hz or more while also being able to do 800×600 at esports-friendly refresh rates of 100Hz or above, all on a screen with an area which is still good by today's standards and with very low latency. You can now get a flat-panel monitor which does both a higher resolution and a higher refresh rate (and at the same time) but that basically wasn't true until a couple of years ago: and you'll pay quite a lot for that high-end gaming screen, and it still won't do 4K.
