When I put my CRTs in storage (like 2018, so yes, I had them hanging around for like two years), I did so with the idea that I'd get a 4:3 1600x1200 LCD.
I got the LCD (Dell 2007FP S IPS). And to my surprise, it does the job well enough as a native 4:3 display. 800x600 and 480p content is very good.
I don't think I could ever give up the space for a CRT again, even a 19inch VGA unit just takes up too much room.
