People think I'm mad when I point out that old CRT computer monitors looked great at any supported resolution. 1024x768, 800x600, and so on, it always looked sharp. Not like now when playing below native res makes the image a smeary mess. TVs were much the same. Playing a SNES on a TV looked good, but playing them on a modern TV looks messy and basically unplayable.
Another peeve of mine is people seem to greatly underestimate their quality. Maybe I'm just nostalgic, but I remember the image on a CRT was slightly more fuzzy than a HD display, but most filters make it seem that the screen had inch thick black bars under every pixel, projected onto a fishbowl, and viewed through a gallon of vaseline.
