Anyone wants to tell him about CRT's?

Now that will truly blow his mind, at least on this setup and older games.

Even the oldest and cheapest CRT monitor my family had was pretty pixel-accurate unless you were right at the edges. I was doing pixel art on it as a child and had no issues at all.

I don't think it really applies when we're talking about PC gaming. Consoles were blurry as hell on a huge interlaced low-res TV, but late-'90s PC games on a decent monitor had nice and crisp pixels on a CRT that weighed as much as a large dog. Especially when flat-glass trinitron CRTs and the like came out (yes spellcheck, that's a word), I don't think the end-user appearance on the screen was all that different from what we have now, other than obvious stuff like aspect ratio and incremental improvements to resolution and framerate. Maybe deeper blacks and lower latency on CRT.

The ability to shift resolutions natively was neat, though, I missed that in the pre-4K days.
