On: A simple way to scale pixel art games

Is that true? Was there something to the technology that was harder on the eyes?

Low refresh rates. 50Hz for European TV (PAL), 60Hz for American (NTSC).

On an LCD, each pixel lights up and illuminates constantly without flicker. On a CRT, an unrefreshed image immediately fades away.

For desktop computing, the minimum ergonomic standard refresh rate was usually 70Hz. Even that was an eye strain over prolonged usage. I remember using 85Hz on my 1990s Eizo CRT.

So the flickering. Okay :)

Because I remember that, the bloodshot eyes after too long a night of gaming. Just hadn't realised it was because of the screen, partly at least, given that explanation.

The culmination of that was the Amiga's high resolution mode (640x400/480) which was interlaced, so only had 25/30 Hz!
