Nope! 720x400 72hz was extremely common for games and apps. It's also why a lot of cheap Point of Sale LCD monitors around the turn of the millennium had 75Hz panels

Or if they were "high resolution" 800x600 56hz

Can you point to some source for that? I've never heard of a game using that resolution. The vast majority of them used the standard 320x200, either in CGA, EGA or VGA. The first two ran at 60Hz, VGA at 70Hz. A few games in the mid to late 90s started to use some non-standard tweaked VGA modes but by then Windows 95 started taking over gaming. You can check Wikipedia or Mobygames if you don't believe me.
