I got a full HD (vertical, IPS), 2k (IPS) and a 4k (TN) screen on my desk. All have VGA. I also have a 4k tv on my wall. It also has VGA.

  You have 4K equipment with a VGA port. But does it actually do 4K when using VGA or does it just downscale? I haven't ever seen any VGA cable which can go above 2048×1536, and that's also the maximum wiki mentions: https://en.wikipedia.org/wiki/VGA_connector#Cable_quality https://en.wikipedia.org/wiki/VGA_connector#Cable_quality

    it upscales and its refresh rate is quite limited (i think to 25fps). we're talking about the presence of the connector, which let people actually use these screens - even when its not with the full resolution

      Ah, so it 'pays' with a low refresh rate. That makes sense. That said, my point was that 4K computer monitors are rare (despite some communities of enthusiasts), and nearly everything currently in use has a VGA port.

    When I set my mom up, in 2003 or so, I gave her one of mine 21" Integraph monitors. I was a bit jealous when I realized her computer was able to do accelerated 24 bpp 2048×1536 on that gorgeous (and back-breaking) screen. My laptop at the time could drive on external screen at 1024x768 and that was it. :-(

    VGA is an analog signal, so there is no theoretical limit, and the degradation is graceful --- edges of individual pixels will start looking blurry as you get closer to the physical limitations, but a recognisable image continues to appear.
