Oh god, the thread derailed pretty fast. OP propably meant the Intel GPU driver notification which pops up when the game resolution is different from Native resolution. EG. when a DOSBOX game start up fullscreen at 800x600 or whatever, the the godforsaken retarded popup comes up and fucks everything up (at least it ducks up some games).

Do you use drivers from ATi/AMD; Nvidia; Intel pages or shitty ones which come from Microsoft/Windows Update?
If you use old drivers, try first updating them. I remember that some Intel GPU drivers didn't have OpenGL support when you used the ones from WU.

Maybe try updating directx aswell (only 9 needs to be updated, newer ones get automatically updated by Windows Update): https://www.microsoft.com/en-us/download/details.aspx?id=8109

I think so too, at least for games and pc monitors.

Definitely. That's about the time I noticed widescreens starting to take over, although I recall 1280x1024 being popular at the time. Resolution kept going up and up back then. Around 2005 or so there were a handful of people I knew that even had 1920x1200 monitors. Well, 1920xWhatever was a decent place for it to settle down at last.

Then again, who am I to talk about resolution, I'm just looking to get a nice high-resolution Amiga monitor so I won't have to use that A520 adapter and be content with a composite signal from my shiny Amiga 500. :-P

That damn composite/RF adapter is larger than an entire computer nowadays (Raspberry Pi is just a bit smaller, not to mention the RPi Zero or the VoCore).

Assuming we're talking about "RIVEN: THE SEQUEL TO MYST", I understand it's locked at 640x480.

Most old games (i.e. pre XBox 360 HD) are happiest in 4:3 - WXGA never really took off for gaming widescreen and it died when 1080 monitors came along for the PC as well.
