That's what I'm asking. When the monitor is live, it can draw a complete screen ~30+ times every second, so why does it take more than 1/30th of a second to start from nothing? Then, I speculated that the only reason I could think of was if the graphics card doesn't actually send every pixel every frame, and there's no way for the monitor to request a full refresh.

Monitors don’t request anything. The monitor has to do a basic handshaking/negotiation before it even knows what sort of video stream to expect

Ah. And we couldn't stick... What, 4 ints of metadata in the video steam (width, height, depth, frame rate)? Not like we don't have the bandwidth. I can believe that, but it's disappointing that nobody bothered.

Historically speaking bad things happen when you hand a display something it can’t handle - including not being able to see the settings dialog to fix it.
