[Coco] Modern monitors that work on CoCo 3 and MM/1

[CoCo Demus]

I have an ASUS VG228GQ from October 2020 with a VGA port that accepts 15
Khz only if you invert the Coco Sync to a composite sync.

Good image upscaling the only downside is a wide monitor, there are no
aspect ratio settings on the menu for VGA input to the display gets
stretched.
