Not all gfx cards have autoscroll, but I concede it's "not useless" in that mode.

Select 320x200 or 240 mode and draw some differently colored lines in MSpaint or whatever, and if you look closely each pixel has a horizontal split in it. That signifies that the "320x200" pixel is actually 2x2 "640x400" pixels.

This is the same effect as hires+double in WinUAE @ 640x400, but in hardware.

You can also press the OSD menu button on the CRT. If it shows the same horizontal frequency for both "320x200" and 640x400 mode, it is the same mode. One has doubled pixels in it. Agree?
