I think this might be a quirk of the Amiga and me not understanding some of the settings.

640×256 and 640×512 (interlaced) with 480i/576i passtr off both show up on screen as the exact same size, but the 512 hight does have more lines. but I get a lot of flicker in the interlaced mode and no option for scaling.

The squashed picture was when I let the TV handle the de-interlacing, which gave me a picture with no flickering but oddly proportioned.

the LCD screen reads as follows:

640×256:
AV1: RGBS 313p
15.62Khz 49.9Mhz

640x512i:
AV1: RGBS 625i
15.62Khz 50.00Mhz

My TV reports 576p @ 50Mhz for both.

All games run at the lower resolution and I’ve always used workbench at the lower res (as the monitor’s I’ve had hasn’t handled the interlaced mode well) so its not a big problem. I was wanting to try out different things on my new box and hi-res mode as always been something that I’ve wanted to see done well.
