The amiga screen fits quite nicely on a 1080p TV. Not all games will fill the screen vertically of course (same as on a real Amiga) but the "automatic center" option can be quite nice in these cases.
Scanlines & bilinear can still be turned on if that's your thing
This doesn't work for me on my 37" HD-Ready TV with a 1280x720 resolution. The zoom was too big and the D3D scanlines caused garbage. Anyway, i've changed
which is a 1.43/2.86 zoom and it looks pretty nice now. No scaling artefacts (ugly lines) anymore, just a little bit of noise which can you can soften with the bilinear filter.
Edti: Forget it. Now i know (on my PC!) what causes this annoying vertical/horizontal lines. It's a combination of scaling and D3D Scanlines/PNG overlay Scanlines. Without scanlines (but scaling enabled) it looks like the mentioned image noise.
