patrikk68: Yes, with aspect=true borders are back.
But I will rather play with borders than unnatural stretched screen.

I was firstly afraid that borders are sign of some bad setting.

Anyway, what's the difference between scaler and pixel shader?
As I understand it, Scaler scales by the exact "x" number. hq2x scaler scales exactly 2x, and the monitor/gpu/etc does the rest, while pixelshader scales directly to the requested resolution. Compare your screenshot and mine. Mine's got a lot less pixellation/jaggies, but it almost looks "abstract" because of the hq2x pixel shader's working so much.

pixelshaders will only work in the special builds and only with output=direct3d.
