My first post. Ive been lurking for years but this answer's not here yet so Ive had to get involved! Ive made the mistake of itching my upgraditus, namely Dscaler 4.1.8 to 4.1.11. Id been feeding my Pio 433MXE1 via DVI, at 60Hz with good results on 4.1.8. The blacks were deep and white was really pushed. Now Im getting slicing or ripples down the screen when an image pans sideways (most notably on PAL video, read BBC1 type programmes). What causes this? can it be fixed?
