Unfortunately, the disappointment was very great:
despite the many resolutions and other settings I could elicit the part not stable. The complete picture content trembled greatly and was, in addition to the many RotGrünBlau error stripes, almost colorless.
In order to eliminate the age-old C64 as a dirty source, I tried the whole thing with a video recorder (S-Video). But also so that the image was not substantially better.
Clearly, one can not expect miracles for the price, but what was on offer here, to me is definitely not enough. Become part send as soon as possible back.
