@Zac67

It was more than that as it showed up even on nonmoving images. Maybe it was a defect one...

All scan doublers / flicker fixers produce 'comb' artifacts at fast horizontally moving objects.
This is caused by both fields (usually) showing two different pictures spaced 1/50th second apart. Only professional scan doublers and modern digital TVs avoid this by interpolating between the frames - which might be more or less successful.

Amiga screens are (for the most part) non interlace and dont suffer from these artifacts.

The main cause of artifacts with the external scandoublers (including some in lower cost LCDTV's) is noise introduced due to analog (A2D) sampling of the RGB signals. The signals go from Digital->Analog->Digital->Analog->Digital sheesh!

Clip-on internal scandoublers and video slot scandoublers dont suffer from this as bad as they get the signals before the video DAC and so only go Digital->Analog->Digital

I guess the ultimate scandoubler would be internal to DVI where it would stay 100% in the digital domain.
