Because it may have downconverted to S-Video. If you feed a RGB Signal into a TV and it allows adjustment of brightness and color you can be sure it's downconverted to component or S-Video. After that you need to upconvert it back to RGBHV.
IMHO 50 or 100Hz has nothing to do with it. |
Agreed Reiner, hence my Faroudja example of how even the high end use these common techniques. However there is a belief that they are using a 'purist' videophile approach. i.e. RGB going straight to the RGB guns. The reality (for all tvs?) is much different and the reason I wanted to 'raise' the topic.
Visual artifacts are a fault of the poor quality of tv internals and is the reason why I describe all tvs as flawed. Proper scaling / de-interlacing to a projector / plasma easily shows all the faults. I know of NO tv that does an acceptable job here.
