3 times now I have bought some new kit (e.g. tv, pvr etc) and when first switched on and checking it out, I find that RGB picture quality is very significantly poor! Then after a few hours or the next day, it is perfect! This seems more than just allowing the item to acclimatise! Once "burnt-in" the problem does not reoccur, even if the device is switched off for a long time and back on again. I have never seen mention of this before and am curious if others know of this. I use quality cables and try alternatives. I can well imagine people returning kit thinking it is faulty/poor quality. I almost have. Comments welcome!
