First off, I use Directv. I have a samsung dvr too lazy to get the exact model. My tv, while not fantastic isn't crap (30 inch HDTV sony its not a plasma, or lcd just regular) now to the problem at hand. It's an odd picture quality issue, everything except blacks looks great. The blacks have like a fuzzy blocky look to them. Signal quality is great (94 stable) the actual cable is good quality cable, its 75 foot so i don't think the cable is the issue. For whats its worth, I've tried using a wall plate and not using a wall plate and i get the same results.
Is it possible that the signal is too strong? What are the symptoms of to strong a signal? And lastly, is there an easy way to make the signal crappier to see if it makes a difference? I've got some cable splitters but I don't think that it will degrade the signal enough.
Thanks in advance
