I have a Samsung 40" LCD HDTV (Model Number - LN-S4041D) and I've noticed that the HD stuff LOOKS GREAT but the SD stuff (especially) over the HDMI cable looks horrible. Just horrible with tons of noise every where and those "artifacts" around every edge that REALLY REALLY stick out and lines down the TV like every inch its weird.
Ive tryed Component Cables, S-Video, AV, and coax, while the component showed the same result as my HDMI the other 3 (s-video, av and coax) did a much better job but it was still not very good at all. I know it can be better because I've seen better on it and I've seen other SAMSUNGS (at bars) with MUCH MUCH MUCH MUCH better SD PQ (and yes they were LCDs and had cable and not satellite). So I really dont know whats wrong.
My cable STB is Motorola DCT3412 HD capable and I have HD on it. I've tried changing the settings on the box with its "4:3" overide setting to either "480i (shows it in 480i) 480p (upconverts to 480p which by the way makes the component and HDMI looks ALOT WORSE) Stretch (Stretches it to fit a 16:9 TV, still not good) and OFF (Shows it in 4:3 also no good) So its just horrible picture all over.
I dont thinks its my cables or my TV and I'm suspecting my house wiring (which is RG59 and NOT RG6, which we are replacing with RG6 in a few days), or my Cable Box.
PLEASE ANY HELP WOULD BE A LIFE SAVER I'VE BEEN TRYING TO GET THIS PROBLEM FIXED FOREVER!!!!!!!
