I just got a new Samsung HDTV 19 inch LN-S1952W model I plugged in my cable box but the picture was horrible!!! I then plugged in my 360 and That had horrible picture too!!! and sadly it just so happened that my computer monitor was busted after it fell...so i plugged it in...and the picture for the computer was fine... is there something wrong with this tv? my cable and 360 has such bad picture..while my pc has perfect picture or am i doing something wrong?
A regular cable box will give you a bad picture. You will need to return the box to your cable company and exchange for a High definition one. Only the channels that come in hd will be clear. If your cable company does not provide hd channels, then you're out of luck.
