Currently have a Sharp Aquos LC-26D40U hdtv manual says its 1366x768x3 dots Just got Veriozen fios (cheap package) and an xbox360... already bought the hd component cable for the 360 and have that hooked to the tv the set top box is a motorola HD QIP6200-2 The verizon guy set it up using 3 component cable set... This cable is not hd is it? Should I try to get a hdmi cable for the set-top-box to the tv? My belief from reading for 1 hour plus is that the set top box is downconverting it and the tv is converting it back? not positive though Also is their a way to really test and see the best picture possible? like a way to have it scroll through different settings and see which I like best?
