I have a 40" Samsung LCD TV (its HD ready not full HD).
I have connected it to my computer via an HDMI to DVI cable attached to a 8600 GT video card.
I can see a clone of my monitor on the TV but the resolution is just too small. If I sit about 8 feet away, I cannot read anything. 8 feet is normal viewing distance. The size is is proper, meaning aspect ratio is no unbalanced but everything is too small.
If i reduce the resolution, things get better but I dont get the full screen, I have to scroll around the screen.
