Matanong ko lang... hindi ba maganda yung VGA (analog) output nung ATI na cards? I occasionally connect my Mac (NVidia yung video nya) to the LG Scarlet via VGA at 1920x1080/60Hz and I don't see any blurred text or any other PQ issues, in fact the text is so crisp and the colors pop brilliantly. I tried connecting by HDMI (through a chain of cables: miniDisplayPort -> DVI, then DVI -> HDMI, then HDMI cable to Scarlet), and I didn't see much difference (was so surprised).
So in some cases, probably depending on your video card's VGA output quality, connecting to the LG Scarlet via VGA is a viable option, if you wanna use the TV as your PC monitor. The catch is, as an HTPC monitor, it seems to me that it disables TruMotion 120Hz and Real Cinema 24p and all those video processing. But this is also true for the "PC Mode" of the other LCDs, right?
