Wierd, I've got my Windows 8.0 laptop hooked up to my 40" Samsung 1080p telly (bought in 2007) and it all looks good, even from ~3m away...and that's using just the VGA input (Dell didn't stretch to a DVI port on their cheapo Vostro 1720 range back in the day).
Well your eye sight is way better than mine. Metro apps are almost usable, the desktop is barely usable (I have to walk over to the set, and that's with the text size increased. I have a very small (not titchy) living room.
