and what about contrast ratios, refresh rates, how many hdmi inputs
how does it display standard def (some lcds just really suck in this area)
I have a DLP Led & a LCD the dlp blows the LCD away with standard def
it actually looks HD Quality on the DLP one.
and of course how much will it cost. compared to this one or that one

Another point which is commonly overlooked but very important in my books is viewing angles. Does the TV have good viewing angles? Especially important if your buying an LCD.
