i had a 32" LG LCD tv as a monitor for like a year ran resolution 1366x768 it looked so sharp its not even funny,my eyes did not heart at all, but some tv's are not like that. what you should do is take a laptop and a dvi r a vga wire with you to the store, and ask them to hook it up( just tell them if it works good you'll buy it tomorrow) that way you know exactly what you're buying. I'm getting this soon and it should work nice as a monitor since it has higher resolution which would allow me to sit closer.
I'm trying to get user opinions of these since that normally helps weed out the problematic ones and cuts out many options. I don't know what I'm looking for here when buying an HDTV for my PC.
