you should list your budget and how many + what type of inputs you need. if you are just connecting it to your pc this is most likely 1 hdmi.
keep in mind that lcd televisions have pixels arranged in a different way to display shapes and lcd monitors (for computers) have pixels arranged to display text. text will appear more blurry on a television.
that said, it all depends on your budget. I buy sony products myself as I know there are parts available when it runs out of warranty. none of the other companies stock parts for repair so you might get hosed once the warranty is up.
if you aren't on a very tight budget a things in the market right now that are rather nice are:
-led backlit... but the screen is divided into hundreds of "squares" so you get backlighting that changes as your video feed does. this means that there can be a greater contrast between blacks and whites on screen. this also means that blacks can potentially be darker. i think samsung developed this but you would have to check.
-thin bezel designs. i happened upon one while in best buy recently.. the television had a very thing metallic bezel (maybe 1/4") with 1/2" or so clear plastic around this. the effect made it look almost borderless and like a window. very neat.
