We started with a "dead" laptop - one that my son had damaged the screen on. Our Samsung 43" TV has a VGA connector on it, and it was a lot easier to run an Ethernet cable to the entertainment center than anything else- I already had a BlueTooth wireless mouse and keyboard. I'd originally intended to switch in a computer with a DVI connector, but that never happened. Why? Because today there is a much much better way to do this ....
Don't even bother with a computer.
Samsung and Sony (perhaps others, but these I know) both make BlueRay players (the one we have cost about $149) that will play movies from your Netflix instant queue. (As well as Blockbuster, Pandora and YouTube). It looks better than it did off the computer, and is a whole lot less mess and messing about. Simply place what you want in your instant queue from a computer, then select it on the BluRay player to play it. I used a wired connection for ours, but Samsung has at least one model that also supports a wireless connection.
(One caveat - for some reason the Samsung BluRay player didn't work properly through my Netgear FVS318 router, even though the computer did. It would connect, but wasn't able to stream - or show the graphic of the "DVD case cover". No solution could be found, so I switched routers.)
Anyway, that's what I did - and it's the only way I'd do it again.
