I don't know who makes the biggest LCD TV but it might currently be Sharp's 37 incher. I saw it today in Yodobashi camera. I've personally never liked the plasma displays. I can see each pixel on a plasma display as there is a space between each one so for me it's like I'm looking through a wire screen. I was happy to see this LCD TV did not have that problem. To bad it's about $8K!

The display is 1366x768 if you are curious and yes, you can plug your PC into it if you want 😉
