and I don't know anything about them so I need a lot of help I think. I don't know to much about TVs either but can I watch TV on my computer in HD or do you need to get something from your TV provider and will I be able to play my Xbox, PS2 etc. on it I think oyu have to get an external one for it thou but I don't know. I don't want to spend $200. So can you guide me from here?
