My son wants to get a 38" +/- TV for his office. The TV will hook up to cable but he also wants to be able to hook up to his office computer as a second monitor, from time to time. (For presentations)

Assume that his current OS is XP Pro and video out is VGA.

Any suggestions will be appreciated. I know nothing about using a TV as a monitor.It depends on the model of TV, but most new TVs have DVI, VGA or HDMI inputs. Adapters can be found if the TV doesn't accept VGA inputs.
I know that's not too HELPFUL, but it's perhaps a start.
Remember that most TVs are LOW resolution too, so the display will likely look very blocky.Calum - Thanks.

Is it as simple as connecting the TV to the video card with the right adapter. Will a low end video card be able to 'power' a 38" display?It should be that simple, although the TV may NEED to be switched to the correct input using some button on the remote.
As for the card powering it, it's about the resolution, not the size. As the TV will probably be a lwoer resolution than a normal monitor, the card should have no trouble.Thanks You're welcome, glad to have helped.
