Live View on Television or monitor

I am currently shooting in my studio (mainly portraits) and want to be able to view larger images while shooting. It makes life a little easier if one has a larger image with which to make judgements. Does anyone know of a monitor that will work with the pentax video lead (live view) straight from the camera to the monitor, or do I need to buy a flat screen tv? Cheers all - happy shooting.

The video output works fine with digital projectors, so it should work fine with a monitor or a TV with a suitable input.

I use this to demonstate the menu systems to a group.
