I recently read a MS article on 2 monitors & the benifit of them.
I purchased a Samsung Syncmaster model No. T200HD Monitor.
It has inputs for ANT-IN, PC, SCART, Componant, DVI-D & HDMI.
With the remote control provided, I can switch between use as 2nd monitor, cable TV, 2nd computer monitor or CCTV security camera.
The source list by pressing "source" on the remote is as follows;
TV, EXT., DVI, Component, HDMI1 & HDMI2
I think it is the greatest monitor ever!!
