yes there's 2 ways that i noe possilbe
one is if ur computer has the input itself (which i do)
or u can buy one of these things that let u watch tv on ur montior
(not sure wat it's called but my uncel had one
the way that thing would work is
you connect wire that u connect between the computer and moniter into that thing and get another one of those wire and connect it to the comp

btw u can problly get it for $20 to $50
