Hello from a new member.

I have a question.... Please excuse if any of my terminology is wrong.

I have a non-HD Sharp CRT TV with RCA, S-Video & coax inputs.

But I mostly watch a small circa 1980s TV that's about the size of my
monitor, because it fits on a shelf near my PC. (You see, almost all
my TV watching is either working in the kitchen, lying down, or at the
PC. I never just sit down to watch TV.)

I recently got an adapter for the digital video output on my PC that
allows me to use a 2nd monitor. So I have a small flatscreen as
monitor 1 and an old 15" VGA monitor set for low res as monitor 2. (It
works, but it's too dark to use hi-res or to watch TV.)

Following is what I want to do. Is it do-able -- and how?

I want to add another standard monitor output, so I can send online TV
shows to my good TV and use both monitors for work.

Is a video card all I need?

If so, what do you recommend? (Price is important.)

Would that be with RCA, S-Video, or coax outputs?

Thanks....
