See both TV and computer screen at SAME time?

A friend of mine has the NVIDIA GeForce 2 and he can switch from TV to his
CPU monitor. He likes to be able to see both the TV and the monitor and the
same time. This is NOT TV program, but the output from his computer to the
large screen TV. In other words, he likes to see the SAME output of his
program under Windows ME on his computer screen and his TV.

How does he do that?

go to the NVidia control panel (display properties - settings - advance -
GeForce...) there you'll find a label called NView.
set it to Clone and there you go (but if you want an exact cloned display,
you'll have to settle for 800x600 or lower - ATI doesn't has this limit but
otherwise they suck).
notice that it'll have an impact on performance (FPS will drop about half or
so)
