Showing music videos on big screen while singer sees graphics on his monitor

[nreel]

AS far as I know, Computers may ONLY have ONE Video Card.

I wonder if there is a way to continue what I am currently doing(toggling big screen between laptop screen and karaoke graphics) and keeping singers monitor to karaoke graphics after adding Hoster to the laptop? What dya think?

Therefore, NO.

With the SAME COMPUTER, you either use the Video Device to Display Graphics (from KMA/MP3G) from Hoster or a Video (MPEG/DVD) from Hoster or a Video via a different Program.

It is Impossible to make a SINGLE Video Device display both, at the same time, from the SAME Computer.

You, still, will need a second Computer...laptop or otherwise...and utilize a Video A/B Switch.
