Question about AcerPower FH - P4 631 3 GHz (S6463624) PC Desktop
I have had this problem before and am not sure what causes this to happen. we have computers with dual video cards so the teachers can display there computer screens on tvs for the class to see. well i have had this happen a couple of times. when they are trying to display something that requires windows media player all you can see is the media player but the screen for the media player is black on the tv even though it is playing on the monitor just the way it is suppose to. what causes this? i went to the settings on the video card to make sure it was still set on clone but that didn't help. any ideas? thanks in advance for your help. ps i luv this site, you guys are so very helpful and fast to respond!!
Yep, hardware acceleration only applies to the primary output.
You can either use the video card's software to switch screen1 and 2 around (which puts your taskbar and everything on the external screen) OR
You could try going into media player's "advanced" preferences tab and look for video acceleration and hardware acceleration. Turn all of those off, and it might work by dragging the player to the external screen.
I usually put my laptop video card into "clone" mode, so both screens are identical... that works for me, and it's also easier for me to control or see what's going on because it's still infront of me.
Let us know!
