Laptop to Plasma - Get desktop but no video image? Help please

[shadow4509]

Hi,

I' geussing that this is the best place to post this, so i hope someone can help.

I have connected my laptop to my plasma, everything is being displayed correctly such as the desktop or any applications i open but if i try to play a video then all i get is a black screen where the video should be playing. The video is being displayed and played correctly on the laptop screen but nothing on the tv screen. I have tried multiple players but still nothing.

Can anyone tell me where i'm going wrong.

Thanks

Probably not the correct answer but should work - go into the advanced display properties settings and in one of the tabs (usually troubleshoot) you should have a hardware acceleration slider - if you move that to None then the video should display on the TV fine...

I think the issue is with the video overlay which is dealt with in a different way than the desktop and so why may not display on your TV...

My fix basically tells the system to reproduce the video in the same way as the desktop which will mean lower performance of the video but should still play fine...

EDIT: Proper fix -

Declare the TV as the primary display and it will work fine - the laptop will become the secondary display and will stop playing the video but the video overlay will work then on the TV. Basically you cant display video overlay over more than 1 display...

Many newer graphics cards can support more than one monitor and/or a TV screen as output device. Typically one of these output devices has to be declared the "primary" device, and only the primary device can display hardware overlays. There are exceptions: Intel writes in the FAQ for their Embedded Graphics Drivers that the overlay can be attached to either one of the displays but not both, and some newer Matrox graphics card support overlay on both displays (e.g. Parhelia Series).

Both hardware and driver support is required; some graphics cards may support overlay on the second display while their drivers may not yet support it.

A common complaint is that DVD movies are displayed properly on a laptop screen but don't display on a TV connected to the laptop; in these cases it may be possible to designate the TV as the primary display. Sometimes, the use of hardware overlays may have to be disabled in the media player. However, some graphics cards have the option to completely redirect hardware overlay to the TV screen. In this case, starting a DVD player on the main screen with overlay enabled would result in video being displayed on the attached TV screen.
