Usb to VGA Powerpoint Win XP
 
Hi.

I work in AV for a college and we have a bunch of classrooms that use some older software that only works in Windows XP (apparently). At any rate, they have these HP All-In-One computers that only have USB video outputs, so the IT department bought the DisplayLink USB to VGA adapters.

On our Windows 7 builds, we downloaded the latest driver and everything seems kosher.. but on the XP build, when we go full screen in powerpoint the video turns black, lags, or begins artifacting. Saw something like this with Hardware Acceleration in new versions of Firefox.

My question: Is there a DisplayLink driver that would allow a Windows XP computer to go full screen in PowerPoint? Would an older version of PowerPoint work? What should we do?

Thanks
-Dave

This is due to hardware acceleration and our software based drivers not getting the updates. This happens in PP2010, older versions of PowerPoint don't do hardware rendering.

You can work around this by lowering the hardware acceleration level of the primary screen to force PowerPoint to do software rendering. It should then also render correctly onto the DisplayLink screen.

Sorry, where is this done? In the control panel, display settings?
