We have in the office some laptops which work fine, as in:- they will show DVD on the Laptop screen and DVD on the Projector (or 2nd source) without a hitch.
And others, which will, show the DVD playing on the laptop but display a black image on the 2nd source, or, if you choose to output solely to the 2nd source, will work fine, but obviously you have no visuals on the primary (laptop) so for presenting etc this aint too good.
Is it something as serious as GFX Chips ability. I know mines an ATI Mobile 9100 and works flawlessly, but the one im working with at the minute which has issues is an Nvidia 5200 GO. I also know one other Nvidia Go system to have this issue.
(but in the back of my mind have a feeling one of oour users who may be nvidia has it wrking)
or is it down to codec's ?
On the Nvidia struggly one, ive just uninstalled all codecs and installed KLite... This still hasnt helped. But i understand it could still be codecs.
I installed WMP10 too, to see if that helped. No Joy...
anyone got anything to offer?
