Hey guys.
I also don't have any of the addictional software installed.
Though everything worked fine for quite some time now, something very strange happend today. I tried to connect my projector to dell and the display turned white and there was nothing left to do, but reset it with power button. I tried again and it was the same. I started to think about what can be different and the only thing that crossed my mind was - cable. So I swaped directions and it worked. I couldn't bealived it couse the connectors on both sides looks as twins. I tried to swap it again, and the screen was white again...
Best regards
