My computer wont detect HDMI projector display!?

by 1010dame / November 17, 2010 10:50 PM PST

I'm running windows 7. My computer does not detect my HMDI projector.
The projector works fine connected to a DVD player with the same HDMI cable and my LCD TV works fine connected to the computer as a 2nd display. Again, with the same HDMI cable. Hence, I don't believe the physical connection (HDMI port/HDMI cable) is source of the problem.
The computer simply will not detect the projector as a display device....
I'm totally baffled. Please help.

Go into your PC's display settings

That's how you start to troubleshoot such issues.

I suggest you post this in the PC help forum instead since it's likely more of an issue with Windows 7 and/or your software driver/video card settings.

Thanks Pepe. I've updated my video drivers and gone into my display settings and tried to "force detect" the projector to no avail. Funny thing is that windows 7 did find the projector for a while and then it just disappeared.
