I just picked up a UGA-165 that I’d like to use to connect my Mac (10.6.7) to a projector (An older IBM C400). MacOS properly detects the native resolution of the projector and it shows up in the “Displays” pref pane, but the projector doesn’t detect the presence of a video signal.
No signal is detected whether I’m using DVI or VGA. I tried another C400 projector and even tried a USB2-VGA-165, all failed.
The C400 projector *does* detect and display a signal if I plug it in directly to the Mac. The UGA-165 also works properly if I plug it into an LCD monitor or a different kind of projector (a Panasonic AE-3000), so it looks like there’s a specific issue with this projector detecting a signal from a 165 chip.
Any suggestions? Is there any more information I can give you? Thanks!
