Evening all,
Sorry if this should have gone to LUV-Main instead. I'm not sure how Linux related it will end up being.
I'm looking for a little direction on an issue with an Acer P1266 projector which won't work with PC devices plugged in using HDMI. My knowledge of HDMI and all of its standards and uses is very limited but I understand I should be able to plug in a PC and have it just work.
The issue is that the projector will just sit on HDMI without attempting to mode set when a computer is plugged in. I was under the impression that the HDMI port was just broken until fiddling with the HDMI caused it to set a mode once or twice. What it set was something unexpected like 480x360 48.36 hz @ 85 and after reading the available modes for HDMI in the projector manual I found this was not one of them.
Just to be sure - you plugged the projector into the PC before powering up the PC? Most motherboard based HDMI/DVI ports only operate if they find a display device on boot up. This includes laptops with "graphics cards". Normal graphic cards happily spit out VGA and DVI together.
