I have a kind of strange setup. Laptop using monitor out to Onkyo 609 receiver PC in. All inputs on the receiver oput throught the hdmi to the wireless hdmi on my Epson 3010. When I switch to PC on the receiver I get the desktop duplicated on the projector just fine. I need to use it in an extended desktop setup though. I've used the same laptop for the same kind of extended setup on a normal LCD without issue. When I try it with my new setup I get just a purple screen out of the projector for the extended portion. No matter what settings I've tried I can't get it to work. Does anyone have an idea?
