Recently decided to jump on the 3D bandwagon. I use my HTPC also as a desktop - and switch between using my monitor and the projector. I've been doing this now for over a decade, but NVidia is driving me crazy
- NVidia video card (GT 430) that replaced an older ATI card.
- Denon AVR-1611 HDMI 1.4a receiver
- the new Optoma HD-3300 projector
My LCD monitor is connected via DVI. HDMI goes to the Denon receiver. Denon's output goes to the Optoma projector.
When I use Dish as my source, Denon & Optoma work well. No problems.
But, I can't get the PC video output though the receiver to Optoma. I can directly connect Optoma to the PC and make it work.
Looks like, when I just connect the receiver to the PC (without connecting the PJ), NVidia sees it as a 1080i "display" and outputs 1080i - which Denon works with. But once I connect the PJ, NVidia sees it (though the receiver) as a 1080p display and outputs 1080p60 ! Receiver will not handle this (or it won't pass it to the PJ). So, no video on the PJ.
How do I control this behavior by NVidia card ?
There are some other issues too (like when I connect my monitor to NVidia card by VGA, it will only output XGA ! or as soon as I switch on the receover, the display is switched and I don't see anything on the monitor - nor on the PJ). But we can get to that later.
Oh, BTW, is there a way to setup hot keys to switch displays on NVidia ? When Vista came out, NVidia control panel wouldn't allow this forcing me to switch to ATI. Does NVidia support hot keys now ?!
