I have a problem and am looking for a solution. This is probably going to be long winded. Sorry.
Bought a new ivy bridge mobo and processor
z77 mobo intel 3570k processor.
So that means HD 4000 graphics
Now I find out that the geniuses at Intel can't, or more likely won't write hd4000 drivers which will communicate with a Denon receiver, which is what I have (of course).
With older chipsets, people could just do an EDID override and all was good.
The drivers in my computer will not even acknowledge the existence of my receiver/projector.
For example, if I try and force detection, I see some "no monitor detected" type of message.
If I run MonInfo, an executable which reads EDID info from a monitor, it reports just fine. So it isn't a cable issue. Linux can also extend the display onto the computer, and my old nvidia card had no problem.
If I remove the receiver from the loop, the computer will detect the projector just fine.
Now, the projector is an optoma hd81 which includes a separate box for doing switching and scaling. That unit has the following hdmi connectors
3 switchable inputs
1 output which would normally go to your receiver.
1 input from the receiver to the scaler
1 output from the scaler to the projector.
So the chain if you are using the switcher would be
source (bd/computer/satellite) -> switcher -> receiver -> (back to) scaler -> projector
but you don't need to use the switcher if your receiver can switch inputs (which they can), so the NORMAL way to hook up is to bypass the switcher and do
source (bd/computer/satellite) -> receiver -> scaler -> projector
What I'm hoping I can do is
computer->splitter--+-> receiver -> switcher (input 1) -> scaler -> projector
................................+->switcher(input 2)-> scaler -> projector
So that for bd/satellite, I use input 1: The splitter never enters the equation. Receiver splits out and plays audio, and passes video on to the switcher/scaler/projector.
For computer I use input 2: Splitter passes audio and video to receiver; receiver plays audio from the computer, video just gets thrown. Splitter also passed video and audio to switcher; switcher passes video to scaler, audio gets thrown away.
What I don't know is how those kinds of passive splitters are going to handle the handshaking that goes on. You now have 2 devices, the receiver and the switcher trying to communicate with the computer. Both will tell it they can play video (since the receiver thinks it will be passing it along). I really don't know if the switcher will tell the computer it can play audio when a receiver is not hooked up.
Now from the looks of it, some people have 2 tv's hooked up and they don't appear to cause communication problems. Other people can't get it to work.
Passive or powered: in either case can both tell the computer what they are capable of doing and work? In my case is one device going to say "I can't play video" and the other say "I can't play audio" and I get no output? Is Intel's second rate driver still going to see a "denon" on the wire somewhere and just send out nothing?
The computer is not going to be used for material requiring hdcp, but of course everything is capable of using it.
Will a powered splitter be any better?
Thanks
