Opinions?: HDMI 4x2 multiplexer + 1x2 splitter or 4x4 multiplexer or new Receiver?

post #1 of 2
Thread Starter 
I am having trouble with my 4x2 multiplexer switching signals when my 1x2 splitter is hooked up to one of the outputs.

I currently have a 4x2 HDMI multiplexer similar to this:

and a 1x2 splitter coming off one of the outputs of the multiplexer:

My setup is the following:

Multiplexer Inputs:
DVR
PS3
XBOX 360
Computer

Multiplexer Outputs:
1x2 splitter
Kitchen TV (in adjacent room)

1x2 splitter:
Input: Output from Multiplexer
Outputs: TV, Projector

My projector screen drops in front of my TV so I would never need to output a different signal on each. My kitchen is in another room so it would be nice to have the flexibility to output something different than what is shown on my tv/projector.

The problem I am having right now is that if I have both TVs on and turn off my kitchen TV, the 4x2 multiplexer won't switch to the 1x2 splitter and the display on the TV turns off. This requires me turning off the multiplexer manually. When it reboots, the TV picks up the signal again.

One possible solution is to switch to a single product like a 4x4 multiplexer:

But my AV Receiver is also old so I am due for an upgrade, possibly one with HDMI switching.

Anyone have any suggestions? Is there a fix to my problem? Or should I go with a new 4x4 multiplexer or new Receiver?

Thanks!

Check the kitchen TV's settings and disable anything like "HDMI control" or "AnyNet" or anything else like that. Does this happen on all of the sources, or only certain ones? It sounds like the source may be changing its output when one of the displays drops off, and someone's getting confused in the process.

Does the behavior change if the HDMI splitter is removed from the mix, with just the two TVs attached? (I doubt it)

If you upgrade your AVR, you will almost certainly get HDMI switching - very hard to buy one today that doesn't have it.

I don't think your particular problem will be solved with a 4x4 matrix - I think this is an interaction between the displays and probably the DVR. Do some experiments to see what works and what doesn't...
