Current setup is basically an HDMI Matrix 4x2 switch ( Generic brand ) feeding 2 AVR's - a Denon and a Yamaha. It has 4 HDMI's in and 2 HDMI's out to feed two different devices separate streams. I have it setup like this so I can feed the MySKY, PS3 and BluRay into the livingroom setup or into the cinema setup ( or both at same time)
The Denon feeds the TV in one room ( a 6 year old Bravia KDL 55x4500) and the Yamaha feeds the projector in the adjacent room. Into the switch I had MySKy, PS3, Blu Ray and a WDTV Live...
Just replaced the WDTV with an intel i5 NUC. All working well on the monitor at my desktop PC when I set it up.
Once connected into my current setup that's where the issues started with the NUC and TV side of the equation. Black screen when I select NUC as the source through the matrix switch. All other sources work find - Sky, PS3 etc..
Some other facts.
1. The switch is of the type when you change input selection between devices, all the signals cut for about 3 seconds while it re-establishes relevant handshakes.
2. The switch won't allow you to select a source unless it detects a signal. So if the PS3 isn't powered on for example I won't be able to switch to that source until I flick it's power switch
3. IF I have the black screen and hard reset the NUC by holding down the power button, then immediately reboot it, the safe mode " your computer didn't shut down properly' start screen appears on the TV and all is well and very usable so it CAN actually handshake.
4. The NUC when plugged directly into the telly via HDMI works fine so it's either the switch or the Denon not liking it.
5. Have tried different cables and different ports on the switch with no change....Pretty sure that that hardware aspect is all good i.e not a faulty cable etc
6. It sometimes works and often doesn't which is making fault finding hard
I did notice that when the screen on the tv is blank and no windows deskop appears there is no onscreen GUI from the Denon AVR - basically the menus I can call up to play around with speaker size, inputs etc. These generally get overlaid on top of the video signal so at first it appeared to me the denon isn't connecting with the telly ?? It does on all the other sources however and the menus pop up when that other source appears on the screen.
The NUC does however appear to work perfectly with the Yamaha Amp and projector which is fed from the 2nd Matrix switch HDMI out. No issues with blank screens etc. It just works everytime I power it up.
From the above, any clues if this is NUC and the Matrix Switch, the switch and the Denon AVR or the Denon and the Sony Bravia TV ? Given the layout of the kit etc and most wires having been run through and along inside walls it's not the easiest to quickly swap stuff around. I'd have to do a pretty major unplug everything and start again to try a different amp etc.
Thanks for your thoughts. This doesn't seem just related to me having read most of google tonight...
