I have been using an HDMI splitter for some time now - no name brand from the interwebs - its always been a little bit of a mission to get set-up when ever I install a new device (source or display) but once set-up it works flawlessly.

The problem is I have just had my projector returned after having its main board replaced by the manufacturer and cant seem to get the switcher going again.

I started with everything powered off, switched on the display, switched on my receiver, switched on my Apple TV (feeds through receiver) - picture displays on screen. Next I changed inputs on my receiver to my HTPC and the booted the HTPC - HTPC picture displays on screen.

Here is where it gets interesting - if I swap inputs back to the Apple TV, no display, going back to HTPC is the same, no display. 

Its like its setting everything up and handshaking but then losing it all when I change inputs. 

Anyone got any ideas on what to try next?

If I have to I can use my receiver as a splitter as it has two HDMI outs but the issue with that is it passes both displays to the input device so when I change display the HTPC has to go through the whole new monitor detection routine which results in the screen flashing a couple of times and being unusable for a minute or two. The standalone splitter just keeps the first display used in memory and uses that so the HTPC never sees a change.

Isn't the arrangement you are describing an HDMI splitter, rather than a switch?

If it's an HDCP re-authentication issue there's a good troubleshooting guide here...

Id say it will be your cheap splitter. Try buying or borrowing another splitter and see if you have the same issue.


I have had many issues with cheap HDMI equipment as they generally don't like the signal being interrupted, quite often with cheap equipment you end up losing signal or having a green/blue tint in the image.


I have seen the issue you describe with someone using a cheap HDMI matrix.

I had so many issues with splitters and got a HDMI + optical switch with remote. Works perfectly with the universal remote

I would usually agree but I have had it for 5 years and its been through a number of different sources/receivers and display devices with no issue until now.

Thanks, I'll have a look through and see if there is something I've missed.

sorted. the key was to switch my receiver off at the wall before plugging the cables in. so the steps were as per the link provided by mclean (in case anyone else has this issue).

 

Power-off all equipment (At the wall socket).
2. Ensure all Cables, Splitters, Switches, Extenders are connected within the HDMI Distribution Network.
3. Power on all Splitters, Switches, Extenders within HDMI Distribution Network.
4. Power on all displays and set to HDMI input from HDMI Distribution Network (Source device need to be able to contact display to retrieve EDID information)
5. Power on Sources / Players. Ensure that a path is open from source to display for HDCP handshake negotiation by selecting the proper input on HDMI Switches or HDMI switch/splitter combo's via the remote control (Sources negotiates HDCP Handshake via HDMI Network to displays which is set to HDMI input to respond to handshake).

Some displays will negotiate HDCP handshake / timing better if the source are already powered on and you may need to change points 3,4,5 above to 4,3,5 or 4,5,3 depending on your equipment.
