No picture on TV (1 Viewer)

[HakanThn]

When the PC is running before a switch on the TV, I often can't get any picture on the TV. If I turn on my AVR + TV first and then awake the PC there is no problems. But when the PC wakes up for a recording, and I later switch on AVR + TV to watch I often have no picture.

I have done a lot of testing, and the problem seems to be random. I guess that the PC / AVR / TV connection doesn't always succeed, maybe a HDMI HDCP problem? It happens most often when a recording is running, but I can't exclusively connect it with MediaPortal.

By remote controlling the HTPC through teamviewer I can see in Catalyst Control Center that there is no screen detected. Pressing "detect screens" doesn´t help. If a put the PC asleep, and wake it up again (with AVR and TV on) everything works fine - but not a good solution when a recording is running...

My system specs is in my profile.

Appreciate all ideas, this problem is killing the WAF

I found a ltot of useful information there.
I have now tried the HDMIon.exe and also devcon rescan mentioned in the thread, but neither work.
Now I´ve ordered a "Gefen HDMI detective plus", I hope it will help.
