Hi,

...First of all sorry for grammatical errors, I'm using an online translator...

So, I have an NUC7PJYH and have this problem :

When i shift from HDM1 (kodi) to HDM2 (sky) and return to HDM1(kodi) i lost the
signal.
To get back the signal I have to restart the system.

I tried any version of the kernel and also the drivers available but I always
get the same result: No signal.


Some info in attached files


I also tried the "possible" fix of Clinton Taylor :
"A simple msleep(50); at the end of intel_ddi_disable_transcoder_func() appears
to resolve the issue. This is also a W/A and not the final solution."

And 
"In intel_hdmi.c  mothod hdmi_12bpc_possible()add return false;"

But I had no luck</pre>
