?I have few monitors from different brands and with different cables:
- micro hdmi > dvi
- micro hdmi > hdmi > dvi
- micro hdmi > dp
i found out that there is no problem with cable.
Problem is definitely on the side of Parallella's micro hdmi output
I have tested different cables and cable-adapter combinations with different monitors and different sources (Parallella, Rpi, HD Tuner ...)
I found a that only with Parallella I never got same monitors to work (= no signal or display in sleep mode)
I checked Parallella's micro hdmi output and found out that only difference could be in Pin 2 (RES) ... left open without any signal.
If all other contacts at micro hdmi are connected well then Pin 2 (RES) is the only difference.
Note: Parallella booted and run correctly all the time. Problem with "no hdmi display" is present independent from turning on order of monitor and Parallella.
I hope this will help someone from authors to check basic schemas and let us know what to do.
Next to hdmi problem I have also problems with usb port. Sometimes keyboard is not recognized. Mostly Apple's alu usb one.
I noticed that always when Vcc falls bellow 4.82V usb remains dead. But problem with Apple's keyboard exists also when Vcc is 5V!
(I prefer Apple's alu usb keyboard because of built-in hub!)
