I have a Yamaha RX-V 663 and the 9300 ASUS motherboard (P5N7A-VM).
Attached to the AVR is TOSHIBA FULLHD Regza. The TV gets detected in NVidia Control Panel, the AVR overscans somewhat, but ok, everything works fine.
But if I change HDMI input on the AVR, and some time passes, the TV display is gone from the Control Panel. It detects it but does not add it automatically.
Same thing happens if I turn off the AVR of course. The PC goes around the clock, so it is irritating that the display does not get added automatically when I turn on the AVR. Specially since Nvidia driver does not remember the correct settings so I have to tune it again and again.
I realice this perhaps is related to that EDID does get transferred when it is off or uses another input. I know of the Gefen HDMI detective, which is ridicoulsly expensive.
Anyone know a workaround? It should be possible to fool the pc to think there is display there at all times, one should think. Is EDID stored in registry? If so one can write to registry at a certain intervall if drops out perhaps?
And also why does the avr overscan? Connect directly to the TV there is none. Is this EDID related? Fixable?
Hoping for for some constructive replies!
