My setup is as follows:
Windows 8.1 Intel HD Graphics 4600 video bios 2170 driver 10.18.10.3412 (tried several drivers)
I have a ASUS H87I-PLUS motherboard with a Intel Core i7-4770S (HD4600)
The DVI port is connected to my ASUS VN248H monitor.
The HDMI port is connected to a Yamaha RX-V375 reciever and then to a BenQ W1070 Projector
The DVI/Asus monitor is set as primary display.
I have a couple of issues, but his is the biggest one:
If I turn off either the Benq or the Yamaha (HDMI), my DVI port with Asus monitor also goes blank, leaving me without display.
I've tried swapping cables (dvi/hdmi connections) but it makes no difference. If I remove the Yamaha reciever the issue does not occur.
(Also this is a windows driver issue, does not happen on linux, also does not happen with basic windows display drivers. But I need those intel drivers for HW and dual display options.)
Obviously the reciever is sending some off codes that makes the graphics card shut down.
Intel refuse to accept it as a issue, because it does not happen when connected directly to projector, only when reciever is connected.
All suggestions are welcome !!
