Turning my Projector/reciever off (hdmi) simultaneously turns off my computer monitor (dvi)

[KRune]

My setup is as follows:

Windows 8.1 HD Graphics 4600 video bios 2170 driver 10.18.10.3412

I have a https://www.komplett.no/k/ki.aspx?sku=782481 ASUS H87I-PLUS with a https://www.komplett.no/k/ki.aspx?sku=780482 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.

If both monitor and reciever/projector is on, I turn off the projector, my monitor goes blank. Turning off the reciever and on again will restore my monitor !! (even though they are not connected). So the HDMI port needs an "active" connection for the DVI to work.

I do not think badly of you try to Convens. In the practice you use extend dual screen. ?

I finally managed to install Asus drivers manually via device manager rather than setup. Installed fine, but also these drivers have same problem. As soon as I turn off my Projector or Reciever my monitor is also turned off.

Ooh, not if we're going to cut the veins or leave them grow longer.

I need to think. Do not forget you but I'll tell you something and later.

Sorry if you do not mind let me see your computer via remote. I know you know what has been doing for the conversation, but I am at a point that is better than what you say and see if I can help or not. Whenever you're okay.

Sorry I don't see how you can help with this issue with remote desktop. It's a driver issue, and maybe some registry setting or disabling a service might affect it. But I fear an driver fix som Intel is needed. If only I could get their attention to the issue.

[AMart52]

Well yes.

I was with the best intention. Just in case you didn't something good. To review it.

Well, then we left. Greetings and hope you have luck on your problem.

Like I tried to say, changing to single monitor output before turning off projector does not help.

I have not tested with windows 8.1 shipped drivers. I will try that now, to eliminate if problem is limited to intel provided drivers or not.
