How to prevent refresh rate auto switching?

Post by piece » 29 Mar 2015, 05:49

Hello,

I've got a GTX 780 and connected to that an Acer XB270HU via DP and an Acer XB270H via DVI. Both running at 144 Hz without any problems. The second DVI Port on the GTX 780 is connected to a Pioneer receiver, which is connected to a Sony VPL-HW40ES. I'm using Windows 8.1.

Now my problem is, every time i turn on the Pioneer receiver, Windows detects a new monitor, both Acer monitors go black for a few seconds and all refresh rates are set to 60 Hz. After that i can set them back to 144 Hz and leave the Beamer on 60 Hz, again without any issues.

Anyone got an idea how to prevent this annoying behavior?
