Screen layout used

SUMMARY
I have two screens connected to the graphics card, smaller Samsung one is connected via DVI and set to be on the left side and not primary and using 150% scale, bigger one is Panasonic TV and connected via HDMI to Marantz AVR and then this is connected via HDMI to the graphics card. This one is set as primary screen and to the right, using 200% scaling.

When I turn the AVR into standby mode the connection from PC to AVR to TV is set as pass-through (so audio plays on TV speakers) and when returning back from standby the connection is normal and audio is processed by AVR and played via speakers connected to it.

The problem is that when this switching of AVR from/to standby changes screen/outputs configuration and it used to work mostly fine but now the screen positions of windows are forgotten and all windows are moved to the left smaller Samsung screen instead of remaining on the big right Panasonic screen.

This used to work almost fine about on april 25 but now (april 17) that I am back and updated the software it is does not work anymore so something changed during this time frame.

STEPS TO REPRODUCE
1. Move all windows to the right big Panasonic screen
2. Switch AVR in/out of standby mode

OBSERVED RESULT
All windows are moved to the left small Samsung screen

EXPECTED RESULT
All windows should remain on the screen where they are, in my case all should be on the right screen
