I don't actually know where the root cause of this issue lies or even how to accurately describe it so I will do my best to provide the details of the situation. Hopefully someone will have a better understanding than I do, of what this problem is.
my hardware
- OS: Windows 7 Ultimate
- CPU: i7 3820
- RAM: 16GB
- GPU: GTX 970
- GeForce Driver version: 347.25
- Monitor: ASUS ROG Swift on Display port
- Monitor: LG IPS screen on DVI
- Monitor: TV on HDMI
- ROG swift Resolution: 2560x1440
- ROG swift Refresh: 144Hz
my observations
- When the issue starts I've only been able to fix it with a system reboot.
- I haven't found a way to make the issue happen at will.
- It happens most often when the monitor comes out of power saving mode.
- None of the other displays that are plugged in display the issue
- Power cycling the ROG Swift does not fix the issue.
- Unplugging any monitor when the issue is occurring results in all video output stopping until the system is rebooted.
