I have just bought a 590 fatboy and if I install the driver off the CD all is well until the computer has been idle for a while (not sleeping or hibernating, just the screen off), then, when I move the mouse the monitor reactivates but all I get on screen is "static".
If I use the driver that Windows (10) installs I get stuttering with some video files, but don't lose the video signal from idle.

Thanks in advance for any suggestions.
