1. Are you windows being redrawn to the main monitor when it disconnects? If not, then the issue is between your external device and the monitor as Windows doesn't know the screen dropped.
2. How is your monitor connected? HMDI, VGA..?
3. Is it a long or cheap cable? Your monitor could lose synch.
Our algorithm doesn't care if it's a black, white or even pink pixel. We have an equal opportunity driver. Therefore the issue is unlikely to be there.
Thanks,

VMT Alban,
I thought I did provide the logs. You've probably helped me sort the issue with the first point above where the issue is isolated to between the external device and the monitor. Though I did try swapping for another HDMI cable, it looks like what I thought was a good quality, brand name, short HDMI cable was not such good quality after all. A new HDMI cable seems to have fixed the problem.
The monitor performs much better but still can't handle a full white screen at 2k res without disconnecting and reconnecting. As you indicate, I suspect this is more likely a hardware syncing issue. Perhaps my 4k capable device is not even up to 2k. I'll see what happens when connected to a 4k TV HDMI input.
Regards Roderick
4k tv HDMI input works fine with the video device driven straight from the TAP20 usb port. As I don't have a Y usb lead I'll have to conclude that neither the TAP20 usb output or the powered usb hub in the 2k monitor (ACER B326HUL) can handle the extra power required for a full or near full white screen in that monitor (for sync?). The powered monitor hub is actually worse then the TAP20 for this issue.
