Repeatedly disconnecting and reconnecting

[Roderick]

Hope you can help. I have followed all the relevant fault finding steps for this problem numerous times, including running through a USB3 hub (mains powered) on the monitor, though I cannot manage to resolve a driver issue with Intel(R) HM76 Express Chipset LPC Controller - 1E59 and Win 10.

Resolution of 2048x1152 is fine but 2560x1440 (max res of the external monitor) stops and starts as per the subject. As the problem is consistent and also exacerbated by more white space on the screen, I enabled the advanced logging and repeated the fault condition recording. This time though a Firefox browser with mostly white space was maximised on the external monitor and the problem changed to the external display being blank all the time.

Regards,

Roderick
