I have a pair of Dell U2414H monitors in a DP daisy chain. Frequently, one or both of the monitors at any given point will not show a display following the PC/monitors coming out of sleep. The monitor is not picked up by the PC at all, and the Intel "DisplayPort Topology" tool can see the monitor, but unable to see the model number.
To resolve this issue, I will have to physically disconnect power from the monitor, plug it back in, and it will begin to work again... until the next time the PC comes back from sleep.
By frequently, I mean 90% of the time the display fails to show anything.
I am using the latest drivers from the support site.
Is this a known issue with these monitors? Any firmware updates?
