Dual Monitors Connected to Docking Station Not Sleeping
I have a couple dozen setups of the same configuration: Dell Latitude E5520 and/or E6520 connected to a Dell ePort Plus docking station with two Dell P2412H monitors connected via DVI. The computer will attempt to put the monitors to sleep and one will stay asleep but the other one with continue to turn on and off repeatedly until the computer sleeps, powers off, is undocked, or woken up. I'm not sure the cause or resolution but it's very annoying and I can't imaging it's good for the monitors to keep going to sleep and waking up... I've updated Video and Chipset drivers and system BIOS. I've tried with Optimus turned on and off.
Any ideas or at least to hear from someone else having the same issue would be great.
Thanks!

We have a Dell Latitude 6530, using a Dell E-Port Plus - port replicator with a NVIDIA NVS 5200M
Win7 Prox64
Originally installed it with 2 Dell P2413H Displays connected with DVI cables to the docking station. Works great except when the OS turns off the displays, then the secondary monitor goes in and out of sleep mode, off and on. Saw a forum noting that using the Display ports would solve this, so purchased 2 Display port to DVI cables and the problem persists.
No sure if it is a setting or a configuration. I can provide more details. But just wanted to chime in, with the "i have this problem too"
Any suggestions would be great
