RE: OptiPlex 3040 Dual Monitor display issues
Just to update this post with additional information I've been PMing.
I've got some more details from the customer today.
It could be either monitor flickering off while one continues to work, sometimes both flicker off at the same time. I think this suggests it's not related to the port on the machine. After 1-2 seconds the monitors come back up automatically.
It can happen several times a day or just once or twice, there is no pattern to this and doesen't correlate to anything the users are doing on their machines.
In regards to radio interference, all staff carry mobile phones but I don't think that's out of the ordinary! I wouldn't expect this to interfere with the signal on just two of the workstations?
When they moved the PC to another area, it was connected to new monitors which didn't previously display the issue.
Thanks for any suggestions.
