RE: OptiPlex 3040 Dual Monitor display issues
We never had the issue (at all) until we got the 5040's SFF (3040 in same family?) . Odd blanking, random. Tried replacing monitrs, cables, different cable configs, and reimaging the PC--nothing fixed it...until...
Till one day I turned on a police walky-talkie near the pc and Zoink, the monitors went blank and came back up. hmmmm. Tried it again--same result. tried it a third time, same result. Moved the radio across the room (10+feet)--no issues.
--had another user with a cell phone- left it on desk near the PC--they got the monitor blanking issue. so I tried it on MY 5040 by leaving phone near PC--same thing. When a phone call was coming in (or a text) the monitors would blank out. This was also repeatable.
Now, from my previous thread below, I was told this is MY fault and basically to *** it.
Funny thing is that this NEVER happened on our previous dell computers. Just the 5040 (in our case)
I would guess that you are having the same issue. I would try having your users keep their cells away from the PC's---like 6 ft if possible.
I know its an inconvenience, but according to Dell and their "help" they have here, its" too bad for you".
