U2415, blacking the screen out

Question

Hello, I have a U2415b monitor that will go black when anything refreshes the screen, such as logging into the computer or doing a switch user on Windows 7. The PC has an Intel i5 processor, monitor is hooked up display port to the PC. I have a second U2415b monitor hooked into the other display port connection on the PC and it has no issues at all. I have swapped the monitor to another PC, and it does the same thing. I have taken another U2415b monitor I had and put it in place where the original one was and it works with no problems at all. When it goes black, you cannot see the on screen display, and I can turn it off and back on and the picture will come back for a short period and then go black again. Right before it goes black, I hear something coming from the monitor that sounds like a hissing electrical sound. I tried to contact Tech Support on this, but the phone number for monitor support is ringing busy, and has rang busy for the last 3 hours. Chat is out of the question because they need a service tag, which this monitor does not have. I currently have a PC down at one of our doctor offices with this monitor having the issue that it has. Any help would be appreciative.

Unfortunately, without a service tag number, the exchange must be done through Technical Support phone. I think even email requires a service tag number. A small/medium business normally has a Dell AE (Account Executive) ? If your business has one, the AE can setup the monitor exchange via email.
