Hi, I’m Louie. Sorry you had to wait awhile but I’ll do my best to help.

Initially, are all three (3) monitors connected to the same system/computer?

Let's go through a review of the basics:

  • checked / replace the DVI cables;
  • swapped DVI ports;
  • settings for screen resolutrion and other config checked.

Should all of the above check good, then it would be an internal hardware issue.

Are you then considering a DIY (do-it-yourself) repair approach? If yes, do you have access to and familiar with a multi-meter and even perhaps a soldering iron?
