U4320Q, right side of monitor turn dark
Recently in the pass month, the right hand side of the my monitor turned black/dark shadow. I have tired different ports/cables and it still comes and goes. Have also updated all the firmware and drivers and still the same. Any solutions?

* Go HERE
* Insert the private U4320Q Service Tag number to check the purchased warranty status
* Open the online U4320Q User's Guide to page 52. Run the Built-in Diagnostics. You can run the built-in diagnostics only when the video cable is unplugged. If the issue shows on the Built-in Diagnostics, the U4320Q is faulty
