hey chris, I've just followed those steps exactly and tried a number of times, and still the same problem occurs

dimma88,

Since you have tried it with three component devices, get it replaced. If you have a service tag number associated with your monitor, you may use Chat or Email support to setup the monitor exchange. If you only have an Order number associated with the monitor, you must call in, 1-800-624-9896. They will need the following information -
20 digit PPID number on back of monitor
Name, address, phone, email address
Order number
