Good morning - Is there a test that can indicate whether a fault is in a monitor or in the computer? - My monitor has been acting rather strangely lately. I get horizontal lines travelling up the screen,The screen will shrink in size slightly with the bottom task bar becoming narrower and distorted. - - All these faults are intermittent - Thank you for your time - Ian
Don't know of any kind of tests that will help you, all I can suggest is the trial and error route. Check the graphics card is seated properly, they can come adrift slightly, check all cables and connections and if possible try and borrow another monitor and see if you get the same problem.
