    Hi.
    I noticed that when using my 15 inch MacBook Pro (Mid 2014 DGPU) on a lower resolution like 2560x1600. I get these horizontal white lines. However when i turn the built in graphics switcher off the lines don't show up. Is this normal?

    I don't have my MBP in front of me, but I don't recall every seeing what you state when I've modified my resolution. :(

    I have had 3 units,all the same spec and it's the same problem. This happens only when i lower the screen res to 2560x1600.

    Not normal...take it into Apple I'm sure they'll recommend a GPU replacement
