    Hi everybody,

    I search a lot and don't find any solution to my issue.

    scenario:
    MPB 13" Mid 2012
    GPU: Intel Graphics 4000
    Display: Samsung SyncMaster SA300 22"
    Resolution for external display: best for display
    DVI connection using mini display port adapter.

    I already done the following troubleshoots:

    • Unplug display from energy source
    • Unplug DVI cable from monitor and mini display adapter
    • Unplug mini display adapter
    • Reset NVRAM
    • Reset SMC
    • Close lid
    • Caliber external display
    • Pull a bit mini display
    • Check for bad contact

    thanks.

    Tried connecting the machine to a different display or something else to your display?

    My guesses are that at best it's a broken adapter, at worst the miniDisplayPort/Thunderbolt-port on your machine is broken and in the middle of those two we have the display being broken.

    I don't have other monitor, but I already plugged my MBP on my tv with another adapter and works fine, so I guess the problem isn't the miniDisplayPort. I'll try change my adapter.

    Thanks for helping

    Hi I bought another dvi adapter (an apple this time) and the problem persists, but now I get one point, if I change the resolution for 720p decrease the noise and stops flicker.

    but I wish use my monitor on full resolution.

    hugs
