    Hello,

    i have an external Monitor (27") from Dell which is connected to my MBP 13" (non-retina) late 2011.

    Sepcs:
    2,8 GHz Intel Core i7
    8 GB 1333 MHz DDR3
    Intel HD Graphics 3000 512 MB
    OS X 10.8.4 (12E55)

    Diagnostics:
    Intel HD Graphics 3000:
    Chipsatz-Modell: Intel HD Graphics 3000
    Typ: GPU
    Bus: Integriert
    VRAM (gesamt): 512 MB
    Hersteller: Intel (0x8086)
    Geräte-ID: 0x0126
    Versions-ID: 0x0009
    Monitore:
    Farb-LCD:
    Monitortyp: LCD
    Auflösung: 1280 x 800
    Pixeltiefe: 32-Bit Farbe (ARGB8888)
    Synchronisierung: Aus
    Eingeschaltet: Ja
    Integriert: Ja
    DELL U2713HM:
    Auflösung: 2048 x 1152 @ 60 Hz (this is wrong, it's set to 2560x1440!!!)
    Pixeltiefe: 32-Bit Farbe (ARGB8888)
    Monitor-Seriennummer: ***********
    Hauptmonitor: Ja
    Synchronisierung: Aus
    Eingeschaltet: Ja
    Rotation: Unterstützt
    Verbindungstyp: DisplayPort
    Fernseher: Ja


    For the connection, i use a mini Displayport to Displayport cable.
    If i set the Resolution to 2560x1440, i get a lot of blackouts on the external monitor (every 20 seconds, at least 2 seconds long).

    What i know is:
    it is NOT the Monitor (it's working with a 15" mbp with different graphic card; furthermore i got two dell-screens, same issue on both)
    it is NOT the cable, i tried 4 different from different production-companys.

    What i did:
    i reseted the smc and pram with no changes.
    i tried Apples mini DP to dual-dvi adapter (99$) which has the same problem.

    What is working:
    It is working under Windows 7 (Bootcamp) without problems!
    It is working, as soon as i close the MBP and use only the external monitor!!!
    It is working with lower-resolutions.

    I googled a lot today but couldnt find People, with the same problem.
    So, any ideas??


    Thanks in advanced!
