    Hi everyone

    Today I bought LG FLATRON E2290 one it's new monitor with HDMI, Anyway I back to my home to then use "Mini-display to HDMI cable" and connected to the monitor, in the first the desktop of my mac show up with 1080p resolution on the monitor and it was very nice.... BUT!... The dock, Bar, and the items on the desktop didn't display on the monitor, Then I enable the mirroring and everything show up but the 1080p resolution didn't work! the monitor transform to 720p or less and not sharp like on the first!!! :(((

    This is the Mac Pro forum (desktops). You will probably get better help in the MacBook forum (laptops).

    Mirroring will result in the problem you experienced when the two displays have a different resolution. Do not use mirroring in your situation.

    Sorry about that!

    And about the mirroring... If I don't use it the resolution is truly amazing but the dock, bar, the items on the desktop doesn't display on the monitor!!

    This my problem I want to view all things :(

    the mac is treating the display as an HDTV rather than a computer monitor and is enabling overscan compensation. Connect to a DVI port on the display instead of HDMI.

    Don't do mirroring.

    Elvisizer is right, you have to eliminate overscan. Switching to DVI might do the trick, but it might not. You can use switchresx to eliminate overscan in OS X.

    However, your TV might also have overscan. Make sure it is in a perfect pixel mode, PC mode, or whatever LG calls it. Every brand calls it something different, so you'll have to figure that out for yourself.

    If you want to still use both displays but have the menubar and dock on the external screen, try this:

    Leave your macbook open
    open system preferences
    go to 'displays'
    click 'arrangement'
    Make sure 'mirror displays' is not checked
    finally, where you see the two, blue boxes inside the preference pane, drag the white menubar from the smaller box to the big one.

    I hope this helps!
