After just updating to 10.5.7 on my Mac Mini 2,1 (2GHz) my monitor (Belinea o.display 4_24, 24", connected via DVI) is not recognized correctly any more!

It should be running at 1920x1200 native resolution but is now stuck on a bizarre 1920x1080. Additionally, I found a new tab in my monitor prefs offering TV-Screen options like "overscan".

I tried clearing all caches and restarting the machine but nothing would work!

Please help, since I can't work at a screen with buggy resolution!

I've got an original mac with built-in graphics - so why is this happening!?!?!? This is a nightmare....

Cheers, Matt

Mac Mini, MacBook Unibody, Mac OS X (10.5.6)

    I've got exactly the same issue...
  • MrCrowbar Level 1 Level 1
    Same here:

    Mac Mini, C2D 1.83 GHz GMA950, Samsung LE436 (native DVI res: 1360 x 768). TV has a dedicated DVI port that uses HDMI cables. I'm using a long DVI cable with an adapter to HDMI for going into the TV's "DVI in".

    Before 10.5.7, the TV was recognized as a normal display (when using either DVI or VGA) and I could select the native resolution. Now it's only regognized as an an analog TV (like when using the S-Video adapter).

    4 person with a mac mini to face this problem after the update so far. Still counting. Apple is still looking into this
    Try the basic stuff 1st,
    Unplug everything, restart
    Do a PRAM reset
    Try with a different Display (if you have one)
    and try hitting "Detect Displays". (lastly)

    I'm still surfing around trying to find some answers. Will get back

    Tried all of them (don't have a second display though) including repairing disk permissions... No lock though!

    No need for apple to ease on this issue - but I found a solution that works for me:

    I researched a little and found screenResX (http://www.madrau.com/html/SRX/DL.shtml) which gave me a control panel to manually set up the exact horizontal and vertical sync ranges, as well as the pixel clock and the resolution for my screen. Great tool by the way! My screen now looks more crisp than ever before...

    Tried it too, but the resolution for my TV (1360x768) only appears in the "commons" tab, ich made it "active" and applied, but nothing happened. Rebooted, still nothing. Can't get that app to do the job.

    That's what TM is for.
    Just revert back to 10.5.6 until whatever the issue is is addressed.
  • cizko Level 1 Level 1
    @MrCrowbar: when you are in the commons tab, you need to click into the "active" column asides the desired resolution or - like i did - set up a unique profile for your monitor in the "custom" tab (add one by clicking the plus-symbol at the bottom of the window). then you need to restart your machine and select the newly activated resolutions within the original monitor pref-pane.

    cheers ciz

    That worked, thanks. I made a new custom thing, clicked "Edit...", entered my resolution and "Use simplified settings:" (CTV-RB). After rebooting I just had to select the resolution and "overscan" in the display settings and it's looking good again.

    glad i could help you out here...
  • cizko Level 1 Level 1
    now that's some great advice... btw - as i mentioned before: I solved it already for me..
  • Scratchen Level 1 Level 1
    @MrCrowbar: That actually worked for me too! Using "GTF" didn't, but "CTV-RB" did!

    Although this fixed it, I see it as a temporary fix. Apple needs to get a fix out, soon.

    Thanks! This solved it for me. SwitchResX in simplified mode with CTV-RB mode worked like a charm to get back to 1368x768 (I actually had 1360x768 before so I gained 8 pixels!)
