I bought a aoc full hd led monitor to connect to my new MacBook and it looks terrible (using mirror). Yet if I boot off my windows partition it looks amazing, no drivers, settings adjusted or anything, it just works (using the windows max resolution setting).

 

When using the apple os, my laptop screen is sharp and colourful, but the external monitor is no where near the same. It's 'fluffy', there are lines going top to bottom every now and then and everything wobbles like your apps on an iPhone when you delete them. I've tried everything in my monitors menu and no joy. There are no settings on the mac settings for the monitor (like you get in windows). Any ideas?


MacBook Pro (15-inch, Mid 2012)

    Hi a,

     

    Have you tried extended display? If you've literally tried every combination of every setting in Display Prefs, then it's possible there's an incompatibility between the monitor and the Mac.

    Ideally I want to mirror. It works fine on the same machine using windows. Your probably right, it's apple restricting its users and they won't work together. I can't see why they don't give any options or a way of config/driver installs like windows do. Does that mean I probably have to spend 7 times as much and buy an apple monitor or one approved by them?

    No, many people use other brands of displays.

     

    Have you tried extended display?

     

    Have you run all the latest updates in Software Updates?

    Ok, so it looks much better extended, and the same if I close the MacBook (not advised due to heat I've read) but very bad in mirror. It is still slightly wobbly and I get the odd line top to bottom (all other refresh rates greyed out) but its better. Looks like a refresh problem, but no settings to adjust.

     

    How can it be so much better in the windows side if I mirror? What does windows do that apple can't? It's the same machine, just two different os's, yet windows have it sussed.

    In mirror, are the resolutions set the same on both the MBP and the external monitor?

     

    Have you run Verify or Repair Disk in Disk Utility yet? I think it's possible that the area of the disk that MS runs on is ok, but there's a small corruption where that section of the Mac OS resides.

    The monitor is set to auto and the MacBook to its highest. The only refresh available is 62 hertz. If I have it in any mode, it still wobbles.

    I have run those utilities with no faults found.

    See if there's a manual setting on the monitor so you know both it and the MBP are set to the same resolution.

     

    62 hertz is an odd refresh rate. Again, check the monitor to see if there's a place you can sett the refresh rate manually.

    There is no setting on the display to change, and no options at all on the mbp to change refresh rate. I can only change the resolution and this don't stop the wobble or lines. It's real bad. It's not the monitor as I've tried it on other machines, and its fine on the windows 7 in boot camp. It's like there is a driver problem maybe or the graphics card is crap in Mac OS. Like I said, looks great in windows, but the wobble is unreal in mac. Do you think I need to take the laptop for testing?

    Yes, if you've followed/performed everthing I suggested here, I'd bring the Mac and the monitor to an Apple Store or AASP and have them take a look at it.
