10.9 (Mavericks) External Display Problem

Thanks for the great tip 🙂

I have a 2009 Mac mini connected to a Bravia TV with a mini display port to VGA adapter. Prior to mavericks this was a perfect setup, however after upgrading to mavericks , I find that often the resolution will reset to 800x600 after sleep or if the TV is not turned on when the Mac mini is on.

I can get it to display 1920x1080 using the ALT click trick but the image is offset and blurry. I suspect this might be because the refresh rate isn't selectable as we'll. Only a reboot will fix this. Such a PITA having to reboot every time I want to use Plex

I've a macbook air and after upgrading to 10.9 I've got problems with the resolution of my external monitor.

What's solved my problem was buying the original mini display port to VGA adapter! Doh! While trying to solve this issue I've also learned that in display scale properties, if I press option (alt) key while choosing the option I can see more resolution options to select.

Hope this can help.

At least a signal is getting to your monitors....My Macbook Pro (mid 2012) can't even see the monitor after the upgrade. It's black. So be happy-ish.

I have the same problem - the advantage I had was I had two different cables, the DVI cable works the display port cable does not.

If you can try another cable type you may be able to at least use the monitor at a lower resolution.

I had this issue and just fixed it by resetting the graphix card. On a mac book pro. Unplug the extra monitor. Shutdown. Then press the power button and emediately after words press option/command/p/r keys and hold until you hear the start up sound a second time. let it start and replug in your extra monitor.

Hopefully it helps.

I have tried the option/command/p/r key solution a number of times, including right now. This does not work for my MBP/cable/monitor combination (MBP late 2008, mini display port -> display port, Dell u2711). In addition, it screws up one of my printers (it starts printing blank pages on a print command) and I have to delete the drivers and reload them.

I have a late 2012 Mac Mini with a Sony Bravia KDL40somethingortheother. I am having this problem (for some reason the resolution that works best for your monitor is not displayed) and the Alt/click on scaled thing works. But since I installed this upgrade I noticed a "Display Preferences" icon in the menu bar at the top of the screen. It appears that this is a new feature but the execution leaves a bit to be desired. Does anyone know if Apple is aware of these problems?

Thanks but;

The problem is Mavericks will not recognize the mini display port -> display port cable. That is the cable is needed to get the maximum resoluion (2560X1440) on my monitor.

I have used the alt/click combination to get my resolution up to 1920X1080 using a DVI cable.

Sleep:

For those of you using the Alt key solution, you have to do it all the time, right? I often find the screen res has been messed up again overnight or when I wake it up from sleep, but not always. It almost happens every time I wake up the computer just as the monitor is going to sleep. However, if I sleep the computer manually, perhaps it is less likely to happen.

In any cae, the Alt key solution is not permanent for me. It only works until the next involuntary reset.

Cables:

Hmm, there are a lot of posts about cables lately. I am using miniDisplayPort-to-VGA, although I think I have a DVI/VGA adapter somewhere. I experimented with all the ports when I bought this thing.

I'm experiencing the same issue.........

For the not coming back to the correct resolution have you tried Display Menu from the app store. This may not solve your issue but it may make it quicker getting back to the resolution you want.

The cable issue - My monitor has a maximum resolution of 2560X1440. To get that resolution the only cable that will work is the mini display port -> display port. It would appear as though the current build of Mavericks did not include support for this cable / resolution. Right now my monitor is hooked to a DVI cable and it works at 1920X1080. It depends on what is the maximum resolution your monitor is capable of and what cable can provide that resolution.

I tried with Display Menu, but when the wrong resolution issue happens also Display Menu shows only wrong resolutions for the secondary monitor. The only way to solve this bug is unplug the second monitor. When I plug it again the right resolution returns.

Are you using Alt, Diego, because I have the wrong resolution choices until I hold that key down.

I just created a workflow to fix the display since it seems to be happening a lot lately. I don't know much about Automator and this probably doesn't save much time since it's so few steps. Pretty cool, though.

Just press the record button and do what you normally do to fix the problem, then save it. I guess it's like macros in Windows.

Thank you! I will try this way the next time it will happen. Because I'm sure it will happen again soon (4 times today).
