According to this page, this is a known bug in OS X. The Apple Forums suggest reinstalling OS X; I tried reinstalling but I still couldn't access the Display Preferences to rotate my display. I did find a solution that worked within OS X 10.10.3. What I did was connect the Macbook via HDMI to my TV. I found that I could access the Display Preferences and ...

Yes, it's true, and it's not related or limited to Macs, but more of a hardware limitation. It is my understanding that similar to how normal 29,99 DVI adapters only support 1920x1200 max, and you have to go to 99,99 dual-link DVI if you want higher resolution, the HDMI through these cheaper adapters is likewise limited to a single link, and thus you can't ...

From Everymac… In addition to the internal display, this model can support an external display up to 3840x2160 via Thunderbolt 2 (4K UltraHD). Third-parties have discovered that it also can support two simultaneous 27-Inch Thunderbolt displays at 2560x1140 each in lieu of a single UltraHD display. I'm tempted to think that 2560x1140 is a typo & ...

Thunderbolt is not backwardly-compatible with any other display technology. It is an active technology, all before it were passive. It is a combination of video & PCIe. You can connect Thunderbolt to DisplayPort, but not the other way round. From how do I connect an Apple Thunderbolt display to a PC? If the Wikipedia article is to be believed (and ...

I've had this with Mavericks a few times, and I found out that in my case changing the Rotation will trigger the OS to recognise the monitor(s) aren't there. Changing the resolution or some other action (besides obvious reboot) didn't seem to work for me.

Thanks. After downloading gunplot 5.0 and installing under Yosemite 10.10.2, gnuplot couldn't "load" the x11 terminal. After pointing the configure file to /opt/X11/include (reconfiguring, remaking, and reinstalling) every worked fine. (I was surprised, too, that X11 is in /opt/X11.)

To Fix this issue do the following while your external monitor is plugged into the MacBook: Open Displays in System Preferences Click on Arrangement at the top of the window If Mirror Displays is checked, uncheck it The position of the two displays should now be shown in the Displays Window One of them will have a white bar at the top. This is probably ...

You can install John Ford's screenresolution utility via brew install screenresolution. Alternatively you can download and compile the source here. Once the utility is installed you can see all available resolutions via screenresolution list. Assuming the appropriate resolution is listed you can set you display with something like screenresolution set ...

Try to force RGB mode on MacBook. Here is how: http://www.ireckon.net/2013/03/force-rgb-mode-in-mac-os-x-to-fix-the-picture-quality-of-an-external-monitor

System Prefs > Displays > Arrangement. Drag one monitor over the other to the opposite side, then move the Menu bar to whichever monitor you prefer. The actual screen is given a large red outline as well as the representation in the control panel as you drag, so you're certain which one is which. BTW, that tenacious holding onto which display is which is ...

No it's not possible to hide it on an unjailbroken iPhone.

I had a similar problem: The "Thunderbolt display firmware update 1.2" kept reappearing in AppStore, even though the uppdate seemed successful. According to Apple the update was successful when the the Firmware Version is 26.2 and the Port Micro Firmware Version is 2.0.7 (visible in About this Mac -> SystemReport). Above versions were correct in my case, ...

You didn't say what version of OS X you are using. Yosemite remembers your settings by default so just set it once.

I often encounter this problem. I found out that unplugging and reconnecting both the adapter from the MacBook and also from the projector cable makes the projection work again.

The 15" and 13" MacBook Pros are vastly different machines. The 15" has a dedicated video card that may help support that many displays. The 13" uses Intel's embedded video hardware, and it likely does not (at least not in OS X). As the user states in that post, it seems technically possible to run 3 in Linux, but it appears restricted in OS X. That said, ...

No, if a cheap cable works between your TV and Mac you won't find an expensive cable works any better, and a cheap cable isn't going to have any effect of your Mac's longevity. Use it and enjoy the fact you could have paid so much more for a cable and gained nothing at all ;-) Additionally, using a Thunderbolt/mini-DisplayPort adapter uses the same ...

Since it sounds like your TV is very old, the problem may be that the EDID it supplies to your Mac is incompatible/incorrect. (EDID is a standard used by both DVI and HDMI that can provide information about the device's supported resolutions and refresh rates.) In the past, I've used an app called SwitchResX to work aronud similar issues, you could try ...

Short answer - No. Longer answer, from Everymac… *Although Apple only reports that this model can support a single external display up to 2560x1600, Intel reports that this model can simultaneously support two external displays up to 2560x1600 "daisy chained" via Thunderbolt 2. The current top spec Macbook Pro, on the other hand, can support 2 ...

Make sure all the ports don't have any dust In them and that all the cords work

I don't believe it is a hardware issue because everything seems to work fine on Bootcamp. The only variable now is the OS. What happens if you unplug the adapter from the MacMini then plug it back in? Does it work?

You can see the current resolution in the Display system preferences. On a Macbook .. Retina, If you have scaled selected for resolution Hover your mouse over the current scaled selection and the resolution will be shown. If you have default selected for resolution then the resolution is not shown. ( I cannot check my non retina desktop at the moment) ...
