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 ...

The solution that worked for me was to move the dock from the side to the bottom. My set-up: From System Preferences > Dock: Go to your main screen and take the cursor down to reveal the dock. Now try cmd+tab. The tab-switcher should appear in your main screen. I found that I hardly care if the dock is at the bottom since I have it hidden and use ...

Ive seen elsewhere that Mac HDMI doesn't support VGA, but Mini Display Port does, so the solution would be to get a MDP to VGA adapter

Clarification: I have a thunderbolt of mini display to VGA cable, which I had been using to connect an LCD with my old Mac Pro Book for over 4 years. Just bought Retina Mac Pro and when I connect to LCD through this cable only the screen background appears on the LCD display screen. All efforts failed so far to get the word or ppt files or another display ...

OK, I've been doing a bit of research on this topic myself. What I'd really like to see, obviously, is a thunderbolt hub or splitter, etc. There appears to be none, although I haven't seen anything saying that technically its not possible. That said, I have 3 external monitors hooked up to my mac air (mid-2013) as follows: My main monitor that I use all ...

I had the same issue on the same screen (but without the iOS update), and the mini displayport to displayport was the solution: http://smile.amazon.com/gp/product/B004CAGDUA/ref=oh_aui_detailpage_o00_s00?ie=UTF8&psc=1 Good luck.

Displays under System Preferences is it from the OS X built-in UI side. There are third-party utilities like Display Menu that offers additional resolutions. There is also cscreen if you want to do it in Terminal or incorporate it in a script.

I've tried this and yes it does/can work, depending on your setup. So far I've managed to hook a 2012 MBP 13" to a 2012 21" iMac via Thunderbolt, and the cmd + F2 function works once logged in. However, I've not managed to connect to a 2011 iMac (non-Thunderbolt model) using the same MacBook and Thunderbolt cable - I don't have a DisplayPort cable to hand ...

You can bring up the power menu by pressing Control-Eject. You can also directly sleep (Command-Option-Eject), shut down (Command-Option-Control-Eject), restart (Command-Control-Eject), or turn off the display (Shift-Control-Eject) using the keyboard. You can also press any key to wake a sleeping mac. There is no known way of turning on recent Macbooks via ...

From the original answer: Type the following into your terminal: sudo nano /etc/asl.conf. Now, use the arrow key to go to the bottom. When you are at the bottom, paste it the following: ? [= Sender WindowServer] [= Level Warning] [A= Message _CGXGLDisplayContextForDisplayDevice] claim only (There is nothing special, just command+v). Now, hit control+x ...

Your model should support 2 external monitors at max resolution of 2560x1600. Dual display and video mirroring: Simultaneously supports full native resolution on the built-in display and up to 2560 by 1600 pixels on up to two external displays, both at millions of colors. Check your resolution settings, if the cables are working. ...

I've managed to get my hands on some screens now, and even though Apple representatives said it wasn't possible, it indeed is. I have now 2 (two) Dell U2515H connected and a Lenovo at the same time. On top of that, the screen on the macbook pro is actually on. The setup is as following! MiniDP (thunderbolt) --> Dell U2515 DisplayPort MiniDP (thunderbolt) ...

I have had success with my vertical arrangement by hovering the mouse in the orange areas to bring the dock to the top screen. On the bottom screen you can hover anywhere on the bottom of the monitor. In your case, where your monitors are almost the same size, it might be a bit tricky to find a spot on the bottom of the top monitor where the cursor wont ...

A simple approach could be enabling "displays have separate spaces" in system prefs/Mission Control. That would enable menubars on both screens.

You can use a command line utility named cscreen to do that. You can wrap it in a AppleSctipt script or in Automator. You can download the cscreenIntel.dmg from the link provided. In a terminal use cscreen -h to output the internal help information. I have a MBP and a Thunderbolt Display so in a Terminal I want to have cscreen list my displays $ cscreen ...

I just followed http://cordlessdog.com/stay/, works great for me, with a little lag though Once you have stay installed on your mac, you can launch it and store the windows however you want. So whenever you disconnect your displays and connect back, you will have all the windows restored. You might have to add stay as your startup application, because you ...
