Unless one of the displays is a Thunderbolt display, you cannot connect two displays to a Belkin Thunderbolt Dock (see this question). As neither of your displays is using Thunderbolt, you have two options: Connect one display to the dock and one to the MacBook Pro. One end of the cable (going into the dock or MacBook Pro) could be HDMI or Mini ...

It is likely not supported. This article (apple.com) says how to use an iMac as a second display but makes no mention of using a MacBook(Pro) as one. Which usually means it is not supported.

Unplugging my second display 'solved' the issue. Not ideal, but an adequate solution for me to get into Time Machine quickly on the odd occasion.

You should be able to and it may be a limitation of the system you are on or any intermediary devices. Here's my setup: Dell Precision M3800 with nvidia Quadro K1100m graphics. Connected out of the Thunderbolt port (by a mDisplay port cable) to a Dell U3014 monitor which is connected to another U3014 (by a full size Display port cable). I had to enable ...

YES. It can be done if your MBP has the extra graphics chip AND you use Displayport as one of the monitor inputs. Click on "About this Mac" "System Report" "Graphics/Displays" and look to see if it has 2 graphics chips one of them being "AMD Radeon R9 M370X" My experimentation has taught me this: 2012 MBPR with extra graphics chip can drive 2x TB-DVI + ...

I tried all the above suggestions, but it didn't work for me. But now, I solved it! After many, many days of frustration and hours wasted. I did a reset on the PRAM and it worked like a charm.

According to this document https://support.apple.com/en-us/HT204154 The MacBook Pro (15-inch and 17-inch, Early 2011) and later have Thunderbolt2 and can handle two thunderbolt displays (2560x1440).

You can use the program ScreenRecycler to use another Mac (or even a PC) as a second monitor. http://www.screenrecycler.com/ScreenRecycler.html

It's possible. You can run one monitor off the HDMI port and another 2 off of the Thunderbolt ports. You can get adapters for both of these. There's more out there than this but here's one Apple sells. http://www.apple.com/shop/product/MB570LL/B/mini-displayport-to-dvi-adapter BTW: Thunderbolt ports can work Mini Display port adapters.

I know you asked this awhile ago, but I have the same model Macbook Pro and don't experience those problems through my MiniPort to HDMI connection. I connect to a 1080p TV from this laptop all the time to watch video, play games, etc. The only time I've ever experienced the lag you're talking about is when I use my projector, which relies on the DisplayPort ...

I just noticed this same bug when I added a second monitor to my MBP. Upgrading to OSX El Capitan (Beta) seems to have fixed it. (Yay!)

Copper-based Thunderbolt cables are limited to max length of 3 meters. Corning sells optical Thunderbolt cables you will need for the distance you specify here. You can get 10m lengths at Amazon for US$299. They come in 30m and 60m lengths for US$659 and US$1299, respectively. I haven't had the need for these lengths yet, but I did the research a few weeks ...

Do NOT use the HDMI video output! Please buy a Mini DisplayPort cable connect your MacBook and U2715H.

Old topic but I stumbled upon it today. If you only want to get images over, there is Skala Preview, it's free and it's good! I use it to look at mock ups. If you have photoshop it can also do live mirroring!

I had the same problem and I used gfxCardStatus v2.3 to switch to Discrete only graphics card and now it works.

You could hit Command + F1 which toggles display mirroring. Then use the laptop screen to do the copy and paste. That way the users still see your main desktop, while you work on your laptop screen.

Yes, I think keeping the power on here is the key. When I remove the magsafe from my MBP it automatically goes to sleep and turns off the external display. If you really want to keep it from sleeping even when you are not connected to an external power source, you can use InsomniaX or Caffeine.

Yes, its called "closed clamshell" mode. In short, you'll need to attach your MBA to a mouse, a keyboard and power: https://support.apple.com/HT201834

Apple says it does: iMac (21.5-inch, Late 2009) - Technical Specifications Simultaneously supports full native resolution on the built-in display and up to a 30-inch display (2560 by 1600 pixels) on an external display A well made Mini DisplayPort to DisplayPort cable should work just fine.

To get a three screen setup (two external screens, and laptop screen) connected without daisy chaining Thunderbolt displays, you need: One external monitor hooked up to the Mini DisplayPort One external monitor hooked up from USB to DVI I am assuming you already have the first item taken care of as it is the easiest. So, let's focus on the second one: ...

Yes, there is a way, in fact I have my rMBP connected to a monitor right now via HDMI. Firstly, I suggest HDMI, because that's what I have and it works well for me. :) Connect the Macbook (from now on, MB) to the monitors. Open up System Preferences. Select Displays (2nd row, 1st item). 3a. You will be greeted with a window for each monitor Select ...

This is a workaround. I have a similar problem to the OP. I found that I can make the display sleep and stay asleep via the command line: pmset displaysleepnow In contrast, the external display wakes immediately after sleeping when I use the hot-corner method. Since display sleep problems can have many causes, my general advice is to try different ...

if you have problems dragging the mouse due to resolution differences between monitors. Go to System Preferences > Dock > "Position on screen:" click "Left" and the doc will move back to the main monitor. You can then click "Bottom" and the doc will move to the bottom.

I had exactly the same problem, with the same monitor, Dell U2713 / U2713H / U2713HM / U2713HMt. I had two of them plugged in to my late-2014 Retina Macbook Pro 15" and only one was experiencing the problem. I tried 100s of different solutions (I can say for sure it's definitely not the cable!) and nothing worked. Just like you, I could get landscape ...

You won't know until you actually get it and test it. HDMI specs say you should get 5v at 50mA. That's not much to start with. You can read about this more from here. You could get more power but it would have to have MHL (mobile high definition link) support. That will be able to give you up to 40 watts. Now, I looked on the Apple site and it ...

I'm having a similar issue with a 2011 13" MBP8,1 (2.7Ghz i7 CPU and HD3000 graphics), and to me it's pretty certain that it's provoked by video-intensive operations. Curiously, Hardware Monitor showed temperatures in the 70C range, quite far from the 90+C temperatures I've already seen while running big compile jobs. I removed the bottom plate and removed ...

There's a tool that allows you to disable internal display: https://github.com/Eun/DisableMonitor. I've been using it with success in the same scenario. Disclaimer: I'm not a maintainer, so I fear I won't be able to provide support in case of any problems. Please use github issues.

In addition to the above, other software solutions are Jinx, who offers a product called ScreenRecycler. Couple this with a VNC client like TightVNC or JollysFastVNC (from Jinx), you pay once for the main computer, and can use any number (one at a time) of other computers as a remote display. This software is currently in Beta, and I found that after 5-10 ...

This is a design feature documented by Apple. You need to cool your Mac and the processor can then speed up again and do the work you want. See this post on ideas for cooling while in clamshell mode. Any reason not to run my Macbook Pro upside-down in clamshell mode? Open the clamshell and make sure there is good ventilation and you are not blocking the ...

You should try SwitchResX. It allows you to create Display Sets defining many variables like placement relative to other displays, setting which display is the primary, etc. Here is the Display Set page showing the options. It even has the ability to set a keyboard shortcut to each Display Set so you can quickly switch layouts, resolutions, etc.

The OS X UI is not resolution-independent, the only thing you can do is to change the resolution. Which is essentially what OS X does on HiDPI screens when switching to Larger Text or More Space, but since they are retina displays, you can't see that the resolution in some cases is not native, which you definitively can on non-retina displays. There is a ...
