I'm going to post this as an answer, even though it's not the one you probably wanted... Your issue is that you have one app spread to two Spaces. There is no fix for this at present, short of duplicating the app & re-defining it at OS-level to be recognised by the System as an independent app [which, as I understand, must be done at compile. I'm not ...

I wrote a small C program to accomplish this, as this cannot be done any other way effectively. You'll need Xcode installed to compile it. https://github.com/stnvh/cgorigin #import <Foundation/Foundation.h> #import <ApplicationServices/ApplicationServices.h> #define MAX_DISPLAYS 10 static CGDisplayCount dispCount = MAX_DISPLAYS; static ...

The reason is because when you connect an external display, even if you close the laptop and use it in clamshell mode, the laptop automatically switches from an integrated video card (this uses much less power) to a more powerful, discrete video card (this uses a lot of power). This is also true regarding Intel Iris Graphics, which has different power ...

Unfortunately, this can not be done. This is controlled by Finder, and there is no variable accessible by Terminal.

Not according to EveryMac who are usually spot on with their info, including unsupported 'hacks', none of which are mentioned for this model. This model can simultaneously support the internal display at full native resolution and up to 4096x2304 on an external display in both extended desktop (second workspace) and video mirroring (internal display ...

While I don't normally like to post 'link only' answers, this needs to be an exception. The answer to your question will largely be 'it depends on the MacBook'. To help you figure it out, I recommend going to EveryMac.com's MacBook Pro section. This site will list the technical specs of every MacBook, including the maximum external resolution. For ...

If you have another keyboard and another mouse you can close your MacBook Pro : If an external display is detected and the MacBook is plugged to the power, you can close it without any software.

In addition to the "sleep corner" mentioned in Tetsujin's answer, there is also a small app out there called Caffeine which you can use to prevent the machine (and thus display as well) from sleeping. Note that it will even stop a laptop from sleeping when the lid is shut, so be sure to disable it. There are also alternatives like Amphetamine and Owly that ...

Try System Prefs > Desktop & Screen Saver > Hot Corners. I have mine set like this... just shove the cursor to the top left of the main screen & no more nodding off...

It's definitely not feasible, and likely impossible. Whatever ports are for video and audio on your MacBook Air would be out, like to an external display, not in. You could possibly disassemble the MacBook Air and spent an absolutely ridiculous amount of time (and maybe money) to maybe get it to work, but really, you just need a separate display.

I would go from your mini DisplayPort (mDP) to DisplayPort (DP) or go HDMI to HDMI from your MBP to BenQ. The reason why is that DP (newer standard) supports HDMI (older) signaling quite easily through a passive adapter, while going from HDMI to DP requires active conversion. This is probably the reason it's not working. I have run into this problem ...

You can keep your Mac on forever when you need to (including while AirPlaying) without digging into settings if you download the Mac app Caffeine. With Caffeine, a coffee mug will appear on your Mac's menu bar. Just click it to prevent your Mac from sleeping indefinitely, and click it again to allow it to sleep. This is a very simple method of keeping your ...

Try something like this: https://itunes.apple.com/us/app/amphetamine/id937984704?mt=12 With just a click you can keep the display on for a set or indefinite amount of time.

Take a look at this Article (4 screen set-up), http://www.zdnet.com/article/making-it-work-four-displays-on-a-monster-imac/ where he has three additional screen connected ....

I have finally figured out how to do this: pmset displaysleepnow That will actually put the display to sleep without suspending the entire machine. Amazing how hard it is to figure out how to do something so basic.

If the work is not GPU intensive you might try to manually switch from the Discrete graphic card to the Integrated (Intel HD Graphics). Should work for all 2008-2012, 15-17" dual-GPU MacBook Pros. By installing gfxCardStatus you can do this from the menu bar.
