I know I am late to this question, but I own the "MacBook Pro (Retina, 13-inch, Late 2013)" with "Intel Iris 1536 MB". I am currently using the macbook with the "Samsung SMS27A850" according to the system preferences it is currently running at 2560 x 1440 @ 60 Hz using the DisplayPort/Thunderbolt connection (not HDMI).

Screen Saver is under System Preferences > Desktop & Screen Saver > Screen Saver, not System Preferences > Energy Saver. Simply navigate to this preference pane, then in the bottom left corner, select the Start after: menu and choose Never.

I'm using an app called Caffeine. It's free and can be downloaded from the Mac App Store. Link: https://itunes.apple.com/se/app/caffeine/id411246225?mt=12

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 ...

The is a firmware update that can help resolve this issue: https://support.apple.com/en-us/HT201158 One reason I think it occurred for me is the adapter that was in use. Hope this helps.

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...

Go into System Preferences, hit the unlock button at the bottom left corner, then Authenticate. Click Show All at the top. Find "Displays," not Desktop and Screensaver. Change the color RS86A and then try to set it to the Highest Resolution. It should render everything you see at 1200x800 resolution at the least.

SwitchResX works for me: you can easily disable displays in its GUI.

I found the answer after pulling my hair for a few days... I actually had to tick the "Displays have separate Spaces" option in System Preferences => Mission Control Does this setting depend on the monitor that is plugged in? I would suppose the answer is yes, otherwise it would not work with my home monitor... To be tested and confirmed!

It is also happening to me, and I can't find the solutions either. But I figured out how to avoid it. When booting up mac turn off monitor first and then power on the mac. turn on the monitor after the mac finished boot or in the login screen Settings Open system Preferences > Energy Saver Click Power Adapter tab(assuming your mac is plugged in) and ...

The USB cable is only for the ports in the back of the display. If you don't intend on using them, you don't need to plug it in. USB 2.0 has a max cable length limit of about 5 meters. You could get an extension cable that keeps you below that limit and it should make things work smoothly.

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.

You can't make items appear twice on what is essentially the same desktop, but you can view the contents of your desktop as a folder. The simplest method using default settings is to open a new folder in Finder, Cmd ⌘ N , then Desktop should be one of the Favourites on the Sidebar.

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 ...

For specific X11/XQuartz problem, here is a solution I found. Pre-requisite First, you will need xdotool.

Definitely thunderbolt to thunderbolt. Also my BenQ has HDMI so you could do it HDMI -> HDMI

I don't think it is possible...

That video adapter only supports resolutions up to 1080p. You would need one that supports 4K resolutions, like this one.

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 ...

I suggest Amphetamine, downloadable from the app store or here. Using the app, you can set up custom periods for your computer to sleep.

I have the same issue with 30" Cinema and lot of HDD connected to the dock. I am using macbook pro retina with two thunderbolt ports so after switching the big monitor to the second port directly on the mac the monitor is not reseting itself. The external HDD still does though and that one goes directly thru the dock :(

The way to "fix wrong subpixel layout setting on Mac OS" is using System Preferences, Display, Rotation 180 degrees (from Standard). This makes an external LED display switch from BGR to RGB pixel orientation. However you also complain your fonts look terrible. Under System Preferences, General, uncheck Use LCD font smoothing when available. Now ALL fonts ...

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 ...

Yes you can run 2 displays If you have an iPad pro iPad iPad Air 1/2 There's an app called duet display 11.99 GBP Then a free download from duetdisplay.com to install the app on this model of iMac Turn off iTunes backup to save space Open the app on iMac Connect lightning or 30 pin from usb on iMac to iPad model Open app on iPad model Et voila ...

I think it has to do with the timing. Did you connect your Thunderbolt cable before or after your iMac reached the login screen? I do not know how target display mode is programmed, but I think all sound drivers on your iMac should be initiated first, before you connect the cable. So when sound is not working, my simple solution is: CmdF2 out of target ...

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 ...

Since you have already un-checked the "Auto-adjust Brightness" option in the display settings, try resetting the System Management Controller (SMC). This may resolve the issues related to power management. Follow these guidelines to reset the SMC. One of the indicators that your SMC might need to be reset: The display backlight doesn't respond correctly ...

You need HDMI connection, VGA is analog, it doesn't allow higher resolutions.

I am currently building a PC and may have an answer to your question. It's has a rather powerful graphics card with 4 DisplayPort ports. Doing some Internet research, I was able to find a couple people who used a simple adapter such as the 6in DisplayPort to Mini DisplayPort Video Cable Adapter that converted output from the DP to the MiniDP Please note ...

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.

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 ...

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

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.

I believe it will only show up as internal if it's connected to the internal bus on the motherboard. Anything else will display as external. You can change the icons if you want it to look like an internal drive from Finder.

If I understand you correctly, what you are looking for is a video capture device. The way it works is video that is sent out from another source like a game console, DVD player, or even another computer it captured by this device and encoded to video. One that a client of mine has used and seemed to like very much is this one by Elgato Now, if you are ...

A Retina display's default resolution is 1440x900. I believe the screenshot feature takes a screenshot of what the monitor "seeds", so a 2560x1600 resolution of a 1440x900 screen. I'd have a look at RetinaCapture, an app designed to take screenshots on a Retina Mac.

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 ...

You can run one external display at 3840x2160@60Hz, or two external displays at 2560x1440@60Hz. There are two thunderbolt connectors, but only one thunderbolt controller, which only has the bandwidth of a single DP1.2 port. If you connect two UHD (3840x2160) displays, I'd expect both of them to run at 30Hz. Contrary to my expectation, I have two UHD ...

As the OP and other answers have noted, the Task Switcher follows the last-moused-over dockbar. To eliminate this behavior in all cases, hide the menu bar on your secondary monitor: System Preferences Mission Control Turn Displays Have Separate Spaces to OFF Of course this will impact your use of Spaces with multiple monitors, but it might keep you ...

I have a different solution. I have the late 2013 macbook pro with retina display. My trackpad click is erratic. I could get it click if I pressed on the trackpad thinking that my battery was expanded and inhibiting the trackpad. But this solution was fleeting and not consistent. I tried to slip a thin paper in the seam and work it around the trackpad. Some ...

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.

A more convenient solution than logging into another user could be the Shades preferences pane which allows you to dim the screen to a degree where it's not noticable that it's on. Combined with muting the audio after remotely connecting this allows you to login to an already logged on user without concern to others. However the security and privcacy ...
