Working with multiple displays gives you a great sense of workspace freedom and flexibility. It gives you an even greater space to work with your programs and files. But there’s something that gets in the way: your built-in computer display keeps on running but you don’t need it. You want to turn it off to save power and extend the lifespan of your display.
So how do you keep your built-in computer display turned off while keeping your files and programs actively running on your external display?
This is a very easy problem to solve. In fact, it’s so easy that you can set your computer to automatically turn off its own display and push everything to your external display the next time you set it up. This lets you seamlessly work on your files and programs right on your external display without tweaking the settings every single time.
Turn off laptop screen when using external monitor windows 10
Windows computers let you customize your primary and secondary display when working with external displays. This setting allows you to choose whether to keep your Windows desktop running on a single display, being duplicated on both built-in and external displays, or using the external display as an extension of your desktop from your computer.
The following steps will show you how to quickly turn off your Windows PC display while keeping your external display running.
Using a Keyboard Shortcut
Step 1: Make sure that the Windows PC and your external display are connected to each other via a suitable connection method (VGA, DVI, HDMI, DisplayPort, etc.) and have been configured correctly.
Step 2: Assuming that your PC and external display are connected, press the Windows and P keys in combination (Win+P).
Step 3: You should see a sidebar showing four different display arrangement modes, namely PC screen only, Duplicate, Extend, and Second screen only. To turn off your built-in PC display and push everything to your external display, select Second screen only.
Step 4: Wait a couple of seconds for the changes to reflect. You should be able to see your current Windows desktop on the external display, and the PC display should be switched off.
The steps above outline the simplest and easiest way to turn off the display on your Windows computer while keeping your external monitor or display running. There’s another way to do this via the Control Panel. Here’s how.
Using Control Panel
Step 1: Make sure that the Windows PC and your external display are connected to each other via a suitable connection method (VGA, DVI, HDMI, DisplayPort, etc.) and have been configured correctly.
Step 2: From any open area on the Windows desktop, right-click and choose Screen Resolution. The Control Panel window for the display settings should pop up.
Step 3: Your computer should be able to identify which display is labeled as either “1” or “2”. To know which number identifies your external display, click the Identify button. Both the built-in and external displays will momentarily flash the number that corresponds to their identity. Airmail 3 6 55 – powerful minimal email client login. (Note: external displays are commonly identified as the 2nd display, bearing the “2” label. For the sake of clarity, we will treat the external display as the 2nd display.)

Step 4: After identifying your external display, click the dropdown menu for Multiple Displays. Then select “Show desktop only on 2” and click OK.
Step 5: Your PC display should turn off in a few seconds, and your entire Windows desktop and open programs will show up on the external display. To save this setting, click “Save changes” on the pop-up window.
Turn off macbook screen when using external monitor
Portable Macintosh computers have a so-called “clamshell” mode – this allows you to close the lid of your portable Mac while running your desktop and programs on the external display. It lets you save some space on your desk while also saving power and extending the lifespan of your Mac laptop display by preventing screen burn-in.
These steps will show you how to enable clamshell mode on your portable Mac so you can run your files and programs on an external display while keeping your Mac laptop display turned off.
This method requires an external keyboard connected via USB or Bluetooth in order to work successfully.
Via Clamshell Mode a.k.a. close laptop and use monitor
Step 1: With your Mac laptop turned on and running, close the lid to activate sleep mode. It is very important not to shut down your Mac.
Step 2: Connect your Mac to power, pair it with a keyboard-mouse combo, and plug in your external display using any suitable method such as HDMI, DisplayPort, VGA, USB-C adapter, Thunderbolt, etc. (Note: if you’re using a Bluetooth keyboard and/or mouse, make sure to pair these to your Mac laptop before putting it to sleep. Otherwise simply connect a USB keyboard and/or mouse to your Mac.)
Step 3: Press any key on your connected keyboard and wait for the external display to wake up and show your Mac desktop.
You can also do the same thing by heading over to System Preferences. Here’s how.
Via System Preferences
Step 1: Make sure that your Mac and external display are connected using any suitable method (HDMI, DisplayPort, VGA, USB-C adapter, Thunderbolt, etc.)
Step 2: Click the Apple icon on the top left corner, then click System Preferences.
Step 3: On the System Preferences window, click Displays.
Step 4: Next, click the Arrangement tab and tick the checkbox labeled “Mirror displays”, then close the lid of your Mac laptop or put your Mac into sleep mode.
Step 5: Connect any compatible keyboard and mouse to your Mac. (Note: if you’re using a Bluetooth keyboard and/or mouse, make sure to pair these to your Mac before putting it to sleep or closing the lid. Otherwise, simply connect a USB keyboard and/or mouse to your Mac.)
Step 6: Press any key on your connected keyboard and wait for the external display to show the contents of your Mac desktop.
Why You Should Disable Your Built-in Computer Display
If you’re someone who works with several open windows and applications at any given time, working on larger external displays is truly a great thing. Turning off your built-in computer display lets you consolidate your entire desktop onto your external display for a more focused and clean-looking workstation setup.
Disabling your built-in computer display also extends its usable lifespan, since it prevents screen burn-in as a result of extended display of static images. If you’re using a portable computer that uses an organic LED (OLED) display, this will definitely keep your laptop screen in tip-top shape.
Portable Mac computers also have the ability to show your content on your external display while the lid is closed. In addition to simplifying your workstation and preventing screen burn-in, this feature also saves precious desk space, which is an indispensable feature, especially for cramped or tightly spaced work areas.
Keeping your laptop display turned off while connected to an external display allows you to enjoy a sleeker, more simplified workspace, while also extending the life of your laptop display.

Apple products are usually known for their high build quality and longevity, compared to other manufacturers. However, sooner or later some hard- or software will fail on you. You’re not alone here. As a matter of fact, just in the last four days I spoke to four senior Apple advisors, one Retail Store, one Certified Service Partner and spent many hours chatting with the support…
So a few weeks ago my 2012 15-inch Retina MacBook Pro started shutting down on its own. While on battery power (an nowhere near a charger) the device simply went to sleep.
After repeatedly pressing the power button I saw the low-battery indicator, but after plugging in the device I still had more than 30% battery left.
This is just one case of battery failure, that Apple can’t explain. There are many other people who experience similar problems with their battery as well. Especially when it comes to the following models, for which Apple actually extends its warranty:
- MacBook Pro (15-inch Early 2011)
- MacBook Pro (15-inch, Late 2011)
- MacBook Pro (Retina, 15-inch, Mid 2012)
- MacBook Pro (17-inch Early 2011)
- MacBook Pro (17-inch Late 2011)
- MacBook Pro (Retina, 15 inch, Early 2013)
After hours and hours of research and calls with Apple, I actually found two quick fixes that might even do the trick for you.
Reset SMC to fix battery and other hardware problems
The System Management Controller (SMC) is responsible for a number of hardware inside your MacBook. It controls everything from all the lights in your Mac, the battery, fans and parts of the logic board.
Here are just a few signs that you should reset your SMC:
- Mac fans running too loud
- Keyboard backlight not working as it should
- Unexpected shutdowns or restarts
- Mac isn’t charging
- Icons keep jumping in your Dock

Reset PRAM – fix most of your MacBook problems
PRAM is not to confused with RAM. The Parameter RAM is responsible for storing all the small settings on your Mac. It’s responsible for the “small things” such as remembering your alarm, volume settings, display resolution or even your startup disk. It might not seem that all too important, but if there’s something wrong with your PRAM your MacBook will suffer.
As a matter of fact, resetting the PRAM solves almost all of the problems I have ever had with my Mac over the last three years.
How to reset PRAM on any Mac computer
This is probably the easiest fix there is:
- Shut down your MacBook
- Press the power button and then immediately →
- Press and hold Option-Command-P-R
- Hold until you hear the startup sound twice
- Release the buttons and let your Mac turn on normally
Update to the latest Mac OS
With every new version of Mac OS, Apple developers do their best to fix all of your software problems, some of which might have not played along well with your hardware. Just do yourself a favor and update your Mac to the latest OS.
Don’t worry, you won’t lose any of your data, settings, passwords or whatnot. After upgrading to El Capital I even noticed a slight improvement in my battery life (random shutdowns aside).
Let Apple fix your computer
If you own one of the models I mentioned at the top of the article, it most likely won’t even matter if you’re still on AppleCare or not. However, if you are, it might also be a good idea to let Apple have a look at your device and eventually fix it for you if there’s in fact a hardware issue.
If you don’t want to waste time for a trip without knowing if you actually have hardware defects, go ahead and run Apple’s diagnostics tools to figure it out.
