Suggested January 2024 How To Use A Laptop As A Second Or External Monitor

Looking to hook up another screen to your computer? You don’t have to spend money on a dedicated external monitor if you have a spare laptop. Just use Miracast or AirPlay to set it up as your second monitor.

Using a second or external monitor is the best way to increase viewing space and productivity. This can be handy in situations such as when working from home and needing additional screen real estate for documents and applications.

If you use a Windows or macOS device and there’s a laptop around, you can use Miracast or AirPlay to use it as a second or external display. The best thing about the whole setup is that it’s quick, easy, and involves zero adapters, ports, or cables.

Windows: Use a Laptop as a Second or External Monitor With Miracast

Almost all modern Microsoft Windows desktop computers and laptops come with built-in Miracast functionality. It’s a wireless display standard that can send video signals from one device to another, and you can use it to extend or duplicate a laptop display over Wi-Fi easily.

However, there is a couple of requirements to use Miracast:

Both Windows devices need to be on the same wireless network.

Both Windows devices must run the latest versions of the Windows 10 or 11 operating system, including up-to-date graphics card drivers.

If that’s not an issue, work through the instructions below to use a desktop PC or laptop in a dual-monitor setup with another laptop via Miracast.

Set Up Laptop to Work as a Second or External Monitor

You must begin by setting up the Windows laptop you want to work as a second display. To do that:

Open the drop-down menu next to

Some

Windows

and

Android

devices can project to this PC

when you say it’s OK

and select

Available everywhere on secure networks

Work through the rest of the options on the screen and tweak them the way you want:

Ask to project to this PC

: Choose how your laptop prompts for permission when a connection attempt is requested—

First time

only

Every time a connection is requested

Require PIN for pairing

: Choose how your laptop prompts you to enter its PIN when you attempt to use it as a second screen—

Never

First time

, or

Always

This PC can be discovered for projection only when it’s plugged into a power source:

Determine if you want to save battery life by only being able to project to your laptop’s screen when it’s charging.

Rename your PC

: You need to know your laptop’s name to connect to it, so note it down. Select this option to change your laptop’s name if you have difficulty recognizing it from other Windows devices.

Launch

Wireless Display

(Windows 10) or

Connect

(Windows 11) via the Start menu and keep the app open.

You can now project the display from your main PC to the laptop device. To do that:

Select

Connect

Select your laptop’s name and choose to duplicate or extend the screen.

Work through the rest of the settings on the Display settings screen to change the screen resolution, display orientation, and scale of your multiple monitor setup. You can also switch between projection modes—Duplicate, Extend, etc.—on-the-fly by pressing Windows Key + P.

Select

Optional features

Scroll down and check the box next to

Wireless Display

Select

Install

If you want to use your laptop as a separate device but with the same keyboard and mouse, you must rely on a hardware or software KVM (Keyboard, Video and Mouse) solution. To learn more, check our guide to using multiple computer devices with a single keyboard and mouse.

If you use a Mac, you can use Apple’s proprietary AirPlay protocol to use another MacBook or a Sidecar-compatible iPad as a secondary monitor. For that to work, both devices must:

Have Wi-Fi and Bluetooth active.

Be signed in with the same Apple ID.

Have the latest system software updates installed.

If that’s not an issue:

Open the Control Center on the Mac you want to project the screen from and select

Screen Mirroring

Pick the MacBook or iPad you want to use as a second screen and pick between mirroring and extending the display.

If you want to manage how both displays work (e.g., switch around the alignment), open the System Preferences/Settings app and select Displays.

Alternatively, if you want to control both devices with a single keyboard or mouse, learn how to use Universal Control on Mac and iPad.

As you just learned, Miracast and AirPlay offer a quick and easy solution for anyone with an extra laptop wanting more screen real estate alongside their regular PC. Being able to set up everything wirelessly only makes it all the more practical and convenient.

How To Use A Kindle Dx As A Pc Display

Compared with other Kindle models, Amazon’s Kindle DX is gargantuan. Its 9.7-inch E Ink screen provides ample space for reading books and viewing graphs and images. But what if you could use all of those E Ink pixels for something more creative, such as displaying your Windows desktop? As it turns out, with a few simple tricks you can use the Kindle DX as a computer display that can show anything your usual monitor can show. (Granted, E Ink‘s grayscale display can’t perform or refresh as quickly as a color LCD can, so you’re best off using this screen for static content such as documents or Web pages.)

To get started, you need a Kindle DX, its USB cable, and a PC. You also need a few software components:

Kindle-jailbreak-0.10.N.zip, from the MobileRead Forums

Kindle-usbnetwork-0.37.N.zip, from the same MobileRead thread

Kindle VNC Viewer

TightVNC, a VNC server

PuTTY or another Telnet client

Obviously you’re about to do something the Kindle DX wasn’t meant to do out of the box. To make it smart enough for this trick, you have to jailbreak it. Jailbreaking is a pretty painless procedure. Start by connecting the Kindle DX to your computer and waiting for Windows to mount it as a USB storage device (this should happen automatically after a moment). Next, from chúng tôi extract the file called update_jailbreak_0.10.N_dxg_install.bin. Place this file in the root of your Kindle (not in the documents folder).

Important: The update will now fail, and show a warning to that effect. Don’t worry, this is normal; the jailbreak software still worked, and everything is fine. At this point, your Kindle should now reboot itself.

Once the Kindle DX reboots, connect it to your computer again and mount it as a USB storage device. Next, open chúng tôi and extract the file called update_usbnetwork_0.37.N_dxg_install.bin. Place update_usbnetwork_0.37.N_dxg_install.bin into the Kindle’s root directory, and then repeat the rooting procedure I outlined above to install the USB Networking file on the Kindle.

You are now ready to start USB networking on the Kindle DX. If the e-reader is still connected to the PC, disconnect it and navigate to its home screen. Next, tap the Del key on the Kindle DX keyboard. A prompt will appear. Type ;debugOn and press Return. Note the semicolon at the beginning of the command; you can produce it by using the Sym key. Next, tap Del again. Type `usbNetwork and press Return. This command starts with a backtick, which you also produce via the Sym key. Make sure that it’s a backtick, not a single quotation mark. Once you have that, tap Del one last time. Type ;debugOff and press Return.

Great job! Your Kindle DX is now ready to create a virtual network with your PC, over the USB connection. Use the USB cable to connect the Kindle DX to the PC.

To whip your Kindle DX into shape as an auxillary PC display, tap the Kindle’s aA button and reorient the screen so that it is horizontal (like your computer monitor). Make sure that TightVNC Server is still running on the computer–you will be connecting to it in a moment.

[root@kindle root]# /etc/init.d/netwatchd stop

[root@kindle root]# /etc/init.d/powerd stop

[root@kindle root]# /mnt/us/kindlevncviewer/kvncviewer.sh 192.168.2.1:1 &

If everything proceeds correctly, your Kindle DX should look like this:

Congratulations! Enjoy your extra display.

How To Use Your Iphone As A Webcam On A Pc/Mac

If you have an iPhone, you don’t need to buy a webcam to do video calls from your Windows and Mac machines. There are ways to turn your iOS-based device into a webcam that lets you see the contents from your iPhone’s camera on your computer’s screen.

These apps that let you use your iPhone as a webcam are free but come with limited features. You can always upgrade to their paid pro versions and get access to all the features they have to offer.

Table of Contents

If you’re a Mac user, you have an app called EpocCam that allows you to use your iPhone as a webcam for your machine. The free version of the app supports video resolutions of up to 640 x 480 pixels and works over both wired and wireless (WiFi) connections.

You’ll see the live footage of your iPhone’s camera on your screen.

The ability to use an iPhone as a webcam isn’t limited to Macs. If you’re a Windows user, you have an app called iVCam to stream the content of your iPhone’s camera to your Windows machine.

Like Mac, you need to install a tool on your PC and an app on your iPhone to start using your phone as a webcam with your computer.

Open a browser on your PC, head over to the iVCam site, and download the iVCam software to your computer.

Install the iVCam software and reboot your computer when it’s fully installed.

Open the iOS App Store on your iPhone, search for iVCam, and install it.

Launch the iVCam app on both your iPhone and Windows computer.

Accept the prompt by tapping OK on your iPhone. This’ll let the app use your iPhone’s camera.

You’ll instantly see the live footage of your iPhone’s camera on your computer.

iVCam comes with features like the ability to take a screenshot and record your iPhone’s camera footage. You can use the icons in the app’s toolbar on your PC to access these features.

On the iPhone app, you have features like turning the flashlight on and off, flipping your camera angle, and switching the cameras. You can tap the X icon when you want to stop streaming video to your PC.

If you can’t see your iPhone’s footage on your computer, there might be issues with the iPhone restrictions. You can verify and change these restrictions, if required, on your iPhone as follows.

You need to enable an option on your iPhone, if you haven’t already, to allow the installed apps to use your camera.

Launch the Settings app, scroll down, and tap Privacy.

Select Camera on the following screen to change your camera settings.

Turn the toggle for your webcam apps to the ON position. This’ll allow these apps to use your iPhone’s camera.

If you can’t hear your iPhone’s audio on your computer, make sure you’ve allowed the webcam apps to use the microphone.

Open the Settings app on your iPhone and tap Privacy.

Tap the Microphone option to view the apps that can use your microphone.

Enable the toggle for your webcam apps to allow them to use the iPhone’s microphone.

If you want to use your iPhone as the primary webcam on your computer, you’ll want to set your phone as the default webcam in your video calling apps.

The following shows how to set your iPhone as the default webcam in various video calling apps on Mac. The steps for this procedure should be similar for Windows.

Launch Skype on your computer.

Select Audio & Video from the sidebar on your left.

Launch Zoom on your computer.

Select your webcam app from the Camera dropdown menu.

Open the FaceTime app on your Mac.

How To Share Instagram Reels As A Story Or Dm

Instagram Reels has been in the making for a couple of months now and is finally launched in the U.S. along with 50 other countries. Reels is Facebook’s attempt to enter the short video sharing game. TikTok has a massive social following but is currently under scrutiny in some countries including the U.S. with the current President pushing for its ban. Instagram Reels attempts to fill that void in the market by adding a short video sharing option to its already impressive Instagram app.

What is Instagram Reels?

Instagram Reels is a new feature that Instagram has launched that will allow users to create short videos of themselves from right within the app. In some ways, Reels reflects the likeness of TikTok.

Instagram Reels will be incorporated into the Instagram app itself. It will enable users to create short 15 second videos of themselves. Like TikTok, the function will come with a host of customization options in the way of stickers, filters, music, and more. The introduction of Reels also resulted in a makeover of the social media app. Instagram has introduced a separate ‘Reels’ tab in your profile to display all your content.

How to create your own Instagram Reels

Instagram Reels can be accessed from the camera page on the Instagram app. In addition to creating your own live Reel, you can upload a recorded video to use instead. You can also add a video from your gallery to your Reel, and then record the rest of your Reel!

Launch the Instagram app and swipe right to reach the camera page. Alternatively, you could tap on the story button in the top left corner.

In the panel below, select ‘Reels’. It should be to the right of ‘Story’.

Now hit the ‘Record’ button and showcase your talent! Go ahead and play around with the settings in the left panel to add effects, music, and more to your Instagram Reel.

How to share Instagram Reels

Once you have recorded your Reel and are satisfied with it, you can easily post it to your profile. This is the same as posting an image or video. You can also send it out as a Direct Message (DM) to a person or even add it to your Instagram Story! Here is how you can go about doing that.

How to share your Instagram Reel as a DM

To send your Reel exclusively as a DM to select people, select the ‘Stories’ tab from the top panel.

Now select the people to whom you would like to send the Reel as a DM. You can use the search bar at the top to quickly find your friends on the list. Tap ‘Send’ next to the person’s name to send your Reel as a DM.

How to share your Instagram Reel to your Stories

The same method above can also be used to share your Instagram Reel to your Story. This way everyone in your Friends list can enjoy your Reel! Alternatively, if you have a ‘Close Friends’ list set up, you can decide the audience for your Reel story.

Now tap ‘Share’ next to ‘Your Story’. Tap ‘Done’ at the bottom to complete the process.

The Reel will be added to your Instagram Story. You can view it by tapping the Story button in the top left corner of the app.

How To Fix A Monitor Not Waking Up After Sleep

When my monitor began refusing to wake up from sleep mode, I started researching the issue and quickly discovered that I’m not alone in my troubles. In fact, by my completely unscientific estimates, it seems that everyone has suffered from this at one point or another.

Unfortunately, there is no universal cause for this, so there’s no universal solution. However, seeing as there are several possible ways to resolve this, I’m going to run through some of the most popular causes and solutions to this age-old issue.

Dell monitors (and maybe others) have a special feature called Deep Sleep, which lowers the power usage of your monitor even more than going into regular standby mode. It’s somewhere between outright unplugging in your monitor and just having it in standby.

In most cases, it’s not a very useful feature and can mean that if your monitor goes to sleep with your PC, then your monitor won’t automatically turn on again when your PC comes out of sleep.

Note that other monitor brands might also have this feature, so take a look in your monitor settings to see if you have it, then disable it if you like.

Asus deals with a lot of motherboards, and for the most part, they deal with them quite well, but there are a couple of quirks on them that can cause things to go a little bit wrong. For example, most modern-ish Asus boards have a feature called “PLL Overvoltage” enabled by default. This helps overclock your CPU that little bit more, so if you’re worried about eking out those extra few-hundred MHz out of your rig, you may want to leave it on.

But if getting your PC some sleep is a priority, then you may need to turn this feature off, and to do that, you need to go into the dreaded BIOS.

Reboot your PC, then as it’s booting, press the Delete key until the BIOS screen appears.

Things may vary a bit here from one motherboard to another, but to find the option, go into the “Advanced Mode” (the F7 key on my Asus Z97 MOBO).

Sometimes those seemingly helpful power options in Windows can prove to be a liability, accidentally keeping certain things in a dormant state, even when they’re definitely meant to be on. Here’s how to make sure power management doesn’t interfere with your monitor.

A seemingly simple option but a good one. When your monitor goes to sleep, the connection between it and the cable connecting it is severed. For some silly reason, however, when the connection gets re-established (when you bring your monitor out of Sleep mode), sometimes the monitor doesn’t re-establish that connection, even though the cable is still plugged in. A possible solution to this is to use the buttons on your monitor to switch off the “auto-detect” option.

One of these solutions should solve your woes with reawakening your monitor. While you’re working with Windows, see our list of Windows 10 registry hacks. Also see how to install unsigned drivers in Windows 10.

If you’re a parent like me who is tired of spending a fortune on baby products, you can save a little money on some gadgets with DIY hacks. For instance, instead of purchasing specialized equipment, you can repurpose your phone as baby monitor.

On this list, we will not dismantle the phone but rather try some non-invasive methods that can be easily accomplished through online apps.

Let’s explore some popular baby monitor apps for ios and android phone. We will start with the simplest option and then move on to popular choices on the internet.

Since Skype is available on both Android and iOS, it is the easiest way to set up a baby monitor with your phone. You can even set up a call on your laptop with the Skype app installed. Facetime is only available for iOS devices. You’ll get both video and audio feed on your phone with both apps. The phone already has a battery so you can just plug it in at all times to handle power backup. The drawback of these apps is that the call may end up accidentally or due to network problems. Then, you have no way of restoring it remotely.

If you’re looking for something with less ‘smart’ capabilities, this app is the right choice for you. Baby Monitor MVA is a lightweight app that can run on any Android device. It can send you notification alerts in the form of a call or a text message.

This app is available for free. Also, it does not need Wi-Fi or 3G signal to send you a notification. It also has a sleep log feature that records the baby’s sleeping patterns. Baby Monitor MVA is available only on Android Play Store currently.

Dormi is one of the widely used apps in the baby monitor category. It comes in a freemium model with four hours of monitoring time available for free every month. Dormi has lots of features found in standard baby monitors.

Connection with or without Internet

Seamless connectivity

Multi-device support

Smart noise detection

Dormi can run on devices with Android 2.3 or higher which covers the maximum Android phones out there. It is however not available for iOS devices. With a lifetime license fee, you are covered for all features provided by Dormi.

For anyone interested in home security systems, Alfred will be a familiar name. With over 40 million users worldwide, Alfred has the best expertise for turning the old phone into a baby monitor.

The app is available for both Android and iOS. To set up, Install the app on both phones and sign in with your account. Then, you can pair them together and set one phone as a Viewer while the other is the Camera.

Alfred offers a paid subscription model for their service. Alfred also has a web application if you want to set it up from a PC or browser. Keep in mind that you need at least Android 4.0.3 or higher use on Android phones. Besides that, Alfred has lots of features to offer.

It also has an Android version for android users. It lets you set up devices as a baby station for the baby’s room and a parent station for parents’ use.

You can. Some baby monitors even include wearable accessories. These wearables can record the heart rate and temperature of your babies. They also have better night mode than smartphones.
