Do you have a tablet half-forgotten in a drawer and a laptop whose screen is too small?Combining them to create a small portable workstation is much easier than it seems, and it can also save you from buying a traditional external monitor, which is usually bulkier and more expensive.
In recent years, tons of apps, docks, and native features have appeared. These apps allow you to transform a tablet into a second screen, a touch monitor, a mini control center, or even a pseudo-graphics tablet for drawing. Let's take a detailed look at all the ways to get the most out of them: from using an old Android tablet as an extra monitor, to maximizing the potential of an iPad, a Galaxy Tab S, or a drawing tablet as your main screen for work and study.
Why it makes sense to turn your tablet into a portable workstation
When we think of a monitor, we usually imagine a large, heavy, and expensive panelA 24- or 27-inch monitor with a high refresh rate is a good option. But for many everyday tasks, you don't need that much. A tablet offers something a traditional monitor doesn't: lightness, a built-in battery, and the ability to carry it in your backpack without it being a burden.
Repurpose an Android tablet or iPad as a second screen It has several clear advantages: you can extend your laptop's desktop when traveling, have an auxiliary screen for video calls, chat, or reference documents, monitor your PC's performance while playing, or use the tablet as a "mini whiteboard" to draw or take notes with a stylus.
However, it's important to understand that it's not a perfect solution for everything.It's smaller than a standard monitor, the ergonomics aren't the same, and if you use a wireless connection, you might notice some lag or loss of quality. Even so, as a portable and inexpensive secondary display, it's a very powerful option.
The era of teleworking and the mobile office also comes into play.Many professionals have realized that with an ultrabook and a tablet they can recreate a fairly decent dual-screen setup almost anywhere. You won't have a mega-setup, but you'll have enough to work comfortably without carrying half your desktop. Also, check if the Android tablets are ready for remote work to better adapt your workflow.
Use an Android tablet as a second monitor for your PC or Mac
Android tablets are probably the most versatile and cheapest option. to assemble a portable workstation, and there are multiple guides for replace a laptop with an Android tablet if your goal is to do without a laptop for certain tasks.
The best part is that you can use them as a second screen with almost anything.Windows computers, Macs, and even other Android devices. The connection is usually made via WiFi or USB, and the key is to install one app on the computer (server) and another on the tablet (client) so they can communicate.
When is it worth using an Android tablet as a monitor?
Using an Android tablet as an extra monitor fits very well in several scenarios. where you don't want to or can't put a normal monitor on the table or in your backpack:
- If you want a cheap second monitor And your budget is very limited: a basic tablet can cost you €50-80 and then you only need one app.
- If you move around a lotMeetings at the client's home, coworking spaces, travel... A tablet fits in any backpack and weighs much less than a dedicated portable monitor.
- If you value minimizing cablesSome apps work very well over WiFi, without a single cable between the laptop and the tablet.
- If you don't need maximum color quality or huge sizesbut rather extra space for emails, chats, statistics panels, notes, etc.
You can also reuse old tablets that are no longer useful for much. because they've become slow or run outdated Android. For having an email viewer, a monitoring panel, or a screen to display a video player, they're usually more than sufficient.
Basic requirements: apps, connection, and limitations
For your computer to "see" your tablet as a screen, you need intermediary software.Simply plugging in a cable will not suffice: except in very specific cases with video input, the tablet does not understand a direct HDMI or DisplayPort signal.
In almost all methods you will need to install two pieces of software:
- A program on your PC or Mac (server) that captures the screen and sends it.
- An app on the tablet (client) that receives that signal and displays it in full screen.
The connection can be via USB or network (WiFi / LAN):
- USB wired connectionIt usually offers less lag, more stability and better resolution, but not all apps support it and you'll have to enable things like USB debugging on Android.
- WiFi connectionThis is the most universal method. You only need your PC and tablet to be on the same local network. However, it's highly dependent on the router's quality and network congestion: on poor Wi-Fi, the image may freeze or stutter.
As for the tablet's hardware, the newer the better.A very old tablet with outdated Android and little RAM might work, but you're likely to experience lag, app crashes, or resolution limitations. If it's a reasonably modern tablet, the experience is much better.
The best apps to turn your tablet into a monitor
There are quite a few applications that bridge the gap between PC and tablet.Some are one-time purchases, others operate on a subscription basis, and still others have free versions with time or feature limitations. Here's a summary of the most prominent ones, which are also mentioned in almost every specialized guide.
duet display
Duet Display is one of the veterans and very popular among demanding usersIt was born in the Apple world to use the iPad as a second monitor for the Mac, but now it also supports Windows and Android.
Its strengths are image quality, touch support, and low latency.especially when using a wired connection. It also offers advanced modes such as remote desktop or using the tablet as a basic drawing tablet.
However, it's not exactly the easiest to configure.You need to install a large client on your PC (around 160 MB), log in, let Windows install drivers, and sometimes struggle with permissions. On some older computers, if the video drivers aren't up to date, Windows might detect it as a generic monitor and limit you to resolutions like 1024x768.
Duet Display is a paid service.with different plans (for example, Duet Air with a subscription). In return, if it fits your hardware, the experience is usually very smooth and sharp.
Splashtop Wired X Display
Splashtop Wired XDisplay is one of the solutions with the best "real monitor" feel.As the name suggests, everything here runs via USB, without WiFi, which greatly reduces lag and allows for more comfortable work with video and animations.
It works with both Android and iPad/iPhone.It has versions for Windows and macOS. The mobile app is a one-time purchase (around €7-8), with no subscriptions, although it usually includes a 10-minute free trial to check compatibility.
To use it you will need to:
- Install the software on your PC from the Splashtop website.
- Enable USB debugging on your Android tablet, if applicable.
- Connect the appropriate USB cable (ideally USB-C to USB or USB-C).
Once this is done, in most cases it's just plug and play.Windows detects the additional screen, and you simply need to go to Display settings to decide whether to extend or duplicate it. This is one of the most recommended options if stability and smooth performance are your priorities.
spacedesk
Spacedesk is the best free alternative, at least until the end of 2025.which is until when the developers have promised to keep it free. It works very well, especially on Windows, and supports both Android tablets and iPads.
Its simplest method is via WiFiInstall the driver on your PC, the app on your tablet, make sure both are on the same network, open both applications, and in seconds you should see your PC listed on your tablet. Tap, connect, and you can now configure the extra screen in Windows.
A wired connection might also work better.Although the configuration is a bit more finicky. In any case, it remains a very powerful option for the price: zero euros.
Super Display
SuperDisplay is very focused on those who want to use the tablet as a screen and drawing tabletIt only works with Windows, but in return it offers a high refresh rate (60 fps), pressure-sensitive stylus support, and a fairly fast response time.
It can be connected via USB or WiFiOn many devices, USB works perfectly, although some users only get a good wireless connection. With Wi-Fi, if the network is decent, lag is usually very low, and you can even draw with considerable precision.
It's a one-time payment, with a few days of free trial.If you work with Photoshop, Krita, or similar apps and have a stylus like the Samsung S Pen, it's a serious alternative to a basic graphics tablet.
Other methods with Android: Chrome remote, Deskreen, and others
If you want something specific and without getting bogged down with lots of specialized appsThere are also some more "generic" options that are also suitable for building your pseudo portable workstation.
Chrome remote desktop It allows you to view and control your PC from your tablet using the Chrome browser. All you have to do is:
- Install the Chrome Remote Desktop extension on your PC.
- Configure remote access and associate your Google account.
- Install the app on your tablet or access it from a compatible browser.
The big drawback is that it doesn't extend the desktop, it only duplicates the screen. It focuses on remote access, not on functioning as a true secondary monitor. But it can be useful for accessing your PC from outside the home or for performing small tasks.
Deskreen is another interesting ideaYou install a program on your PC, and on your tablet, you only need a modern browser. You scan a QR code, and you can view the screen or even just a specific window. Ideal for very old tablets without access to an app store, as long as the browser is still functional.
There are also other solutions such as Air Display, iDisplay, Pitikapp, etc. They focus on specific use cases: monitoring PC resources, connecting multiple monitors at once, using Macs with Android tablets… Most are paid apps, so it's a matter of trying them out and seeing which one best suits your computer and your budget.
Key tips to optimize your experience with your Android tablet
Once you've got your tablet working as a monitor, the next step is to fine-tune the settings. so that it looks and responds as well as possible within the limitations of your hardware.
- If you use WiFi, make sure it's a good network.Avoid saturated public networks; ideally, use a decent router and keep your PC and tablet close together.
- If using a cable, use a quality USB cable.Some cables cause disconnection problems or fail with USB debugging; if you can, opt for a short and robust one.
- Adjust the resolution to the highest setting supported by the tablet. without performance suffering; many apps allow you to choose between several qualities.
- Increase the refresh rate when the hardware allows itespecially if you're constantly moving windows or playing video.
- Take care of ergonomics: put the tablet on a stable stand, adjust the angle to avoid straining your neck and, if you are going to use it for many hours, consider using a blue light filter.
Drawing tablets as monitors: a very powerful creative option
If you come from the world of design, illustration or editing, drawing tablets with screens are for you. (types like XP-Pen, Wacom, Huion, etc.) are almost the next level of this idea: not only do you add a monitor, but that monitor is made for drawing directly on it with a pencil.
These drawing screens typically offer sizes ranging from about 11 inches to 24 inches.with very good quality panels, vivid colors, wide viewing angles and, above all, high precision digitizers with pressure sensitivity and, in some models, tilt detection.
In addition to serving as a normal extended monitor for any taskThey allow you to:
- Draw and paint as if it were a digital sketchbook, with strokes that respond to the pressure of the pencil.
- Take handwritten notes comfortably during online courses, classes, or meetings.
- Control the cursor with the pen with much greater precision which is ideal for fine photo retouching or interfaces full of small controls, using your finger.
What you need to use a drawing tablet as a monitor
Unlike an Android tablet, a drawing tablet with a screen does not work on its own.It's basically a monitor that needs to be connected to a computer to display anything.
In general, the process consists of:
- Connect the tablet to the PC or Mac using the included cables (usually HDMI + USB or a single USB-C with video).
- Install the official driver from the manufacturer (XP-Pen, Wacom, Huion…).
- Restart if necessary and configure the screen in the operating system.
Once the driver is installed, the system sees it as just another external monitor.From there you can decide whether you want to duplicate the main screen or extend the desktop.
Example configuration: XP-Pen Artist
Let's take as an example an XP-Pen Artist, very popular among creativesThe basic steps would be:
- Open your system's display settings (On Windows, Settings > System > Display; on macOS, Settings > Displays).
- Decide whether you want mirror or extended modeIf you want a mirrored display, ideally both monitors should share a similar DPI (dots per inch) setting so that everything looks balanced.
- If you choose extended desktopDrag the tablet representation in the settings to place it on the side where you actually have it on the table, and decide whether it will be Monitor 1 or 2.
- Next, open the tablet's control panel. (XP-Pen software) and, in the monitor settings section, indicate which system screen it corresponds to so that the pen is aligned correctly.
Once you've done this, you'll have a very serious workstation.: a main monitor for the general interface and the drawing screen for the canvas, video timelines or any task where the pen makes a difference.
Large models recommended for comfortable work
If you want to go a step further and set up a system that serves as both a second monitor and a large canvasXP-Pen's 22-24 inch models are a very well-balanced combination of size, resolution, and price.
- XP-Pen Artist 24 ProA 23,8-inch panel with 2K QHD resolution, vibrant colors, and 20 programmable physical keys. It's a huge screen where you can display your software interface and canvas in a large format, and still use it as a secondary monitor for office tasks, browsing, or video.
- XP-Pen Artist 22 Plus21,5 inches, slightly more compact but still very generous. It supports 16K levels of pressure sensitivity in its pen, allowing for very fine nuances in strokes and shading. It's ideal if you're starting out in digital art but want something serious and comfortable for working long hours.
Both models, and others like them, remain quite affordable. compared to high-end professional monitors, considering that they combine a monitor + advanced digitizer in a single device.
Galaxy Tab as a monitor without apps: the magic of Samsung
If you have a relatively modern Samsung tablet, you may already have built-in what others achieve with apps.The Galaxy Tab S7 and S8 with One UI 3.1 or higher include a feature called "Second Screen" that allows you to use them as a wireless monitor in Windows.
The main advantage is that you don't have to install anything on the tablet. and that the integration is usually quite seamless. Even so, you still rely on a good Wi-Fi connection for a smooth experience. Additionally, many Samsung models offer support for DeX mode and desktop mode, which expands the possibilities for use.
Requirements for using a Galaxy Tab as a second screen
First of all, check that your tablet meets these minimum requirements:
- Samsung Galaxy Tab S7, S7+ or S8 (and derivatives) with One UI 3.1 or higher.
- A PC with Windows 10 (version 2004 and later) or Windows 11.
- Both devices connected to the same WiFi networkwith good coverage.
Steps to activate Second Screen on Samsung
The process is very simple and everything is done in a few seconds. If the network cooperates:
- On the tablet, pull down the quick settings panel from the top and tap on “Second screen”.
- Choose the mode: one designed for drawing/games (prioritizes speed) or for video (prioritizes image quality).
- On your Windows PC, press Win + K to open the wireless connection menu.
- Select your Galaxy Tab from the list of available devices.
- decide if you want duplicate or extend the screen from the Windows projection menu.
The tablet will display the PC screen and a small button to disconnect. When you're finished. For quick meetings, reviewing documents while you type, or watching a video while working on the main screen, it's fantastic.
iPad as a monitor: Sidecar and third-party apps
In the Apple ecosystem, the iPad is the king of portable second screensApple has been enhancing integration with macOS for some time now, to the point that many times you don't need anything more than the system's native functions.
Sidecar is the official feature that allows you to duplicate or extend the screen of a Mac on an iPad.It features Apple Pencil support, gestures, and low latency. All you need is for both devices to be updated and connected with the same Apple ID, and to share a Wi-Fi or Ethernet connection.
Use an iPad as a monitor for your Mac with Sidecar
The steps to link an iPad as a second physical screen in macOS (beyond specific version details) these are usually the ones:
- On the Mac, open System settings (or System Preferences, depending on the version).
- In the side menu, go to Screens.
- Click on the icon "+" that appears next to the detected screens.
- Select your iPad from the list of available devices.
- Configure whether you want to duplicate the screen or extend the desktop, and drag the tablet representation to place it where you actually have it.
From that point on, the iPad behaves like a Mac screen., with an extra bonus if you use Apple Pencil: you can make annotations, draw in compatible apps, or use multi-touch gestures to control windows.
If instead of a Mac you have a Windows PC, apps like Duet Display, Spacedesk or Splashtop come into play.which also support iPad as an additional screen, following the same philosophy as with Android: app on the PC + app on the iPad.
USB-C docks and hubs: your tablet as a connection center
Another piece that fits perfectly into a portable workstation is a good USB-C dockThere are models, such as those from Plugable and other brands, that combine physical support for the tablet with several ports: USB, HDMI, card reader, audio, etc.
The idea is simple: you connect the tablet or mobile phone to the dock, and the dock to an external monitor.On tablets and mobiles with desktop mode (like Samsung DeX) you can have an experience very close to a classic laptop: large screen, keyboard and mouse connected to the dock, and the Android device acting as the "brain".
These docks usually include:
- Others USB-A 5 Gbps for peripherals.
- One or more USB-C, one of them with step load (up to 100W) to power the tablet or laptop.
- HDMI to connect external displays.
- 3,5mm jack for audio.
- SD and microSD card reader for photographers or content creators.
In addition, it serves as an adjustable support.You can position the tablet vertically or horizontally, use it as a second screen while the dock's monitor is the main one, and fold it up to carry it in a small case. However, some models aren't sold in all countries and sometimes need to be imported.
Security, performance, and best practices when using a tablet as a monitor
When you start connecting devices, installing third-party apps, and granting remote access to your screenIt's worth taking a moment to review the security and performance aspects. It's not complicated, but it's better to be safe than sorry.
Some reasonable recommendations would be:
- Activate two-factor authentication in services that allow it (accounts for apps like Splashtop, Duet, etc.).
- Avoid public WiFi networks For long sessions or with sensitive information; if there is no other option, use a VPN.
- Create strong passwords and not repeat them on all the services you use for remote control or second screen.
- Keep your operating system and apps up to date on PC and tablet, to avoid errors that have already been corrected.
- Review what permissions the apps request. and disable anything that doesn't make sense for your case (for example, access to contacts in an app that only streams screen video).
In terms of performance, he acknowledges that not all tablets will perform equally well.Older tablets may malfunction, freeze, or be limited to low resolutions. Use them for simpler tasks (chat, monitoring, text) and reserve the more powerful tablets for drawing, video, or intensive multitasking.
Second screen usage modes in Windows: duplicate, extend, or secondary only
When Windows detects a new monitor (whether it's a tablet or a regular panel)It lets you choose how you want to use it. This decision is key to getting the most out of your portable workstation.
The three main options are:
- DoubleIt displays exactly the same thing on both screens. Very useful if you want to show someone what you're doing without them having to look at your laptop, or if you're using a tablet as a teleprompter while you see the same thing on your main screen.
- EnlargeIt creates a seamless desktop across both screens. You can drag windows from one to the other and work with different apps on each. It's the ideal mode for productivity: code on one side, documentation on the other; video calls on the tablet, presentations on the laptop, and so on.
- Second screen onlyThis turns off the laptop screen and displays everything only on the external screen. This is sometimes used when you connect a laptop to a TV or large monitor and only want to view the content there.
Experiment with these options depending on the type of task you're doing.Giving a talk (duplicating) is not the same as editing video with timelines on one screen and preview on another (enlarging).
Real advantages and disadvantages of using a tablet as a monitor
Using a tablet as an auxiliary screen has many advantages, but also drawbacks that should be accepted from the start. to avoid disappointment.
Among the clearest advantages are:
- Total portabilityYou can set up a dual screen anywhere with a laptop and a lightweight tablet.
- Economic savingsYou reuse hardware you already have instead of buying an extra monitor (and if you buy a tablet, it's often cheaper than a high-end monitor).
- Touch interfaceYou can touch, make gestures, write with a stylus… something that traditional monitors don't usually offer.
- Higher productivityMore space for windows, apps, and documents, without having to switch tabs every two seconds.
On the downside, there are significant drawbacks:
- Size and ergonomics worse than a normal monitorwhich can cause eye and neck strain if you use it for many hours without good support.
- Resolution and image quality limitations on some older tablets or apps that reduce quality to save bandwidth.
- Possible lags and stutters when you depend on WiFi, especially on saturated networks or with poor coverage.
- Risk of distraction if you start using the tablet for messaging or social media while you work.
- Higher battery consumption on the tablet, which may require you to keep it plugged in if the session is long.
For all these reasons, the tablet as a monitor shines especially in mobile scenarios, for occasional use, or as a complement.Whereas for a fixed workstation with many hours of use, a large and ergonomically well-positioned monitor is still recommended.
Ultimately, turning your tablet into a portable workstation is a matter of combining the right parts.Choose the app or feature that best suits your system (Splashtop, Spacedesk, Duet, Sidecar, Samsung Second Screen, etc.), take advantage of USB-C docks when available, and be clear about what kind of tasks you'll be using it for. If you take care of the network, cables, and ergonomics, that forgotten tablet can become the perfect complement to your laptop, increasing your productivity without breaking the bank or burdening you with unnecessary gadgets.
