If you're using a Mac with an Apple chip and are considering working with two or more monitors, it's normal to have questions: What cables do I need? Will simple adapters work? How does DisplayLink work? Why isn't my second monitor showing up? In this guide, I explain in detail how to get your desktop running like clockwork with DisplayLink on M1/M2 computers, as well as what alternatives and limitations you should keep in mind. The idea is that you can confidently decide what to buy and how to connect it without wasting time.
The key is understanding what your Mac natively supports, when you need a DisplayLink dock, and how to configure macOS to extend or mirror your desktop without the hassle. We'll cover everything from essential hardware (monitors, cables, docks) and necessary drivers to troubleshooting common issues. such as undetected displays, blurry scaling, desynchronization, or overheating.
What is DisplayLink and when do you need it?
DisplayLink is a technology that, using software and a specific chipset in the base/converter, compresses the video signal to send it via USB and then decompresses it in the dock, displaying the image on the external display. In practice, it serves to “add” video outputs to your Mac when it does not support them natively. (as is the case with MacBook Air M1/M2, which only support one external monitor without additional support).
For this to work, you need two things: DisplayLink chipset-equipped hardware (a certified USB-C to HDMI/DisplayPort dock or adapter) and the DisplayLink Manager app installed on macOS. Hardware or software alone are not enough: both are essential.. The quality is very good for productivity; under heavy graphics loads, a slight delay compared to a native output could be noticed, and it is advisable to be aware of the next generation of displays for Mac.
Mac Compatibility and Limits: Native vs. DisplayLink
On MacBook Airs with an M1 or M2 chip, native support is limited to a single external monitor (in addition to the laptop display). This is due to hardware limitations (screen buffers) on these models.. So, if you want two external displays, you'll need a dock or adapter that supports DisplayLink (or similar technology like SiliconMotion's InstantView) and its software.
In the case of the MacBook Pro, most models can handle up to two external displays natively, but it depends on the specific model, the GPU and ports, and the display they mount (for example, the screens of the new MacBooks). In any case, macOS automatically detects the displays and allows you to extend or duplicate the desktop.When you want to go beyond native, DisplayLink is once again the practical way to go.
A very common scenario: you have a Mac with only two Thunderbolt/USB-C ports and two simple USB-C to HDMI adapters. Connecting two monitors this way doesn't magically "convert" one to DisplayLink. If both are passive or "generic" adapters, you will be stuck at the native limit.For one of them to work via DisplayLink, you must use an adapter or dock that includes a DisplayLink chipset in the hardware itself.
What you need: monitors, cables, dock/hub, and controllers
Monitors: You can use Full HD (1080p), 4K, and even 5K displays if your budget allows. Pay attention to the resolution and refresh rate: 60 Hz is usually sufficient for office use, and 120 Hz provides more fluidity. If you value ultra-smooth navigation or light gaming. Check out the available inputs (HDMI, DisplayPort, USB-C) and extras like speakers or a built-in camera. The arrival of 14 and 16 OLED displays is changing the offer when you search for advanced panels.
Cables: Choose the right type for each display and port on your dock or Mac: USB-C to HDMI, USB-C to DisplayPort, or USB-C to USB-C as needed. Use quality cables of the right length for your desk, avoiding jerks and signal loss.
Dock or hub: this is the crux of the matter. If your Mac limits native displays, you'll need a dock that includes DisplayLink (or InstantView) to add software-based video outputs. Check that the model indicates explicit DisplayLink support and that the manufacturer recommends the DisplayLink Manager app for macOS. Also consider the number and type of ports (HDMI, DP, USB-A/USB-C, Ethernet), charging power (100–120 W models available), SD/microSD card reader, and audio.
Drivers: Install DisplayLink Manager (recommended starting with macOS 10.15) or SiliconMotion InstantView (supported on macOS 11 or later) depending on your hardware; Without these drivers and their security permissions, the “extra” screens will not appear., and if errors arise it is advisable to review known incidents on problems with external displays.
Step-by-step guide: from zero to two (or more) screens
1) Install the drivers. Go to the official DisplayLink website and download the DisplayLink Manager app for Mac. Install it and grant it Screen Recording permissions on macOS (System Settings > Privacy & Security > Privacy > Screen Recording). Unlock with your password, select DisplayLink Manager and restart the app. for the changes to take effect.
2) InstantView Alternative. If your hub/dock has a SiliconMotion chipset, download the InstantView app. After installing it, also grant the Screen Recording permission and restart the app.The practical operation is similar to that of DisplayLink.
3) Connect the dock to your Mac. Use a suitable USB‑C cable and plug the dock/hub into your Mac. Make sure the dock's video outputs (HDMI/DisplayPort) are the ones you need for your monitorsIf the dock supports USB-C charging, you can power your laptop at the same time.
4) Connect the displays to the dock. Typically, one output is managed natively (if your Mac supports it) and the other "extra" outputs are provided by DisplayLink or InstantView. Connect each monitor with its ideal cable (HDMI or DisplayPort) and turn them on.
5) Configure macOS. Go to System Preferences > Displays. You'll see a panel for each display where you can adjust the resolution, brightness, and color profile. Decide whether you want to extend your desktop or duplicate your main screen. and drag to arrange the layout (up/down/left/right) according to your table.
Typical scenarios and frequently asked questions
“I have a Mac with two Thunderbolt ports and two USB-C to HDMI adapters; can I make one a DisplayLink adapter?” No, unless that adapter is actually a DisplayLink chipset converter (not a simple passive dongle). To use DisplayLink you need certified hardware plus the DisplayLink Manager app..
"Is it better to use two separate adapters or one dock with two HDMI ports?" If you're looking for stability and less clutter, a dual-output dock is often more practical. Additionally, many docks add 2.5G Ethernet, USB 3.x, SD/microSD and audio, and even 100–120 W of power., centralizing everything into a single cable to the Mac.
“I installed the app, but it doesn’t detect the new monitor.” Check that the hardware is DisplayLink (or InstantView) and that Screen Recording permissions are enabled. Update drivers, try another cable, and change ports on the dock.. Sometimes restarting the app or your Mac unlocks detection.
Daisy chain: what it is and what you should check
Daisy-chaining allows you to connect multiple monitors in series from a single output (usually DisplayPort or Thunderbolt). It's an elegant way to reduce cables, but it depends on the monitors supporting the proper function. and system compatibility.
Not all monitors support this string, and you may need to enable specific options in your (MST) menu. Always consult the manual for each display to confirm compatibility and configuration steps.If your monitors don't support daisy chaining or you want to avoid confusion, a multi-output dock is the most universal option.
Configure image layout and quality on macOS
In System Preferences > Displays, macOS displays each display as a box. You can reposition it so that mouse movement feels natural relative to your desktop. Adjust the scale (text/element size) so that everything looks sharp on each monitor, especially if you mix 1080p and 4K.
Decide whether to extend or duplicate. Extending gives you independent desktops to share apps (pure productivity). Duplicating replicates the same image (useful for presentations). Remember that you can also adjust brightness and color profile per screen. and, if the monitor offers physical controls, fine-tune contrast and color temperature right there.
Real benefits of working with multiple monitors
If you tend to have multiple apps running at once (browser, office suite, messaging, editing), two screens are a game changer. You can dedicate one to the main flow and another to references, communication or auxiliary tools, gaining mental clarity and speed.
Features like full screen and split views help, but nothing replaces extra physical space. It's a direct improvement in productivity, multitasking and comfort., both for office work and for design, multimedia or trading.
Good practices and little tricks
Before you buy, check your Mac's exact compatibility (model/chipset) and native external display support. Also check that the dock/converter declares DisplayLink/InstantView support for macOS.You'll avoid returns and wasted time.
Desktop organization: Place your screens at eye level and align the layout on macOS so the edges match. Good scaling and consistent brightness between monitors reduces eye strain and makes you faster.
Mixed use: If you edit video/photo on the primary display, reserve the native output for that critical display and leave the auxiliary outputs to DisplayLink. This way you will minimize any latency in the window where it matters most to you..
Wireless Plan B: If you're stuck for a cable in a pinch, using solutions like AirDroid Cast can save a meeting or allow you to have a temporary "backup screen." It's not a replacement for intensive tasks, but it is an ace up your sleeve..
With all of the above, you now have a complete map: what limits your Mac, what DisplayLink adds, and how to fit monitors, cables, and a good base so everything works without surprises. With the right hardware, properly installed drivers, and a couple of tweaks in macOS, moving from a single screen to a robust multi-monitor environment is a matter of minutes, gaining order, focus, and real productivity.
