Adding a laptop second screen is one of the simplest ways to make a home-office or hybrid setup more practical. Instead of constantly switching between tabs, you can keep your main task open on one display and emails, notes, research or video calls on the other.
The difficult part is choosing the right monitor. Bigger isn't automatically better, and specifications such as resolution, panel type and refresh rate can quickly turn a straightforward purchase into a confusing one. What really matters is finding a screen that suits your desk, connects properly to your laptop and remains comfortable to use throughout the day. Here's what to look for before you buy.
Why a Second Screen Is Worth It
A second screen for your laptop gives you more room to work without changing how you already use your computer.
If you're writing a report, you can keep your reference material open beside it. During a video call, one screen can hold the meeting while the other displays your notes or presentation. Spreadsheets also become easier when you're not squeezing several windows onto a small laptop display.
The benefit isn't simply having more screen space. It's reducing how often you need to minimise windows, switch tabs and rearrange applications throughout the day.
You can also keep your laptop open as one of the displays rather than replacing it entirely. For many home-office setups, a laptop alongside one well-positioned monitor provides all the screen space you'll realistically need.
Screen Size and Resolution: What Fits Your Desk?
For most laptop-and-monitor setups, a 24 to 27-inch screen is a sensible starting point.
A 24-inch monitor gives you noticeably more working space than a typical laptop without taking over a smaller desk. Moving to 27 inches provides more room for side-by-side windows, spreadsheets and creative work, but you'll need enough distance between yourself and the screen for it to remain comfortable.
Resolution matters alongside size, too. Full HD, or 1080p, is perfectly usable at 24 inches and can be a cost-effective choice for email, Office work and general browsing. At 27 inches, 1440p is often the better fit because the extra resolution keeps text and images looking sharper while giving you more usable desktop space.
4K provides even greater detail, but it isn't necessary for everyone. It makes more sense for people working with detailed imagery, video or other visual content, or anyone who particularly values very sharp text. For everyday office work, the extra cost might be better spent on an adjustable stand or better connectivity.
As a general target, 24 inches at 1080p or 24 to 27 inches at 1440p will suit many home and hybrid workers.
Ports and Cables: HDMI, DisplayPort and USB-C
Before choosing a monitor, check the ports on your laptop. There's little point finding the perfect display only to discover you can't easily connect it.
HDMI is one of the most straightforward options. If both your laptop and monitor have HDMI ports, you can usually connect them with a single cable. DisplayPort is also common on business monitors, although full-size DisplayPort connections are less common on laptops themselves. You might therefore need an adapter, dock or suitable cable.
USB-C can make things even tidier. If your laptop supports video output through USB-C and the monitor has compatible connectivity, one cable can potentially carry the display signal. Some monitors can also provide power back to a compatible laptop, reducing the number of cables across your desk.
The important point is that not every USB-C port supports video output, so check your laptop's specifications rather than assuming it will work.

If your setup needs an additional cable, hub or adapter, open-box accessories can help you complete it without replacing hardware unnecessarily.
If an older laptop is struggling to support the display setup or no longer suits your workload, it might also be worth looking at refurbished i7 laptops rather than building an increasingly complicated setup around ageing hardware.
Panel Type, Refresh Rate and Colour: What Actually Matters?
Monitor specifications can become technical very quickly, but most people only need to understand a few practical differences.
IPS panels are a strong all-round choice for office work. They generally provide good viewing angles and consistent colour, which is useful when you're sitting slightly off-centre or sharing the screen during a meeting.
VA panels typically offer stronger contrast, so darker images can look deeper. They're perfectly suitable for general work, although viewing angles can vary. OLED screens provide excellent contrast and image quality, but they're usually more expensive and unnecessary for a typical home-office setup.
Then there's refresh rate. A standard 60Hz monitor is fine for documents, email, web browsing and video calls. Moving to 75Hz or higher can make scrolling and general movement look smoother, but you don't need to chase very high refresh rates for ordinary productivity work.
If you edit photos, graphics or video professionally, colour accuracy deserves more attention. For everyone else, a good IPS office monitor is usually the simplest choice.
A matte screen finish is also worth considering if your desk is near a window or bright lighting, as it can help reduce distracting reflections.
Ergonomics: Don't Forget the Stand
A great monitor positioned badly can make your setup worse rather than better.
Ideally, the top of the monitor should sit roughly around eye level so you're not constantly looking down or tilting your head upwards. An adjustable stand makes this much easier because you can change the height, tilt and sometimes rotation of the screen.
If the included stand doesn't offer enough adjustment, a monitor arm is another option. It can free up desk space and gives you greater control over where the display sits.
Think about your laptop position too. If you're using its screen alongside the monitor, a laptop stand can raise it closer to the height of the second display. This reduces the amount of up-and-down movement when switching between screens.
These details aren't as exciting as resolution or screen size, but you'll notice them much more after eight hours at a desk.
How to Use Two Screens With Your Laptop
Once everything is connected, learning how to use two screens with your laptop is straightforward.
On Windows, go to Settings → System → Display. You should see both screens represented on the page. You can drag them into the same left-to-right arrangement as the physical screens on your desk, which ensures your cursor moves naturally between them.
You'll also have the option to extend or duplicate your display. Extend gives you additional desktop space across both screens and is the setting most people want. Duplicate shows the same content on both, which is more useful for presentations.
You can also choose which screen should be your primary display. That's generally where your taskbar and applications will open by default.
On macOS, go to System Settings → Displays to arrange the screens, choose the main display and adjust the available resolution settings.
Once you've completed your second monitor setup, spend a few minutes adjusting the physical position of both screens too. Software settings can't compensate for a monitor that's too high, too low or awkwardly positioned.
Refurbished Monitors: The Smart Upgrade
You don't necessarily need a brand-new display to build a good dual monitor setup for your laptop.
Business monitors from manufacturers such as Dell, HP and Lenovo regularly become available following corporate hardware refreshes. These screens were designed for day-to-day workplace use, making refurbished business monitors a natural fit for home offices and hybrid working.
Choosing refurbished can also make features such as larger displays, adjustable stands and better connectivity more accessible without moving into higher new-monitor prices. Our range of refurbished Dell monitors is a useful place to start if you're looking for a business-grade screen to pair with your existing laptop.
Just apply the same checks you would when buying new. Look at the screen size, resolution, available ports and stand adjustment rather than choosing based on price alone.
What Should Your Laptop Second Screen Look Like?
For most people, a good laptop second screen doesn't need complicated specifications. Start with a 24 to 27-inch display at 1080p or 1440p, check that its connections match your laptop and prioritise an adjustable stand that lets you position it comfortably. USB-C can make a hybrid setup particularly tidy, but HDMI remains perfectly practical.
Most importantly, choose around your desk and workload rather than buying the biggest screen available. A well-chosen refurbished monitor can give you the extra working space you need while keeping the overall upgrade cost sensible.
