There's something about a second screen that just makes everything easier. You stop flipping between windows, keep references open beside your work, and actually see more of what you're doing at once. The good news? You don't need a heavy monitor or a desk to get it. A Catsights portable display turns your laptop into a full dual-screen workstation that fits in a bag.
Here's how to build one.
Why two screens
If you've never worked this way, it's hard to describe how much it helps until you try it. A few of the big wins:
- Reference beside your work — keep a spec sheet, notes, or a tutorial open on one screen while you write or edit on the other.
- Full-screen previews without losing your tools — see the finished result big, while the toolbar and palettes stay visible.
- Way less alt-tabbing — when both apps are visible at once, you just look instead of constantly switching.
Most people feel the difference within the first hour.
The core setup
The basic layout is simple: laptop on one side, Catsights display on the other, connected with a single USB-C cable. That one cable handles video, power, and touch, so there's nothing else to plug in.
A few small things make it feel right:
- Put both screens at eye level. A second screen that's too low or off to the side gets ignored. Line the panels up so you're not craning your neck.
- For travel, keep it light. A compact stand does the job, but honestly, a stack of books works perfectly too. If you're setting up in a coffee shop or a hotel room, you use what's around you.
- Match the arrangement to your desk. Put the Catsights display where it physically is — left, right, or above — so moving your cursor between screens feels natural.
Set up your software
Once the hardware's in place, a couple of tweaks make the two screens work like one.
- On macOS, Mission Control lets you create separate Spaces. Put email and chat on one screen, your main work on the other — or give each Space its own task and jump between them with a swipe.
- On Windows, Snap Layouts handles the window arranging. Hover over a window's maximize button, pick a layout, and Windows snaps the windows into place. Perfect for side-by-side documents or a browser next to an editor.
These take a couple of minutes to set up, and they save you that time every single day after.
Cable management for travel
A single USB-C cable keeps the whole setup surprisingly clean — no power brick, no dock, no spaghetti behind the desk. It's one of the nicest parts of working this way.
For longer sessions, grab a USB-C power adapter and plug it into the hub's power-input port. The display runs off the adapter, and the hub can charge your laptop at the same time — reverse charging up to 45W. One adapter keeps both devices topped up, so you can work all day without hunting for a second outlet.
Putting it together
Two screens, one cable, one bag. It takes about ten minutes to set up, and once you've done it, going back to a single laptop screen feels cramped. Whether it's for editing, coding, writing, or just keeping your messages always in view — a portable dual-screen setup is one of those upgrades you'll wonder how you lived without.
