One screen is a bottleneck. As a freelancer, your working day is reference material on one side and actual work on the other — brief on the left, draft on the right; spreadsheet here, invoice there. A portable monitor gives you that second screen anywhere: client offices, co-working spaces, cafés, trains.
This guide compares the three portable monitors UK freelancers actually buy: all 15.6-inch, all Full HD, all designed to live in a laptop bag. They are judged on what matters for mobile work — single-cable setup, weight and bulk, the stand situation, and connectivity.
How we judged them
- Single-cable USB-C — the whole point of a portable monitor. One cable for video and power, no brick in your bag.
- Portability — weight and thickness. If it doesn’t fit comfortably in your laptop bag, you won’t carry it.
- The stand — the most underrated feature. A monitor you can’t prop up reliably is useless; built-in stands beat origami covers.
- Connectivity — USB-C is standard, but an HDMI option matters if your laptop’s USB-C doesn’t carry video.
- Screen quality — all three are Full HD IPS panels, which is the right baseline for text and spreadsheets on the move.

Best value: ASUS ZenScreen MB166C
The ZenScreen MB166C is the default portable monitor for a reason: 15.6-inch Full HD IPS, a single USB-C cable for video and power, flicker-free panel with a blue-light filter for long days, and a smart cover that doubles as a stand — all in the budget tier.
Why freelancers love it: the setup is genuinely one cable. Plug it into your laptop’s USB-C port and you have a second screen in seconds — no power brick, no configuration. The blue-light filter and flicker-free panel matter more than they sound when you are staring at text for eight hours. The smart cover protects the screen in your bag and folds into a stand on a desk. For café and co-working work, this is the formula that works.
The honest drawbacks: the cover-stand is functional, not great — it works on a flat desk and nowhere else, and it only gives you one or two usable angles. There is no HDMI input, so if your laptop’s USB-C port doesn’t carry video (check before you buy), this monitor won’t work for you. And the built-in speakers on portable monitors are universally an afterthought — use headphones.
Verdict: the rational default. The most popular portable monitor in its class, and the one to beat for mobile dual-screen work.

The ViewSonic VG1655 takes the same 15.6-inch Full HD IPS formula and fixes the stand problem: it has a proper built-in stand with adjustable tilt, dual speakers, two USB-C ports with 60W power delivery, and a mini-HDMI input — which makes it the most versatile of the three.
Why freelancers love it: the built-in stand is the headline. It props the monitor at a proper viewing angle on any desk, in portrait or landscape, with no origami cover to fight with. The mini-HDMI input means it works with older laptops, desktops, and even consoles — if your laptop’s USB-C doesn’t carry video, this is your safety net. Two-way USB-C power delivery can charge the monitor from your laptop or pass power through to it. The metal build feels like it will survive years of bag travel.
The honest drawbacks: it is the mid-range pick on price, and you are paying for versatility you might not need if your laptop has a proper video-capable USB-C port. The speakers exist; they are better than nothing for a quick call, and that is the kindest thing to say about them.
Verdict: buy it if you want one monitor that works everywhere — modern laptop over USB-C today, older hardware over HDMI tomorrow, proper stand wherever you land.

The ZenScreen MB16AC is the earlier generation of the ASUS formula — 15.6-inch Full HD IPS, single-cable USB-C, eye-care panel — and it remains widely available. Functionally it is very close to the MB166C: same screen size, same resolution, same one-cable setup.
Why freelancers love it: it is the same proven concept as the MB166C. In practice, the buying advice is simple: check the live prices of both ASUS models on the day and buy whichever is cheaper. They do the same job — a second screen in your bag, one cable, no fuss.
The honest drawbacks: it is the older design, so when prices are equal the MB166C is the fresher pick. Like the MB166C it is USB-C only, so the same warning applies: confirm your laptop’s USB-C port carries video before buying. And the cover-stand is the same origami compromise.
Verdict: the smart fallback. If the MB166C is out of stock or priced higher when you check, this is the same job done well.

Which one should you buy?
- Maximum portability, minimum fuss → ASUS ZenScreen MB166C. One cable, in the bag, done.
- One monitor for every situation → ViewSonic VG1655. The stand and HDMI input cover the cases the ASUS models don’t.
- Best price on the day → compare the two ASUS models live and take the cheaper one. They are functionally interchangeable.
- Older laptop without video-capable USB-C → ViewSonic VG1655. The mini-HDMI input is the only one of the three that helps you.
Buying advice: check your USB-C port first
This is the step people skip: not every USB-C port carries video. Your laptop’s USB-C port needs to support DisplayPort Alt Mode (sometimes labelled with a small monitor icon next to the port) for the single-cable USB-C monitors to work. Check your laptop’s specs before ordering — if your port is data-and-charging only, you need the ViewSonic’s HDMI input or a docking station.
Two more practical notes. First, a portable monitor draws power from your laptop over USB-C, so expect your battery to drain faster — fine for desk work near a socket, worth knowing on a train. Second, these panels are designed for indoor use: fine in a café or a shaded spot, but you’ll struggle in direct sunlight — for outdoor work in summer, sit in the shade.
Buy from a seller with free returns (Amazon UK offers them on all three above). Test the monitor with your actual laptop, your actual cables, within the return window — compatibility surprises are the main reason these get returned.
Frequently asked questions
Will a portable monitor work with my laptop?
If your laptop has a USB-C port that supports video output (DisplayPort Alt Mode), yes — one cable handles video and power. If it doesn’t, choose a model with HDMI input (the ViewSonic VG1655 here) and connect over HDMI, with USB-C or a separate cable for power. When in doubt, check your laptop manufacturer’s specs page for the port details.
Can my laptop power the monitor, or do I need a plug?
Your laptop can power it over the same USB-C cable — that’s the standard setup. The trade-off is battery life: the monitor draws a few watts continuously, so a full working day on battery alone is optimistic. Near a socket, it’s a non-issue.
Is 15.6 inches big enough for a second screen?
For the jobs a second screen does — reference documents, chat, email, preview windows — yes. It matches most laptop screens, so windows move between the two without resizing weirdness. If you want a big canvas for design or video timelines, you want a desk monitor, not a portable one.
Do I need a touchscreen portable monitor?
Probably not. Touchscreens cost more, drain more battery, and add glossy reflections. Unless you sketch, annotate, or present with touch, skip it — the money is better spent on the stand and panel quality.
