The Best Portable Monitors for Working Anywhere
A second screen is the most cost-effective productivity upgrade most traveling professionals never make. A good portable monitor runs off a single USB-C cable, stays bright enough to read in a sunlit lobby, and folds flat into a laptop bag. We looked at panel quality, connectivity, weight, and the quality of the built-in stand — the part most cheap units get wrong. Here are the picks worth the bag space.
Editor's pick · Best overall
Espresso Displays 17 Pro
Espresso
A 4K touchscreen in a machined aluminium shell that is genuinely hard to distinguish from a premium laptop lid. At 17 inches it delivers real estate that justifies the bag space, and the magnetic modular stand system means setup on any desk — hotel, airport club, or boardroom — takes seconds.
Ideal for: Executives who want the closest thing to a desktop-grade second screen in carry-on luggage.

What to look for
Single-cable USB-C
One USB-C cable carrying power, video, and touch is the whole point. Check that your laptop's port supports DisplayPort Alt Mode.
Brightness
Aim for higher nits if you work in bright rooms. Dim panels are the most common regret with budget units.
Stand and protection
A sturdy kickstand or a folio that doubles as a stand keeps the screen upright; a built-in cover protects the panel in transit.
Weight and thickness
Under ~2 lbs and slim enough to slide beside a laptop is the difference between bringing it and leaving it home.
The picks
Espresso Displays 17 Pro
Espresso
A 4K touchscreen in a machined aluminium shell that is genuinely hard to distinguish from a premium laptop lid. At 17 inches it delivers real estate that justifies the bag space, and the magnetic modular stand system means setup on any desk — hotel, airport club, or boardroom — takes seconds.
Pros
- 4K IPS panel with 100% DCI-P3 coverage reads accurately in colour-critical work
- Ultra-thin aluminium build feels purpose-built, not accessory-grade
- Magnetic Stand+ Pro included — no separate folio fumbling
- Responsive touch input doubles as a signing and annotation surface
Cons
- 17-inch footprint is a tight fit alongside a 16-inch laptop in a single sleeve
- Full feature set (pen, second stand orientation) requires additional Espresso accessories
- Heavier than 15-inch alternatives at 1.1 kg
Ideal for: Executives who want the closest thing to a desktop-grade second screen in carry-on luggage.
LG gram +view 16 (2024)
LG
LG engineered this panel specifically to pair with its gram laptop line, and the result is one of the most cohesive portable-monitor experiences available. The 16:10 WQXGA panel at 99% DCI-P3 is sharp enough that text renders without compromise, and the folio cover functions as a stable portrait-or-landscape stand with no adjustment required.
Pros
- WQXGA (2560x1600) 16:10 panel — noticeably sharper than 1080p alternatives
- Folio cover doubles as a fully stable landscape and portrait stand
- 1.45 lbs slides beside a laptop in any premium sleeve without bulk
- Auto-pivot detects orientation and rotates the display automatically
Cons
- Single USB-C port means no pass-through charging to the host laptop
- 60 Hz refresh rate — adequate for productivity, not for anything motion-intensive
- Matte coating can soften perceived contrast in very dark content
Ideal for: Executives who travel with a MacBook or Windows ultrabook and want a seamlessly matched second display.
Espresso Displays 15
Espresso
The original flagship from Espresso remains the most refined 15-inch portable display on the market. Aeronautical-grade aluminium, a single USB-C cable, and a touchscreen that responds accurately make it the quiet default for anyone who values build quality over spec-sheet numbers.
Pros
- Strikingly thin — stacks against a laptop lid without adding perceived bulk
- Touch input works without drivers on macOS and Windows
- Single-cable USB-C operation with no external power required
- Premium aluminium construction holds up to daily travel without flex
Cons
- 1080p resolution is the one concession to thinness — the 17 Pro renders sharper
- Best ergonomic positioning requires the sold-separately Espresso Stand+
Ideal for: Frequent travellers who want the most packable premium touchscreen display and prioritise weight and build over maximum resolution.
HP Series 5 Pro 514pn
HP
HP's professional-tier portable is the understated choice for executives who want unimpeachable colour accuracy without the design-forward premium. The aluminium unibody at 1.4 lbs is exceptionally rigid, the 2560x1600 16:10 panel covers 100% sRGB and AdobeRGB simultaneously, and a single USB-C cable delivers up to 65W of pass-through charging to the host machine.
Pros
- 100% sRGB and AdobeRGB colour gamut — accurate out of the box for document and presentation work
- 65W USB-C pass-through charges a laptop while in use
- 14.3-inch size is the most carry-on-friendly footprint in this class
- HP Sure View privacy coating available — relevant for open-plan offices and flights
Cons
- 14.3-inch panel is compact — executives who want expansive real estate should step up to 16 or 17 inches
- Integrated stand offers limited angle adjustment compared to magnetic accessory systems
- HP branding reads more enterprise than executive lifestyle
Ideal for: Road warriors on back-to-back flights who need a compact, colour-accurate display and want pass-through charging to keep the laptop topped up.
Who this guide is not for
If your laptop lacks a USB-C port with video output, you'll need an adapter and a separate power source — at that point a model with HDMI input and its own power brick makes more sense.
Frequently asked
If your laptop has a USB-C port that supports DisplayPort Alt Mode, a single cable handles power and video. Older laptops may need HDMI plus a separate power cable.
