Frequent spreadsheet cross-checkers
If you regularly compare cells or formulas with a PDF, document or web page, prioritise readable text and the number of rows you can see without repeatedly scrolling.
Who needs a second screen?
Mobile workers with USB-C laptops
A portable screen can travel with your laptop, but a USB-C socket alone does not establish that the laptop can send video through it. Check the specific port and monitor connection method.
Occasional reference-checking users
If you only compare documents and spreadsheets from time to time, consider whether a Full HD screen gives you enough working space before prioritising more pixels. Its stand and connection still need to suit your desk and laptop.
What should you check before buying?
Start with the rows and text you need to see, then check the connection to your laptop and where the monitor will stand. A larger diagonal does not, by itself, tell you how much vertical spreadsheet space you will have.
| Concern | What to check | Who this matters to |
|---|---|---|
| Text and vertical workspace | Compare native resolution, aspect ratio and the visible rows at your usual display scaling. Lenovo UK lists the ThinkVision M14d at 2240 × 1400; Dell UK lists the P1425 at 1920 × 1200. | When matching spreadsheet entries against a source document, I want headings and more rows in view without making text uncomfortable to read. Around 42% of consumers put that workspace need first. |
| Laptop connection | Confirm whether the laptop’s USB-C port outputs video and whether the monitor requires DisplayPort Alt Mode or a different connection. Check software requirements for any DisplayLink mode. | If I move between desks, I need the second screen to connect reliably without discovering that my laptop port only handles data or charging. For around 33% of consumers, connection compatibility is the primary concern. |
| Travel and desk setup | Check packed size, weight, the included stand and its adjustment against the desks and bag you use. | On a small or changing desk, I need the screen to fit beside my laptop and remain at a usable angle. Ease of carrying and positioning comes first for around 25% of consumers. |
Common buying mistakes
-
Assuming every USB-C port carries video
A monitor that uses DisplayPort Alt Mode needs a compatible video-capable laptop port. ASUS support also notes that a DisplayLink connection can require software installation.
Check the laptop’s port specification and the exact monitor connection mode before ordering.
-
Choosing by diagonal size alone
A 15.6-inch 1920 × 1080 screen has fewer vertical pixels than a 14-inch 1920 × 1200 or 2240 × 1400 screen. The space you can use also depends on display scaling.
Compare aspect ratio and native resolution alongside size, using the scaling you expect to use for reading.
-
Assuming the monitor will charge the laptop
Power pass-through differs between models. Lenovo UK states 65 W pass-through for the ThinkVision M14d, while Dell UK lists no power delivery for the P1425.
Compare any stated pass-through rating with your laptop’s charging requirement rather than treating a USB-C video connection as a charging guarantee.
Relevant brands to consider
Lenovo
The ThinkVision M14d is a compact 14-inch option for readers considering a higher-resolution 16:10 workspace.
- Lenovo UK specifies a 2240 × 1400 IPS panel, 600 g weight, two USB-C ports with DisplayPort 1.2 Alt Mode and an adjustable stand.
- Check the laptop’s USB-C video output. Its stated 65 W power pass-through also needs to be compared with the laptop’s charging requirement.
Dell
The Pro 14 Plus P1425 offers a 14-inch 16:10 screen for document and spreadsheet reference work.
- Dell UK lists a 1920 × 1200 IPS anti-glare panel and an included tilt stand.
- It has fewer pixels than the Lenovo ThinkVision M14d, and Dell UK lists no power delivery for the P1425.
ASUS
The ZenScreen MB16ACE is a 15.6-inch option for buyers considering a wider Full HD screen rather than a 16:10 layout.
- ASUS UK specifies a 1920 × 1080 IPS anti-glare panel, USB-C DisplayPort Alt Mode and an included smart case.
- Its 16:9 format has fewer vertical pixels than the 16:10 models above. Check driver requirements if you intend to use its DisplayLink connection path.
Portable monitors on Joybuy
These portable monitors offer different screen sizes and stated display formats for keeping reference material beside a spreadsheet. Compare each model’s connections and desk setup with your laptop before choosing; the products here are not a substitute for those checks.

ASUS ZenScreen Go MB16AHP FHD
Consider this FHD model if you want a separate screen for source material while working in a spreadsheet. Check its connection options and how you will position it beside your laptop.
No image available
ASUS ZenScreen MB166CR FHD
For reference checking away from your usual desk, confirm that its video connection works with your laptop and that its stand arrangement suits the space available.

UPERFECT 14-inch 60 Hz touchscreen with 180° stand
Touch input may matter if you use it alongside spreadsheet checks. The product title specifies a 14-inch touchscreen, 60 Hz refresh rate, VESA compatibility and an adjustable 180° stand; confirm the video connection your laptop can provide.
No image available
UPERFECT 18.4-inch 4K QLED portable monitor
Consider its larger screen if you have room beside your laptop, while checking that it fits your travel setup. The product title states 3840 × 2160 resolution, USB-C and Mini HDMI connections, an integrated mount and VESA compatibility; confirm the connection mode you need.
No image available
UPERFECT 16-inch 2K 144 Hz QLED portable monitor
Its stated 2560 × 1600 resolution and 16:10 format are relevant if vertical spreadsheet space is a priority, though your chosen scaling will affect how much you see. The product title also states 144 Hz, Mini HDMI, Type-C and VESA compatibility; check the Type-C video mode and stand arrangement for your setup.
Frequently asked questions
Will any USB-C laptop work with a USB-C portable monitor?
No: a USB-C connector does not necessarily carry video. For a monitor using DisplayPort Alt Mode, check that the laptop’s specific USB-C port supports compatible video output; a DisplayLink connection may require a driver instead.
Does 16:10 help when checking spreadsheet references?
A 16:10 screen can give you more vertical pixels than a 16:9 screen at comparable horizontal resolutions. For example, Dell UK lists the P1425 at 1920 × 1200, while ASUS UK lists the MB16ACE at 1920 × 1080. Check your preferred display scaling before deciding how useful that difference will be.
What should I do with a portable monitor I no longer use?
Check electrical-equipment collection or take-back options rather than putting the monitor in general waste. GOV.UK describes UK waste electrical and electronic equipment arrangements for recovery, reuse and recycling; your retailer or local authority can tell you which collection route is available.
