Single-cable laptop users
If you prepare worksheets on a laptop and want to free its charger socket, look for a monitor that can carry video and supply enough charging power over USB-C. Check the laptop’s video and charging capabilities first.
Who this setup suits
Long-session reading-prep users
If you spend extended periods reviewing text, PDFs or lesson material, consider how the stand, screen format and desk position will work together. Display features do not replace suitable lighting and breaks.
Basic external-screen buyers
If you want more room for documents but do not need monitor-powered laptop charging, start with an input that matches your computer. HDMI or DisplayPort may meet that need without relying on USB-C video support.
What to check before buying
For reading-exercise preparation where sockets are scarce, decide whether freeing the laptop-charger socket is essential. Then check the video connection and how the screen will fit your desk.
| Concern | What to check | Who this matters to |
|---|---|---|
| Freeing a socket | Confirm USB-C video and charging support on the laptop, then compare its charging requirement with the monitor’s Power Delivery rating. | I want one cable for my laptop display and charging so I can put its separate charger away. Around 50% of consumers would put freeing that socket first. |
| Reading and document space | Check stand adjustment, glare and whether the screen size and format suit your desk and viewing distance. | When I review text for long periods, I need to position the screen comfortably and see enough of each document. For around 30% of consumers, that reading setup is the primary concern. |
| A compatible second screen | Match the computer’s video output to a monitor input and check which cable is needed. | I need extra display space, but charging the laptop through the monitor is not essential. A straightforward compatible connection would come first for around 20% of consumers. |
Mistakes to avoid
-
Assuming every USB-C port sends video
A USB-C connection limited to data or charging will not drive a monitor. Dell says the laptop needs DisplayPort Alt Mode or Thunderbolt for USB-C video.
Check the laptop manual before choosing a USB-C display connection. If the laptop cannot send video that way, check its other outputs and the monitor’s inputs.
-
Assuming a Power Delivery rating guarantees laptop charging
A monitor’s wattage alone does not establish whether a particular laptop accepts USB-C charging or whether its port can also send video.
Compare the monitor rating with the laptop maker’s charging requirements and confirm both charging and video support.
-
Expecting low-power USB-C to replace a laptop charger
Lenovo lists the ThinkVision E24-40 with 15W USB-C, while Dell’s P2425E and LG’s 27U730A-B list up to 90W. The lower rating should not be treated as sufficient for a laptop without checking that laptop’s requirements.
If freeing a socket is the goal, establish the laptop’s charging requirement before choosing a monitor.
Otherwise, you may still need to keep the laptop’s charger connected.
-
Relying on eye-comfort labels instead of screen placement
A display feature cannot correct an awkward screen height, glare or a poor viewing position.
Follow Health and Safety Executive guidance by placing the screen directly in front of you, with its top around eye level and the screen about an arm’s length away.
Brands to consider
These examples show different monitor features worth comparing; check the exact model rather than assuming every display from a brand has the same connections.
Dell
USB-C hub monitors for document-focused desks.
- Dell lists the P2425E with a 24-inch 16:10 WUXGA screen, adjustable stand and up to 90W Power Delivery.
- Dell says USB-C video still requires DisplayPort Alt Mode or Thunderbolt on the laptop.
Samsung
ViewFinity monitors with productivity and connection features.
- Samsung lists the 27-inch S60UD with QHD resolution, USB-C 90W charging and data, LAN and daisy-chain support.
- Check whether a 27-inch screen fits your desk position and preferred text size before choosing it for reading work.
LG
USB-C 4K monitors for buyers who also want laptop charging.
- LG lists the 27U730A-B with a 27-inch 4K IPS panel and USB-C 90W Power Delivery.
- Consider desk position and preferred text scaling rather than choosing 4K solely for its pixel count.
Lenovo
ThinkVision monitors with differing USB-C power ratings.
- Lenovo lists the ThinkVision E24-40 with a 23.8-inch FHD IPS panel and 15W USB-C.
- Confirm the laptop’s requirements before expecting that 15W connection to replace its charger.
BenQ
Home-office displays with stated eye-comfort features.
- BenQ describes the GW2490C as having low-blue-light and flicker-free features.
- Assess screen placement, lighting and breaks alongside those manufacturer-stated features.

Common questions
Can a USB-C monitor replace my laptop charger?
Yes, if the laptop accepts USB-C charging, can send video through DisplayPort Alt Mode or Thunderbolt, and the monitor supplies adequate power. Dell notes that a USB-C port limited to data or power will not send video, so check the laptop manual before relying on one cable.
Will a USB-C monitor remove every power cable from the desk?
No. A compatible hub monitor may replace the laptop’s separate charging connection, but the monitor itself still needs power.
How should I position a monitor for extended reading work?
Place the screen directly in front of you, with its top around eye level and the display about an arm’s length away, in line with Health and Safety Executive guidance. Check that your desk and stand allow that position before choosing a screen size.
Does regular reading-exercise preparation call for a workplace assessment?
It can if the work meets the display-screen-equipment conditions. The Health and Safety Executive says employers must assess the workstation for workers who use display screen equipment daily as normal work for continuous periods of an hour or more; the assessment covers the workstation, not just the monitor.
What should I do with an old monitor when replacing it?
Ask the retailer about its electrical-waste take-back route. GOV.UK says retailers must generally offer take-back of the same type of equipment when a customer buys a replacement, though qualifying retailers may use an alternative arrangement; check how to hand in the old monitor and whether collection involves a transport charge.
