Choose a fixed monitor when you mainly work at one desk and need a larger display with a stable, adjustable position. Choose a portable monitor when you move between workspaces, but confirm that your laptop can send video through USB-C or plan for HDMI video and separate power where required.
For people working mainly at one home desk who need documents, calls and applications visible together. Prioritise monitor size, stand adjustment, video inputs and whether the desk can accommodate the screen. Health and Safety Executive guidance highlights display position as a workstation consideration.
For people who need a compact second screen across home, shared offices or travel. Check for USB-C DisplayPort Alt Mode, or plan for HDMI video and a separate power connection where relevant. Microsoft Learn and portable-monitor manufacturers note that USB-C video capability depends on the specific port.
For people with limited desk surface who may want to move a compatible monitor off its supplied stand. Confirm VESA mounting, monitor weight, arm capacity, desk-edge thickness and clearance beneath the desk before choosing an arm.
Start with the connection your computer can make, then decide whether a fixed or portable screen suits the workspace. Check mounting and desk dimensions before adding an arm or choosing a larger display.
| Priority | What to check | Your needs |
|---|---|---|
| Computer connection | Identify the computer’s HDMI, DisplayPort, Thunderbolt or USB-C video output. Match it to the monitor input and confirm supported external-display count and resolution. USB-C shape alone does not confirm video output. | I need a connection that works with my exact laptop or desktop, rather than relying on a USB-C cable, dock or adapter that cannot carry a display signal. |
| Fixed or portable setup | Measure the available desk area for a fixed screen. For a portable monitor, compare weight, stand arrangement, video inputs and the power route needed for the intended connection. | I want the second screen to suit where I actually work: a repeatable desk setup at home, or a display I can carry between locations. |
| Screen positioning | Compare height, tilt, swivel and pivot functions on the supplied stand. For an arm, match VESA mounting and monitor weight, then measure the desk edge and clear space below the clamp point. | My screen, keyboard and mouse need to fit the available desk arrangement. The Health and Safety Executive advises positioning the top of the screen around eye level and roughly an arm’s length away. |
USB-C is a connector format rather than proof of video output. A USB-C monitor, dock or adapter may not provide a display signal if the computer lacks the required DisplayPort Alt Mode, Thunderbolt or USB4 capability.
Check the exact computer specification for supported video outputs, then match the output to the monitor input. Microsoft Learn and Apple Support both advise checking the relevant video capability rather than relying on connector shape alone.
A portable display may use one USB-C cable for video and power only when the host device supports the necessary connection. An HDMI fallback can require a separate USB-C or mains power connection.
Confirm whether the laptop USB-C port supports DisplayPort Alt Mode and whether the intended charger meets the monitor’s stated requirements. If not, select a model with HDMI input and plan its separate power connection.
Screen size does not establish monitor weight, VESA mounting compatibility, desk-clamp fit or the clearance needed under the desk. A mismatch can prevent installation.
Compare the exact monitor weight and VESA pattern with the arm documentation, then measure the desk edge and check for drawers, cable trays or other obstructions below the clamp point.
A larger screen can still be awkward in a constrained workspace if its stand cannot be positioned in relation to the laptop, keyboard and mouse.
Measure usable desk depth and width first. For regular desk work, compare stand height range, tilt, swivel and pivot, or confirm an arm setup, before making screen size or resolution the deciding factor.
Dell has fixed monitors and USB-C hub-monitor options for desk-based setups, including models with adjustable stands and, on selected models, USB-C power delivery.
ThinkVision includes portable-monitor options for hybrid workers who need a compact second screen with compatible USB-C laptop connections.
ASUS ZenScreen portable displays can suit users who need USB-C mobility while retaining an HDMI-based fallback connection on selected models.
Ergotron offers monitor-arm options for fixed displays where reclaiming desk surface and repositioning the screen are priorities.
Joybuy options for adding a second screen to a home or hybrid work setup, including fixed desk monitors and portable displays.

A 23.8-inch option for hybrid or hot-desk work where a larger second screen and flexible placement are useful.
Stated features include IPS, USB-C, HDMI, 60 W USB-C power delivery, a kickstand, C-clamp arm and partition hook kit. One-cable USB-C video requires a computer with DisplayPort Alt Mode; check that the supplied mounting accessories suit the intended desk or divider.

A fixed desk-monitor route for documents, calls and everyday home-office work.
This 24-inch IPS monitor states 1920 × 1080 resolution, 100 Hz, and HDMI, DisplayPort, USB-C and VGA connections, with height, tilt and swivel adjustment. Confirm whether its USB-C connection supports video, laptop charging or both for the exact setup.
No image available
A fixed-screen option for viewing documents and applications side by side at a desk.
The stated 29-inch 21:9 IPS panel has 2560 × 1080 resolution, HDMI and DisplayPort inputs, and VESA 100 × 100 mm mounting. Allow for the stated 688.5 mm monitor width; the supplied stand is stated to adjust for tilt.

A portable 15.6-inch display for recurring hybrid work and travel between locations.
It states an IPS panel, built-in battery, Smart Case stand, USB-C and Micro-HDMI connectivity, and a weight of about 860 g. USB-C video-and-power use depends on compatible output and power from the source device.

A lightweight portable second-screen route for workers who prioritise a compatible one-cable laptop setup.
This 15.6-inch display states a Full HD IPS panel, 780 g weight, 11.8 mm thickness and USB-C DisplayPort Alt Mode connection. HDMI is not supported on this SKU, so it needs a compatible USB-C video output and sufficient host-device power.
Not if the laptop and monitor already share a video connection, such as HDMI-to-HDMI or DisplayPort-to-DisplayPort. If the connectors differ, choose a cable or adapter that supports the required video standard; a USB-C connector alone does not prove that the laptop can output video.
No. A one-cable portable-monitor setup requires the laptop USB-C port to support video output, commonly DisplayPort Alt Mode. ASUS advises checking DP Alt Mode for USB-C use of the MB16FC, while Lenovo specifies DP 1.2 Alt Mode and PD 2.0 for the ThinkVision M14 setup.
Use this route when the laptop lacks USB-C DisplayPort Alt Mode but the portable monitor has HDMI input and a separate power-capable USB-C input. ASUS states that the MB16FC can use HDMI for video and USB-C DC-in for power in that arrangement.
No universal answer applies. Apple says the number of external displays supported at the same time depends on the exact Mac model and on the connected displays’ resolution and refresh rate. Check the technical specification for the specific Mac before buying a dock or multi-display adapter.
Check that the monitor has a compatible VESA mounting interface, that its actual weight is within the arm’s supported range, and that the desk edge and underside meet the installation requirements. Ergotron lists the LX Pro with VESA MIS-D support, a 1.8–10.0 kg capacity, a 10–60 mm desk-edge range and a 70 mm under-desk clearance requirement.
