People switching between two computers
If the keyboard and mouse need to follow the active computer, check how the monitor switches peripherals, not just whether it has two video inputs. BenQ lists a KVM switch for its PD2705U.
Who this monitor choice affects
Detail-focused diagram makers
Fine labels, line work and colour-coded diagrams make native resolution and the colour space required by the intended output worth checking. The 4K models described by Dell, BenQ and LG offer different stated display and connection features; a colour-coverage figure alone does not establish the result in every application.
Laptop-first desk sharers
If one laptop is normally connected, check whether its USB-C port can carry video and whether the monitor supplies enough charging power. An adjustable stand also helps each person position the screen; the Health and Safety Executive advises placing its top around eye level and the screen about an arm’s length away.
What matters when choosing
Decide whether switching between computers or connecting one laptop is the main job, then check diagram detail and how the display will fit the desk.
| Concern | What to check | Who this matters to |
|---|---|---|
| Switching computers and peripherals | Confirm a KVM switch, the USB upstream connections and how the keyboard and mouse follow the selected computer. | If I move between two computers, I want my keyboard and mouse to move with my work rather than reconnecting them. Around 29% of consumers put that shared-peripheral need first. |
| Diagram detail and colour | Check native 3840 × 2160 resolution and whether the stated colour space matches the intended output. | Small labels and colour-coded structures need to remain distinguishable in my diagrams; around 29% of consumers prioritise detail and colour interpretation. |
| Fit and screen position | Check stand adjustment and desk depth. The Health and Safety Executive advises a screen top around eye level and a viewing distance of about an arm’s length. | When different people use the desk, I need room to reposition the screen for each person. Around 24% of consumers place workstation fit first. |
| One-cable laptop connection | Confirm USB-C video support, the laptop’s charging requirement and the cable specified for the monitor. | I usually connect one laptop and want a compatible display, data and charging connection without separate desk cables; around 18% of consumers make that their primary need. |
Checks before you buy

Several video inputs do not establish KVM switching
Two computers may both connect to a screen without the keyboard and mouse switching between them. BenQ explicitly lists a KVM switch for the PD2705U.
Check the exact model’s KVM function, USB upstream ports and switching method if both computers must use the same peripherals.
Otherwise, that workflow may require a separate KVM switch or reconnecting peripherals.
-
A USB-C socket does not settle laptop compatibility
BenQ specifies 65 W USB-C power delivery for the PD2705U, while LG specifies up to 90 W for the 27UP850K-W. Neither figure establishes what a particular laptop can receive or whether its port carries video.
Check the laptop’s USB-C video capability and charging requirement against the exact monitor and the cable it requires.
A separate charger, dock or compatible cable may still be needed for the intended setup.
-
Stand adjustment does not replace desk setup
Even an adjustable screen needs space for a suitable viewing position. The Health and Safety Executive advises placing the top of the screen around eye level and the display about an arm’s length away.
Measure the usable desk depth and check the position for each person who uses it before deciding whether the supplied stand will work.
-
A similar model name can hide a different monitor
Resolution, connections and stand features can differ between models in the same brand’s range. For example, Dell’s P2425H is a different model from the U2725QE discussed here.

Relevant brands for reference
BenQ
The Creative Pro PD2705U is a 27-inch 4K IPS option for diagram work where switching between computers matters.
- BenQ specifies a KVM switch, height and pivot adjustment, 99% sRGB and 99% Rec.709 coverage, and 65 W USB-C power delivery for the PD2705U.
- Check whether 65 W meets the laptop’s charging needs. BenQ’s colour-coverage figures are model specifications, not a guarantee of results in every colour-managed workflow.
Dell
The UltraSharp U2725QE is a 27-inch 4K hub-monitor option for a desk centred on one primary computer.
- Dell lists an IPS Black panel, a 120 Hz refresh rate and height and pivot adjustment for this model.
- Confirm the exact connections and peripheral-switching behaviour needed at the shared desk rather than assuming a hub connection performs a KVM’s job.
LG
The 27UP850K-W is a 27-inch 4K IPS option for a desk normally connected to one USB-C laptop.
- LG lists USB-C display and data functions, charging up to 90 W, and height, pivot and tilt adjustment for this model.
- Check laptop and cable compatibility, and confirm peripheral-switching requirements separately if two computers will share the desk.
Joybuy monitors for diagram work
These monitors offer different screen sizes and connection options for diagram work at a shared desk. Check the exact model against your computer and peripheral setup; a USB-C connection or multiple inputs alone do not establish two-computer switching.

BenQ MA270UP 27-inch 4K USB-C monitor
Consider this for a one-laptop diagram desk where screen positioning and USB-C connectivity matter. The named variant has a Nano Glossy IPS display and height-adjustable stand; check laptop video and charging compatibility, and confirm peripheral switching separately if two computers will be connected.
No image available
MSI MD272UPSW 27-inch 4K Smart Monitor with Google TV
This is worth checking if two-device control is central to the shared desk. The named IPS variant includes Multi-Control and USB-C 65 W; confirm how Multi-Control works with your computers and peripherals, and whether the laptop supports the required video connection and charging level.
No image available
LG 27UP650K 27-inch 4K IPS monitor
Consider this for diagram work where a 27-inch display and adjustable positioning take priority. The named variant has HDMI and DisplayPort connections and stated DCI-P3 95% coverage; check the required laptop connection and peripheral-sharing workflow before choosing it for a one-cable or two-computer desk.

Dahua 32-inch curved 4K OLED gaming monitor
This larger display is an option only if the shared desk can accommodate its 32-inch curved screen. The named variant specifies 165 Hz, DCI-P3 99%, USB-C 65 W and a USB hub; check viewing position, laptop compatibility and any required keyboard-and-mouse switching separately.
No image available
MSI MAG 275UPD E14 27-inch 4K gaming monitor
Consider this for a 27-inch 4K diagram workspace if its connection options suit the desk. The named variant specifies a 144 Hz UHD mode and an FHD 288 Hz dual mode; check the colour target and whether your laptop or shared peripherals need connections beyond those established for this model.
Frequently asked questions
Is a 27-inch 4K monitor a sensible starting point for science diagrams?
Yes, if the shared desk has room to position it properly. The 27-inch 4K IPS models specified by Dell, BenQ and LG provide options with adjustable stands, but screen size alone does not settle workstation fit; the Health and Safety Executive advises a screen top around eye level and a viewing distance of about an arm’s length.
Can one USB-C cable carry the picture and charge my laptop?
It can when the laptop, monitor and cable support the required video and charging functions. BenQ specifies 65 W USB-C power delivery for the PD2705U, while LG specifies display, data and charging up to 90 W for the 27UP850K-W; compare those limits with your laptop’s requirements.
Does a USB-C monitor switch a keyboard and mouse between two computers?
Not necessarily: USB-C charging and two-computer peripheral switching are different functions. Check the exact model’s KVM or other switching specification and port arrangement; BenQ lists a KVM switch for the PD2705U.
What can I do with an old monitor?
Consider reuse or an electricals recycling collection point rather than treating the monitor as ordinary waste. Recycle Your Electricals says items with a plug, battery or cable can be reused or recycled and offers a way to find local collection options.
