Generic editorial illustration; the equipment does not depict the MSI Modern MD342CQP.
The MSI Modern MD342CQP is worth investigating if your desk serves both a work laptop and a personal computer. Its appeal is less about adding another wide screen and more about organising the display, charging and controls around the machines you already use.
The key is to plan the connections before ordering. A monitor can show two computers without automatically handling every aspect of switching between them. We have not tested the MD342CQP; this guide explains its documented features and the practical questions they raise.

The relevant features
MSI describes a 34-inch 3440 × 1440 curved VA display with KVM, picture-in-picture and picture-by-picture functions. Its USB-C connection supports DisplayPort Alternate Mode and up to 98W power delivery. The official specification lists up to 120Hz through DisplayPort or USB-C, while HDMI is listed at up to 100Hz at the native resolution. See MSI's specification table and feature overview.
These distinctions matter because your two computers may use different inputs. Plan each machine independently, including the connections needed for its keyboard and mouse data.
Draw two connection paths
Start with the work laptop. Identify its video capability, supported charging arrangement and any restrictions imposed by your employer. Then do the same for the personal computer. For each machine, your plan should show how the display signal reaches the monitor and how USB peripherals communicate with the computer.
The monitor's manual should be the reference for the KVM wiring and input assignments. Do not assume a video cable carries the keyboard connection simply because the picture appears. MSI lists a separate USB Type-B upstream connection as well as its USB-C connection; check the English user guide for the required arrangement.
| Connection to plan | Question to settle |
|---|---|
| Work laptop video | Does the selected port support the intended display mode? |
| Work laptop power | Does its documented charging support match the USB-C arrangement? |
| Personal computer video | Which input will it use, and what refresh rate does that path support? |
| Shared keyboard and mouse | Which upstream connection carries their data to each computer? |
Decide between switching and simultaneous viewing
If you use the work laptop during the day and the personal computer afterwards, switching the full screen may be the simplest arrangement. It gives each machine the entire display when it is active.
Picture-by-picture is more relevant when you need to see both computers at once. Consider how much room each task needs. A narrow section may work well for a monitoring window but be awkward for a detailed spreadsheet. Try sketching the two applications side by side before treating simultaneous viewing as essential.
Displaying a work computer next to a personal one does not itself transfer files between them. Keep your employer's normal handling rules in place and choose the arrangement for viewing and control convenience.
Match the refresh-rate expectation to the input
If the personal computer is used for gaming after work, check the intended output and cable against the documented limits. A headline refresh rate does not mean every input provides the same mode.
Once connected, inspect the operating system's display settings and confirm the selected resolution and refresh rate. Then test the activities you actually use: scrolling documents, moving windows and playing familiar games. Published response-time figures do not substitute for an assessment of how the image looks to you.
Check what your desk needs physically
Leave room to reach the controls you will use for switching. A beautifully hidden monitor connection can become inconvenient if you repeatedly need to unplug a cable. Position shared peripherals so that both the work and personal arrangements use the same comfortable area of the desk.
For the wider screen decision, see our home-office monitor guide. Use our desk cable-management guide to organise the two upstream paths without confusing them. A simple label at each computer end can save time when diagnosing a connection problem.
Who should consider the MD342CQP?
It is a sensible candidate for a shared work-and-personal desk when the documented switching arrangement matches both computers. Compare a simpler monitor if you use only one machine and do not value the additional connectivity. Compare an external switching setup if you already own a display you like.

Frequently asked questions
Does KVM mean I can skip all extra cables?
No. Each computer still needs the required video and data paths. Check the manufacturer's connection diagram and the contents of the box, then budget for any missing cables.
Should I replace a working external KVM?
Only if the new arrangement solves a problem you care about. If your current switching is reliable, compare the monitor on display quality, fit and complete cost before paying mainly to remove one small box.
