A USB-C monitor can free the socket used by a laptop charger if the laptop supports charging and video through the intended port, and the monitor supplies enough power; the monitor still needs its own mains connection. Compare the laptop maker's recommended charging wattage with the monitor's USB Power Delivery rating, then check the cable, peripheral ports and audio route before choosing a 65 W or 90 W model.
If you prepare tracks on a laptop, a monitor that carries video, data and sufficient charging through one USB-C connection could let you leave the laptop charger unplugged. Check the laptop's recommended wattage and port capabilities before relying on that arrangement.
If you connect storage, a keyboard, a controller or other USB devices while arranging tracks, a monitor hub may reduce the need for a separate dock. Count the downstream ports and check their connectors and power capabilities against your devices.
If desk space is tight, compare the physical fit and stand adjustments alongside charging. The 24-inch, 16:10 Dell P2425E and 27-inch, 4K LG 27UP850K-W offer different screen formats; resolution alone does not settle which fits your workspace.
For consumers preparing rehearsal tracks with few available sockets, start with the need that matters most: freeing the laptop charger socket, connecting peripherals or fitting the desk.
| Concern | What to check | Who this matters to |
|---|---|---|
| Laptop charging and video | Compare USB Power Delivery wattage with the laptop maker's recommendation; confirm video output and charging through the intended laptop port and cable. | If my laptop charger occupies a socket needed for other equipment, I want the monitor connection to carry video and enough charging power. Around 50% of consumers put freeing that charger socket first. |
| Peripheral connections | Count the required downstream USB-A and USB-C ports; check device power needs and the intended audio connection. | When I organise tracks with several connected devices, avoiding a separate powered hub matters more than screen format. Roughly 30% of consumers make peripheral consolidation their primary concern. |
| Screen and desk fit | Measure desk space, compare screen formats and stand adjustment, and confirm the laptop can output the chosen display mode. | A shared or cramped desk makes the monitor's footprint and position my deciding factors. About 20% of consumers prioritise screen and desk fit. |
USB-C describes the connector, not a guaranteed charging wattage or video capability. LG specifies up to 90 W for the 27UP850K-W, while BenQ specifies 65 W for the GW2790QT; neither figure establishes compatibility with every laptop.
Check the laptop maker's recommended charging wattage and confirm that the intended laptop port and cable support the required charging and display connection.
If the connection cannot supply what the laptop needs, you may still need its original charger and the socket it occupies.
A monitor hub is useful only if its downstream connections match the devices used for track preparation. BenQ lists three downstream USB-A ports and one downstream USB-C port for the GW2790QT, but port count alone does not establish compatibility or adequate device power.
List each device, connector and power requirement, then compare them with the exact monitor's port specifications.
An unmatched device may still require an adapter, separate hub or powered dock.
Electrical Safety First warns that overloading an extension device can cause overheating and fire.
Do not daisy-chain extension leads. Check the device's marked current rating against everything connected to it; if extension leads are routinely needed, consider additional fixed sockets installed by a registered electrician.
Audio connections differ by model: BenQ lists speakers and a headphone jack for the GW2790QT, while Dell lists no audio for the P2425E. Those specifications do not establish how either monitor will serve a particular rehearsal setup.
Decide whether tracks need to reach headphones, an audio interface or a PA, then verify that connection path across the laptop and monitor.
A separate audio-routing device, headphones or powered speakers may still be needed.
The LG 27UP850K-W is a 27-inch 4K option for a desk where screen format and higher stated USB-C charging power both matter.
The BenQ GW2790QT is a QHD hub-monitor option when connecting USB peripherals is a priority alongside laptop charging.
The Dell P2425E offers a 24-inch, 16:10 WUXGA format with USB-C charging for consumers considering a smaller screen than a 27-inch model.
Yes, if it replaces the laptop charger at the desk: the laptop must support charging and video through the intended connection, and the monitor must supply enough power. LG specifies display, data and charging up to 90 W over USB-C for the 27UP850K-W; BenQ specifies 65 W Power Delivery, DisplayPort Alt Mode and data for the GW2790QT. The monitor itself still needs mains power.
Choose a rating that meets your laptop maker's recommended charging wattage, provided the laptop accepts USB Power Delivery through the intended port. Apple, for example, advises using a display or adapter that supplies at least the recommended minimum wattage for the Mac. A 90 W monitor is not automatically compatible, and a 65 W monitor is not automatically sufficient.
Do not rely on built-in speakers without checking your intended audio route. BenQ lists speakers and a headphone jack for the GW2790QT, whereas Dell lists no audio for the P2425E. Confirm how tracks will reach your headphones, audio interface or PA before buying.
Check the extension device's marked current rating against the equipment connected to it, and do not daisy-chain extension leads. Electrical Safety First warns that overloading an extension device can cause overheating and fire. If you regularly run short of sockets, consider additional fixed sockets installed by a registered electrician.
