Choose a monitor that gives you enough room to read your charts and, if you want to free a socket used by your laptop charger, can supply the power your laptop needs over a compatible USB-C or Thunderbolt connection. A 27-inch 4K screen offers more pixels for detailed charts than a 27-inch QHD screen, while a smaller 16:10 screen may suit a tighter desk; the monitor itself still needs a mains socket. Check your laptop’s video output, charging requirements and second-display support before deciding.
If sockets are scarce, you may want the monitor connection to carry video and charge your laptop instead of plugging in a separate laptop charger. LG UK and Dell UK list display connections and 90W charging on the cited models, but whether either works as intended depends on your laptop.
Small labels, table values and several open windows make resolution worth checking alongside screen size. The cited 27-inch monitors include 3840 × 2160 models from LG UK and Dell UK, as well as a 2560 × 1440 Dell UK model; your preferred text scaling will affect how you use that space.
If desk width is tight or you work with tall tables, a smaller 16:10 display may appeal. BenQ UK specifies a 24.1-inch, 2560 × 1600 panel and USB-C MST output for the RD240Q; adding another display still depends on compatible computer and monitor connections.
Start with the connection your laptop can use, then choose the screen format that fits your charts and desk. A USB-C socket on its own does not establish video, charging or second-display compatibility.
| Concern | What to check | Who this matters to |
|---|---|---|
| Fewer desk connections | Confirm USB-C or Thunderbolt video support on the laptop, then compare the monitor’s charging output with the laptop’s power requirements. | I want to connect my laptop for chart work without occupying another socket for its charger. Around 42% of consumers put fewer separate desk connections first. |
| Chart detail and window space | Compare native resolution and screen size together, and consider whether your preferred text scaling leaves labels comfortable to read. | When I inspect small chart labels alongside tables, keeping detail visible matters more than minimising the screen’s footprint. Chart-reading space is the primary need for around 33% of consumers. |
| Desk fit and vertical space | Measure the available desk space, including room for the stand; for a second display, check the computer’s supported connections and display count. | A narrower desk makes me favour a compact screen with room for tall tables, or a compatible way to add another display later. Around 25% of consumers prioritise that fit and flexibility. |
A USB-C connector alone does not tell you whether your laptop sends video through that port or can draw enough power from the monitor. You may still need the laptop’s separate charger.
Check your laptop’s video and charging specifications against the monitor’s stated USB-C functions and power output; confirm the cable supports the connection you intend to use.
A higher pixel count gives charts and windows more pixel space, but labels may need operating-system scaling to remain comfortable at your usual viewing distance.
Compare the physical screen size as well as resolution, and, if possible, view your usual charts at the scaling you would use.
A monitor output cannot add a second chart screen unless the computer, ports and displays support the required connection. BenQ UK states that daisy chaining is not available over HDMI or standard USB ports.
Check your computer’s supported external-display count, the monitor’s input and output ports, and the required cable before planning a daisy-chain setup.
Dell UK lists the U2724DE as a 27-inch QHD Thunderbolt hub monitor and the U2725QE as a 27-inch 4K hub monitor. Both cited models specify 90W Power Delivery.
LG UK specifies a 27-inch, 3840 × 2160 IPS panel for the 27U730A-B, with display, data and 90W charging over USB-C.
BenQ UK specifies the RD240Q as a 24.1-inch, 16:10, 2560 × 1600 monitor with 90W USB-C Power Delivery and USB-C MST output.
These monitors include wide-format, 4K, QHD, WUXGA and Full HD choices for chart work. If freeing a laptop-charger socket is central to your choice, check the exact model’s connection and charging functions against your laptop before relying on a single cable.

Consider this wide format if you want to arrange several charts side by side and have room for it on your desk.
The product name specifies a 49-inch, 32:9 QD-OLED screen with an 1800R curve and USB-C. Confirm the USB-C video and charging functions you need before planning to leave your laptop charger unplugged.
Image unavailable
Consider this screen if you want a large 4K area for charts and can accommodate its curved format.
The product name specifies 3840 × 2160 resolution, Type-C 65W and a USB hub. Check whether the Type-C connection provides the video and charging functions your laptop needs, and whether 65W is sufficient.

Consider QHD if you want chart-reading space without choosing one of the larger formats shown here.
The product name identifies an IPS QHD display. Check its exact connections and charging output against your laptop if reducing the number of plugged-in devices is important.
Image unavailable
Consider this format if your charts and tables benefit from vertical room and you do not need the pixel count of QHD or 4K.
The product name identifies an IPS WUXGA display. Confirm its dimensions, connection functions and laptop-charging output before choosing it for a limited-socket desk.
Image unavailable
Consider Full HD if your usual charts fit comfortably without the extra pixel space offered by the higher-resolution choices.
The product name identifies an IPS FHD display with a 75Hz refresh rate. Check its connections and charging output separately if you want the monitor to replace a laptop power connection.
Yes, if it can charge your laptop sufficiently while carrying its video connection, you may be able to unplug the separate laptop charger at the desk. The monitor still needs mains power, so check both devices’ connection and charging specifications before counting on that arrangement.
Choose an output that meets your laptop’s charging requirements, rather than judging by the USB-C connector alone. Compare the monitor’s stated output with your laptop manufacturer’s specifications and check that the laptop accepts charging through the port you plan to use.
You can only do so when your computer and monitors support the required connection and external-display arrangement. BenQ UK states that daisy chaining is not supported over HDMI or standard USB ports; check your computer’s display limits and both monitors’ ports before buying for this setup.
