For long sessions comparing tariff tables, start with a readable QHD screen and a stand that lets you position it comfortably; a 27-inch model is one option, not a requirement. Consider USB-C charging and a hub if you want a one-cable laptop desk, but check that your laptop supports video over USB-C and that the monitor’s rated power delivery meets its charging needs.
If you spend extended periods moving between supplier pages and notes, readable figures and a screen you can position at your desk matter more than entertainment features. Ofgem identifies unit rates and daily standing charges as figures to compare; the Health and Safety Executive also advises attention to workstation setup.
A USB-C connection could reduce cables if your laptop supports video through that port and the monitor supplies sufficient charging power. BenQ, AOC and LG list different power-delivery ratings on the models discussed below, so check the exact pairing.
If your main task is reading tariff pages and you already have a suitable laptop charger, assess the screen and stand before paying for docking or meeting features you may not use.
Decide whether your main difficulty is reading and comparing figures, positioning the screen for sustained use, or connecting a laptop with fewer cables. The checks differ even when one monitor offers several of these features.
| Concern | What to check | Who this matters to |
|---|---|---|
| Reading tariff figures | Check native resolution and screen size against your viewing distance; consider reading-oriented settings only on models that list them. | If I repeatedly compare unit rates, standing charges and tariff terms, I want text I can read without struggling to follow the figures. Roughly 42% of consumers put reading clarity first. |
| Screen position | Check the stand’s adjustment range and desk depth; if you plan to use an arm, confirm the monitor’s mounting option. | A screen that sits awkwardly at my desk would make a long comparison session harder to manage. For around 33% of consumers, workstation fit is the primary concern. |
| Laptop connection | Confirm USB-C video support, the monitor’s power-delivery rating and the cable and ports needed for your setup. | When my laptop is the main computer, I would rather connect the display and charge through one cable if both devices allow it. About 25% of consumers prioritise that connection. |
Ofgem explains that the cap concerns unit rates and standing charges, not a maximum total bill. A clearer monitor cannot make one annual headline figure a sufficient tariff comparison.
Compare the applicable unit rates, standing charges and tariff terms using your own expected consumption.
BenQ lists 65W power delivery for the GW2790QT, AOC lists 90W for the Q27E4CV, and LG lists up to 15W for the 27U631A-B. The presence of a USB-C port alone does not settle whether your laptop can display video and charge as intended.
Check the laptop’s video-output support and charging requirement against the exact monitor, port and cable.
You may still need to use a separate laptop charger if the monitor cannot supply the power your laptop requires.
The Health and Safety Executive identifies poorly designed workstations and incorrect display-screen use as potential contributors to discomfort, fatigue and eye strain. Resolution does not determine where the screen sits.
Check desk depth and your seated screen position, then look for the adjustment you need or a suitable mounting option.
If the supplied stand cannot position the screen appropriately, a separate arm or stand may be needed.
The GW2790QT is a model to examine if QHD resolution, stand adjustment and a USB-C laptop connection are priorities.
The Q27E4CV is a model to examine for a QHD laptop desk where height adjustment and USB-C docking matter.
The 27U631A-B is a model to examine if a QHD screen and document-oriented display settings matter more than higher-power laptop docking.
These QHD and 4K monitors offer different screen formats for comparing tariff pages. Use the listed variant as a starting point, then check the stand, desk fit and laptop connection you need.

Consider this larger-screen option if you have room for tariff pages and other documents; check its physical dimensions against your desk.
The product name specifies 3840 × 2160 resolution, 165Hz and Type-C 65W. Confirm the exact screen diagonal before buying, and check USB-C video support and charging compatibility with your laptop.

Consider this WQHD option if reading tariff tables and positioning the screen at your study desk are priorities.
Check the stand adjustment you need. If you also intend to charge a laptop through the monitor, confirm its power-delivery rating and your laptop’s requirements.
No image available
Consider this WQHD option for tariff pages and notes if its screen dimensions suit your desk and viewing distance.
Check the stand arrangement before choosing it. If laptop charging through the monitor is essential, confirm the required USB-C connectivity for this model.

The 27-inch QHD format is an option for viewing tariff pages; decide separately whether you would use this gaming variant’s features.
Its product name specifies an OLED screen and 240Hz refresh rate. Check stand adjustment and USB-C laptop connectivity against your own setup before choosing it for study use.

Consider this QHD option if you want to assess a more compact screen for reading tariffs at your desk.
Check whether its screen area suits your viewing distance. If you want the monitor to charge your laptop, compare its stated USB-C power delivery with the laptop’s charging requirement.
No special monitor is required to compare tariffs. Choose a screen you can read and position comfortably, then compare the applicable figures: Ofgem distinguishes unit rates and daily standing charges and explains that the price cap does not fix your total bill.
Only if the monitor’s power delivery meets your laptop’s needs and the connection supports your intended setup. BenQ lists 65W for the GW2790QT, AOC lists 90W for the Q27E4CV, and LG lists up to 15W for the 27U631A-B; also check that your laptop supports video through its USB-C port.
No. QHD describes screen resolution, while the stand determines how you can position the display. For a study desk used over long periods, check screen height and desk depth as well as resolution; the Health and Safety Executive advises attention to workstation setup when using display-screen equipment.
Look for an appropriate electrical-equipment reuse or recycling route available where you live. GOV.UK describes the UK waste electrical and electronic equipment framework as encouraging recovery, reuse and recycling; check local arrangements before disposing of the monitor.
