Monitor deals: compare resolution, refresh rate and USB-C power

A 27-inch monitor at a lower price may have a different resolution, stand or connection from the one you want. Build a shortlist around your computer and desk. Then compare the exact monitor code, with the cost of any cable, mount or adapter you will need.

Desk research from the sources linked below. Price examples are illustrative, not live offers. We have not hands-on tested the products.

Size is only one part of the picture

Record diagonal size, resolution and maximum supported refresh rate together. Dell's UK S2725QC page, for example, specifies a 27-inch 3840-by-2160 display at up to 120Hz. Another 27-inch Dell model is not automatically the same offer. Keep the complete model code in price alerts and retailer comparisons.

Choose the job before chasing the largest specification. For office work, think about text size, workspace and your application's scaling. For gaming, check the resolution and frame rate your system can produce, then read the monitor's supported connection modes. Tillio has not tested motion quality, colour accuracy or text rendering on these screens. Those judgments need more than a sale card and a headline number.

Read upstream and downstream USB-C separately

The S2725QC specification distinguishes its USB-C upstream connection, with DisplayPort Alt Mode and up to 65W power delivery, from a downstream USB-C port providing up to 15W. Both use USB-C, but they have different jobs. Do not choose the downstream socket expecting it to run and power your laptop.

For a one-cable desk, check that the laptop supports display output over the intended connection and compare its charging requirement with the monitor's supply. Consult both manuals about supported resolution and refresh rate. If the laptop needs a separate charger for your use, keep that in the plan instead of treating a 'USB-C monitor' label as a promise of a complete docking solution.

Add the desk parts that the cheaper offer lacks

Check stand adjustment, mounting compatibility, included cables and the footprint on your desk. A fixed stand may be acceptable at your eye level; it may also make a cheaper screen need a separate mounting solution. Check the screen and mount's published fit and weight requirements before including a mount price.

Illustrative example, not live offers: Monitor A is £150 delivered but your planned setup needs a £25 compatible mount and £10 cable, totalling £185. Monitor B is £175 delivered with the adjustment and cable you need. B saves £10 for that desk. If you already own compatible parts, recalculate using only what you actually need to buy.

Finish with the selected seller and condition

New, open-box and refurbished monitor offers need separate condition checks. Ask about marks, screen defects, included stand and accessories, then read the seller's return arrangements and defect policy. A manufacturer warranty statement for a new direct purchase should not be pasted onto another seller's used offer.

Use VAT-inclusive delivered totals for a personal purchase, and confirm the selected option before payment. Where delivery depends on postcode, resolve it before calling an offer cheapest delivered. Set a price target for the exact suitable screen once those details are clear; a different resolution or charging output is a separate buying choice.
