Dell S2725QC
No budget ceiling
Still the cheapest true single-cable 4K here — 27-inch 4K at 120Hz with 65W USB-C charging and a height stand, on a card built from 11 sources.
Fit ledger — need → measured evidence
■ The catch — co-equal billing, always
65W won't charge a big laptop. It covers ultrabooks and 13-14 inch machines, but a 16-inch MacBook Pro or a high-performance Windows laptop needs 90W+ — plugged in here it runs at a net battery drain under load. Check what your laptop's own charger delivers before you buy the single-cable story.
Dealbreaker? Runner-up №1 — the ASUS ProArt PA279CRV pushes 96W ↓

Traps — this verdict avoids
Why the Dell S2725QC is right for you
It avoids every trap below — and for just me, no cap, it is the pick because it delivers:
Watt-starved USB-C
Power Delivery is the one number that decides whether the monitor charges the laptop plugged into it. 65W covers most ultrabooks, a 14-inch MacBook Pro needs 70W+, and a 16-inch or a performance Windows laptop needs 90W+. Under-spec it and the machine drains while it is plugged in.
The 150% scaling tax
4K at 27 inches needs Windows scaling at 150% for comfortable text size, and some legacy applications handle DPI scaling poorly. Test the software you actually live in before committing to 4K.
June's prices are gone
Every 4K pick in this category is 15-30% more expensive than it was a month ago: the Dell S2725QC went ~$252 to ~$313 and the ASUS ProArt PA279CRV ~$334 to ~$399. A price quoted in a June review is not what you pay today.
