Dell UltraSharp U2725QE
No budget ceiling
The one monitor here that genuinely replaces a docking station — 140W Thunderbolt 4, 2.5GbE Ethernet, a KVM and seven downstream ports, on the sharpest panel in the comparison.
Fit ledger — need → measured evidence
■ The catch — co-equal billing, always
$639 buys the dock, not just the panel — and it is around 8ms. The LG 27UP850K-W gives you the same 27-inch 4K and single-cable charging for $350; the extra $289 is 120Hz, IPS Black contrast, 2.5GbE, the KVM and 50 more watts. Measured response time is roughly 8ms, so 120Hz here buys a fluid desktop, not competitive frame timing.
Dealbreaker? Runner-up №1 is the same 27" 4K single-cable for $289 less ↓

Traps — this verdict avoids
Why the Dell UltraSharp U2725QE is right for you
It avoids every trap below — and for just me, no cap, it is the pick because it delivers:
The hub quietly drops to USB 2.0
Over plain USB-C DisplayPort Alt Mode, driving 4K at 120Hz eats the lanes the hub needs for data — your downstream USB ports fall back to USB 2.0 speeds and an external SSD crawls. Keeping both 4K120 *and* 10Gbps hub throughput needs a Thunderbolt 4 host, not just a Thunderbolt 4 monitor.
Same name, different panel
The Samsung ViewFinity S80UD ships as a 27-inch IPS, a 32-inch IPS and a 37-inch VA under one model name at very different prices; the BenQ GW2786TC is a different price in black and in white. Panel size, panel technology and colourway are part of the SKU — check the full model number (LS37D800UANXZA, not LS27D802UANXGO) before you click buy.
Watts are negotiated, not promised
USB-C PD on these monitors runs 65W to 140W, and the number is a ceiling — the laptop and monitor negotiate down. A 65W monitor will charge a 16-inch MacBook Pro, just slower than it drains under load. Only 140W Extended Power Range over Thunderbolt 4 (the Dell U2725QE and U3225QE) keeps a high-wattage laptop at full charge while you work.
