HDR & Brightness Reality
Dell lists no HDR tier here, which at 400 cd/m2 is defensible even though the panel would likely clear a DisplayHDR 400 bar. The more interesting number is 2000:1 - IPS Black doubles the contrast of a normal IPS, and on a text panel that shows up every day in dark-mode editors and photo shadows. It is a far more useful upgrade than an entry HDR badge would have been.

Frequently Asked Questions
01 Why does it say 23-87 Hz? +
The low floor is for power saving and video playback cadence; the 87 Hz ceiling is a small overclock above 60. It is not a gaming feature - it just makes scrolling marginally smoother than a fixed-60 panel.
02 Is this better than the newer U2725QE? +
Close. The U2725QE adds 120 Hz, DisplayHDR 600 and 3000:1 IPS Black contrast, but its USB-C is data only. This older model has a full 90 W USB-C dock. If charging over one cable matters, this one wins.
03 Is 163 PPI usable without scaling? +
Everything is razor sharp but very small at 100%. Most people run 150% scaling, which gives 1440p-sized interface elements with 4K crispness. That is the point of a 27-inch 4K.
04 Is there any audio for meetings? +
No. There is a 3.5 mm output only, so plan on a headset or desk speakers for calls.
05 What does the Power Button Sync feature do here? +
It links the monitor's power button to a connected Dell machine, so one press turns both on or off. A small convenience that adds up on a docked desk.
