HDR & Brightness Reality
No HDR tier is listed for the P2423DE. With 300 cd/m² typical brightness, 1000 : 1 native contrast and no peak-brightness figure, bright highlights cannot be separated from the rest of the image like they are on real HDR hardware. This model concentrates on USB-C docking and QHD workspace. That is a reasonable trade for its intended use, but an HDR label from software would not change the panel limits.

Frequently Asked Questions
01 Will text look clean on the P2423DE at 123 PPI? +
At 23.8-inch and 2560 x 1440, 123 PPI is sharper than ordinary office screens, so small text and dense spreadsheets remain clean. It should be judged at normal desk distance rather than from the resolution label alone.
02 How does the P2423DE's published refresh range affect motion? +
The published ceiling is 75 Hz, so motion can use the full 49 Hz - 75 Hz range where the source supports it. Mid-range graphics are sensible for QHD near 75 Hz; office workloads are undemanding.
03 What is the simplest way to connect a laptop to the P2423DE? +
The published USB-C input supports DP Alt Mode and carries power as listed: 1 x USB 3.2 (Type-C; upstream; 90W; DP Alt Mode). The remaining hub connections can then serve peripherals.
04 What should not be overlooked before buying the P2423DE? +
The main compromise is no built-in speakers. The specification also lists no meaningful HDR tier, so the monitor should be bought for SDR use.
05 Which hardware difference matters between the P2423DE and Dell P2423D? +
It uses the same compact 23.8-inch QHD panel, then adds 90 W USB-C, Ethernet and DisplayPort MST. The decision should follow that practical difference rather than the shared family styling.
