Dell P2423D: Specs, Features, Pros & Cons
This review measures the Dell P2423D against the full 41-spec sheet we track for monitors, comparing it like for like with the 69 other models in our database. It earns a VS Score of 28 out of 100 — the weighted result of every verified specification measured against the class average.
On the spec sheet it is strongest in ergonomics & design and weakest in picture. None of our retail partners currently lists the Dell P2423D, so availability may be limited; a missing price never affects the VS Score. A transparency note: this spec sheet is 51% complete. Anything unverified shows as Unknown and is left out of the score — we never estimate a missing value.

Editor’s note
The P2423D is an office monitor and makes no pretence otherwise. It is 23.8 inches — Dell markets it as 24 — running 2560×1440 at 60Hz, and the reason to choose it over a cheaper 1080p screen is pixel density: at this size QHD makes text noticeably crisper, which is what you notice across a working day of documents and spreadsheets.
Everything about it is aimed at that use. 99% sRGB coverage and 300 nits are right for an indoor desk. The anti-glare coating handles overhead lighting. The stand does everything — height, tilt, swivel and pivot into portrait, which is genuinely useful for reading long documents or code. There is a four-port USB 3.2 hub built in.
Two things to be clear about before ordering. This is the P2423D, not the P2423DE: the E model is the USB-C hub version that charges a laptop over a single cable, and this one has no USB-C at all — you connect over DisplayPort 1.2 or HDMI. People buy the wrong one regularly. And there are no speakers.
For gaming it is the wrong monitor. 60Hz with a 5ms response and no adaptive sync means motion is exactly as smooth as an office monitor from a decade ago.
Buy it if you work at a desk all day and want sharp text, a stand that adjusts properly and a built-in USB hub. Skip it if you want single-cable laptop docking, or play anything more demanding than solitaire.

How the VS Score works — and what it can’t tell you
Every measurable spec is scored against the average of all the monitors we track: matching the class average scores 50, clearly beating it climbs towards 100, and each spec counts according to an editorial weight that reflects real-world impact — a battery-capacity gap moves the score far more than a colour-options list. The quality bars on the spec cards above show where this model sits inside the full range for its class, and the overall VS Score rolls every weighted result into one number.
Unknown values are never estimated. A spec this product doesn’t report simply drops out of its scoring — it isn’t penalised with a guess — but a thinner spec sheet does mean a score built on fewer data points, which is why completeness is disclosed under About this data.
Most importantly: a spec-sheet lead is not the same as a better product. Megapixels, gigahertz and benchmark points describe capacity, not experience — image processing, software optimisation, thermals, haptics and ergonomics decide how a device actually feels, and no table captures reliability or long-term support quality. Treat the VS Score as a structured summary of what can be measured, not a substitute for your own priorities.
About this data
- Specifications are compiled from each manufacturer’s official spec sheet, cross-checked against trusted specification databases, and normalised into one schema so identical things are compared identically.
- Specifications last verified August 1, 2026.
- Data completeness: 21 of the 41 specs in this category are verified (51%). Anything we could not verify is shown as Unknown — never estimated — and is excluded from the score.
- Prices and availability come from live retailer feeds via our shopping partners and refresh throughout the day; a missing price means no partner currently lists the product, not that it is discontinued.
- Want the full picture? Our editorial guidelines explain how we research products, weight the scores and stay independent.

The bottom line
The Dell P2423D earns a VS Score of 28, trailing most of the 70 monitors we compare here, at least on the spec sheet. It stands out for has USB hub, has pivot and has swivel. Just be aware of 3.98 ms more response time and 156.37 Hz less refresh rate before you buy. Weigh those trade-offs against what matters most to you.
The VS Score is generated automatically from the weighted specifications above, measured against all other monitors in our database. Treat it as a shortlisting guide — not a substitute for your own priorities.
