Rank #1 in Best 24 Inch Monitor 2026: 10 Ranked, and Three Numbers That Don't Add Up
Dell 24 Plus S2425HSM 24-Inch 144Hz IPS Monitor
Price and rating as shown on Amazon when we collected them. Both change.
The Dell 24 Plus S2425HSM takes first place in this guide at £89.26, and it is the entry where the headline refresh rate survives every part of the listing it appears in. The name says 144Hz, the first bullet says 144Hz, the spec table says 144 Hz, and the bullet about connections says both HDMI ports run Full HD at 144Hz with AMD FreeSync. Nothing in the listing asks you to follow an overclocking procedure to reach that figure, and nothing in it calls the panel anything other than the 1920x1080 IPS screen the bullets name.
The smaller numbers hold together as well. The 1500:1 contrast ratio sits at the top of the range the other IPS screens in this guide quote, 99% sRGB and 300 cd/m2 come from the same bullet, and the 1ms MPRT response time matches the title. Two spec fields do disagree with the bullets: the table gives a Screen Size of 24 Inches against a bullet of 23.8", and a Pixel Pitch of 93.0, a figure that does not fit a 23.8-inch 1080p panel. Both are flagged as listed below. Everything on this page comes from the Amazon listing for this monitor, not from any test of our own.

Questions people ask
Is the 144Hz on this Dell monitor overclocked?
According to the listing, no. The model name, the first bullet and the spec table all state 144Hz, and the bullet on connections says dual HDMI ports support FHD at 144Hz with AMD FreeSync. The listing does not describe any overclocking procedure for the S2425HSM.
How big is the screen?
The listing gives two figures. The bullet says 23.8" FHD (1920x1080), while the spec table's Screen Size field says 24 Inches. We have quoted both rather than picking one.
Does the Dell 24 Plus S2425HSM have built-in speakers?
Yes, the listing states dual 3W speakers with preset audio profiles, so no external speakers are needed for entertainment or work.
What does the 4.6 rating actually cover?
The listing reports 4.6 out of 5 from 316 ratings. The star breakdown shown alongside it adds up to 100 ratings - 75 five-star, 16 four-star, 5 three-star, 1 two-star and 3 one-star - so the two figures do not cover the same number of ratings.
What can I connect to it?
The listing mentions HDMI only. It states dual HDMI ports supporting FHD at 144Hz with AMD FreeSync, and lists HDMI under both network and hardware connectivity. No DisplayPort or USB-C is mentioned.
Is the contrast ratio unusual?
The Dell quotes 1500:1, which is at the top of the 1000:1 to 1500:1 range the other IPS screens in this guide quote, so it is not the outlier that the 4000:1 claim elsewhere in the batch is. The listing also labels the display 'LED' under Display Type and 'LCD' under Display Technology, while the bullets call the panel IPS.
