Dell 24 240Hz Monitor SE2426HG: problems, parts and running costs

Checked: 2026-10-17

Summary

An entry-level 23.8-inch 1080p 240Hz Fast IPS gaming monitor with low input lag at any refresh rate and a consistently fast response time, held back by inverse ghosting at low refresh rates, low contrast, muted HDR and a tilt-only stand with no speakers. The only running cost is electricity, about 14 W in on mode. There is no US price to anchor value; the non-US anchors are about $106 at the China launch and CAD 139.99 in Canada.

Common problems and fixes

Inverse ghosting at low refresh rates — the only instrumented test located, RTINGS, lists it as a measured con. No fix is reported; it is a panel characteristic. [3]
Low contrast with no local dimming — RTINGS measured a low contrast ratio, so dark scenes look flat. No fix is reported. [3]
Muted HDR — a narrow HDR color gamut with muted highlights; HDR10 is listed on the product pages but the US datasheet’s HDMI line reads “HDR NA”, so HDR support over HDMI is ambiguous. No fix is reported. [3][1]
Tilt-only stand — no height, swivel or pivot adjustment; the fix is a third-party VESA arm on the 100 mm x 100 mm mount. RTINGS lists its tested unit, the SE2426HGS, with a height-adjustable stand; whether that is a different regional SKU is unresolved. [1][3]
No speakers, no USB hub, no USB-C — audio is a 3.5 mm headphone jack only. No fix is reported. [3][10]
HDMI 2.1 TMDS with an HDMI 2.0-bundled cable — the ports use the older TMDS signalling, which at 1080p240 still means 240Hz over HDMI, and the included 1.80 m cable is labeled HDMI 2.0. A newer cable is the workaround if a replacement is needed. [1][2]
Uncertain US warranty — a 3-year limited hardware warranty is reported for China and referenced for a UK listing, but US terms were not verified. Check the warranty sticker or Dell USA before buying. [4][5][6]

Parts and consumables

No replaceable parts or consumables reported. Routine ownership is electricity, a wipe of the screen and, if the tilt-only stand is not enough, an aftermarket VESA arm. Dell publishes a Simplified Service Manual with hardware replacement procedures for the SE2426HG on its US support site, but whether individual parts are actually sold was not verified. [13]

Yearly running cost

Electricity is the only recurring cost: the Dell datasheet lists 14.0 W in on mode, 0.3 W in standby, 0.3 W in off mode and 40.0 W max. No electricity price is reported in the research, so a yearly dollar figure cannot be computed.

When it is a good buy

No US price was captured for the SE2426HG; the anchors are the China launch price of 749 yuan, about $106 (Gizmochina, 2025-12-21), CAD 139.99 at Dell Canada (Reddit sales post, December 2025 era) and EUR 92.00 excluding VAT at Dell Ireland (October 2026 research check). RTINGS files it in its Under $200 bracket. At roughly $106–$140 it is a reasonable name-brand 1080p 240Hz IPS for competitive play; above about $150–$200 the documented weaknesses get harder to accept, and below about $100 it is attractive if entry-level picture quality is fine. For US context only, Dell USA listed the 144Hz SE2426H sibling at $99.99 as a bracket for this class.

Alternatives to check first:

ViewSonic XG2431 and LG 24GS65F-B — the direct competitors RTINGS names in this class; the better-equipped options if low contrast and muted HDR are dealbreakers. [3]
Dell SE2426H (144Hz, $99.99 at Dell USA) — the better choice if 144Hz is enough and you want to spend less. [12]
