Dell 27 Plus QHD S2725DSM: problems, parts and running costs

Checked: 2026-10-17

Summary

The S2725DSM is a 27-inch QHD 144 Hz IPS monitor whose real limits are the input set (one HDMI, one DisplayPort, no USB-C) and, for some owners, IPS glow and eye discomfort in dark rooms. [1][6][7] There are no consumables; electricity is the only continuing cost, roughly $13.37 a year at 8 hours of daily use, and an out-of-warranty repair quote can exceed the $169.99 October 2026 sale price. [3][4] It is a good buy at $169.99, acceptable up to $195, and weak above $200, where the USB-C S2725DC and 4K S2725QS become the comparison. [3][8][12]

Common problems and fixes

No USB-C, no USB hub — the monitor has one HDMI and one DisplayPort 1.4 only; a USB-C laptop needs an adapter or dock, and a two-PC desk needs a separate switch. Not a defect, a design limit; nothing to fix. [1][3]
IPS glow in dark scenes — an owner reported IPS glow in darker scenes; it is a familiar LCD viewing-angle/backlight effect, not a damaged panel, and no S2725DSM-specific defect rate exists in the sources. Inspect a new unit at normal brightness and reasonable distance, then use the seller’s return window if uniformity is unacceptable. [6]
Eye discomfort despite eye-comfort branding — one owner reported eye pain after a single day despite changing display settings, while another found this model unusually comfortable; advertised flicker reduction cannot guarantee personal comfort. [7][6]
Overdrive artifacts in the Extreme preset — Dell’s own guide warns the 4 ms Extreme setting can add artifacts and recommends Normal or Fast; the 1 ms figure is an MPRT mode, not an ordinary gray-to-gray response. Switch the Response Time OSD to Normal. [2]
DisplayPort cable not bundled — the box includes an AC power cable and a 1.8 m HDMI cable, so DisplayPort setups start with a separate purchase. [1][2]
Panel damage from improper cleaning — use a slightly water-dampened soft cloth; alcohol, ammonia, detergent and spraying water directly onto the panel can cause non-warranty damage. [2]

Parts and consumables

DisplayPort 1.4 cable (not bundled) — Monoprice Select Series, 6 ft, item #31181, was $8.29 at Monoprice US when checked (October 2026); a nonproprietary compatible accessory, not a Dell original; buy once to use the DisplayPort input, replace only if damaged. [11]

No filters, ink or scheduled parts exist. Internal panel, power-board and speaker parts have no documented US retail prices and no replacement schedule, so a repair reserve is a guess; contact Dell with the Service Tag before shipping. [4]

Yearly running cost

Required annual consumables: $0. Electricity is the only continuing expense. CHIP measured 22.3 W operating and 0.3 W standby on this exact model; at 8 hours on and 16 hours standby a day with power at $0.20/kWh, that works out to 66.87 kWh/year, roughly $13.37 a year before tax. [3] Dell rates the panel at 21.4 W typical and 65 W maximum; the maximum is a ceiling, not a normal draw. An out-of-warranty repair quote can exceed the $169.99 October 2026 sale price, so a repair reserve is not honestly calculable. [4]

When it is a good buy

Observed US offers in October 2026: $169.99 promotional on Dell’s US site, matched by Micro Center at $169.99 (SKU 965376, down from $229.99); Newegg listed $219.99 sold by Dell Technologies; a Walmart third-party listing showed $230.99. [3][8][9][10] The observed asking range across sampled offers was $169.99–$230.99, not an audited median. [3][8][9][10] $150 or less new is excellent; $150–$175 is a good buy for QHD 144 Hz with a full stand; $175–$195 is acceptable if authorized service and easy returns matter. [3][8] Above $200, first compare the USB-C-equipped S2725DC at $199.99 Dell direct for one-cable laptop docking, or the 4K S2725QS at $229.99 from Micro Center for sharper fonts and photo work. [12][8] A competitive gamer can also look at the 180 Hz G2725D, though some Dell listings show it unavailable. [13]
