Dell S2725DSM vs Dell P2426H
The clearest split between the Dell S2725DSM and the Dell P2426H is refresh rate. Dell S2725DSM runs at 144Hz versus 120Hz on the Dell P2426H. That gap is meaningful in fast-paced games — enemies move more smoothly, tracking feels more responsive, and the transition from 60fps to higher frame rates is clearly visible. For everyday desktop use and productivity, both feel identically fluid.

Both displays use IPS panel technology, so panel-level contrast and viewing angles are comparable. The differences come down to calibration, brightness, and HDR tier.
Refresh rate is the headline gaming spec. Dell S2725DSM runs at 144Hz versus 120Hz on Dell P2426H -- a 24Hz gap. 144Hz is the entry point for serious gaming. The Dell S2725DSM reaches this threshold; the Dell P2426H at 120Hz is adequate for casual gaming but not competitive play.On response time: Dell S2725DSM (4 ms (GtG)1 ms (MPRT)) versus Dell P2426H (5 ms (GtG)). VRR (Variable Refresh Rate) eliminates screen tearing by syncing the monitor to your GPU's frame output. Both monitors support adaptive sync: Dell S2725DSM with AMD FreeSync, and Dell P2426H with -.
HDR certification not disclosed for either display. Assume SDR-only output unless confirmed by the manufacturer.
Dell S2725DSM at QHD gives noticeably sharper text than FHD -- more pixels per inch means finer fonts and crisper UI at close desk distances. Neither monitor offers full ergonomic adjustment. A VESA monitor arm is recommended for proper positioning if you spend long hours at your desk.
These two monitors have different resolution targets, so GPU requirements differ. Dell S2725DSM at QHD (1440p) and 144Hz demands more GPU headroom than Dell P2426H at FHD (1080p) and 120Hz. GPU tiers below cover both monitors.
Both monitors offer comparable connectivity. HDMI 2.1 on both supports console gaming at high frame rates.
Connectivity score methodology: USB-C Power Delivery (2 pts) · USB hub ports (2 pts) · Ethernet (1 pt) · HDMI 2.1 (1 pt) · KVM switch (2 pts) · Thunderbolt (2 pts). Higher score = more complete connectivity package. Ties broken in favour of USB-C power delivery.
Both monitors have basic stand adjustment. If you need precise positioning, a VESA-compatible monitor arm is recommended -- check the spec table for VESA mount support (typically 75×75mm or 100×100mm).
Use our free screen size comparison tool, PPI calculator, and power consumption calculator to go deeper than spec numbers alone. These display comparison tools help you accurately compare monitors and TVs beyond what a spec table shows -- from physical dimensions to real-world electricity costs.
Bottom line: For most buyers, the Dell S2725DSM is the stronger choice, leading on full height and tilt adjustment, QHD resolution, 99% sRGB colour accuracy. The Dell P2426H is worth considering if cost is the deciding factor or if its specific connectivity or form factor better matches your desk setup.

Dell S2725DSM vs Dell P2426H: What Actually Matters
On paper, Dell S2725DSM and Dell P2426H share several headline specs -- but the differences that matter emerge when you look at panel characteristics, factory calibration, and ergonomic flexibility rather than just the spec sheet totals.
On the sharpness question: QHD resolution on the Dell S2725DSM renders noticeably crisper text and finer detail than Full HD -- particularly visible on a 27-inch panel where pixel density directly affects how clean fonts and fine UI elements look at normal viewing distances. The trade-off is GPU demand; pushing QHD at high refresh rates requires meaningfully more graphics horsepower.
Strengths Worth Knowing
The Dell S2725DSM stands out for ips panel — wide 178°/178° viewing angles with accurate, consistent color reproduction and anti-glare matte coating — effective reflections control for comfortable all-day use. The main compromise: ips contrast ratio (1500 : 1) — blacks look grey in dark viewing environments vs va/oled.
The Dell P2426H stands out for very lightweight at 2.96 kg (without stand) and low power consumption (11.7w avg, 74w max). The main compromise: no usb-c with power delivery or ethernet.
❓ Frequently Asked Questions
For gaming, the Dell S2725DSM has the edge thanks to its 144Hz maximum refresh rate. Higher refresh rates produce smoother motion and reduce perceived input lag -- critical advantages in competitive shooters and action titles. If both share the same Hz, compare response time in the spec table above.
Both the Dell S2725DSM and Dell P2426H use IPS -- the differences lie in resolution: QHD versus 1080p. Resolution affects pixel sharpness, screen real estate, and the GPU horsepower needed to run games at full Hz.
The Dell S2725DSM runs at QHD versus 1080p on the other. QHD resolution means more pixels per inch -- sharper detail in games and more screen real estate for multitasking. The trade-off is that QHD gaming requires more GPU or console horsepower to maintain high frame rates. If you are on a mid-range setup, 1080p will achieve higher, smoother frame rates more easily.
For all-day productivity work -- documents, spreadsheets, coding, and content creation -- resolution and panel colour accuracy matter most. The Dell S2725DSM is the stronger daily driver based on overall specification score. For long hours, also look for a model with flicker-free backlight and low blue-light mode -- check the spec table above for those details.
The Dell S2725DSM is the stronger all-round choice based on its overall score of 3.7/5. That said, if your priority is specifically competitive gaming at the highest possible refresh rate, see the Quick Answer section at the top of this page for use-case-specific recommendations. The Dell P2426H is not a bad choice -- it simply trails on overall specification weight, which may not reflect the single spec most important to your setup.
IPS (In-Plane Switching) panels are the most common in quality monitors -- they offer wide viewing angles and accurate colour reproduction, making them ideal for design work, general use, and brightly lit rooms. VA (Vertical Alignment) panels have a higher native contrast ratio, producing deeper blacks, which benefits dark-room gaming and movie watching. OLED panels work differently: each pixel emits its own light, enabling true blacks, near-infinite contrast, and perfect viewing angles -- at the cost of higher price and some burn-in risk with static content.
For non-gaming use -- web browsing, documents, video calls -- 60Hz to 75Hz is completely adequate and you will not feel the difference from a 144Hz or 240Hz panel. Where higher refresh rates genuinely improve the experience beyond gaming is in cursor smoothness during scrolling and desktop navigation, which some users appreciate. In short: the step from 60Hz to 75Hz has minimal benefit; the step from 60Hz to 144Hz is noticeable but not essential for productivity.
