Dell S3225QC 32" Plus 4K QD-OLED Monitor - 120Hz, HDR
The Dell S3225QC 32" Plus 4K QD-OLED Monitor is built for creative professionals and immersive computing who need accurate colour and deep contrast from a single-cable desk setup. Its Quantum Dot-OLED panel with Oxide TFT delivers a 1,500,000:1 contrast ratio and 99% DCI-P3 colour coverage, while five built-in speakers with AI-driven head-tracking spatial audio remove the need for a separate sound system.
Why this product
QD-OLED panel with extreme contrast
The Quantum Dot-OLED panel achieves a 1,500,000:1 contrast ratio and true per-pixel black levels, certified to VESA DisplayHDR True Black 400.
99% DCI-P3 colour gamut
With a typical DCI-P3 coverage of 99% (CIE 1976), this display suits colour-critical workflows in photography, video editing and design.
120 Hz refresh with 0.03 ms response
A native 120 Hz refresh rate and 0.03 ms gray-to-gray response keep motion sharp, whether in fast-paced content or competitive play.
AMD FreeSync Premium Pro adaptive sync
FreeSync Premium Pro eliminates screen tearing across the 48–120 Hz range via HDMI or USB-C, with low-framerate compensation included.
Single-cable USB-C setup up to 90 W
The upstream USB-C port supports DisplayPort 1.4 Alt Mode and delivers up to 90 W of Power Delivery, connecting a compatible laptop with one cable.
AI-enhanced 3D Spatial Audio built in
Five 5W speakers with AI-driven head-tracking and beamforming technology produce directional audio without an external sound bar.

- Works with any PC or laptop that outputs video over HDMI 2.1 (supports up to 3840×2160 at 120 Hz with VRR and HDR).
- Works with laptops and workstations that support USB-C DisplayPort 1.4 Alternate Mode — carries video, data and up to 90 W charging over a single cable.
- Compatible with AMD FreeSync Premium Pro on supported AMD GPUs via both HDMI and USB-C.
- Dolby Vision HDR playback requires a source device and application that also support Dolby Vision output.
- The two downstream USB-C ports (5 Gbps) provide data transfer and up to 15 W charging only — they do not carry a video signal.
- No DisplayPort (DP) input is provided; sources that output only over DisplayPort require an active adapter.
Best for
- Colour-critical creative work — 99% DCI-P3 coverage and a QD-OLED panel make it well-suited for photo editing, video colour grading and graphic design.
- Single-cable laptop users — the 90 W USB-C Power Delivery upstream port lets a compatible laptop run display, data and charging through one connection.
- HDR movie and gaming enthusiasts — VESA DisplayHDR True Black 400 and Dolby Vision HDR certification, combined with a 1,500,000:1 contrast ratio, produce deep blacks suited to HDR content.
- Gamers who value smooth motion — 120 Hz native refresh, 0.03 ms gray-to-gray response and AMD FreeSync Premium Pro reduce tearing and motion blur.
- Users who prefer built-in audio — five 5W speakers with AI spatial audio and beamforming reduce desk clutter without sacrificing directional sound.
Trade-offs
- DisplayPort-only setups — there is no native DP input; users whose GPU provides only DisplayPort will need an active adapter.
- Buyers needing more than one video input — the monitor provides just one HDMI port alongside the USB-C video inputs, limiting multi-source switching.
- Laptops with USB-C data only — the 90 W single-cable benefit applies only when the laptop's USB-C port supports DisplayPort Alt Mode; data-only USB-C ports will not carry video.
- Space-constrained desks — at 10 kg with stand and a stand depth of 223.70 mm, this is a substantial panel that requires adequate desk depth and surface strength.
Feel captivated by sound and visuals like never before on the world's first QD-OLED monitor built with AI-enhanced 3D Spatial Audio.
