Dell S3225QC 32" 4K QD-OLED review
A 32" 4K QD-OLED with 120Hz and one-cable USB-C
Dell's 31.5" QD-OLED puts perfect blacks, 120Hz and 0.03ms response on a desk monitor with USB-C and 3D spatial audio built in.
What we liked
- True blacks and huge colour volume
- 120Hz for work and play on one screen
- Full height/tilt/swivel/pivot stand
- One-cable USB-C setup
What we didn't
- OLED burn-in needs care with static UI
- Text fringing up close
- Costs more than an IPS 4K
Specifications
| Panel | 31.5" QD-OLED, 3840×2160 |
|---|---|
| Refresh | 120Hz |
| Response | 0.03ms GtG |
| Pivot | Yes, to portrait |
QD-OLED is the reason to buy this panel. Blacks are genuinely black, colour volume is far ahead of any IPS in the price range, and 120Hz with 0.03ms response makes scrolling and gaming feel immediate on the same screen you work on.
At 31.5" and 4K you get 140 PPI, so macOS runs a scaled resolution and Windows is clean at 150%. QD-OLED subpixel layout means text fringing is visible if you sit very close — at normal arm's length it disappears.
The built-in AI-enhanced 3D spatial audio is better than typical monitor speakers, and the stand adjusts for height, tilt, swivel and pivot. Burn-in risk is the usual OLED caveat: hide the taskbar and let the panel run its pixel refresh.
