Dell UltraSharp U3225QE 32" 4K 120Hz Thunderbolt Hub Monitor
The Dell UltraSharp U3225QE 32" 4K 120Hz Thunderbolt Hub Monitor is built for professionals who demand accurate colour and deep contrast in a single-cable desktop setup. It is the world's first IPS monitor with a 3000:1 contrast ratio, delivering 47% deeper blacks than conventional IPS panels alongside 99% DCI-P3 colour accuracy. The integrated Thunderbolt 4 hub with up to 140W power delivery lets creatives and knowledge workers drive a full workstation from one connection.
Why this product
World's first IPS with 3000:1 contrast ratio
IPS Black Technology achieves 47% deeper blacks than conventional IPS, bringing shadow detail and on-screen contrast closer to what you'd expect from VA panels without sacrificing IPS viewing angles.
99% DCI-P3 colour with Delta E <1.5
Factory-calibrated colour accuracy covers DCI-P3, Display P3, sRGB and BT.709 colour spaces, making it suitable for photo editing, video grading and design work straight out of the box.
Up to 140W Thunderbolt 4 power delivery
The Thunderbolt 4 upstream port supplies up to 140W EPR, enough to charge a high-performance laptop while running the display and all connected peripherals through a single cable.
120Hz refresh rate for smooth visuals
A variable refresh rate range of 48–120Hz reduces motion blur during scrolling and light creative work, with HDMI 2.1 additionally supporting VRR for compatible sources.
Built-in Thunderbolt hub with 2.5GbE
Onboard ports include four USB-A, two USB-C 3.2 Gen 2, a front pop-out hub and a 2.5GbE RJ-45 port, turning the monitor into a full docking station.
TÜV 5-star eye comfort certification
ComfortView Plus, flicker-free backlighting, an ambient light sensor and an anti-glare low-reflectance panel combine to reduce eye strain during long working sessions.

- Works with any Thunderbolt 4 or USB4 laptop as a single-cable docking monitor with up to 140W charging.
- Compatible with standard DisplayPort 1.4 and HDMI 2.1 sources, including desktop PCs and gaming consoles that output 4K.
- Supports daisy-chaining a second Thunderbolt 4 display via the downstream Thunderbolt 4 port.
- The USB-C upstream port (USB 10Gbps, KVM) provides data and KVM switching but does not supply power delivery — use the Thunderbolt 4 upstream port for charging.
- VESA 100×100mm mount is supported; the stand must be removed before attaching a third-party arm.
- The Thunderbolt 4 downstream port provides only 15W, which is insufficient to charge most modern laptops from that port alone.
Best for
- Creative professionals who need factory-calibrated, wide-gamut colour (99% DCI-P3, Delta E <1.5) for photo editing, video grading or graphic design.
- Laptop users who want a single Thunderbolt 4 cable to carry video, data, and up to 140W charging to keep a high-powered laptop running.
- Multi-device desks where the built-in KVM switch, 2.5GbE, front pop-out hub and eight total USB ports replace a separate dock.
- Long-session users who benefit from TÜV 5-star eye comfort, flicker-free backlighting, an ambient light sensor and a low-reflectance anti-glare panel.
- Buyers who need warranty confidence — Advanced Exchange ships a replacement the next business day after remote diagnosis, and Premium Panel Exchange covers even a single bright pixel.
Trade-offs
- Competitive gaming: a 5ms GTG fast-mode response time and 120Hz ceiling are capable for general use but below what dedicated gaming monitors designed specifically for competitive play offer.
- Buyers expecting USB-C charging without Thunderbolt 4: the USB-C upstream port is data-only for KVM; only the Thunderbolt 4 upstream port supplies power.
- Tight-space desks: at 28.09" wide and up to 24.37" tall with the stand, this is a large monitor that requires substantial depth and width on a workstation.
- Daisy-chaining powered devices from the downstream port: the Thunderbolt 4 downstream port delivers only 15W, limiting what can be powered from it.
Feast your eyes on every fine detail on the world's 1st IPS monitor with stunning 3000:1 contrast ratio.
With 47% deeper blacks versus conventional IPS, a low reflectance panel that improves contrast ratio, smoother visuals on a 120Hz refresh rate and exceptional color accuracy with 99% DCI-P3 and Display P3, every detail of your work pops.
The low reflectance panel reduces glare from outside light sources and improves screen contrast.
TÜV 5-star certified monitor for eye comfort.
Your monitor comes with Advanced Exchange Service. If, after remote diagnosis, a monitor replacement becomes necessary, it will be shipped to you the next business day.
Dell's Premium Panel Exchange (PPE) allows panel replacement on monitors during the Dell Limited Hardware Warranty period even if only one bright pixel is found.
