Head-to-head
Dell U3225QE vs LG 32GR93U: Dell docks a work laptop, LG suits desktop gaming without USB-C power needs
The short answer
Choose U3225QE for a work laptop and a capable Thunderbolt hub. LG 32GR93U suits a desktop gaming setup where USB-C charging and desk docking are unnecessary.
Before you choose
The reasoning and the trade-offs
Compare detail at the actual screen size
U3225QE works out to about 139.9 pixels per inch, versus 139.9 for 32GR93U-B. Their pixel densities are close enough that layout and connection needs are stronger separators.
What this is based on
Pixels per inch = √(width² + height²) / diagonal. Inputs are 3840 × 2160 at 31.5 inches and 3840 × 2160 at 31.5 inches. Published nominal diagonals make these approximate.

Winner by situation
Start with what you need it to do
Connect and charge a work laptop through USB-C
U3225QE supplies the Thunderbolt-centered hub and USB-C laptop video. LG 32GR93U lacks USB-C video and charging.

- Better fit
- LG UltraGear 32-inch 4K 144Hz
- Not suitable
Use a desktop gaming PC
32GR93U provides a 4K gaming screen up to 144 Hz for a separately connected desktop. Dell reaches 120 Hz and adds laptop-docking features.

- Depends
- LG UltraGear 32-inch 4K 144Hz
- Better fit
Need high-power USB-C charging
U3225QE provides up to 140 W USB-C laptop power. LG supplies no USB-C charging, so that requirement needs another power route.

What matters in practice
The differences that matter
Compare detail at the actual screen size
U3225QE works out to about 139.9 pixels per inch, versus 139.9 for 32GR93U-B. Their pixel densities are close enough that layout and connection needs are stronger separators.
How we reached this conclusion
Pixels per inch = √(width² + height²) / diagonal. Inputs are 3840 × 2160 at 31.5 inches and 3840 × 2160 at 31.5 inches. Published nominal diagonals make these approximate.
Separate native detail from game speed
U3225QE draws 8.3 million native pixels per frame and 32GR93U-B 8.3 million. Their refresh ceilings are 120Hz and 144Hz respectively.
How we reached this conclusion
Native pixels = width × height. Refresh interval =1000 / Hz, giving 8.3 and 6.9 ms. These are signal and cadence calculations, not measured frame rates, input lag or pixel response.
Dell uses about 63 mm less stand depth while adding docking
U3225QE stand is 63.12 mm shallower than 32GR93U and supplies the USB-C power route absent on LG.
How we reached this conclusion
278 - 214.88 = 63.12 mm. Dell lists 140W USB-C, LG has no USB-C video or charging.

Meaningful differences
What changes the fit
| What changes | Dell UltraSharp 32 4K Thunderbolt Hub Monitor | LG UltraGear 32-inch 4K 144Hz | Why it matters |
|---|---|---|---|
| Native resolution | 3840 × 2160 | 3840 × 2160 | Operating-system scaling changes usable logical workspace. |
| Panel diagonal | 31.5 in | 31.5 in | A nominal screen class may differ slightly from the measured active diagonal. |
| Maximum refresh | 120Hz | 144Hz | Check the exact input, resolution and overclock conditions. |
| Panel technology | IPS Black | IPS | Panel type alone does not establish a measured color or motion winner. |
| Laptop power | Up to 140W | No USB-C laptop charging | Host, cable and negotiated power profile must support the desired delivery. |
| Chassis width | 713.2 mm | 714 mm | Allow additional room for cables, arms and neighboring equipment. |
| Stand depth | 214.88 mm | 278 mm | The included stand can take more desk depth than the display cabinet. |
What you give up
Every choice has a cost
If you choose Dell UltraSharp 32 4K Thunderbolt Hub Monitor
- The 140-watt ceiling requires a compatible laptop and cable. It does not force every laptop to charge at that rate.
If you choose LG UltraGear 32-inch 4K 144Hz
- DisplayHDR 400 certification should not be mistaken for OLED black levels or a local-dimming specification.
What matters in practice
How to make the call
The screen canvas is almost identical
Both use 31.5-inch 4K panels. Dell concentrates on hub features and IPS Black, while LG concentrates on the gaming connection and motion package.
A laptop setup changes the value calculation
Dell offers up to 140W and USB-C video. LG lacks USB-C video and charging, which can require another dock or several cables.
The stand depth difference is substantial
Dell lists 214.88 mm versus 278 mm on LG. That can leave more keyboard space without reducing panel size.
What this comparison cannot tell you
- Pixel density and refresh intervals are calculations from published specifications, not a measured visual-quality or latency test.
- USB-C power is a maximum negotiated ceiling. It does not promise full-speed charging for every laptop.
