The catch
Dell UltraSharp 32 4K Thunderbolt Hub Monitor
Compared with the 27-inch UltraSharp, the 31.5-inch panel takes up more desk width.
Side by side
Take the U3225QE for a work laptop and a capable Thunderbolt hub. If you have a desktop gaming setup with no need for USB-C charging or desk docking, the LG 32GR93U suits.
Before you buy
U3225QE is about 139.9 pixels per inch, and 32GR93U-B is 139.9 too. The pixel densities are close enough that layout and connection needs are the stronger separators.
Where this comes from
Pixels per inch = √(width² + height²) / diagonal. The inputs are 3840 × 2160 at 31.5 inches and 3840 × 2160 at 31.5 inches. Because the diagonals are published nominal values, these figures are approximate.
The catch
Compared with the 27-inch UltraSharp, the 31.5-inch panel takes up more desk width.
The catch
Unlike a docking monitor, it offers no USB-C video or laptop charging.

A work laptop and a capable Thunderbolt hub point to the U3225QE. The LG 32GR93U suits a desktop gaming setup where USB-C charging and desk docking are unnecessary.
The screen canvases are nearly the same
Which one fits
The Thunderbolt-centered hub and USB-C laptop video come with U3225QE. LG 32GR93U has no USB-C video or charging.
For a separately connected desktop, 32GR93U provides a 4K gaming screen up to 144 Hz. Dell reaches 120 Hz and adds laptop-docking features.
Up to 140 W of USB-C laptop power is provided by U3225QE. LG supplies no USB-C charging, so that requirement needs another power route.
Dell stops at 120 Hz, while LG reaches 144 Hz at 4K. Confirm that the source and connection support the intended 4K timing.
In practice
U3225QE is about 139.9 pixels per inch, and 32GR93U-B is 139.9 too. The pixel densities are close enough that layout and connection needs are the stronger separators.
Pixels per inch = √(width² + height²) / diagonal. The inputs are 3840 × 2160 at 31.5 inches and 3840 × 2160 at 31.5 inches. Because the diagonals are published nominal values, these figures are approximate.
U3225QE draws 8.3 million native pixels per frame, and 32GR93U-B draws 8.3 million as well. Refresh ceilings are 120Hz and 144Hz respectively.
Native pixels = width × height. Refresh interval =1000 / Hz, so the results are 8.3 and 6.9 ms. They are signal and cadence calculations and not measured frame rates, input lag or pixel response.
Besides supplying the USB-C power route absent on LG, the U3225QE stand is 63.12 mm shallower than 32GR93U.
278 - 214.88 = 63.12 mm. Dell lists 140W USB-C, and LG has no USB-C video or charging.

Dell, U3225QE
On a desk where you want fewer separate boxes, this larger 4K work screen offers 120Hz scrolling, 140-watt charging and a Thunderbolt hub.

LG, 32GR93U-B
Games get more physical room on this flat 32-inch 4K screen, and there are plenty of pixels left for work. A 144Hz panel and HDMI 2.1 inputs make it a simple choice for both PC and console.
Spec by spec

|---|---|---|---|
| Native resolution | 3840 × 2160 | 3840 × 2160 | Usable logical workspace changes with operating-system scaling. |
| Panel diagonal | 31.5 in | 31.5 in | The measured active diagonal may differ slightly from a nominal screen class. |
| Maximum refresh | 120Hz | 144Hz | Look at the exact input, resolution and overclock conditions. |
| Panel technology | IPS Black | IPS | A measured color or motion winner is not established by panel type alone. |
| Laptop power | Up to 140W | No USB-C laptop charging | For the desired delivery, the host, cable and negotiated power profile all have to support it. |
| Chassis width | 713.2 mm | 714 mm | Leave additional room for cables, arms and neighboring equipment. |
| Stand depth | 214.88 mm | 278 mm | More desk depth can be taken by the included stand than by the display cabinet. |
Trade-offs
Decision guide
The U3225QE is for a work laptop and a capable Thunderbolt hub. The LG 32GR93U is for a desktop gaming setup where USB-C charging and desk docking are unnecessary.
31.5-inch 4K panels are used in both. Dell puts its effort into hub features and IPS Black, LG into the gaming connection and motion package.
Up to 140W and USB-C video come with the Dell. The LG has neither USB-C video nor charging, which can mean another dock or several cables.
Dell lists 214.88 mm, against 278 mm for LG. That can leave more keyboard space without shrinking the panel.
