The BenQ MOBIUZ EX321UX is a 32-inch 4k Mini LED gaming monitor. It competes with other 32-inch Mini LED monitors like the ASUS ROG Swift PG32UQX, the Acer Predator X32 FP, and the ViewSonic Elite XG321UG. It's a significant improvement over its predecessor, the EX3210U, which has just 16 local dimming zones. The newer EX321UX has 1,152 zones and has several additional features, such as DisplayPort 2.1 support, USB-C connectivity with 65W of power delivery, and a KVM switch. It also comes with a wireless remote to control the monitor's settings, an ARC/eARC port to connect to soundbars or receivers, and a light tuner setting to increase the brightness of dark shadows.
Our Verdict
The BenQ MOBIUZ EX321UX is good for PC gaming. Its 144Hz refresh rate and low input lag create a fairly responsive feel, and its great motion handling makes fast-moving objects look crisp. Additionally, if you enable local dimming its contrast is excellent, though deep blacks appear gray when it's off. Additionally, it gets extremely bright, and easily overcomes glare and makes highlights pop. It also displays a wide range of colors quite vividly.

The BenQ MOBIUZ EX321UX is impressive for office work. It has superb text clarity and image sharpness. Additionally, it has adequate reflection handling and exceptional brightness, so it works extremely well in a bright environment. However, while it has good height adjustment, it doesn't swivel very much, so it's not ideal if you plan to share your screen with others.

The BenQ EX321UX is great for editing. Because of its 4k resolution images and text look quite sharp. It also displays a wide range of colors in SDR and HDR quite vividly. And while deep blacks appear gray without local dimming, it has excellent contrast when local dimming is on, though it causes a bit of blooming. It also gets bright enough to pop in HDR and has very little ambient black level rise in a bright room, so it's great for editing dark parts of scenes in bright environments. However, it doesn't swivel very much, so it's not great for sharing work with a colleague.

Differences Between Sizes And Variants
We tested the BenQ MOBIUZ EX321UX, the first BenQ model to offer Mini LED dimming. As you can see below, BenQ has two similar models without Mini LED dimming. However, the non-mini LED models are different monitors, and the results are only valid for the MOBIUZ EX321UX.
| Model | Size | Resolution | Max Refresh Rate | Local Dimming System |
|---|---|---|---|---|
| MOBIUZ EX321UX | 32" | 4k | 144Hz | Mini LED Full-Array |
| MOBIUZ EX3210U | 32" | 4k | 144Hz | Edge-Lit |
| MOBIUZ EX2710U | 27" | 4k | 144Hz | Edge-Lit |
Our unit's label indicates it was manufactured in July 2024. You can see a photo of its label here. It was tested with firmware V5.
Popular Monitor Comparisons
The BenQ MOBIUZ EX321UX is a 32-inch 4k Mini LED gaming monitor. It's an outstanding choice for someone who wants a 32-inch monitor for work and gaming, and doesn't want to worry about the risk of burn-in that can come with OLEDs when used for work. It's extremely versatile, as it displays fairly deep blacks if you use its local dimming system, has great motion handling, and displays a wide range of colors quite vividly. It also has excellent connectivity. However, its standout feature is its performance in bright environments. It gets bright enough to easily overcome any glare and make highlights pop, and it has very little ambient black level rise in bright environments.
That said, these capabilities come with a premium price, and the Acer Nitro XV275K P5biipruzx also offers very similar gaming and work performance in a 27-inch size for considerably less money. Additionally, if you only plan to use your monitor for gaming, you can find 32-inch OLEDs with better motion handling and deeper blacks for a similar price, such as the MSI MPG 321URX QD-OLED. However, if you're looking for a 32-inch monitor that works equally well for productivity, editing, and gaming, the BenQ MOBIUZ EX321UX is a fantastic option.

The Samsung Odyssey Neo G8 S32BG85 and the BenQ MOBIUZ EX321UX are 32-inch 4k Mini LED gaming monitors. The BenQ is the better option for most people, as it has more vivid colors, very little VRR flicker, wider viewing angles, and much better connectivity. However, you may prefer the Samsung if you game in a dark room, as it has much better contrast. It also feels more responsive because of its higher 240Hz refresh rate.
The ASUS ROG Swift OLED PG32UCDP and the BenQ MOBIUZ EX321UX are both 32-inch 4k gaming monitors. The ASUS is a better option if you're planning to use your monitor mainly for gaming, as it has a higher refresh rate, much better contrast in a dark room, and far better motion handling. However, the BenQ is a better option if you plan on using your monitor for work as well as gaming, as it has no risk of burn-in, and is far better at overcoming glare.
The Acer Nitro XV275K P3biipruzx and the BenQ MOBIUZ EX321UX are both 4k Mini LED gaming monitors. Both monitors have largely similar motion handling, HDR brightness, and color vividness, and are excellent options if you plan on gaming and working on the same monitor. The biggest difference between them is their size. The Acer is a better choice if you prefer a 27-inch display or are looking for a monitor in a lower price category. However, the BenQ is a better choice if you want a 32-inch display.
The MSI MPG 322URX QD-OLED and the BenQ MOBIUZ EX321UX are 32-inch 4k gaming monitors. The BenQ is a better option if you plan on using your monitor for work quite a bit, as it has no risk of burn-in, sharper text, and is far better at overcoming glare. The MSI is a better option if you plan to do mostly gaming, as it has far better motion handling, a higher refresh rate, and much better contrast in a dark room.
We buy and test more than 30 monitors each year, all of which we purchase ourselves, without cherry-picked units or samples. We put a lot into each unbiased, straight-to-the-point review, and there's a whole process from purchasing to publishing, involving multiple teams and people. We do more than just use the monitor for a week; we use specialized, custom tools to measure various aspects and deliver objective, data-driven results. We also consider multiple factors before making any recommendations, including the monitor's cost, its performance compared to the competition, and whether it's easy to find.
