BenQ MOBIUZ BenQ MOBIUZ EX271U 27" 4K HDR 165 Hz Gaming Review

This 27-inch 4K/165Hz monitor scores in the 90s for color, connectivity, and performance. You get excellent specs for under $450, including USB-C with 65W charging. Just note the user satisfaction scores are mixed, so consider the source.

The BenQ MOBIUZ EX271U is a 27-inch 4K monitor that scores in the 90s for gaming and entertainment in our database. That's a strong start. It packs a 165Hz refresh rate, 1ms response time, and FreeSync Premium into a white chassis with full ergonomic adjustability. For the price, you're getting a feature set that lands in the 93rd percentile for performance and the 94th for connectivity. That includes a USB-C port with 65W charging, which is a nice touch for a clean desk setup.

Our data shows this monitor excels in specific areas: color accuracy hits the 95th percentile, and its display quality overall is in the 92nd. It's clearly built for immersive, smooth visuals. But there's a catch: its social proof score sits at the 36th percentile, which suggests user experiences have been mixed. We'll dig into why that might be.

Let's talk numbers. A 4K panel at 165Hz is no joke, and it puts this monitor's raw performance in the 93rd percentile. That means smoother gameplay and less motion blur than the vast majority of monitors we track. The 400-nit brightness and HDR10 support are solid for the price, though not class-leading. Where it really shines is color, scoring in the 95th percentile. For games and movies, that translates to rich, accurate visuals straight out of the box.

Connectivity is another high point at the 94th percentile. You get HDMI 2.1, DisplayPort 1.4, and that handy 65W USB-C port that can power a laptop and handle video/data. The built-in KVM switch and USB hub are practical features that push its 'feature' score to the 84th percentile. So, on paper, the specs deliver. The 1ms GtG response time and FreeSync Premium should handle fast-paced gaming without major ghosting or tearing.

Priced between $360 and $440, the EX271U sits in a competitive spot. You're paying for that 4K/165Hz combo, premium connectivity, and strong color performance. The value proposition is clear: get near-top-tier specs for color and connectivity without stepping into the $500+ territory of mini-LED or OLED monitors. Compared to a basic 4K/60Hz office monitor, the gaming performance uplift is massive. But, you could find a 1440p/240Hz panel for similar money if pure speed is your goal.

Stacked up, the choices get interesting. The ASUS ROG Swift 32" QD-OLED offers better contrast and HDR for more money, but it's 1440p, not 4K. The Samsung Odyssey Neo G9 is an entirely different beast (massive, ultrawide) at a much higher price. A closer competitor might be a 4K/144Hz model from LG or MSI. The BenQ's key differentiators are its USB-C/KVM features and that 95th-percentile color accuracy. If you need a single cable for your laptop and great color for under $450, this BenQ has an edge. If you want the absolute best HDR or the highest possible refresh rate, you'll need to spend more or look at 1440p.

Skip this if you're chasing the absolute best HDR experience or the highest possible refresh rate. Its 400-nit brightness, while good, isn't in the top tier for HDR impact. Also, if user reviews and brand reputation are your top concern, the 36th percentile social proof score is a red flag. Look at models from ASUS, LG, or MSI with more established track records in gaming monitors if consistency is key.

The BenQ MOBIUZ EX271U is a spec-sheet winner that delivers excellent 4K gaming performance and workstation-friendly features at a reasonable price. The data doesn't lie: 93rd percentile performance, 95th percentile color, and 94th percentile connectivity make a compelling case. We recommend it if your priorities are high-resolution smoothness, accurate colors, and a clean desk setup with USB-C. Just go in aware that its middling social proof score suggests some units or experiences may be hit-or-miss, so buy from a retailer with a good return policy.
