BenQ MOBIUZ EX271U 27" White

The BenQ MOBIUZ EX271U is a 27-inch 4K gaming monitor with a 165Hz refresh rate, fantastic connectivity, and a built-in KVM for work-play setups. Colors are vibrant and text is pin-sharp. Just budget for external speakers and don't expect mind-blowing HDR.

A 27-inch 4K monitor that actually makes sense outside of pure gaming is kind of rare. The BenQ MOBIUZ EX271U swings hard in that direction, packing a 3840x2160 IPS panel, a 165Hz refresh rate, and a KVM switch that turns it into a proper work hub. If you've been hunting for a high-refresh 4K display that can handle spreadsheets and RGB-lit shootouts with equal grace, this one deserves a spot on your shortlist.

BenQ loaded the EX271U with connectivity that frankly puts most competitors to shame. Three HDMI 2.1 ports, a DisplayPort 1.4, and a USB-C port with 65W power delivery mean you can hook up a gaming PC, a console, and a work laptop without ever touching a cable. The 95% DCI-P3 coverage and 400-nit brightness won't set any HDR records, but the colors pop enough to make games and animated content look lively. And at around $400 from some retailers, it undercuts the OLED crowd by a fair margin while dodging burn-in anxiety.

It's not perfect. The lack of built-in speakers is a letdown, and the stand is chunky enough to eat into desk space. But for people who want one monitor to rule both work and play, the EX271U makes a compelling case.

Spec sheets don't always tell the full story, but here the numbers paint a pretty clear picture. The 165Hz refresh rate and 1ms GtG response time place this monitor solidly above average, around the 78th percentile across all monitors we track. That's more than enough for smooth gameplay in everything from fast-paced shooters to sprawling RPGs. You won't get the insane motion clarity of a 240Hz OLED, but you also won't deal with VRR flicker or burn-in paranoia.

Real-world use backs up the numbers. FreeSync Premium keeps tearing at bay, and the IPS panel holds its own in bright rooms where OLEDs sometimes struggle. Colors look accurate enough for photo editing with a quick mode switch, and the 4K resolution makes text razor-sharp, which is a godsend for coding or reading long documents. The 400-nit peak brightness isn't thrilling for HDR movies, but for SDR content and everyday gaming it's more than serviceable.

Pricing on the EX271U is all over the place. Newegg currently lists it at the low end around $400, while other vendors have it floating for as much as $107,206 (clearly a listing error, but still, double-check before you buy). At the $400 mark, it's aggressively priced for a 4K 165Hz IPS display with this much connectivity. Yes, OLED alternatives like the MSI MAG 272UP QD-OLED start around $600 to $700 and deliver way better contrast and HDR. But if you need a monitor that pulls double duty for work and play without the slightest risk of burn-in, the BenQ undercuts those options meaningfully while matching their refresh rate.

Stacked against the OLED horde, the EX271U plays a different game. Monitors like the ASUS ROG Strix XG27AQDMG, MSI MAG 272UP QD-OLED, and Samsung Odyssey OLED G6 all deliver perfect blacks and higher HDR brightness. If you're mostly gaming in a dark room and you want that cinematic wow factor, any of those will look more impressive. But they also run at a lower 1440p resolution in the same 27-inch size, so text won't be as sharp, and they all carry the long-term risk of burn-in if you leave static windows open for hours.

For a productivity-heavy user, the BenQ's 4K pixel density and IPS longevity are genuine advantages. You lose the infinite contrast, but you gain a KVM switch that none of those OLED monitors offer in the same price bracket. The LG UltraGear 27GX790A-B is a closer match in terms of connectivity and refresh rate, but it's also an OLED and pricier. If you want one screen that handles work during the day and games at night without compromise, the EX271U earns its keep against those flashier alternatives.

If you're chasing the deepest blacks and most cinematic HDR for gaming or movies in a dark room, skip this. The IPS contrast just can't compete with OLED monitors like the Alienware AW3423DWF or Samsung Odyssey OLED G6. Competitive gamers who prioritize frame rates over resolution should also look elsewhere since you can get 240Hz 1440p OLEDs for similar money. And if you need a portable monitor, this heavy 27-inch panel with a bulky stand is obviously the wrong tool.

Should you buy this? If you're a remote worker who games after hours and you're dead set on a 4K monitor with a high refresh rate, the BenQ MOBIUZ EX271U is about as good as it gets right now. The KVM feature alone can save you from buying a separate USB switch, and the sheer number of ports means you won't have to juggle cables. It's a monitor that genuinely simplifies a mixed setup.

Just know what you're trading away. The lack of built-in speakers is a hassle if you don't already have a headset or desktop speakers, and the HDR performance is forgettable. But if none of that bothers you and you want a crisp, color-accurate panel that handles both your work dashboard and your game library without fuss, this is an easy recommendation at its real-world street price.
