Acer AOPEN 27HC5UR S 27" Curved Gaming Monitor | Review

For around $180, this is one of the most feature-packed gaming monitors you can buy, scoring in the 97th percentile for specs. You get a 165Hz QHD curved VA panel with a fully adjustable stand and HDR10. Just know that its panel performance is solid, not spectacular, and always check the seller—prices can be ludicrously inflated.

The Acer AOPEN 27HC5UR S is a 27-inch curved gaming monitor that hits a sweet spot for features. It packs a 165Hz refresh rate, QHD (2560 x 1440) resolution, and AMD FreeSync Premium into a package that, at its best price, is a serious bargain. Our scoring puts its overall feature set in the 97th percentile, which is one of the best we've seen, but its core performance and display quality land in a solid, middle-of-the-pack range around the 70th percentile.

That feature score tells the main story: you're getting a lot of monitor for your money. It has height adjustment, VESA mounting, and HDR10 support, which are often cut from budget models. The 1500R curve adds to the immersion, though it's a love-it-or-hate-it design choice. Just be aware that the price you see online can vary wildly, from a sensible $179 to an absurd $47,000, so shopping around is non-negotiable.

For gaming, this monitor delivers a strong, if not chart-topping, experience. The 165Hz refresh rate and 1ms response time (likely MPRT) provide smooth motion that's well above the 60Hz standard, landing its performance score in the 70th percentile. Paired with AMD FreeSync Premium, it effectively eliminates screen tearing without needing an expensive G-Sync module. The QHD resolution on a 27-inch screen is the right fit, offering a nice bump in sharpness over 1080p without demanding a top-tier GPU.

The VA panel offers good contrast for darker scenes, but its color performance, also in the 70th percentile, is just solid. It supports HDR10, but don't expect the eye-searing brightness of a premium HDR display. It's a nice-to-have feature that improves the dynamic range over SDR, but it's more of a bonus than a headline act. For fast-paced shooters or immersive single-player games, it gets the job done reliably.

The value proposition here is entirely dependent on which price you find. At around $179, this monitor is a steal, offering a feature set that humiliates other screens in that price bracket. The moment you see it listed for hundreds or thousands more, walk away. That massive $46,882 price spread is insane and usually a sign of third-party sellers taking advantage of stock fluctuations. For the right price, you get a high-refresh QHD curved screen with premium ergonomics, which is a combo that's tough to beat.

Stacked against its peers, the AOPEN's strength is its budget-friendly features. The LG UltraGear 27" might offer a faster IPS panel, but you'll pay more for similar adjustability. The Samsung Odyssey G7 27" has a much higher 240Hz refresh rate and better contrast, but it also costs significantly more. The ASUS ROG Strix and MSI MAG models often compete directly on price but might skimp on the full ergonomic stand. The BenQ Mobiuz EX271U is a strong all-rounder with better color out of the box, but again, at a higher cost. If your budget is tight and you want a full package (stand, curve, QHD, high refresh), the AOPEN at its low price is the play. If pure panel quality or max refresh rate is your goal, those other monitors are worth the extra cash.

Skip this monitor if you're a competitive esports player chasing every last frame. Its 165Hz refresh is great, but models like the Samsung Odyssey G7 offer 240Hz for a true edge. Also, avoid it if you need perfect color accuracy for professional photo or video editing. The VA panel's viewing angles and factory calibration aren't suited for critical color work. Finally, if you frequently share your screen with someone looking over your shoulder, the curve and VA viewing angles will make the image look washed out to them.

If you can snag the AOPEN 27HC5UR S for close to $180, it's an easy recommendation for a budget-conscious gamer who wants a fully-featured, immersive setup. You're getting a 97th-percentile feature list for a song. The trade-off is that you're getting a good, not great, panel. The performance is smooth and capable, but don't buy it expecting the absolute best color accuracy or mind-blowing HDR. For the price, those compromises are more than fair. Just buy from a reputable seller with a good return policy, given the scattered reports about longevity.
