ASUS ROG Strix XG27ACS 27" Review

This is one of the fastest 1440p gaming monitors you can buy, landing in the 94th percentile for performance. You get 180Hz, 1ms response, and full ergonomic adjustability in a solid package. Its weaker areas are connectivity and color accuracy, but for pure gaming speed, it's a winner.

The ASUS ROG Strix XG27ACS is a 27-inch gaming monitor that puts speed first. With a 180Hz refresh rate and a 1ms response time, it lands in the 94th percentile for performance in our database, making it one of the fastest screens you can buy for the money. It's built for motion clarity above all else.

You're getting a 1440p Fast IPS panel with HDR400 support and a full suite of ergonomic adjustments. Its overall score of 64.4 is solid, with gaming being its clear strength at 70.7. Just don't expect it to be a connectivity hub or a portable companion.

This monitor is fast. Really fast. The 180Hz refresh rate and 1ms response time combo puts it in the top 6% of all monitors we've tested for raw performance. In practical terms, that means buttery-smooth gameplay with minimal ghosting or blur in fast-paced titles. The 1440p resolution is the sweet spot for high frame rates without overloading your GPU.

Its display quality is good, sitting in the 71st percentile. The IPS panel delivers solid viewing angles, and the HDR400 certification adds a bit of pop, though it's not going to compete with more expensive mini-LED or OLED options. Where it stumbles a bit is color accuracy, which is just about average at the 60th percentile. It's fine for gaming and general use, but color-critical work isn't its forte.

The price situation here is... weird. Our data shows vendors listing this from $199 all the way up to a frankly absurd $59,276. Ignore the high-end nonsense. At a realistic street price around the $300-$400 mark, this monitor offers a fantastic price-to-performance ratio for high-refresh gaming. You're paying for that top-tier speed and solid ergonomics, not for premium color or extensive ports. Compared to its direct rivals, it's a compelling option if raw frame rate is your top priority.

Stacked against the competition, the XG27ACS makes its case with pure speed. The LG UltraGear 27" Dual Mode might offer more connectivity options, and the Samsung Odyssey G7 27" has a more aggressive curve and potentially better contrast, but neither typically beat this ASUS on sheer refresh rate at this price. The MSI MAG 27" and BenQ Mobiuz EX271U are often in the same ballpark for performance, so it comes down to design preference and minor feature tweaks. The Dell UltraSharp is a different beast entirely, focused on productivity and color accuracy, not gaming. If your spreadsheet is a first-person shooter, this ASUS wins.

Skip this monitor if you need a ton of ports for a docking station setup. Its connectivity scores in the 31st percentile, meaning it lags behind most monitors. Also, creative professionals who need high color accuracy should look elsewhere, as its color performance is merely average. And if you plan on moving your monitor around a lot, the 6.6kg weight makes it a chore.

If you want a no-compromise, high-refresh 1440p gaming monitor and don't need perfect colors or a ton of ports, the ROG Strix XG27ACS is an easy recommendation. The performance is best-in-class, the ergonomics are great, and at a sane price, it's a fantastic value. Just know what you're getting: a speed demon, not a color-accurate studio monitor or a connectivity hub.
