ASUS Ergo ASUS ROG Strix OLED 26.5" 1440p HDR 240 Hz Gaming Review

This 27-inch OLED hits a 97th percentile color score and 240Hz refresh for buttery smooth, vibrant gaming. It's heavy and lacks HDMI 2.1, but for pure speed and visual pop at 1440p, it's hard to beat. Shop smart—prices vary by over $650.

The ASUS ROG Strix XG27AQDMG is a 27-inch OLED gaming monitor that nails the fundamentals. It scores in the 97th percentile for color and the 83rd for performance, which translates to a 1440p panel with a 240Hz refresh rate and a near-instant 0.03ms response time. That's a combo built for speed and visual pop. Our data also shows it's a solid all-rounder, scoring 87+ for office, professional, and total use, though its 9.1/100 portability score means you're not taking this 6.7kg beast anywhere.

This is where the OLED panel really sings. That 97th percentile color score means you're getting 1.07 billion colors (10-bit) and 99% DCI-P3 coverage, which is top-tier for vibrancy and accuracy. The 240Hz refresh rate and 0.03ms GtG response time put motion clarity in the elite category. It's G-Sync Compatible and has FreeSync Premium Pro, so you're covered for smooth gameplay regardless of your GPU. The 450-nit peak brightness and HDR10 support are good, though not class-leading, which is why its display score sits at a still-strong 78th percentile.

The price spread is wild, ranging from $605 to $1258 across different vendors. That's a $653 difference, so shopping around is non-negotiable. At the lower end of that range, this monitor is an absolute steal for an OLED with these specs. At the high end, you're paying a premium for the ROG branding and need to consider if competing 4K or larger OLEDs offer better value for your specific needs.

Compared to the Samsung Odyssey Neo G9 (a 57" mini-LED beast), you're trading sheer size and brightness for OLED's perfect blacks and pixel-level precision at a typically lower price. Against the ASUS ROG Swift 32" 4K QD-OLED, you're choosing between this monitor's higher 240Hz refresh rate for competitive gaming and the Swift's sharper 4K resolution for detail. The LG UltraGear 45" offers an ultra-wide experience but at a lower pixel density. This ASUS sits in a sweet spot: high refresh 1440p OLED with excellent color, making it a killer choice for fast-paced games where motion and contrast matter most.

Skip this if you need a monitor for a bright, sunlit room. The 450-nit peak brightness, while good, isn't in the top tier for fighting glare, and that glossy screen will act like a mirror. Also, if you're a content creator who needs reference-level HDR brightness or a frequent LAN party attendee, that 28th percentile compactness score (read: it's a 6.7kg tank) and lack of HDMI 2.1 are legitimate drawbacks.

If you want arguably the best combination of color, contrast, and speed for competitive and immersive gaming at 1440p, this ASUS ROG Strix OLED is a phenomenal choice. Its percentile rankings back up the hype: elite color, great connectivity and ergonomics, and top-tier motion performance. Just be sure to snag it at a good price from that wide vendor spread, and have a sturdy desk ready for its not-so-portable frame.
