ASUS ROG Strix 27" 270 Review
The ASUS ROG Strix XG27ACMG proves a gaming monitor can be more than just fast. With 270Hz, excellent color, and a superb stand, it's a true do-it-all screen.
The 30-Second Version
A speedster that doesn't skimp on the basics. With 270Hz, great colors, and a killer stand, it's the rare gaming monitor that's actually good for everything else too.
Overview
The ASUS ROG Strix XG27ACMG is a monitor that makes a promise and actually keeps it. It's a 1440p, 270Hz speed demon wrapped in a surprisingly versatile package. The one thing you need to know is this: it's not just a gaming screen. With its excellent color accuracy and full ergonomic stand, it's a legitimate all-rounder that can handle work and play without breaking a sweat.
Performance
The numbers don't lie. This thing is fast. A 270Hz refresh rate and 1ms response time put it in the 97th percentile for performance in our database, which means it's in the elite tier for competitive gaming. But what surprised us was how good it looks doing it. That 95% DCI-P3 color coverage is no joke. You get buttery smooth motion and rich, vibrant colors, which is a combo you don't always find at this speed.

Value & Pricing
With prices swinging from $223 to $399 depending on the vendor, the value proposition is entirely about the deal you find. At the lower end of that range, it's an absolute steal. At the high end, you're starting to bump into more feature-rich competitors. Shop around.
vs Competition
This monitor sits in a sweet spot. Compared to a pure esports monitor, it offers much better color and ergonomics. Compared to a high-end creative display, it offers way more speed. The most direct competitor is likely another 1440p high-refresh-rate IPS panel, like something from LG's UltraGear line. The ASUS fights back with its better stand and USB-C port. If you're eyeing the Samsung Odyssey or ASUS's own QD-OLED, know that you're trading pure pixel response and contrast for this monitor's lower price and lack of burn-in risk.

Common Questions
Q: How big is this thing with the stand?
It's about 20 inches wide, 24 inches tall, and 8.6 inches deep. It's a standard 27-inch footprint, but that full-adjustable stand does add some height.
Q: Is it really 270Hz?
Yep, 270Hz is the spec. You'll need a beefy GPU and to use the DisplayPort or USB-C connection to hit that max refresh rate at 1440p.
Q: Can I use this with my laptop?
Absolutely, and the USB-C port is the key. It handles video, audio, and can even deliver 15W of power back to your laptop, which is enough to slow a drain or charge a smaller device.
Who Should Skip This
If you're a hardcore HDR enthusiast or a video editor who needs reference-grade color, this isn't your monitor. Look at a Mini-LED or OLED panel instead. Also, if you only play slow-paced single-player games, you're paying for speed you'll never use—grab a high-resolution 4K screen instead.
Verdict
If you want a single monitor that can genuinely do it all—crush competitive games, handle content consumption, and even do some color-accurate work—this is a fantastic choice. It's a jack-of-all-trades that's a master of speed. We recommend it, especially if you can snag it on sale.
