Windows Central Verdict
ASUS has joined the race to create the best sub-$1,000 gaming monitor with the absolute best OLED displays, and the XG27UCDMG delivers with incredible image quality and performance, its excellent OLED care features, and diverse display inputs with KVM support. It's very well-priced, too, but that pricing can be inconsistent depending on where you look, and this isn't the only great 4K, 240Hz OLED display you can find in this price range.

High-end OLED gaming monitors are slowly but surely becoming more accessible to gamers.
ASUS is joining the battle for your wallet's attention with a new 27-inch, 4K, 240Hz OLED gaming monitor that dips below the $1,000 barrier. It just so happens that exact monitor has been on my desk for a few weeks now.
The ASUS ROG Strix OLED 27 (XG27UCDMG) is an exceptional display that goes up against the very best gaming monitors, and it wouldn't be outlandish to describe it as a good value — at least when compared to the other most premium OLED monitors on the market.
As far as I'm concerned, the ASUS XG27UCDMG just became the top 27-inch gaming monitor you can buy, just narrowly beating out the Alienware 27 4K QD-OLED Gaming Monitor (AW2725Q) I recently reviewed.
That's not to say there's nothing I'd change, of course, and the evolving global economy may affect how much you end up paying.
I've been on a spree reviewing the latest and greatest OLED gaming monitors, comparing these premium displays to the absolute best you can buy. Image quality, performance, design, extra features — it all matters, and I'm considering all of it in every review.

ASUS XG27UCDMG review: What I like
Disclaimer: This monitor's biggest competitor is easily the Alienware AW2725Q I mentioned above, so I'll be making regular comparisons.
That starts with the design! ASUS' monitor design language is familiar at this point, and the XG27UCDMG doesn't break the mold in any way. It's a good-looking monitor, but Alienware's new design language is definitely a lot sleeker.
ASUS still brought its A-game here, though. A thorough thermal management solution with a custom heatsink didn't stop ASUS from building the XG27UCDMG's power supply directly into the monitor, so a single cable is all you need to keep the lights on.
The two-piece stand doesn't require any tools to assemble or connect to the monitor, and gives you plenty of height, swivel, tilt, and pivot adjustability. There's even a little indent to prop up your phone below the display.
My favorite part of ASUS monitors is still here, too, and that's the dedicated VESA mount adapter included in the box. You attach this adapter to your standard monitor arm or mount, then you can clip the monitor directly to it (just like the stand works). Need to take it off? A single button press is all you need. Every company needs to steal this idea.
Setting | Brightness | Black | Contrast | White point |
|---|---|---|---|---|
0% | 16.4 | 0 | Infinite | 6,000 (0.323, 0.327) |
25% | 90.8 | 0 | Infinite | 5,900 (0.324, 0.326) |
50% | 164.3 | 0 | Infinite | 5,900 (0.325, 0.327) |
75% | 237.9 | 0 | Infinite | 5,900 (0.325, 0.326) |
100% | 312.5 | 0 | Infinite | 5,900 (0.325, 0.326) |
The display is — once again — largely familiar. The latest generation of Quantum Dot OLED panels, this screen is perfectly crisp at 4K, delightfully smooth at 240Hz, and beautifully responsive at 0.03ms.
It's vibrant and saturated, with bold colors and infinite contrast making every scene pop. ASUS factory calibrates each XG27UCDMG to ensure color accuracy, so it's no wonder this monitor looks as great as it does.
Like the Alienware AW2725Q, this monitor does skew toward the warm side in terms of white balance, but it at least surpasses its promised maximum brightness. There's no Dolby Vision support for High Dynamic Range (HDR) content, but this monitor still looks fine with HDR enabled.
Performance is perfect. I never once encountered any stutters or screen tearing while using the XG27UCDMG, and it adeptly adapted to all my usage scenarios, from productivity work to gaming.
Personally, I also prefer the way ASUS XG27UCDMG's display over the Alienware AW2725Q, as it feels slightly poppier. ASUS also paid attention to the details of its software and hardware features.
For one, you do get a USB Type-C port for connecting to laptops and other modern devices, and it supports 90W Power Delivery. You also get the latest DisplayPort 1.4 and HDMI 2.1 standards, so you have a lot of flexibility when connecting devices.
This enables Keyboard, Video, Mouse (KVM) support with the three USB Type-A ports and 3.5mm audio jack, and there's both Picture-in-Picture and Picture-by-Picture support.
ASUS positioned the joystick and buttons for interacting with the On-Screen Display (OSD) below the screen, and it works well. You can also download the optional DisplayWidget Center for some added control.
You can choose from a wide variety of color profiles, enable monitor-level gaming features like a cross-hair or FPS counter, configure your KVM setup, access the plethora of OLED care features (still love ASUS' dedication to this), and even create custom keyboard shortcuts to adjust your monitor's settings on the fly.
Helpfully, ASUS also built an anti-flicker mode in the XG27UCDMG for those who struggle with sensitivity to Pulse-Width Modulation (PWM), which many OLED monitors use for dimming. It'll disable or restrict some features, but it's great to have as an option.
There's also a proximity sensor built into the logo beneath the display, so the XG27UCDMG can automatically dim itself or go to sleep when you leave your desk and wake up when you return (this helps conserve power and protect the OLED display).
ASUS XG27UCDMG review: What I don't like
There's very little I can complain about with the ASUS XG27UCDMG, so I'll start with the most obvious: the pricing. At around $980, this monitor actually costs more than it was initially supposed to, and the price may be even higher depending on where you shop.
It's still a solid value for an ultra-premium OLED gaming monitor in my eyes, but the Alienware AW2725Q at $900 (and sometimes discounted lower) may be the better deal for you if you don't need KVM support or USB Type-C input.
Elsewhere? I wish this monitor had one more USB port. I wish you could configure the Anti-Flicker mode and Neo Proximity Sensor in the ASUS DisplayWidget Center. More than all of that, I wish I had more control over the color profiles.
There are 10 color profiles from which to choose on the XG27UCDMG, with one being an AI-powered profile that aims to adjust to the content on screen, and the other being a user-customizable profile that lets you tweak the color temperature, saturation, brightness, and contrast.
In the OSD, you also get some additional settings, like choosing the color gamut space or changing the gamma. Unfortunately, ASUS gives you less control over the other color profiles, and none of the color profiles let you adjust effects like the over-the-top sharpening that noticeably impact image quality (hence why I stick with the "User" profile).

ASUS XG27UCDMG review: My final thoughts
✅You should buy this if ...
- You want a top-notch OLED gaming monitor for less than $1,000.
- You need USB Type-C input and KVM support.
- You value having control over all the OLED protection features.
❌You should not buy this if ...
- You want the most affordable 27-inch, 4K, 240Hz OLED gaming monitor.
- You need complete control over every aspect of your display settings.
When I reviewed the Alienware 27 4K QD-OLED Gaming Monitor (AW2725Q), my only complaint was that it felt a little too barebones. Now, we have a comparable monitor with a few extra bells and whistles, and it's amazing.
The ASUS ROG Strix OLED 27 (XG27UCDMG) unfortunately costs a little more than it was originally supposed to, but it's still an excellent display for anyone who refuses to compromise on resolution or refresh rate.
USB Type-C input, 90W Power Delivery, KVM support, a VESA mount adapter, and other add-ons and helpful features make this QD-OLED gaming monitor feel even more premium, and ASUS gives you peace of mind with a 3-year warranty and a wide assortment of customizable OLED protection settings.
You still won't find a built-in webcam, speakers, or some other niche features, but the ASUS XG27UCDMG has earned the highest accolade Windows Central can bestow upon it. Just be wary of where you buy it, as prices may fluctuate thanks to tariffs and other economic shifts.
For the safe bet, you can get the ASUS ROG Strix OLED 27 (XG27UCDMG) for $979.99 at Best Buy.
The ASUS XG27UCDMG just barely pulls ahead of our second favorite 27-inch OLED gaming monitor thanks to the addition of extra features and capabilities, making this one of the best displays you can buy for under $1,000. OLED is still very expensive, but the benefits are worth it.
