Conclusion

With new speedy OLED gaming monitors appearing on almost a weekly basis, you’d think prices would drop more quickly. Sadly, this hasn’t happened but that doesn’t mean the category lacks value. The image quality and gaming performance offered is simply next level. The only thing other technologies can boast is higher brightness, but nothing can beat OLED’s black levels and contrast.

LCD can’t match OLED’s video processing smoothness and low input lag either. All the examples I’ve tested were super smooth and had no perceptible delays in control response. And you don’t need to run at dizzying frame rates to eliminate motion blur. 360 Hz is more than enough. The Asus ROG Strix XG27ACDNG stands above the 240 Hz rank and file with its 360 Hz and perfect Adaptive-Sync. And it offers the options of ELMB strobing and OLED Flicker compensation.

To this wonderful goodness, it adds some of the best color I’ve ever seen. Not only does it cover 111% of DCI-P3, making it the most colorful OLED I’ve yet tested, it’s unfailingly accurate as well, as in equal to or better than any professional screen. And it nailed those numbers right out of the box, no calibration needed. It’s so good that I couldn’t make even the smallest improvement.

So, you’ve got a stunning image, unparalleled gaming performance and perfect color. The Asus ROG Strix XG27ACDNG has no flaws of consequence. Does that make it expensive at $700? Compared to the broad scope of 27-inch gaming displays, yes. But you’re getting one of the best gaming monitors available and there are certainly more expensive examples that don’t perform as well. If you want the best in a 27-inch flat OLED, this one should be on your shortlist.
