Prime Day just cut this 240Hz QD-OLED monitor to its its lowest price this year
Prime Day may be Amazon’s biggest sale event outside of November’s Black Friday and December’s Cyber Week. So it shouldn’t be a surprise to see the best prices emerge. And we’ve spied one for a top-class QD-OLED at its cheapest this year.
The AOC Agon PRO 27-inch QD-OLED Gaming Monitor is back down to a price not seen since 2025, at $400. That’s a $100 drop from the list price for a monitor that has plenty to offer gamers looking for an upgrade.
Why we like the AOC Agon PRO AG276QZD2
Excellent for gaming
This 27-inch monitor has a 240Hz refresh rate with a lightning-quick 0.03ms response time. As a 2K monitor, you can play in 1440p with native support up to 240 frames per second. That’s plenty for many mid-range gaming setups. Plus, it offers 120Hz consoles.

OLED quality
As an OLED monitor, you can expect stunning visuals, including vibrant colors, deep blacks, and impressive contrast. This monitor has more than enough coverage for the entire DCI-P3 color gamut and sRGB. And that means scenes can look super-immersive.
Height adjustable
There’s little point in having a high-performance monitor if the stand cannot be adjusted for users to view it comfortably. Fortunately, the AOC Agon PRO AG276QZD2 27-inch checks that box, so you can adjust it as needed.

What to consider before you buy
Features are key for monitors, so we’d advise comparing specs sheets and prices across several models. You can also look at our best gaming monitors guide for more information and further context. One thing not to miss is that this monitor has a glossy panel. That’s not to say the quality isn’t high, but positioning is important to avoid potential glare for such a monitor.
