To compare the FO27Q5P’s performance, I’ve harvested five other speedy 27-inch QHD OLEDs from my database that range from 280 to 500 Hz. There’s Asus’ most recent addition to its Strix line, the XG27AQDPG, along with LG’s 27GX790A, Samsung’s OLED G6, Philips’ 27M2N8500 and Alienware’s AW2725D.
Pixel Response and Input Lag
On planet LCD, you’ll see smoother motion at 500 Hz than you do at 280. This is not true of OLED, in my observation. Once you get to 240 Hz, motion resolution is perfect, in that it is indistinguishable from static. That’s something you can easily see in a moving test pattern. Regardless, the 2ms it takes for the Aorus and Asus screens to draw a full white field is impressive. Visually, all the monitors look the same at 280fps or faster.
Input lag is a more significant decider, and there, the Philips and LG displays still maintain their dominant 10ms score in my test. The FO27Q5P may seem far down the pack at 18ms, but in practice, I cannot see a difference in response between any of them. Gaming pros will want the absolute fastest monitor and that is still the Philips or LG. But anyone playing on the Aorus will be happy as a clam. It’s super quick. I also noted its complete lack of artifacts when using the Ultra Clear option at lower frame rates.
Test Takeaway: The FO27Q5P stands out not for its 500 Hz but for its superb black frame insertion feature, Ultra Clear. It’s the perfect solution for game systems that can’t run QHD resolution faster than 200fps. If you have the horsepower, GeForce RTX 4090 or better, the higher refresh rates deliver some headroom. But the quickest overall screens are still the Philips 27M2N8500 and the LG 27GX790A.
Viewing Angles
You wouldn’t know that the FO27Q5P is a Quantum Dot display from these photos. That tech sometimes causes a slight color shift at 45 degrees, but Aorus avoids that anomaly. I saw no change in color, luminance or gamma. The top view is slightly dimmer and a tad red with reduced gamma, but you can still see all the brightness steps. This consistency at multiple viewing angles is one of the principal reasons to buy an OLED.
Screen Uniformity

The newest generation of OLED monitors has excellent screen uniformity. I’m impressed by anything that comes in under 10%, but look at the top five screens here; they’re all below 4%. And the FO27Q5P tops them all at an impressive 1.31%. This is excellent performance.
