I’ll be comparing the EX3210U to a group of 32-inch (one 27-inch) Ultra HD monitors. All run at 144 Hz except the Asus PG32UQ, which can overclock to 155 Hz. The remaining screens are ViewSonic’s XG321UG, Philips’ 329M1RV, HP’s Omen 27u and MSI’s MPG321UR-QDX.
Pixel Response and Input Lag

The MSI is an outlier in this category with a touch quicker response than I’ve recorded from any other 144 Hz monitor. The EX3210U delivers typical performance in this test. With its overdrive set to 1, it maintains good motion resolution with no ghosting visible in test patterns or actual content.
The EX3210U is a tad quicker overall than the others, with 30ms total control lag. Note that the Asus’ 155 Hz offers no advantage here. The BenQ is one of the quickest 4K monitors I’ve tested, making it ideal for high-end PC or console gaming. Of course, there is a much quicker response available at lower resolutions with refresh rates of 240 or 360 Hz. But in the Ultra HD category, this is as fast as it gets.
Viewing Angles
The EX3210U offers good off-axis image quality with only a slight drop in brightness and a shift to red/green. This is typical of the better IPS panels I’ve photographed. A 32-inch monitor is easily shareable for two users playing in a split-screen configuration. The top view is quite washed out and blue.
Screen Uniformity

My EX3210U sample had a bit of glow in the upper right and lower left corners. It was visible in a black field pattern but much harder to see in dark gaming and video content. It did not distract from gameplay. There were no aberrations in brighter content and color was perfectly uniform throughout.
