The G Pro 27i’s comparison group is a mix of edge-lit and Mini LED panels running from 165 to 200 Hz. We have Asus’ XG27ACS, ASRock’s PG27QFT2A, Cooler Master’s GP2711 and GP27Q and ViewSonic’s XG341C-2K.
Pixel Response and Input Lag

The G Pro 27i’s 180 Hz delivers a quick panel response of 6ms with the overdrive maxed. This is one of the few monitors that hits a perfect balance of blur reduction without ghosting artifacts. The overdrive speeds are subtly different, but Fastest is the best choice if you’re running at 180fps.
Input lag usually goes hand in hand with refresh rate, but the G Pro 27i makes more of its 180 Hz than the competition. Most notably, the 200 Hz ViewSonic is 7ms behind the Xiaomi, which is tied for the lead here with ASRock. This is a very quick monitor that is completely qualified for esports competition.
Test Takeaway: The G Pro 27i is one of the fastest monitors you can buy for under $400. It has a superb overdrive which keeps motion resolution high. QHD means you won’t need a super expensive video card to achieve high frame rates. There’s no backlight strobe but with video processing this good, it’s completely unnecessary.
Viewing Angles
In my off-axis photos, the G Pro 27i performs like a typical IPS panel. There’s a slight shift to red and green at 45 degrees to the sides but no apparent reduction in brightness. The top view shows reduced gamma and a blue tint with about 50% less light output.
Screen Uniformity

The G Pro 27i demonstrates decent quality control with visually perfect screen uniformity. The black field pattern shows a slight hotspot to my meter in the upper right, but I could not see a problem when I turned off the lights. With four tiny LEDs in each zone, that’s 4,608 lights to manage. Color me impressed.
