Uncalibrated – Maximum Backlight Level
The GS27QXA is up with the brightest 27-inch QHD screens in its price category. The Xiaomi rides quite a bit higher thanks to its Mini LED backlight. That extra output will cost you around $100 more though. 433 nits is more than enough for any indoor environment and is sufficient for outdoor use in a shaded area like a location video production tent.
Black levels are respectable at 0.3250 nit, resulting in a solid 1,334.2:1 static contrast ratio. This is comfortably above the IPS average of 1,000:1. Note that the G Pro 27i was tested with its zone dimming turned off so all screens above are showing their native contrast performance.
After Calibration to 200 nits
Calibration barely affects the results with no visual change to dynamic range. The GS27QXA remains in third place for both black levels and contrast. This kind of consistency is a very good thing. In the ANSI test, the ratio drops slightly to 1,255.9:1 and still sits in third place. Among IPS monitors, this is excellent performance.
Test Takeaway: At around 1,300:1, the GS27QXA has above average contrast for an IPS monitor. For $269, you won’t do much better. It has higher brightness than most of its competition as well. The value quotient here is quite high.
