Uncalibrated – Maximum Backlight Level
We’ve rounded up the fastest monitors from recent reviews to compare the Predator X25’s performance. At 360 Hz is the Alienware AW2521H and Asus ROG Swift PG259QN. At 280 Hz is Asus’ TUF VG259QM. Running at 240 Hz are the Aorus FI25F and BenQ XL2546K. All are IPS panels, except the BenQ, which is TN and has the best blur reduction feature we’ve ever seen.
Once we turned the Max Brightness option on, we were able to top out the X25 at over 447 nits. Otherwise, it’s limited to around 225 nits. That’s plenty of light for any environment and compares favorably with the other screens in our comparison group.
The X25’s black levels are higher than average, even for the latest Fast IPS panels, which have a bit less contrast than their slower, standard IPS cousins. But the X25's resulting contrast is fair at 934.1:1. Note that Asus manages to squeeze out an impressive 1,265:1 from its 360 Hz monitor.
After Calibration to 200 nits
Our calibration (see recommended settings on page one) boosted the X25’s standing in the black level and contrast tests from fifth to fourth place. The 360Hz Asus monitor, however, offers the best native contrast by around 20%.
ANSI contrast after calibration is at the same level as the static value, which speaks well to the X25’s build and quality control. Ultimately, these monitors are about speed, but if you’re looking for the small differences, contrast performance is the most visible metric.
