Uncalibrated – Maximum Backlight Level



The Raptor 27 exceeds its 360-nit rating by 9 nits, making it plenty bright enough for any application. This is for SDR content; HDR brightness is higher as you’ll see in our tests on page five. Black levels are slightly above average, which makes static contrast a tad below average at 942.3:1. There is no dynamic contrast feature available in SDR mode. Note that if you use the blur reduction feature, light output is reduced by 60%.
After Calibration to 200 nits



Calibration improves contrast by a tiny amount, but it’s still a shade under 1,000:1, putting it in fifth place here. The MSI’s VA panel offers nearly 3,000:1 contrast, which is typical of the VA monitors we’ve tested. The Raptor 27 somewhat makes up for its average dynamic range with very saturated and accurate color.
In our intra-image contrast test, the Raptor 27 elevates its status a bit with a solid 1,017.7:1 score. This speaks to its quality control and component selection, with a precisely fitted grid polarizer. In practice, the image is very well saturated and colorful, with black levels near those of other premium IPS screens.

Christian began his obsession with tech when he built his first PC in 1991, a 286 running DOS 3.0 at a blazing 12MHz. In 2006, he undertook training from the Imaging Science Foundation in video calibration and testing and thus started a passion for precise imaging that persists to this day. He is also a professional musician with a degree from the New England Conservatory as a classical bassoonist which he used to good effect as a performer with the West Point Army Band from 1987 to 2013.
