You definitely know the ROG Zephyrus gaming line by Asus well, as we only recently brought you a test of the top-notch model Duo 15. The Zephyrus line started with one product, but today several models bear this tag. One of them is the M15 which, however, has little in common with the original Zephyrus. On the outside, it looks like a regular laptop without gimmicks in the form of a secondary display or the AAS.
Gamut, brightness and deviation
We measured image properties of the display using the Datacolor Spyder5Elite probe. It looks like the M15 got the same panel as the Duo 15, at least in the tested configuration. It is a 15.6″ IPS display with a resolution of 4K in an aspect ratio of 16:9 (3840 × 2160 px) and 60 Hz. It can also boast of 100% coverage of AdobeRGB and Pantone Validation. This panel is the highest in the offer and focuses mainly on graphic artists, designers, etc. Unlike the Duo 15, we will not find G-Sync here. A 240 Hz 3 ms Full HD panel will be more suitable for gamers.
The display pleases with thin frames on three sides, although the lower chin is also relatively large here. 4K resolution is extremely sharp at 15 inches, even impractical for normal use. However, designers and graphic artists will certainly appreciate the fineness of the image. High resolution will also be a big tax on fps if you want to play in native resolution.
Although the 4K display is not entirely suitable for gamers, it cannot be denied that it is really great. 100% AdobeRGB coverage has been confirmed and more than 100% sRGB is a matter of course. Thanks to the probe, we also know about 94% DCI-P3 and 99% NTSC. Gamma level is 2.3 with a small deviation and the maximum brightness attacks the limit of 400 nits. The uniformity of the display, whether of colors or backlight, is also very good with only small deviations in the right part of the tested piece. We measured great values in color deviation or accuracy. Delta-E has an average value of 0.97 and a maximum of only 2.13. These are really great parameters, because Delta-E under 2 is rated as an ideal value for design work. The measured values are almost the same as on the Duo 15, which only confirms that it is most likely the same display.
The ROG Game Visual application is used to control the display, where you can switch between several modes or adjust the color parameters accordingly.
