The Blade 15's display reached only 275 nits of brightness, which makes it much dimmer than the panels on the Omen 15 (320 nits) and the category average (279 nits).
It's a shame those vibrant colors don't reach their full potential because of the Blade 15's below-average brightness. Colors were also pretty vivid ultraviolet lighting in an indoor garden was a saturated shade of eggplant purple. The panel was sharp enough that I could see every curl in Matthew McConaughey's signature wavy hairstyle in The Gentleman trailer.
The 144Hz refresh rate panel was vivid but not superbright.
