Asus vivobook x540sa 15.6
The Acer Aspire 5 and HP 15 Laptop are brighter, measuring at 258 nits and 222 nits, respectively, though even those models are below the industry average of 268 nits. It's also not very bright, with the VivoBook 15 maxing out at 205 nits in lab tests.

I found the laptop hard to use with the Windows 10 night mode because of this sheen issue. The issue affects dark colors, specifically black and grays, and if you rely on dark mode within most apps, it's hard to ignore. You have to look at the laptop at an exact angle - about 100 degrees - to see the display without a sheen. The viewing angles of the VivoBook 15 are a bit odd, too. And while I was able to edit RAW photos in Adobe Lightroom, I felt more confident about the result only after connecting to an external monitor with better color reproduction. I can get through a YouTube video without immediately recognizing it, but it becomes apparent once I switch displays.
Anecdotally, the display on the VivoBook 15 is obviously off-kilter. While that's ahead of similarly-priced laptops, including the Acer Aspire 5, which scored 63 percent, and the HP 15, which scored 67 percent, it's behind the industry average of 85 percent. In lab tests, the VivoBook 15 scored a measly 65 percent on the sRGB color gamut. It made episodes of vintage TV shows like Baywatch, already with a worn-in color palette, look older than they are, while movies like the recent remake of Emma were extremely hard to see in dark scenes. But beyond its widescreen look, the display's dim color profile and weird viewing angles make it an underwhelming device for consuming online video. The VivoBook 15's 15.6-inch, 1920 x 1080 NanoEdge display offers little bezel on either side of the laptop, with a bit more at the top to accommodate the webcam. There's also a MicroSD slot, which is a nice-to-have and allows adding on storage space, but I would have preferred a standard SD slot to work with my DSLR on the go.
