This is a snippet taken from the full review of the IdeaPad S940. You can read the entire review here.
Opening the S940, you’ll be greeted by a 14-inch screen. My review unit came with a 4K 3840×2160 HDR display which, I have to say, is absolutely gorgeous.
Like, this is one of the best screens I’ve ever seen on a laptop. Colors are vibrant, it has 500 nits of brightness, and blacks are inky black despite the machine using an LCD. It has curved glass on the left and right sides for an immersive feel, and the slim bezels allow the S940 to take up a smaller overall footprint. If you get a chance to check this screen out before you buy it, go do it. It’ll be worth your time.
Normally, when a phone comes with slim bezels, it uses a notch that cuts into the screen to house the front-facing camera and other sensors. It’s a similar story with the IdeaPad S940, but instead, it opts for a sort of reverse notch where a cutout sits above the screen.
As you can see, Lenovo raises the bezel of the S940 a bit to fit the webcam and necessary Windows Hello sensors. It also works as a grip so you can open the laptop with one hand. I’m a huge fan of this design. Not only is it functional, but it also looks pretty good and makes the laptop unique. There are a couple of other manufacturers doing similar designs, so at some point, this reverse-notch look could become the new norm. But for the time being, it’s a rarity, and I’m in favor of it expanding to more devices over time.
Those sensors I mentioned aren’t just used for Windows Hello. For that, they work really well, but Lenovo also threw in a new feature that aims to make using multiple monitors easier.
Called Glance, the IdeaPad S940 uses the IR sensors to track where your eyes go. If it detects you’re looking at a separate screen to your left or right, it’ll move the content from your main screen to the secondary display. It doesn’t work with a monitor above your main display which is why I didn’t use it very much, but it’s there if you find moving content manually with a mouse is too hard.
In addition, Glance can notify you if someone is looking over your shoulder at your screen and can put your laptop to sleep if you step away from it. These are kind of gimmicky features, but they’re there if you want them.
