Laptop Ultraportable with HD, QHD, 4K and TouchScreen

Today's laptops are generally offered Ultra HD as popular resolution of choice for the highest-end ultraportables. As 4K screens have four times the resolution of a full HD display, you can fit a lot onto them. The sheer number of pixels requires more power, however, and 4K-equipped systems usually see a significant drop in battery life compared with similar full HD systems.

Moreover, there's also the question of content. Although 4K TVs and displays are becoming increasingly common, there still aren't a lot of places to stream 4K video (this is slowly improving on some streaming services), and gaming in 4K is definitely way more than any ultraportable can support. At present, these displays are best suited to uses like photo and video editing, but they do look stunning.

Furthermore, some premium laptops now use QHD or QHD+ screens, which are resolutions that fall between HD and 4K. They represent a nice middle ground between expensive, power-draining 4K resolutions and sharp, better-than-HD picture quality, so you should be happy to see QHD or QHD+ on a laptop you're considering buying.

The other feature to watch for is support for touch input. While touch-capable displays were uncommon just a few years ago, they're now much more a thing in ultraportables, even in the entry-level and business-laptop categories. Windows 10 includes some baked-in gesture controls and touch-friendly features, which helps promote its use.

Also, touch technology is also useful on a bus or train where you may not have a mouse, making it a good match for ultraportables. Even if you don't regularly use touch in your day-to-day computing and don't plan to incorporate it, it may be worth having just so you don't regret the decision not to get it down the road.
