Most of this Labs test has been dedicated to 4K screens with the same 16:9 widescreen aspect ratio as 1080p displays, but there’s an alternative option, in the form of 21:9 ultra-wide curved displays, such as the 34-inch Philips BDM3490UC. With a resolution of 3,440 x 1,440, the overall pixel count is much lower than that of a 4K panel. It’s precisely 880 pixels wider than a 2,560 x 1,440 screen, with 440 pixels added to each side. The Philips is also curved at the edges, bringing the sides slightly more in line with your peripheral vision.

Dell’s 27in Dell UP2715K offers a compelling alternative to the 4K displays on test this month, with a higher resolution and even smaller pixels. The standard 4K resolution of 3,840 x 2,160 is exactly four times 1,920 x 1,080, and if you similarly multiply 2,560 x 1,440, you end up with the Dell’s 5,120 x 2,880, or 5K, resolution.
There’s a small problem though. Driving this number of pixels at 60Hz requires more bandwidth than a single DisplayPort 1.2 cable can handle, so you need to connect two cables to the UP2715K from your graphics card. The DisplayPort 1.3 standard will overcome this limitation, but no graphics card supports it yet. You can also use the Dell UP2715K as a 4K display with a single cable connected to the mini-DisplayPort input.
Although the Internet has brought huge changes in our everyday lives, there’s arguably no area where it’s had more impact than business and communication. As a tool for keeping people in touch, only the phone can approach its success, and even that pales in comparison to the Internet, which enables free phone, text, and even video calls. All you need is a PC and an Internet connection. Business has boomed online in many ways, and there’s simply no imagining a world without the Internet powering commerce and corporation any more.
Browsing the web is a big part of our daily routines these days. If you’re anything like me, it probably dominates your work life and your personal time. The internet is a trusty tool for all of us, but there are ways to make it even more effective.
These come in the shape of browser extensions – freebie plug-ins that add extra features to your browser, such as blocking movie spoilers, sorting out your spelling and managing your manifold open tabs. Life can be so much easier if you install a few of these…
The Raspberry Pi is an excellent hardware hacking computer. Take your Pi, connect a solder-free breadboard to the General Purpose Input/Output (GPIO) port, plug in a few electronic components, and a whole new world opens up.
The possibilities offered by hardware hacking are difficult to resist. However, not everyone has the inclination or time to construct electronic circuits from scratch. And this is why Raspberry Pi addon boards have become so popular.
