Our top pick exemplifies some of these qualities—the excellent AXR85 from Cambridge Audio delivers killer sound, and has a ton of different ways to pipe music through it from other devices (as well as all the requisite ways to output said music on the other end). It’s a genuinely attractive, sleek-looking example of modern design, as well, all brushed grey aluminum and minimalism. It’s one of the very best two-channel stereo receivers available right now, and pairs well with the best speakers from our roundup....

In addition to a USB port for charging a smartphone, our reviewer discovered this lamp also has capacitive sensors that are directly incorporated into the base of it, so it’s touch-friendly. The total brightness of the lamp results in a color rendering index of 93 CRI (color rendering index), which is just below the 100 CRI product by natural sunlight. The CRI itself helps determine the lamp’s ability to accurately display any desk-based objects full color underneath the lamplight....

If you want something more robust than surge protection, you should also take a look at our full list of the best uninterruptible power supplies (UPS). For everyone else, read on to see our overview of the best surge protectors. A PowerChute system also keeps you informed on what equipment is using how much voltage. If you prefer to shift some of the voltage elsewhere, you can do just that....

Facebook profiles, pages, and groups are all features that allow people to stay connected with everything that matters in their lives, including friends, businesses, celebrities, and interests. Despite this, they do have their differences. What Is a Facebook Profile? Think of a Facebook profile as your personal page as an individual. You actually can’t use any other Facebook feature without signing up for a profile first. Your profile is a place where you can put information about yourself (your name, profile photo, short bio, where you went to school, where you work, what your favorite books are, and so on)....

It used to be that a laptop was a little flip-top box of sacrifices. It ran hotter, the chips were clocked slower to mitigate that heat and use less battery power, and the hard drives were much slower. But now, with Apple’s mobile-first Apple Silicon systems, portable Macs are every bit as good as desktop Macs. For most people, there’s no longer any reason to buy an iMac, a Mac mini, or even a PC—unless you prefer Windows or play games....

The first question to ask is how much you want to spend on an iPad. In general, the more you spend, the larger the storage, screen size, and computing power. 12.9-inch iPad Pro Apple introduced an iPad with a huge 12.9-inch display to bridge the gap between tablets and laptops. The iPad Pro is definitely a tablet with the processing power of a PC. The A12Z chip is about as powerful as a mid-range laptop, and with 4 GB of RAM for apps to go along with that expansive display, it’s a multitasking beast....

The Studio Display has two options for its screen—regular and low-reflectivity nano-texture glass. You can also choose a stand. The standard stand offers tilt adjustment and nothing else. The height adjustable stand adds a few pounds to the weight and a few optional inches to the height. And then there’s the VESA mount, which lets you mount the display onto any third-party stand. The problem? It covers up the Apple logo, and not even all of it....

While it lacks some of the latest self-defense techniques of its competitors, Ultimate Antivirus makes up for it with an array of add-ons. The good news is that, together, they make for good protection. The bad news is that the best of them cost extra, making the security program expensive. We went ahead and tested TotalAV’s antivirus software to see how it stacks up against the other services on the market....

Diagnosing the Problem If your battery isn’t charging correctly, it could indicate a problem with the charger. Still, it’s more likely that the battery needs troubleshooting. If the problem lies with the charger, you might smell an odor of burning plastic when the unit is plugged in, or you may see a physical problem with the unit. The first time you use the charger, it may have an odd smell, but the odor should dissipate quickly and not repeat in the future....

Restoring From Backup Is Best Before we go any further, a note: if you’ve got a backup of your hard drive, it’s better to try to restore from that since it’s more comprehensive and will contain more than just iTunes. If you do have a backup, congratulations on being conscientious and planning ahead. Give yourself a high five and proceed to restore your data from backup. If you didn’t have a backup, research backup software and service options and start using one as soon as you get everything back up and running....

Virtual reality—like any new tech idea—has seen quite a few renditions over the years. From the early consumer versions like the Nintendo Virtual Boy to the more advanced head-mounted displays of the last decade, virtual reality has advanced quite a bit. For some, though, it has never hit the “mainstream” of consumer tech, instead falling into one of the many niche areas of the gaming and entertainment world. Other experts in the field feel that it’s already here....

The pre-loaded YouTube app, which had been on the home screen of iOS devices since the very first iPhone, was gone! Apple removed the old YouTube app in iOS 6 and the way that many people had watched YouTube videos on their iOS devices was totally gone. The app might be gone, but you can still use YouTube on iOS 6. Here’s what you need to know. What Happened to the Old iPhone YouTube App?...

UHD can also be used to describe 8K UHD, which relates to the higher-still 8K resolution. What Resolution Is 4K UHD? 4K UHD resolution is 3,840 x 2,160, as defined by almost all commercial TVs. However, 4K resolution in other mediums can be slightly different, relating to any display that has a horizontal resolution around 4,000 pixels. In the case of some PC monitors, they can have a resolution of 3,840 × 1,600, or 3,840 x 1,080, although those aren’t typically referred to with the moniker of 4K UHD....

The file extension helps an operating system, like Windows or macOS, determine which program on your computer the file is associated with. For example, the file notes.docx ends in docx, a file extension that’s associated with Microsoft Word on your computer. When you attempt to open this file, Windows sees that the file ends in a DOCX extension, which it already knows should be opened by Word. File extensions also often indicate the file type, or file format, of the file, but not always....

What Are Lock Screens Used For? The lock screen has been around for almost as long as the computer, but in these times where mobile devices are so intertwined in our daily lives, the ability to lock our devices has never been more important. But a device doesn’t need a password for a lock screen to be helpful. One very important facet of a lock screen on our smartphones is to keep us from accidentally sending it commands when it is still in our pocket....

What Is an ASHX File? A file with the ASHX file extension is an ASP.NET Web Handler file that often holds references to other web pages used in an ASP.NET web server application. The functions in the file are written in the C# programming language, and sometimes the references are so short that the file may end up just being a single line of code. Most people encounter this format only by accident when they try to download a file from a website, like a PDF file....

Why Would You Use An Email Alias? Email aliases are helpful when you need to create a short, simple, and generic address for some specific purpose. For instance, let’s say that Fred Johnson works in human resources at his company and is responsible for interviewing potential candidates for current job openings. He might want to post job ads on certain job board websites, but he’d rather not use his professional fredjohnson@companyname....

What is Byte? Byte is a short-form video app from the creator of Vine that’s available for Android and iOS. The premise is simple: Users create 6-second looping video clips and share them with their followers. You can upload a video you’ve already shot to the app or create clips using the built-in camera. Likewise, you can also download videos you like and share then on other social media platforms like Instagram, Facebook, and Twitter....

What is Google Fi? Google Fi originally launched as Project Fi on an invitation-only basis in 2015, and it opened to the public in 2016. When it launched, it was only compatible with the Nexus 6, and the public launch added the Nexus 5x and the Pixel line. Compatibility has since been extended to most Android devices in addition to iPhone, although Google only offers personalized customer support and trouble shooting for a fairly short list of devices....
