Smart TVs looked like the obvious move when they launched. One less box under the TV, everything built in, nothing extra to buy. A few years later, many people are watching their menus get slower every month, waiting for apps to load, and realizing their TV hasn't seen a meaningful update in years and no longer feels new. A $20 Fire TV Stick doesn't fix the screen, but it quietly fixes almost everything else.

One of the strongest arguments for buying physical media in a digital world is the unwritten rule that "the disc is always the true version." It's long been the case that buying DVDs or Blu-rays allows access to original edits or missing episodes that aren't available on any streaming service. However, for one of my favorite shows, streaming has now become the version that's more faithful to the original.

HDMI-CEC was supposed to make home theater setups a lot easier to work with. At first, it seems like the kind of feature that would just work, but then the problems arise. The annoying part is that the protocol isn't broken exactly. It just has issues when it comes to handling the way most people actually build their setups. So it's better to turn it off.

Blu-ray may very well be the last physical media we get when it comes to video content, but if history had gone just a little differently, it would be HD-DVDs being frantically collected by media nerds today, and not Sony's gift to image quality purists.

Buying a high-end monitor and then plugging it in with whatever cable came in the box is something most people do without thinking twice. HDMI is everywhere; the port fits, and the picture shows up, so everything seems fine. The problem is that there are plenty of issues that no one talks about. The cable and port you're using matter more than most people realize, and HDMI specifically has some limitations that aren't obvious from the outside.

Smart features on a TV can be very useful. You can stream content using apps such as Netflix or control your TV remotely with your smart home. You need to connect your TV to the internet to use some of these features, and doing so can expose a lot of your data.

Most people treat Bluetooth earbuds as a passive accessory, something that sits in your ears and plays audio. The security conversation around them, when it happens at all, tends to focus on whether someone can intercept your music or track your location. Many devices can be hacked, and your Bluetooth earbuds are no exception.

If you look at the back of your TV, there are many ports that you probably never use. Some older TVs include an RS-232 serial port similar to those that you'd find on the back of old PCs. While the main uses of this port include professional diagnostics and servicing, there are several ways you can use your TV's serial port for other things.
