There was a time when TVs were built to last, and they often did. In fact, it wasn’t unusual for families to keep their main TV for decades before having to buy a new one. In the modern age of cheap TVs, some people prefer to trade up more frequently, but if you’re holding on to a low-resolution TV and want to buy an Amazon Fire Stick, you should go with the standard HD version.

The reason for that is because if you use a higher resolution stick, your viewing experience won’t be upgraded. A 4K Fire Stick will work, even if your TV doesn’t support 4K resolution. As long as you have an open HDMI port and an internet connection, you’re all set. You can download apps, watch your favorite shows, and even listen to music. You’ll have full access, but you will not have 4K resolution. That’s because when you plug a 4K Fire Stick in, it automatically delivers the picture and sound to the resolution your TV supports.

Not only will your resolution remain the same, you’ll also be paying more money. The HD Fire TV Stick currently retails for $34.99 on Amazon, while the 4K Select version is $39.99. The 4K Plus and 4K Max regularly retail for $49.99 and $59.99 respectively. So, your best bet is to go with the HD stick, as it will give you the streaming experience you want, and save you some money in the process.

One of the Fire TV Stick’s best features is that setup is really easy. Just plug it in to the TV’s HDMI port, connect it to power, enter your Wi-Fi credentials, and log into your Amazon account. So, while you’re not getting a resolution upgrade by using a Fire Stick on an outdated TV, you’re definitely stepping up in terms of overall capabilities. Plus, the stick is plug-and-play; all you need to do it plug it is, and all the functionality is ready to go.

However, older TVs could struggle with a Fire Stick because of an incompatibility issue. It involves the built-in High-bandwidth Digital Content Protection (HDCP), which is in place to prevent unauthorized digital copying. This incompatibility can cause issues with playback but can often be resolved with a software update.

Then there’s the HDMI port you use. On newer TVs, using the wrong HDMI port can degrade performance, but it’s less nuanced on an older device. On older TVs, you can usually use any HDMI port, but you’ll have to be sure you choose the right input on your settings.

Other problems you might encounter include internet connectivity issues, faulty power cables, or even overheating issues. None of those necessarily stem from having an older TV though. You can get more troubleshooting information in your Fire TV Stick’s settings, or on Amazon’s website.
