Roku Ultra is one of the most popular streaming devices because it’s affordable and has all the streaming channels you need for your favorite shows and movies. Along with the power cord, you also need an HDMI cable for your Roku Ultra to work. 

Any HDMI cable can be used with Roku Ultra, but not all cables will offer 4K resolution and high speed. To make the most out of the Roku Ultra features, get an ultra-high-speed HDMI cable that supports HDCP 2.2. 

You might be confused about what an ultra-high-speed cable is, or you might be wondering where to buy one. Don’t worry we will cover the details in this article. We will also go more in-depth as to why these are the best cables to use. 

Can I Use a Different HDMI Cable for Roku? 

When you buy a Roku Ultra, it comes with an HDMI cable. You might be looking for a new one though if the included HDMI cable breaks or you need one that is longer. 

All HDMI cables will work for the Roku Ultra, but they might not be able to display content in 4K resolution. To make sure you don’t get stuck viewing everything in a lower resolution like 720p or 1080p, you need to make sure you get an HDMI 2.0 cord that supports HDCP 2.2. 

What is HDCP 2.2? 

HDCP technology has been around for a long time. It’s used by the TV industry to protect content from being copied and distributed illegally. 

All TVs and streaming devices use some version of HDCP. HDCP 2.2 was specifically designed for 4K Ultra content and other devices that stream in 4K or HDR. 

If your HDMI cable does not support HDCP 2.2, you will get an error page on the TV when you try to stream something in HDR or 4K. If the show or movie you want to watch is only available in 4K, you will not be able to stream it. 

What if My HDMI Cable Does Not Support HDCP 2.2? 

Movies and shows that are only made in HDR and 4K like some of the newest ones will not be able to play. Content that is HD can still be viewed as normal though. 

The Roku player will automatically be able to tell that your HDMI does not support 4K and will play in 720p or 1080p instead.
