Roku TV Flickering

It’s impossible to watch shows and movies when your Roku TV flickers as it makes your eyes tired and because the content no longer feels immersive. Why is this problem happening on your device? Can you resolve this issue so you can watch something without straining your eyes?

Roku TV Flickering

Roku TVs flicker if the display auto-adjust refresh rate is on, the resolution doesn’t match the TV’s resolution, or there are bugs in the app or operating system (OS). Disabling the auto-adjust refresh rate, using supported resolutions, and power cycling the TV can fix flickering issues. 

This guide explains why your Roku TV flickers when you use your device. It also contains several solutions to resolve this issue. 

Why Is My Roku TV Flickering?

Roku TV Why Flickering

If you’ve never seen your Roku TV flicker before, it can be concerning when it starts happening to your device. Luckily, there are six methods you can try to fix this issue, depending on what’s causing trouble on your TV. Here’s why you’re facing this problem, along with different solutions to resolve them.

Auto-Adjust Display Refresh Rate Is On

Auto-adjust display refresh rate is a feature available on most Roku TVs. Generally, your device will play all content at 60 fps (frames per second). Animation and motion look smooth when you watch movies, shows, or sports at this frame rate.

However, as this isn’t the refresh rate that the content was initially shot at, you may have a different experience than what the director intended. Enter auto-adjust display refresh rate, which changes the refresh rate from 60 fps to the content’s native refresh rate.

For instance, most movies in the U.S are shot at 24 fps. Depending on where the content is created, the native refresh rate can be 25 fps, 30 fps, 50 fps, and 60 fps.

When the auto-adjust display refresh rate is enabled, your Roku TV will change the fps of the content. However, this can introduce flickering.

Wrong Resolution on Your TV

Sometimes, it can flicker if you run the wrong resolution on your Roku TV. Fortunately, if this is true for you, it is easy to fix.

Broken Apps or Operating System (OS)

If you’re experiencing flickering only in certain apps or while on the home screen, it’s likely that an app or the operating system (OS) is causing this issue. 

Modern smart TVs and accessories come with modern problems, including software bugs. For instance, video streaming apps like Prime Video sometimes stop working on smart TV accessories like the Fire TV Stick, and you can learn more about that in this article
