The Problem Explained

Occasional glitches are unavoidable, even on a platform as extensive and dependable as Twitch. Fortunately, Twitch’s support team is usually prompt to provide a solution for any new glitches discovered by the community.

However, some bugs aren’t considered widespread or significant enough to be priorities, so it’s up to the community to find a fix.

One of these bugs is the Twitch fullscreen not working problem.

As you can see in this Reddit thread, it’s easy for users to become frustrated when a simple feature doesn’t work. One user even created a GIF to illustrate the problem better. However, an official solution is nowhere in sight.

Fullscreen mode on any content-streaming website is one of the fundamental features for allowing you to enjoy it properly.

Let’s take a look at some of the proven fixes for this problem.

Fix 1: Use This Simple Workaround Trick

Many Twitch users prefer keeping their extensions active while watching a stream to enhance their viewing experience. Some of these extensions are designed to prevent ads from showing, while others provide a redesigned interface.

BBTV is one of the most popular extensions for Twitch. More than a few million users currently have it installed.

What does this have to do with Twitch not opening streams when clicking on Fullscreen?

According to this Reddit thread, disabling BBTV is guaranteed to solve the problem. However, many users prefer keeping the extension active while on Twitch, so how can they enjoy the best of both worlds?

A user known by the nickname ”taurmice” found a simple workaround. To apply this method, follow the steps below.

  1. Open Twitch and sign in to your account.
  2. Load the stream you want to watch in “default” watching mode.
  3. Instead of clicking the Fullscreen button in the bottom-right corner, click the one next to it, which is for Theater Mode.

  4. Now that your stream is in Theater Mode, double-click with your left mouse button on the viewing window itself. The stream will go into Fullscreen mode.

You should now be able to watch Twitch on Fullscreen without disabling or uninstalling your BBTV extension.

Fix 2: Use A Different Browser To Access Twitch

Even though Chrome is widely utilized by many PC users, it is important not to overlook alternative browsers.

Chrome is a great universal browser, used daily by countless people. However, there are alternative options available for accessing Twitch. You won’t know whether or not they are more suitable until you try them.

You can give OperaGX a try, which is a gaming browser that comes with a Twitch section included. The issue of Twitch fullscreen not working may not be a problem in that browser. It’s worth checking out.

Many alternative browsers are also available. We have a comprehensive guide covering that topic, which you can find here.

Multiple users reported that disabling any extensions used to improve or modify your Twitch experience can help resolve the problem with Twitch failing to enter full screen.

One of the examples for such an extension is BetterTTV, also known as BTTV, which is widely used by members of the Twitch community.

Specifically, this problem was addressed in this particular Reddit thread, and the top comment is a solution suggesting a possible interference between Twitch’s Fullscreen mode and the BTTV extension.

By disabling BTTV, or any other similar Twitch-related browser extension, you may be able to immediately solve the problem with Twitch not entering full-screen mode.

You can always use a different device to watch Twitch for an improved viewing experience if playback isn’t as smooth as you want on your PC.
