How To Fix Delay/Lag/Slow Response On Chromecast

Chromecast lets you turn your standard TV into a smart TV. While Chromecast allows you to enjoy various streaming apps on your standard TV, it does come with problems. Are you experiencing a delay, lag, or slow response while using Chromecast?

Experiencing delay, lag, or slow response on your Chromecast could be due to Wi-Fi interference. To fix this issue, ensure your Chromecast is in close proximity to the router, reduce other devices’ Wi-Fi usage, or consider using a 5GHz Wi-Fi network if available for faster and more reliable streaming.

Network congestion and interference from other devices can cause delays on your Chromecast. To address this, move your Chromecast closer to the router, limit the number of devices connected to your Wi-Fi network, and use a 5GHz network if possible for smoother streaming.

Outdated firmware on your Chromecast can lead to performance issues. To resolve this, open the Google Home app on your mobile device, select your Chromecast, and check for any available firmware updates. If updates are available, install them to improve performance and reduce lag.

How To Fix Chromecast Slow And Choppy

Holding a remote while pointing in the TV

Is Chromecast running slowly or is the quality choppy? Here are some simple solutions to resolve the issue.

You can fix Chromecast slow and choppy by downloading the content you want to watch. Close any apps that are running in the background. Delete any unused apps to free up memory space for streaming live content. Reduce the number of connected devices on the same network as Chromecast.

Two additional reasons for Chromecast being slow and choppy are bandwidth and video playback quality.


Chromecast uses your device to stream content. Because both Chromecast and the device you are streaming from require an internet connection, the two devices are consuming large amounts of bandwidth.

Bandwidth is much like a highway. The size of the highway determines how many cars can travel on it at one time. If the highway is too small, too many cars on the highway mean cars will be sitting in traffic until space opens up.

The internet bandwidth is the same way. If too many devices are connected to the same network, the network will not have the space to accommodate all of the devices.

Reducing the number of devices that are streaming at the same time will increase network bandwidth.

Adjust Video Quality

Unfortunately, not all movies or television shows can be downloaded. In this case, you need to change the video playback quality.

While this isn’t the favorite option when watching your favorite movie, lowering the quality of the movie will increase bandwidth and will reduce the amount of lag you get from streaming directly from the app.

Step 1: Press the button located on the top-right side of Chrome.

Step 2: Go to ‘Options’.

Step 3: Select a lower resolution such as 720 or 480.

If, after doing what you can to boost the network signal, here are a few more suggestions to try if you are experiencing a lag when casting from a desktop.

Close Out Apps

Because Chromecast and your desktop require an internet connection to stream content, any apps running in the background on your desktop will take away needed bandwidth.

Closeout any apps running in the background. Closing these apps will also increase the memory space needed to stream live content.

Use Hardwired Connection

Using a hardwired internet connection, such as with an Ethernet connection, lets you connect Chromecast directly to your router. This will increase your internet speed between the two devices and will reduce any lag.

A hardwire connection may not be ideal, especially if you are someone who hates seeing cords. But you will get a more stable connection that is stronger and less prone to audio and content delays.
