Old Chromecast: 7 Things It Can Still Do
Yes, an old Chromecast can still do plenty of things beyond streaming. Even a first-generation model that no longer receives software updates can still cast video from supported apps, mirror your phone or laptop screen, display photos, and act as a basic digital signage player. The key is knowing which features remain functional and which have been dropped over time.
What Counts as an “Old” Chromecast
Google released the first Chromecast in 2013, followed by the second generation in 2015, the Ultra in 2016, and the third generation in 2018. The older models share a common limitation: they use the original Cast protocol, which relies on a phone, tablet, or computer to initiate playback. Unlike newer Chromecast with Google TV models, they have no remote and no on-screen interface of their own. That distinction matters because Google has gradually moved some features to the newer platform, but the core casting ability remains intact on all generations.
Core Casting Still Works
The most obvious function—streaming from apps—still works on old Chromecasts. As long as the app on your phone or computer supports the Cast protocol, you can send video, audio, or images to the TV. This includes YouTube, Netflix, Spotify, and most major streaming services. The process is identical to a new device: tap the Cast icon, select your Chromecast, and playback starts.
What has changed is the backend. Google has updated the Cast protocol over the years, but the old devices still receive the necessary firmware updates to keep them compatible with current apps. The first-generation model, however, stopped receiving major updates in 2016, so some newer apps may no longer list it as a cast target. In practice, most mainstream apps still work, but you may encounter occasional compatibility warnings.
Screen Mirroring from Phones and Computers
If you want to show a presentation, a photo album, or a mobile game on the TV, screen mirroring is a reliable fallback. On Android, the built-in Cast screen feature sends whatever is displayed on your phone to the Chromecast. On Windows and macOS, the Chrome browser can cast an entire tab or the desktop. This works on all Chromecast generations, including the first.
One limitation: screen mirroring on old Chromecasts can be laggy, especially with fast-moving content. It is fine for static slides or browsing, but not ideal for gaming or video playback. Also, iOS devices do not support native screen mirroring to older Chromecasts; you would need a third-party app, and even then, the experience is inconsistent.
Photo and Art Display
An old Chromecast can turn a TV into a digital photo frame. The Google Home app lets you choose a photo album from Google Photos, and the Chromecast will cycle through those images when idle. This is a great way to repurpose a spare TV or monitor. The feature works on all generations, though the first generation may have a slower transition time between photos.
You can also cast individual photos from your phone to the TV using the Google Photos app. This is useful for showing a single image to a group without everyone crowding around a small screen.
Basic Digital Signage and Kiosk Mode
Because the Chromecast can display a web page indefinitely, it works as a cheap digital signage player. Several free and paid services (like ViewSonic’s Cast or Mvix) let you create a playlist of web pages, images, or videos and push them to a Chromecast. This is often used in cafes, waiting rooms, or small retail shops to show menus, announcements, or promotions.
The limitation is that old Chromecasts only display one source at a time. You cannot split the screen or have multiple zones like you can with dedicated signage hardware. But for a single screen with rotating content, it is a cost-effective solution.
Audio Casting to a Speaker System
If you have a Chromecast plugged into a TV or an audio receiver, you can cast music to it. The TV or receiver must be on, and the volume is controlled by the TV, not by the Chromecast. This works with Spotify, YouTube Music, and most other audio apps. Some users also use an HDMI audio extractor to connect the Chromecast directly to a stereo system without a TV.
This is not the same as a Chromecast Audio, which was a separate device designed for speakers. The standard Chromecast outputs video and audio over HDMI, so you need a screen or a receiver with an HDMI input. If you have an old AV receiver without HDMI, you would need a converter, which adds cost and complexity.
Common Limitations and Workarounds
Old Chromecasts do have some notable drawbacks. They do not support 4K or HDR (except the Ultra), so they are limited to 1080p. They also require a 2.4GHz Wi-Fi connection, which can be slower and more congested than 5GHz. If your router broadcasts both bands under the same name, the Chromecast may connect to the weaker 2.4GHz signal.
Another issue is that Google has stopped providing security updates for the first-generation model. This means it may be more vulnerable to exploits, though the risk is low for a device that only receives casting commands from your local network. If you are concerned, you can put the Chromecast on a separate guest network or just unplug it when not in use.
If an app no longer shows your old Chromecast, try restarting both the Chromecast and your phone. Also, ensure that both devices are on the same Wi-Fi network. Sometimes a router update can change network isolation settings, which blocks casting.
Frequently Asked Questions
Can I still use Netflix on a first-generation Chromecast?
Yes, as of early 2025, Netflix still supports casting to the first-generation Chromecast. However, if Netflix ever drops support for older Cast devices, you would lose that functionality. The app will typically show a warning if your device is no longer compatible.
How do I reset an old Chromecast?
Hold down the button on the device itself for about 25 seconds, until the LED blinks and the device restarts. Then set it up again using the Google Home app. This is useful if the device becomes unresponsive or if you want to change it to a different Wi-Fi network.
Is it worth buying a used old Chromecast?
If you can get one for a few dollars, it is a cheap way to add casting to a TV that lacks smart features. But be aware that the first-generation model is no longer updated, and some apps may stop working eventually. For a little more money, a third-generation model is a better bet because it still receives updates.
Can I use an old Chromecast without Wi-Fi?
No, the Chromecast requires a Wi-Fi connection to receive casting commands. There is no Ethernet port on the standard models, though the Ultra has one. If you have no Wi-Fi, you cannot use the device.
Does an old Chromecast support AirPlay?
No, Apple’s AirPlay is not supported on any Chromecast. You can use third-party apps like Replica or AirScreen to receive AirPlay streams on a Chromecast, but these are not official and may not work reliably.
Can I play local video files from my computer?
Yes, you can cast local files using the Chrome browser. Open the file in Chrome and then cast the tab. However, the video may stutter if the file is large or if your computer is slow. A better option is to use a media server like Plex or Jellyfin, which can transcode the video to a compatible format for the Chromecast.
