What To Know

  • Chromecast can be successfully connected to computer monitors for visual display.
  • For monitors without built-in speakers, Chromecast with Google TV can be paired with external Bluetooth speakers to provide sound output.

In this article, I’ll clearly show that Chromecast is fully compatible with computer monitors. 

I’ll guide you through connecting Chromecast to a monitor and explain how to get sound output when your monitor lacks built-in speakers. 

Additionally, I’ve explored a solution using an HDMI capture card with a laptop and Chromecast, which I will also demonstrate. 

Let’s dive in!

Try Bluetooth Audio for Chromecast-Monitor Setup

Chromecast with Google TV features a built-in Bluetooth capability, allowing you to connect the Chromecast to any external Bluetooth speaker. 

This setup is particularly useful when using Chromecast with a PC monitor that lacks built-in speakers. 

In my testing, I connected a Chromecast with Google TV to an LG 27UP600-W monitor, which doesn’t feature built-in speakers. 

Here’s how to set it up:

Step 1: Plug the Chromecast into the HDMI input port of your monitor

Step 2: On your monitor, switch the input source to HDMI.

Step 3: Once the Chromecast is on, set up the sound output. Go to Settings β†’ Bluetooth β†’ Pair remote or accessories.

Bonus: Using an HDMI Audio Splitter with Monitors Lacking Built-in Speakers

Not all computer monitors come with built-in speakers, and using Chromecast with such monitors can result in videos playing without sound.

To resolve this, we recommend using an HDMI audio extractor.

This HDMI audio extractor enables you to route audio to an external audio system, such as speakers or a soundbar, without affecting the HDMI video quality.

The setup is straightforward: plug your Chromecast into the audio extractor, then connect the extractor to your monitor using another HDMI cable. 

The audio extractor is equipped with ports that let you transmit audio to external audio equipment.

How to Connect Chromecast to Monitor/TV without HDMI

Connecting a Chromecast to a monitor without an HDMI port, like my old Samsung monitor, is straightforward. 

The key is to find the right adapter that is compatible with your monitor or TV’s existing port. Below, I’ll provide a list of adapters for this purpose. 

In my situation, as the old Samsung monitor utilizes a VGA cable, an HDMI to VGA adapter was necessary to establish the connection. 

Here’s what you’ll need to prepare before starting the setup process:

  • Use an HDMI splitter in this setup, as the splitter provides the necessary HDMI ports. Since both the Chromecast and the adapter are designed with HDMI connectors, the splitter acts as an HDMI port, allowing both devices to connect to my Samsung monitor.
  • A VGA cable
  • An HDMI to VGA adapter

Now, let me guide you through the setup steps:

Step 1: Connect the Chromecast to the HDMI input port on the HDMI splitter.

Step 2: Connect the HDMI cable provided with the HDMI-to-VGA adapter to the HDMI output on the HDMI splitter.

Step 3: Connect one end of the VGA cable to the VGA port on the HDMI-to-VGA adapter. Ensure the other end of the VGA cable is plugged into the monitor’s VGA port.

How to Connect Chromecast to a Laptop or PC

Many users aren’t aware that it’s possible to connect Chromecast to a computer or laptop, even if the PC only has an HDMI output. 

The trick is to use the USB port, converting it into an HDMI input port with the help of an HDMI capture card. 

Let me show you how:

My Experience using Chromecast with PC Monitor

The Chromecast with Google TV is used on a ViewSonic monitor

You can easily use Chromecast by plugging the device into any monitor, and it typically works excellently without any issues. 

The main challenge, however, is figuring out how to output sound from the monitor. 

To give you a clearer understanding, I have personally tested the Chromecast with Google TV on various monitors to try it out for you. 

This includes experimenting with monitors that have built-in speakers and those without.

Monitor with Built-in Speakers

I have tested the Chromecast with my Viewsonic monitor with the built-in speakers. 

While the speakers from the monitor work well.

However, I felt that the sound quality didn’t quite meet my expectations for enjoying movies on Netflix or Disney+. 

To improve this, I connected the Chromecast to external Bluetooth speakers and earphones, which significantly enhanced the audio experience. 

This approach proved effective not just for the Viewsonic monitor but also for monitors without built-in speakers. 

Read on for more detailed insights in the next section.

Monitor without Built-in Speakers

Using a Chromecast with monitors that lack built-in speakers presents a challenge, as you’d have no audio for your movies. 

The best way to get sound output from the Chromecast when using a monitor without built-in speakers is to pair it with a Bluetooth speaker, soundbar, or earphones.
