For the most reliable connection, connect the laptop to the TCL TV with HDMI, then choose the matching HDMI input on the TV. For wireless use, first identify the TV platform: Google TV supports casting from Chrome and Chromecast-enabled apps, while select TCL Roku TVs support Windows screen mirroring or AirPlay. Those wireless methods do not all mirror the entire laptop screen.

Choose the connection that matches what you want to do

Connecting a laptop can mean displaying the whole desktop, extending the desktop as a second screen, or sending video from a supported app. HDMI can carry the laptop display to the TV. Wireless casting may send only a tab or media, depending on the app and method.

Method Best fit Main dependency Trade-off
HDMI A direct laptop display connection A compatible laptop video output and an available TV HDMI input A cable runs between the devices; an adapter may be needed.
Chrome or app casting Castable browser content or media to TCL Google TV Both devices on the same Wi-Fi network and a supported Cast option Casting content is not necessarily full-desktop mirroring.
Windows screen mirroring A Windows laptop and compatible TCL Roku TV Screen Mirroring enabled on the TV and wireless display support on the laptop Compatibility can vary by TV model and computer.
AirPlay A Mac and a supported TCL Roku TV Compatible model and Roku OS, with AirPlay enabled AirPlay is not available on every TCL TV.

Connect with an HDMI cable

  1. Check the laptop for an HDMI video output and the TCL TV for an available HDMI input. If the laptop has a different port, confirm that it outputs video and choose a compatible adapter.
  2. Connect the cable to the laptop and the TV.
  3. Using the TCL remote, select the HDMI input where the cable is connected.
  4. On the laptop, choose whether to mirror or extend the display if you want to change how the TV is used. The exact display controls depend on the laptop’s operating system.

A USB-C-to-HDMI adapter works only if that USB-C port supports video output through DisplayPort Alternate Mode. Check the laptop specifications or manual before buying an adapter; the shape of a USB-C connector alone does not confirm video support. TCL also describes converting a DisplayPort output to HDMI with an adapter. TCL’s HDMI and wireless connection guide.

Cast from Chrome or an app to TCL Google TV

TCL’s Google TV casting guidance covers the current Chrome browser and Chromecast-enabled apps when the laptop and TV are on the same Wi-Fi network. This is a way to send supported content; it does not establish that the TV accepts Windows’ Miracast “Connect to a wireless display” projection method. TCL Google TV casting support.

Should you buy an adapter or streaming device?

Check the ports and TV platform before buying anything. An adapter is useful only when it matches a laptop port that supports video output. An external Chromecast may be relevant if the existing TV lacks a compatible built-in casting route and you want wireless casting, but it is not a default requirement for TCL Google TV with Chromecast built-in.
