The AVerMedia A850 USB DVBT is a USB tuner for receiving DVB-T digital terrestrial television on a Windows PC. Its driver enables Windows to recognize the tuner and allows compatible TV software to communicate with the hardware. Before downloading, check that the package matches your Windows 11, 10, 8, or 7 installation and its system architecture.

Key Features

• USB tuner recognition: Provides the device-specific support Windows needs to identify the A850 as a TV tuner rather than an unknown USB device.
• TV application access: Lets compatible viewing software use the tuner to scan for available DVB-T channels and receive broadcasts.
• Hardware communication: Supports the exchange of tuning commands and broadcast data between the USB device and your PC.
• Foundation for viewing and recording: Enables supported television applications to access the hardware for live TV and recording, where those features are available.

How to Install

1. Confirm your Windows version. Check whether you are running Windows 11, 10, 8, or 7, and verify whether your installation is 32-bit or 64-bit. Select an AVerMedia A850 USB DVBT driver package that explicitly supports your configuration; older packages may not work on newer Windows releases.

1. Download and extract the package. Save the driver to a convenient folder. If it arrives as a compressed archive, extract its contents before starting installation. Close any TV viewing applications.

1. Install the driver. Follow the included instructions regarding when to connect the tuner. Run the installer if one is provided. For a manual installation, open Device Manager, locate the tuner or unidentified USB device, choose Update driver, and browse to the extracted driver folder.

1. Reconnect and verify the device. Restart Windows if prompted, then connect the tuner directly to an available USB port. Check Device Manager to confirm that it appears without a warning icon. If installation fails, verify package compatibility rather than forcing an unsupported driver.

1. Set up television reception. Connect a suitable antenna, open compatible DVB-T software, select the A850, and run a channel scan for your region. Available channels depend on local DVB-T coverage and antenna reception; installing the driver alone does not provide TV software or guarantee a signal.

Common Issues and Fixes

• Installer fails or rolls back: Run the AVerMedia setup as administrator, close other TV/DVB software, and temporarily pause antivirus. If setup still fails, uninstall any previous AVerMedia A850 package, reboot, then reinstall the driver matching your Windows version/architecture.
• Device not detected: Plug the A850 directly into a rear USB 2.0 port, not a hub. Check Device Manager for an unknown/USB device; unplug/replug after driver install. Try another cable/port and confirm the tuner LED/antenna is connected.
• Version conflicts: Remove old AVerMedia drivers and TV apps in Device Manager/Programs and Features, reboot, and install one A850 driver package only. Avoid mixing generic BDA/DVB-T drivers with AVerMedia software.
