The AVerMedia H788 PCIe Hybrid Analog ATSC is an internal TV tuner card designed for analog and ATSC digital television reception. Its driver allows Windows to recognize the hardware and makes the tuner available to compatible TV-viewing and recording software. When choosing a download for Windows 11, 10, 8, or 7, check that the package explicitly supports your operating system and the H788 model.

Key Features

• Hardware recognition: Helps Windows identify the PCIe tuner and communicate with its components.
• Analog and ATSC tuner access: Enables compatible applications to use the card’s supported television reception modes, depending on the available signal and connections.
• Viewing and recording support: Provides the hardware interface used by suitable TV software for channel tuning and capture. Recording features depend on the application you install.
• Device management: Allows you to check the tuner’s driver status in Device Manager and address issues caused by a missing or mismatched driver.

How to Install

1. Confirm the hardware and Windows version. Verify that your card is the AVerMedia H788 PCIe Hybrid Analog ATSC. Check your Windows edition and whether the system is 32-bit or 64-bit before selecting a driver.

1. Choose a compatible package. Download an AverMedia driver that lists this model and your Windows version. Do not assume a package intended for Windows 7 or 8 will also work on Windows 10 or 11.

1. Prepare the computer. Close any TV-viewing or capture applications. If the card is not installed, shut down and disconnect power before fitting it into a compatible PCIe slot, following the hardware instructions.

1. Install the driver. Extract the download if necessary, then run the included installer and follow its prompts. If no installer is provided, open Device Manager, locate the tuner or unidentified device, select Update driver, and browse to the extracted driver folder.

1. Restart and test reception. Restart if prompted, then check Device Manager for warning icons. Open compatible TV software, select the H788 tuner, connect the appropriate signal source, and scan for channels.

If Windows blocks the driver or the tuner remains unavailable, verify package compatibility rather than disabling driver-signature protections. Channel availability also depends on your antenna or signal source, local broadcasts, and application settings.

Common Issues and Fixes

• Installer fails or rolls back: The H788 package is old and may need Windows compatibility mode and administrator rights. Extract the download, run `Setup.exe` as administrator, reboot before retrying; if blocked by driver signing, use a signed build for your Windows version.
• Device not detected: Power off, reseat the PCIe card, confirm the slot and BIOS enumerate it, and check Device Manager for an unknown multimedia device. Install motherboard chipset drivers and try another PCIe slot.
• Driver/software version conflicts: Uninstall older AVerMedia tuner drivers and TV apps first, remove hidden devices in Device Manager, reboot, then install the H788 package. Avoid mixing drivers from other AVerMedia models.
