The ATI Radeon HD 2400 PRO driver helps Windows communicate with this legacy ATI graphics card, enabling appropriate display settings and hardware-accelerated graphics where supported. Before downloading, check the package’s compatibility carefully: Windows 7 and Windows 8 support depends on the driver release, while Windows 10 and Windows 11 do not have official ATI driver support for this GPU.

Key Features

• Display configuration: Provides access to supported resolutions, color settings, and refresh rates beyond what a basic display driver may offer.
• Graphics acceleration: Enables the card’s supported DirectX and OpenGL capabilities for compatible applications and older games, subject to driver and operating system limitations.
• Video playback support: Allows compatible media software to use available hardware-assisted video decoding, potentially reducing processor load.
• Multiple-display controls: Supports configuration of connected screens when available through the card’s outputs and the installed driver’s control panel.

How to Install

1. Confirm your graphics hardware and Windows version. Open Device Manager and check the entry under Display adapters. Verify that the card is an ATI Radeon HD 2400 PRO, then check whether your Windows installation is 32-bit or 64-bit. For a branded desktop, also review the computer manufacturer’s driver guidance.

1. Choose a compatible driver package. Read the supported hardware and operating system details before downloading. Do not assume that a Windows 7 or Windows 8 package will work on Windows 10 or Windows 11. Some systems may need to rely on a driver offered through Windows Update or the Microsoft Basic Display Adapter, with reduced functionality.

1. Prepare the system. Save open work and create a restore point if System Protection is enabled. If replacing a malfunctioning driver, keep a copy of the previous working package so you can recover if necessary.

1. Run the installer. Extract the download if required, launch the setup program, and follow its instructions. If the installer reports unsupported hardware or an incompatible operating system, stop rather than forcing installation.

1. Restart and verify operation. After rebooting, check Device Manager for warnings and open Windows display settings to select a suitable resolution. Test normal desktop use and video playback; if problems appear, use the driver rollback option where available.

Common Issues and Fixes

• Installer fails or stops early: The HD 2400 PRO is legacy, so modern Windows may reject the old Catalyst package. Run setup as Administrator, use compatibility mode for the driver’s target OS, and temporarily disable driver signature enforcement if required.
• Device not detected: Check Device Manager for unknown/display adapter entries. Reseat the card, confirm the monitor is connected to the HD 2400 PRO output—not the motherboard—and try another PCIe slot if available.
• Version conflicts/Code 43: Remove existing AMD/OEM drivers with DDU in Safe Mode, reboot, then install the correct 32/64-bit legacy Catalyst package. Block Windows Update from replacing it with a generic driver.
