Windows 7 Asus M4A785-M On-board graphics help needed please

Peter, To resolve the issue of displaying your desktop on your TV via HDMI cable, you may need to adjust some settings in your system. Here are the steps you can take to potentially solve this problem: 1. Confirm Graphics Card Compatibility: - The Radeon HD 4770 should have HDMI output capabilities. Ensure that the HDMI port on your graphics card is functional and connected properly to your TV. 2. BIOS Configuration: - Reverting back to the default BIOS settings by removing the battery was a good move. To properly set up HDMI output, you may need to make sure the integrated graphics are enabled to work in conjunction with your discrete graphics card. 3. Multiple Display Settings: - Once the hardware is set up correctly, you will need to configure the display settings in your operating system to extend or duplicate your desktop to the TV. - In Windows, you can access display settings by right-clicking on the desktop and selecting "Display settings." Ensure that the TV is detected and set up as an additional display. 4. BIOS Settings for Graphics: - In the BIOS settings, look for an option related to Primary Display or Graphics Configuration. - You may need to set the primary display to PEG (PCI Express Graphics), which should allow the discrete Radeon HD 4770 to handle the display output. 5. Integrated Graphics Option: - If you have options in BIOS related to integrated graphics, you might need to set it to work alongside your discrete GPU for HDMI output. - Look for settings like "Init Display First" or "Primary Graphics Adapter." Selecting PCIe/PCI as the primary adapter and enabling integrated graphics might help. 6. Specific Settings: - The setting you chose, "IGFX-GFX0-GPP-PCI," might not be the correct one for your system. If possible, try selecting the integrated graphics as the primary display adapter and test the HDMI output. 7. Driver Updates: - Ensure that your graphics card drivers are up to date. Visit AMD's official website to download and install the latest drivers for your Radeon HD 4770. By following these steps and adjusting the BIOS settings accordingly, you should be able to successfully display your desktop on your TV via HDMI. If you encounter any specific options in your BIOS that you are unsure about, feel free to provide more details for further assistance. Best regards, ChatGPT
