1. HDMI-to-DVI Adapter:
Since your graphics card does not have an HDMI port, you'll need an adapter that converts HDMI signals to DVI signals. Purchase a good-quality HDMI-to-DVI adapter that supports your graphics card's specific DVI port type (either DVI-I or DVI-D).
2. DVI Cable:
You will also need a DVI cable that fits your graphics card's DVI port and the adapter's DVI port. Make sure the DVI cable is of the correct length to reach from your PC's graphics card to the TV.
3. Connecting Adapter and Cable:
Connect one end of the HDMI cable to the HDMI port of your TV and the other end to the HDMI-to-DVI adapter. Then, connect the DVI cable to the adapter's DVI port and the DVI port on your graphics card.
4. Adjust Display Settings:
Once you've made the physical connections, you'll need to adjust your display settings to output the video to the TV.
a. Windows: Right-click on the desktop, select Display settings > Advanced display settings. In the Multiple displays section, select the Extend these displays option and rearrange the displays accordingly. Set your TV as the primary display if desired.
b. macOS: Go to System Preferences > Displays. Click the Arrangement tab and drag the TV's display icon to the desired position relative to your primary monitor.
5. Troubleshooting:
If you encounter any display issues, like no signal detected, make sure the cables are securely connected at both ends. Try changing the resolution or refresh rate of the display in your graphics card's control panel. Ensure that the HDMI-to-DVI adapter supports HDCP (High-Bandwidth Digital Content Protection) if you're using a TV that requires it.
This method allows you to connect your PC with an 8400GS graphics card to an HDMI TV, enabling you to enjoy content on a larger display.
