The correct audio channel needs to be selected on the switcher, often corresponding to the HDMI input you are using. Check that your PC’s audio output is set to the correct HDMI source.
Advanced Tips for Optimizing Your HDMI Connection
Connecting your PC to a video switcher is more than just plugging in a cable, it is important to understand the best practices for getting high quality and stable video. Here are some important tips:
- Cable Quality: Invest in a high-quality HDMI cable, particularly if using longer runs. Lower-quality cables can degrade signal quality or cause interruptions. Choose a cable rated for the bandwidth that you need for your resolution, at least HDMI 2.0 or higher.
- Resolution and Frame Rates: Ensure your PC’s output resolution and refresh rate are compatible with your video switcher and other equipment involved. You might need to scale down your resolution or refresh rate to improve stability. Common options are 1080p at 60fps for high quality and 720p at 30fps for lower bandwidth.
- Color Space: Be aware of the color space settings (such as RGB or YCbCr) on both your PC and video switcher. Incorrect settings can lead to color inaccuracies in your output. RGB is more common with computer content, while YCbCr is frequently used in video production.
- HDCP: High-Bandwidth Digital Content Protection (HDCP) can sometimes cause issues with the signal, especially if your content is protected. If necessary, consider using a device that strips HDCP from the signal, but ensure that your content is compliant with copyright laws.
- Latency: Latency refers to the delay in signal processing. Some video switchers might introduce a slight latency to process your signal. While slight latency is negligible, in fast paced applications like gaming, latency can have a very negative impact, so chose a switcher that introduces minimal latency. This is a particularly relevant concern for live streams, interactive experiences, and gaming.
