Recommendations

For stable 4K/30 Hz output, use high-quality HDMI cables and ensure source GPUs support 4K at 30 Hz. When using audio formats like Dolby TrueHD or DTS HD Master Audio, verify that the connected devices and playback software support these formats. Place the switch on a flat, ventilated surface and avoid blocking the ventilation around the metal housing.
