Q1. Black Screen, No Image at RX(Common for 4K)

A: The default output resolution is 3840x2160p for 4K RX. When black screen occurs but RUN indicator is still flashing, it means the display doesn’t support 4K, then it’s needed to lower the output resolution, such as 1080P or 720P. Just press and hold the RST button of RX for about 1s to automatically switch to different resolution outputs.
