If HDCP is not available the screen will go blank or lower resolution please try another set. This product does not support HDMI 2.1 devices and may cause constant signal interruptions due to SCDC checking.
Under 4K@60Hz 4:4: 4 resolution the monitor may not support replug because it needs SCDC handshake to perform different ( 1:40 or 1:10 ) clock/data ratio; you may need a powered HDMI switch or insertor to solve.
