TIPS: Here are solutions about frequently questiones answers.

1. There are some 4K TV HDMI function factory settings that do not have all the features of the HDMI 2.0 version. You need to enable all HDMI 2.0 features in your TV settings by yourselves, such brand as TCL, Sony, Sharp, etc. These TV could have all the features of HDMI 2.0 after enabled in setting and also could watch 4K 60hz (HDR10, Dolby Vision, HDCP2.2). The HDCP 2.2 is not defaulted, be sure to go into settings and change it.
2. Some monitors and TVs have multiple HDMI ports, but only one HDMI port is HDMI2.0, which supports HDCP2.2. Please try another HDMI port to plug in the HDMI cable.
3. Sometimes when the HDMI cable is inserted, the player fails to read the TV's EDID and cannot display 4K or a black screen. Please replug the HDMI cable and let the player read the TV's EDID again.
4. HDMI adapter or HDMI switch or HDMI plate will weaken the HDMI signal, causing a black screen or screen cut in/out. Please use only one HDMI cable, one end connected to the player, the other end connected to the screen, without any HDMI adapter or plate，and so on.
5. To use ARC(eARC), first plug the HDMI cable into the HDMI port of a TV that supports ARC(eARC). Second, enable ARC(eARC) in the TV's settings menu. To use CEC, enable CEC in the TV's settings menu.
