It is compatible with 8K@60HZ and 4K@120HZ, clearly displays every particle, and accurately processes every signal source.

【Upgrade Revolution----HDMI 2.1】 CYANMI 8K HDMI Cable conforms to the standard HDMI 2.1 version.

Precautions before purchase

1. Confirm whether the HDMI interface of the devices at both ends supports the HDMI 2.1 specification. Note that 8K can be transmitted only if the devices at both ends support it. Confirm the specification you need to transmit,

If the specification is uncertain, it is recommended to use the equipment wiring connection for verification first;

2. Confirm whether to connect HDMI extension cable or HDMI wall panel and other extension accessories. If there is such connection, it will cause compatibility problems, and it is not recommended to purchase,

3. Confirm whether to connect electronic accessory products such as docking station, switch, distributor, matrix or adapter cable. If there is such connection, it will cause compatibility problems. It is not recommended to purchase,

Precautions for installation and use

1. Pay attention to the direction before installation and use. The "Source" sign end connects PC, game console, set-top box, Blu-ray DVD and other devices, and the "Display" sign end connects TV, display, projector and other devices;

2. Before installation and wiring, pay attention to equipment test and verification. Simulate the connection of equipment at both ends to be used. First test and verify whether it can be transmitted and whether the specification can be reached,

Pay attention to the lines to be laid. Each line needs to be tested and verified;

3. Please read the instructions before installing the pull wire and wiring, pay attention to the pull method and corner requirements, and protect both ends

Precautions for product use

1. Pay attention to whether the 8K channel at both ends of the device has been opened, especially at the TV end. Some devices will be automatically opened, and some devices need to be manually set to open;

2. HDR does not support: check whether the devices at both ends support HDR, check whether the signal source device turns on HDR, and check whether the display device has turned on enhancement or color depth optimization mode;

3. CEC does not support: most of the devices at both ends are compatible with the same brand CEC functions, and many devices across brands are not compatible with CEC;

4.4:4:4 or 4:2:2 color gamut is not supported: it can only be supported by equipment at both ends, and equipment wiring may be verified first;

5. No signal: check whether the input and output of the device is the current HDMI port, and set it to the current HDMI port; Check whether the direction of the wire is inserted reversely; Check whether the input and output ports are dirty and plugged in place;

You can try to switch to other HDMI ports for verification;

6. Display screen jitter or noise: check whether the input and output HDMI ports are loose, or try to plug and unplug them again at both ends (first plug the display end, then plug the signal source end, and then do protocol communication again);

7. VRR, QMS and ALLM are not supported: it needs to be supported by both devices. Does it support querying device specifications

8. Precautions for the use of PC graphics card: 8K output supports independent use. If there are two or more DP ports+HDMI ports on the graphics card, the output resolution of two or more ports at the same time will fall below the 8K standard;

9. Precautions for use of PS5 game console 4K/120Hz: 4K/120Hz can be turned on only after purchasing the official Sony game (supporting 4K/120Hz);
