IMPORTANT: some USB ports on projectors or TVs are service ports so these may not

provide any 5 volts power, so our DISPLAY HDMI plug cannot turn on. Please make sure

the connected USB can provide the standard 5 volts usually all USB does have.

IMPORTANT: USB POWER must be connected (mandatory) on the DISPLAY HDMI Plug

side as power cannot travel over fiber optics from the source.

11) If NO PICTURE is seen please follow these steps:

a. REDUCE the video resolution of your video source to HD.

Some TVs or Display might not support 48 Gigabit ultra HD our cable does

so it is better to start from the bottom format ( 1080P or 720p ) then when the

picture is displayed, change the settings on the source to find the upper

resolution limit and frame ration supported by the display.

b. Move the source to the TV or PROJECTOR site then use a short COPPER HDMI

CABLE not longer than 10 feet / 3 meters to test the same resolution.

KEEP IN MIND: COPPER CABLE SPEED LIMIT IS 10 GIGABIT/S (4k@30) so the

picture might be working AUTOMATICALLY DOWNSCALED By the negotiation

between your tv and the source because the copper cable limit.

BUT WHEN YOU USE OUR CABLE THERE ARE NO LIMITS, as our cable pass full

18 gigabit/s (4k60) HDR10+ ( 48 gigabit/s HDMI 2.1 ) and 4K120 8K60 ( 48

gigabit/s)

If with an old copper cable the TV or Projector works, but cannot display with

our cable, it is because the TV or Projector cannot handle the higher speeds.

The solution is to reduce the format/resolution on the source so you reach the

limit of the TV or Projector. MANY TVs only does 4K30 4:4:4 8BITS, so to make

4K60 the format must be set to 4K60 4:2:0 8 bit or the TV will not display.
