HDMI 2.0 repeater for longer cable runs
In particular, audio-video signals in 4K resolution (up to 4,096 x 2,160 pixels, also known as UltraHD) require new hardware that meets the HDMI 2.0 standard. This is the only way to guarantee transmission rates of 18 Gbits/s. For longer cable runs of more than 10 m, a so-called repeater is required, which decodes, corrects errors and encodes the HDMI signal again. This means that a greater distance can be bridged with passive cables. With resolutions lower than 4K, the requirements are lower, so that even longer cables can be used here. The maximum range can be achieved with different cable lengths at the input and output of the repeater:
You can use 2 different length HDMI cables with the repeater. The longer HDMI cable should be used between the signal source and the repeater. If you have long distances, you should also only use high-quality HDMI cables. The quality of an HDMI cable is often difficult to assess. In general, the larger the cable diameter, the better the signal. Good shielding also increases the diameter. You can recognize a good cable, for example, by the designation AWG24 copper inner conductor. That means the wire cross-section is 0.2 mm².
The HDMI 2.0 repeater is fed from the signal source via the HDMI cable, because this also transmits electricity. This is made possible by using a new, highly efficient chipset with low power consumption. Separate switching on and off is no longer necessary and no additional power connection is required.
All HDMI video and audio data from the source device are passed on 1:1. This applies to digital sound formats, image resolutions and any copy protection. The repeater can also be used for UltraHD with HDR (High Dynamic Range). As a result, the target device has the same signal quality as with a short cable connection. There is also no noticeable time delay (latency). HDMI-CEC control signals and the audio return channel ( ARC ) are also supported - but not amplified.
As an alternative to an HDMI repeater, HDMI fiber optic hybrid cables have now become affordable. However, such cables should be used directly from device socket to device socket - without extensions or adapters.
