HDMI cables are undoubtedly the current standard for digital image transmission. TV sets transmit not only the picture, but also the sound. The picture/sound transmission is of course also possible with a beamer, but projectors usually offer less well-equipped internal speakers.
In the age of 4K transmission, an HDMI cable with HDMI 2.0 and HDCP 2.2 certification is indispensable.
