The repeater works very well with me. It reinforces a 1080i HDMI signal starting from the PC to my TV via the following link: 1m long HDMI cable, an HDMI jack, a fixed installation 20m long HDMI cable, the HDMI repeater and a deleyCON 4m HDMI cable to the TV unit. All cables comply with the standard 1.4. 25m is the maximum possible in this interconnection. If the repeater can be installed with other cable lengths in the middle of Verbinung, is determined even more possible. If I replace the first 1m long cable with a 2 m long, it no longer works. If I replace the HDMI jack to a second deleyCON Repeater, it no longer works well. I am very happy for the repeaters among others at the price.
