The first 20 meters HDMI cable which actually works for me and I have tried many. Picture and sound are transmitted without any interference. The cable is very well made and makes a solid impression. I would recommend the cable for all the people who have to bridge a large distance, only recommend. The price is absolutely justified (I've ever spent 3 times a Konkurenz- product and that did not work). Super product, so 5 stars.
My previous setup tests: - Computer with nVIDIA GTX580 with "DVI to HDMI adapter" to SAMSUNG 40 "LCD TV. - Notebook with Nvidia NVS 3100M with "DisplayPort to HDMI adapter" to Asus 27 "LCD Monitor - Computer with ATI / AMD video card with "Mini DisplayPort to HDMI adapter" to Philips 46 "LED TV
