The 6ft High Speed HDMI Cable is one of the cable accessories sold by Philips that claims to support 4K Ultra HD and 1080p HDMI outputs as well as Ethernet on its packaging.
The Philips 6ft High Speed HDMI Cable also comes with gold plated connector design and lossless surround sound capability that may help to further reduce signal interference resulting in better quality signal transmission when connected to your HDMI enabled 4K or HD TV's or displays, and computers or other devices.
Using the GRL DI20 cable tester to test the insertion loss through the Philips 6ft High Speed HDMI Cable in comparison to the Hama 1.8m High Speed HDMI Cable, we can see the Hama 1.8m High Speed HDMI Cable has much better overall signal integrity performance than the Philips 6ft High Speed HDMI Cable even though they are the same length. The Philips 6ft High Speed HDMI Cable although cheaper has higher loss under 10 GHz compared to the more expensive Hama 1.8m High Speed HDMI Cable (see review here).
