This is well worth the buy. I replaced the OEM HDMI cable from Comcast with this Monster HDMI cable and what a difference. The picture and sound quality is up 200% better. The picture is crystal clear and very sharp, the colors on the TV are so much more brilliant than before. It made the sound more sharp and clear on my 5.1 Dolby surround sound system. The back speakers sound is much louder than before.
