I ordered this product on December 9, received on 15 (with weekends included). Packing in a kraftée envelope and the adapter itself into an elegant white box. Connect HP Elitebook 8440p my computer (windows 7) to a TV Sony KDL 40L 4000: the picture is perfect, clear, more beautiful and contrasting that to my computer either-by the way. Only problem, no sound ... I looked in the Control Panel in the TV settings, changed HDMI cable: nothing works. On the box of the adapter, there are well marked "with Sound". After some research, it would be my computer (HP professional range yet), which would not have the sound on the Display Port output ... so this adapter would not cause! So for now I pass the sound through an ordinary headphone jack cable ... Otherwise if you have a computer capable of offering sound on its Display Port output, go, you will not be disappointed by the image quality CMP-ADAP571 adapter!
