Clearly visible quality loss

Even if the price is tempting, the result is unfortunately disappointing. After first connecting I actually thought it would be all right. Picture is there, running.
On closer examination, especially in direct comparison with several short cables, then shows that the image is anything but "fine" is.
I did not think that it can only come through an HDMI cable to a so clearly visible loss of quality in picture.
Instead shows dropped frames or black image I could throughout the image "block noise" and jaggies easy recognize.
I do not know Different production lines was connected a PS3 to a 42 "Full HD LCD. Where the many positive reviews come. Maybe?
The cable is present to me in any case nothing and therefore returns. A star's for the price and that at least one image is there.
