Unfortunately, the quality of this adapter is far from satisfactory. After initially no issues were lost, I suddenly discovered a few days ago red pixels at different locations on the screen. After some testing, I've found that this pixel shift and possibly disappear when you move the adapter. Thus, one can here well on poor workmanship and resulting poor contact or similar conclude. Too bad.
(Both the computer and the screen can I exclude a source of error, since they function properly with other adapters or no adapters.)
