Macbook pro: red lines on an external monitor on a dark background?

Good day.


Search in the net, didn't find anything similar, therefore, refer to the community, maybe someone had encountered this and successfully resolved.


Macbook pro connected to external monitor Dell LED 23' full HD via an adapter mini-displayport->HDMI. Periodically, the black(dark) background run horizontal red stripes. Because the monitor is new, and hooked up a couple of days as sin on the monitor... hooked up another PC, Samsung 9 series to the same monitor in the same resolution, waste half an hour, none of the strips did not appear (Ubuntu). Therefore, the problem of the monitor disappeared. Then sinned on laying the cables, all laid out separately, so as not intertwined with each other — the result is 0.


In principle, very much proyavlyaetsya, for example when watching movies, when you open iTerm2 in full screen (background black). Even if there is a black window not in full screen, it is also sometimes noticeable.


I will appreciate any thoughts and assumptions. But most will be delighted that will help to solve this problem.

Solution
definitely the adapter. The same thing occurs with a mini displayport to displayport. I would recommend to take the adapter mini dvi to dsiplayport
Indeed, the adapter was at fault. Today I borrowed to check mini-displayport->DVI and everything was just fine. - simeon_Fay commented on October 8th 19 at 00:14

Bad adapter? :)
In fact, adapters from DP to HDMI is usually better than in the opposite direction. DP is a professional connector and HDMI "consumer". - simeon_Fay commented on October 8th 19 at 00:16
while there is no way to check, but as one of the options is possible. - Ashley_Haley commented on October 8th 19 at 00:19
I totally understand, but understanding doesn't solve the problem. - simeon_Fay commented on October 8th 19 at 00:22
