First of im new at posting on these forums, that just because I never had to post because i would usually find my solution with previous posts made on this on this very helpful forum. That said my problem is the internet is really slow when I connect my macbook to a my samsung 24" monitor. Super slow and when I disconnect, the internet is perfectly fine. I use speedtest.net to measure the speed and with the monitor I get usually around .05 Mbps to 3Mbps, without 12-19Mbps. Now I've searched this topic and found some people having this same issue but still no solution can anyone help us out, any help would be very much appreciated. If you need any more details on my problem please post thank you.
