|I decided to hook up my PC to my Samsung TV as a 2nd monitor, but since the distance is longer than a typical HDMI cable, I decided to link 2 HDMI cable together through an HDMI coupler (a 30 feet and a 5 feet cable).|
However when hooked up (1080p@60hz, which the TV supports), the picture on the TV has these white specs and tiny white horizontal lines all over.
I've tried another pair of HDMI cables, and switched to another HDMI coupler, but same result.
But then I changed the refresh rate output to the TV to 1080P@30hz, the artifacts went away!
I wonder if it's because of the length of the cable producing signal problems, or if there's something else evil at play.
Might anyone know of anything I can try to bring it back up to 60hz without the artifact problems?
