4 ms·I have an LG 5k, too! And it only happens on that monitor - my LG 4k over HDMI is fine.by meepmorp 6y agoI have an LG 5k, too! And it only happens on that monitor - my LG 4k over HDMI is fine.astrange 6y agoIt's because the 5K monitor is actually two monitors taped together ("multi-stream transport").brigade 6y agoIt is two streams but it actually isn’t MST. It’s two independent HBR2 links; MST would have been two streams over one HBR2 link, which doesn’t have the bandwidth for 5k.
