macmanroy Posted June 17, 2013 Share Posted June 17, 2013 I have just finished updating to mavericks but am having a slight problem. I have a gigabyte z77n motherboard and use hd 4000 integrated graphics. One hdmi is connected to a monitor and the other hdmi to a tv. When only one is connected everything is fine but when I connect the second hdmi the screens go crazy. The image splits and is made of horizontal lines. Any ideas on how to fix this?

Macboy123 Posted July 1, 2013 Share Posted July 1, 2013 Macbook Pro Retina Late 2012, Mavericks 10.9 DP2, HDMI Output to TV Samsung 46" FullHD Same Problem when connecting the HDMI cable with the Macbook HDMI port. Screen starts flickering, is splitted into horizontal lines. Mouse cursor is not there where it's assumed to be. Clicking and setting some options in Multiple Display Options impossible. Hope they'll fix that in DP3, as i can't use TV as second screen at the moment.

Nanael Posted July 2, 2013 Share Posted July 2, 2013 Hy, The MacBook pro retina is early 2013 and I have no problem with the HDMI or dp to VGA. I have tried on my 66" HDTV and video projector. You should try to switch from hd4000 to the NVidia 650m? but my mbp was using the hd4000. Good luck Link to comment https://www.insanelymac.com/forum/topic/289918-dual-display-problem/#findComment-1929584 Share on other sites More sharing options...
