rhcp011235 Posted December 25, 2015 Share Posted December 25, 2015 Have you looked in system prefs / monitor Yes. I have done all this. I even swapped out my 970 for the same card. Thinking perhaps I had a bad card. We also flashed the latest firmware onto it. Link to comment Share on other sites More sharing options...

Apple So you cannot get 60HZ from HDMI? Also, how would i get 60HZ? and THANKS Also, I am going to include a video of this flicker effect i am talking about. Look for horizontal lines flickering this is what I'm talking about, also the display will even go out at times. http://rhcp011235.rocks/2l451q3s2D1X Link to comment Share on other sites More sharing options...

rhcp011235 Posted December 25, 2015 Share Posted December 25, 2015 only the 60Hz HDMI for a resolution 1920x1080. For your screen plug it in 4K on display port But, there is no DP 1.2 -> HDMI 2.0 Adapter out yet. This TV doesn't have a display port. (Thats one of my issues) Secondly, is that flickering (thats my biggest issue) - If you have any damn idea what that is You have been MOST helpful here. BTW: I am not using a real mac here (Using a HackPro) that i built with the above card. So i figured id get 60HZ out of the HDMI 2.0 port. but i guess the OS itself is holding me back? Id be PISSSED if i bought a Mac Pro and this didn't work! Link to comment Share on other sites More sharing options...

Ideas anyone? Also, Ideas to get 60HZ on my 4K? AFAIK. DP -> HDMI (doesn't do 60HZ since they are not HDMI 2 yet) Link to comment Share on other sites More sharing options...

rhcp011235 Posted December 25, 2015 Share Posted December 25, 2015 DP=>HDMI I have seen these. But, they don't do 60HZ as far as i know. You need an active DP -> HDMI for it to work. Link to comment Share on other sites More sharing options...
