Maybe then VGA over DVI will work?

Funky frank Posted March 24, 2015 Author Share Posted March 24, 2015 Hey guys, my patch above only works with a hmdi beamer device, but not with a newly connected 1280x960 tft screen. I connected this screen to the hdmi port and to the dvi port of the screen, using a dvi-hdmi adapter. The screen won't detected in OSX 10.9.4 and sometimes the screen shows an error like "wrong rate". On boot the screen works. The DVI main ports works fine. Any ideas whats wrong with my numbers for the HDMI port (second line)? Cannot find any error.... Thanks! Link to comment Share on other sites More sharing options...
Slice Posted March 24, 2015 Share Posted March 24, 2015 As I see all forum members have problems only with HDMI, video or audio. Link to comment Share on other sites More sharing options...
