dp to hdmi 4k 60hz on mac pro


I have successfully used the dp to hdmi adapter on my 2013 mac pro to connect to a 4k lg tv on mac osx at 60hz. However, in bootcamp in windows i am limited to 24hz. Any ideas?



Hi Steven, thanks for posting! Sorry to hear that you aren’t able to select a 60Hz refresh rate when in Bootcamp on your Mac Pro and I will be happy to help!

Thank you for the description of the behavior you are seeing. I’d expect things to work to display 4K@60Hz while in Bootcamp, as well, assuming that the Windows installation is updated as well as the internal graphics driver for Windows.

Based off of this, we’ll want to examine some log files from Windows to see if they can tell us what is happening. To help us do so please download and run our diagnostic utility PlugDebug --> http://plugable.com/support/plugdebug with everything connected. Please send the file that is created on your Desktop by sending it to our direct support email address at support@plugable.com with ‘Ticket number 161944’ in the subject line so we can match everything up. We’ll examine the logs and determine next steps from there.

Thank you,
