Could you share some details about how you do this? Do you need displayport on both ends, and is it a monitor or TV? I have the same machine and a 4K TV with only HDMI-inputs and am curious if I can achieve this is in some way. Switchresx looks really useful anyway, so thank you for that. :)
- alanfranz 7y agoThere's no HDMI 2.0 support in 2015 MBPr AFAIK. So no 4k@60Hz over HDMI. You must get DP.
- jordanthoms 7y agoIf you have a Displayport display, you can use a displayport to mini displayport cable, use switchresx, should work good. If it's HDMI only, as the sibling pointed out the HDMI port won't work. However, Startech makes a displayport to HDMI adapter which works ( https://www.amazon.com/DisplayPort-HDMI-Adapter-Converter-60Hz/dp/B01M6WK3KU https://www.amazon.com/DisplayPort-HDMI-Adapter-Converter-60... ) (just make sure you get one which supports 4k60hz, most DP -> HDMI adapters don't).
- notvplez 7y agoI'll consider this though I it would be probably be sitting unused after trying it anyway as I really have no need for it. Thank you for the information. Just to clarify, we're both talking about a late 2013 macbook pro retina? The other helpful commenter mentions the 2015.
- jordanthoms 7y agoYeah, this is all on the late 2013 15" with the nvidia dgpu - https://support.apple.com/en-us/HT206587 https://support.apple.com/en-us/HT206587 has the official details on this BTW - they state that SST Displayport 3840 x 2160 displays are only supported at 60hz on the 15" from Mid 2014 on, but it actually works on the Late 2013 also with Switchresx.
