Hello. I have a MacBook Pro Retina 15″ Mid 2015 with AMD Radeon M370X + Intel Iris Pro.
I am connecting it to a Samsung 4k TV (40JU6000). I am getting 3840×2160 at 30hz.
Are there any products that would allow me to get 60hz?
On the TV;
* Set Edit Device Type to PC
* Please use TV’s HDMI (MHL) port for HDCP 2.2 protected content.
* HDMI UHD Color Allows you to set the HDMI UHD Color mode to On or Off for each HDMI connector on the TV. When set to On, the TV optimises processing of UHD 50P/60P signals.
For setup with TV it normally works best to make a custom resolution for 3840x2160p at 60Hz with Timing Standard set to CVT-Redeceud Blanking (RB). Since MAC OS X does not give you that option, you will need a program like SwitchResX to do that.
