â¨Here are some Tips and Tricks for using your new Mini DisplayPort 1.2 to HDMI 2.0a Active Adapter. Many TV manufacturers (Sony, Visio, LG, Samsun) are labeling their HDMI ports as 4k at 60Hz which are NOT HDMI 2.0 capable. Make sure the HDMI port you are using on the TV is HDMI 2.0 capable and not just 4K at 60HZ capable. HDMI port 4K at 60Hz indicates it is HDMI 1.4 capable of running 4K at 60Hz with color sampling of 4:2:0. Our adapters are full specification HDMI 2.0 and support color sampling 4:4:4 at 4K at 60Hz. * If your TV has marking 4K at 60Hz at the HDMI port, you will need to change the color scheme to 4:2:0 in your NVidia or AMD drives settings then change the refresh rate to 60Hz. * Apple  MacBook Pro and Mac Pro â" For now Apple El Capitan doesn't support 4K at 60Hz out of the box. To be able to enjoy 4K at 60Hz on OSX you need to install SwitchResX to force the 60Hz by creating custom resolution. You can download SwitchResX form madrau.com 1. First I downloaded (and purchased) SwitchResX, but you can download a trial that works for 10 days.â¨2. In El Capitan there is a new security feature called SIP "System Integrity Protection". Unfortunately this prevents SwitchResX from modifying the system files that contain resolution information. But you can temporarily disable "System Integrity Protection" to make changes. Once the resolution has been created and activated, you can turn SIP on again.â¨3. Disabling SIP requires booting into the recovery partition. You boot in recovery mode by pressing CMD + R when starting up your Mac.â¨4. Then open a Terminal window. Utilities->Terminal  and type the command below: csrutil disableâ¨5. To re-enable SIP once the changes have been made; boot back into the recovery partition and set state to enabled: csrutil enableâ¨6. Now boot to El Capitan and open SwitchResX. Select the TV from the pane on the left. Then select "Custom Resolution". I entered 3840 x 2160 and made sure that the Scan Rate for Vertical was set to 60 hz. Scaling is also possible.â¨7. Save the changes (by hitting apply, and rebooting your mac.. it will ask you to save). After the reboot you will see the custom resolution added within SwitchResX under "Current Resolutions" for your TV.â¨* Often TV's have 4 or more HDMI ports, but only 1 is suited for "2.0" standard. * On many TVâs you need to turn on "UHD  Color" manually in the settings of your TV for the HDMI port to which your pc/mac is connected. * Please make sure your device Mini DisplayPort or DisplayPort are version 1.2 or 1.3. * By default some devices have their Mini DP and DisplayPorts configured for DP 1.1 and you need to change to 1.2 manually. * Also it could help when connecting 2 screens, to set the screen connected thru the Adapter as second/secondary screen.
