Longer cables may not support 4K 60Hz with this adapter due to the limited power output of DisplayPort computer outputs.Recommended cable length not to exceed 6ft/2m.HDMI 2.0 (sometimes labeled 'HDMI 60Hz') input.4K 60Hz capable display without HDR (See below for HDR limitations and recommendations).Apple computers with Intel graphics controllers and Thunderbolt, Thunderbolt 2, or Mini DisplayPort outputs (see below for known compatibility issues).Intel UHD, NVIDIA, or AMD graphics controller capable of 4K 60Hz output.Recommendations for 4K 60Hz displays: Computer: The adapter is also compatible with both AMD Eyefinity and NVIDIA Surround technologies. The adapter has passed the extensive testing requirements necessary for VESA certification, and is compliant with VESA Dual-Mode DisplayPort 1.2, High Bit Rate 2 (HBR2), and HDMI 2.0 standards.

Additionally some Apple systems will not be capable of outputting audio from Thunderbolt 2 to the HDMI display. Only Macs with “official” 4K support from Apple will be capable of 4K output using this adapter, while most will be limited to 1080P output. Please be aware that with an update to macOS Mavericks, Apple disabled 4K video output on the vast majority of Mac models-even models which previously were able to output 4K. Apple Notes: While our mDP adapters work with Apple Thunderbolt ports, the maximum supported resolution will depend on the model of Mac and monitor in use. This adapter supports resolutions up to 4K (3840x2160 60Hz) refresh rate for computer monitors and televisions with Standard Dynamic Range (SDR), 4K 30Hz with High Dynamic Range (HDR) capable televisions and monitors. Active adapters use an integrated chipset to convert the DisplayPort signal from the computer to a HDMI signal, compatible with HDMI displays. Plugable's Mini DisplayPort to HDMI Active Adapter (MDP-HDMI) allows you to easily connect the Mini DisplayPort/Thunderbolt 2 output on your Mac or PC laptop, desktop, or tablet to virtually any HDMI-enabled display.
