Product Description

The Plugable mDP-HDMI active adapter allows you to connect your Mini DisplayPort/Thunderbolt-enabled computer or tablet to virtually any HDMI display. As more and more system manufacturers such as Microsoft, Intel, and Apple include Mini DisplayPort and Thunderbolt outputs on their systems, Plugable’s active adapter enable you to continue to utilize your existing HDMI displays while minimizing potential compatibility issues that can be caused by low-cost, low-quality “passive” adapters.

Our active Mini DisplayPort to HDMI adapters are capable of supporting up to a 594MHz pixel clock and allow resolutions up to 3840×2160@60Hz (4K) (most inexpensive “passive” adapters on the market, also known as “level-shifters” or “Type 1” adapters, have a maximum resolution of 1920×1200). Supports pass-through of LPCM/HBR audio up to 8-channels and 192kHz sample rate.

Our 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. The adapter is also AMD Eyefinity and Thunderbolt compatible. Please see the compatibility section below for important information on Mac/Thunderbolt compatibility.

DisplayPort and Mini Display Port to HDMI 1.4 Older Revision

Our Mini DisplayPort to HDMI 2.0 adapters replace the previous version of mDP-HDMI adapters that utilized an HDMI 1.4 output port. Our new HDMI 2.0 revision improves upon the maximum resolution that our adapter is capable of supporting.

As these two versions of our adapter have an identical form factor, the primary identifying factor to differentiate the revisions is noted by the “Rev B” located on the back of our new HDMI 2.0 adapter.

Compatibility

These Plugable active Mini DisplayPort to HDMI adapter should work with virtually any Mini DisplayPort/Thunderbolt-enabled host and HDMI display, regardless of which operating system is in use. Though please note that system will require functional graphics drivers as normal.

Available resolution options will be determined by the specifications and abilities of your computer/graphics adapter, attached display as well as ensuring an HDMI 2.0 capable cable is being used if 4K@60Hz resolutions are desired. I.e.; if the graphics adapter in your system is only capable of outputting a maximum of 1080P to an external display, the Plugable active adapters will not allow you to exceed this limitation, regardless of the specifications of the attached monitor.

Apple Notes: This adapter works for display (without audio) up to 1920×1080 on Apple Thunderbolt ports (Apple Thunderbolt extends and is compatible with DisplayPort). Please be aware that with update to OSX Mavericks, Apple disabled 4K video output on the vast majority of Mac models – even models which previously were able to output 4K. 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. Also, audio will not be passed through the adapter to an attached HDMI display on Mac systems.

FAQ

Multimedia background. 4k resolution concept
Q: What’s the difference between an active and passive adapter?
A: DisplayPort is a very interesting standard. It has a function known as “Dual-Mode” or “DisplayPort++/DP++” which allows other signal types to be passed through the DisplayPort connector, including TDMS which is the signaling required by HDMI and DVI displays. Passive adapters rely entirely upon the “Dual-Mode” DisplayPort functionality in conjunction with a voltage boost (DisplayPort natively has a 3.3V output, where HDMI requires 5V). When outputting a TDMS (DVI/HDMI) signal through Dual-Mode, most DisplayPort sources as well as the inexpensive passive adapters on the market are limited to a 165MHz clock rate. This limited clock rate generally limits the maximum resolution to 1920×1200 and reduces the maximum available color-depth to preserve the limited bandwidth.

Some mid-range m DP -> HDMI adapters (whether these qualify as “active” or “passive” is a subject of much debate and confusion) are capable of operating at up to 300MHz, but ultimately they are still reliant upon the Dual-Mode functionality of the host to transmit the TDMS signal required for HDMI/DVI displays.

Plugable’s mDP-HDMI adapter is truly active. Rather than relying upon passing a TDMS signal via DisplayPort’s Dual-Mode, the adapters actively convert the outgoing DisplayPort LVDS packets into the necessary TDMS signalling. With an internal clock rate of up to 594MHz, our adapters support all the “must-have” features of HDMI 2.0, with resolutions up to 4K@60Hz, steroscopic 3D support, and higher color depths.

Q: Why does the product information state “Audio will not be passed through the adapter to an attached HDMI display on Mac systems.”?
A: Apple transmits audio over DisplayPort/Thunderbolt in a unique way. Implementing support for this feature on Apple systems would have resulted in the adapter no longer qualifying for VESA (DisplayPort) certification.

Q: Does the Plugable mDP-HDMI adapter support AMD Eyefinity setups beyond two monitors?
Yes! AMD Eyefinity will allow up to two “legacy” display connections (HDMI, DVI, or VGA). The third connection must be native DisplayPort, i.e.; not Dual-Mode/DP++ carrying an HDMI signal (since that would count as one of the two “legacy” displays). When using our active adapters, the video card will not need to utilize one of the legacy connections, but instead will address it as a native DisplayPort display. (Please note: per AMD, their graphics cards support a maximum of two active adapters.)
