Product Description

The Plugable DP-HDMI active adapter allows you to connect your DisplayPort-enabled computer to virtually any HDMI display. As more and more system manufacturers such as Microsoft, Intel, and Apple include DispalyPort outputs on their systems, Plugable’s active adapter enables 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 DisplayPort to HDMI adapter is capable of supporting up to a 300MHz pixel clock and allow resolutions up to 3840×2160@30Hz (4K) (most inexpensive “passive” adapters on the market, also known as “level-shifters” or “Type 1” adapters, have a maximum resolution of 1920×1200) and 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 are compliant with VESA Dual-Mode DisplayPort 1.1, High Bit Rate (HBR), and HDMI 1.4 standards. The adapter is also AMD Eyefinity compatible.

Compatibility

The Plugable active DisplayPort to HDMI adapter should work with virtually any DisplayPort-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 and attached display. 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.

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 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 DP-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 300MHz, our adapters support all the “must-have” features of HDMI 1.4, with resolutions up to 4K, steroscopic 3D support, and higher color depths.

Q: Does the Plugable DP-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 adapter, 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.)
