Connect to an HDMI Ultra HD display with High Dynamic Range from a Mini DisplayPort-supported computer using the Mini DisplayPort Active Adapter! Designed specifically for those who enjoy high-level computing, graphics, and gaming. HDMI 2.1 up to 48Gbps allows even smooth 8K video playback, especially when combined with a 60Hz frame rate and HDR creating lifelike colors and movements giving users the ultimate visual experience. Converts Mini DisplayPort video signal at up to 8K 7680x4320@60Hz or 4K 4096x2160@120Hz including 1440p at 240Hz. Best of all, the Mini DisplayPort Active Adapter is extremely easy to use and travel with, thanks to its portable size. The Adapter is powered thru a USB Type C to USB Type-A cable (provided with the product).
Last but not least, the Mini DisplayPort Active Adapter supports a 4:4:4 color format, ensuring true RGB vibrant colors, as well as HDR without typical visual color degradation. Audio isn't a concern either with the transmission of up to 8 channel audio for immersive sound.

  • Depress the button on the Mini DisplayPort connector to release the latches and avoid damage when unplugging
  • For HDR function, the source system needs to support Mini DisplayPort™ 1.4 and the screen needs to have support for HDR and HDMI™ 2.1

Q: I am only getting 4K@60Hz when using the UPTab Active adapter. How can I get 4K @ 120Hz?

There are several different reasons why a 4K display would be limited to 4K@30/60Hz using our adapter. We would recommend first checking:

  • The Mini DisplayPort output port must be mDP 1.4 compliant to get 4K @ 120Hz with HDR.
  • System specifications to ensure that the internal graphics processor can support 4K @ 60Hz and that the output port on the system/GPU can support 4K @ 60Hz.
  • Monitor specifications to ensure that it can support 4K@120Hz from the desired input port. HDMI input ports must be HDMI 2.1 specifications.
  • For HDR to function, the source system needs to support Mini DisplayPort 1.4 and the screen needs to have support for HDR and/or HDMI 2.1.
  • Ensure that the HDMI cable is HDMI 2.1 Certified.

If both the system's GPU, Mini DisplayPort output port, and the monitor claim support for 4K @ 120Hz, please check the Windows Advanced Display Adapter settings to ensure that 120/60Hz is available and selected from the drop-down list.

If 120Hz is not listed and you are connected to our adapter with an HDMI 2.1 cable, please double-check that the monitor has HDMI 2.1 ports. Additionally, some 4K TVs and monitors must enable an “HDMI 2.1,” an “HDMI UHD Color” or “Ultra HD/UHD Deep Color” (or similar) setting for 4K@120/60Hz to work via HDMI. Please consult the monitor’s manual and check the monitor’s menu settings to see if there is an applicable setting.

UPTab adapter is truly active. Rather than relying upon passing a TMDS signal via Mini DisplayPort’s Dual-Mode, the adapters actively convert the outgoing Mini DisplayPort LVDS packets into the necessary TMDS signaling. With an internal clock rate of up to 594MHz, our adapters support all the “must-have” features of HDMI 2.1, with resolutions up to 4K@120Hz with HDR, stereoscopic 3D support, and higher color depths.

Q: Does the UPTab (B014E8ZC7E) 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 Mini 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 Mini DisplayPort display. (Please note: per AMD, their graphics cards support a maximum of two active adapters.)

Q: Does the UPTab (B014E8ZC7E) adapter support 4:4:4 color/chroma sampling?

Yes! Our adapter supports 4:4:4 chroma sampling at 4K @ 120Hz resolutions at 8bit color depth (8bpc). Please be aware that connected display\TV must also support 4:4:4 color depth and the HDMI cable must be HDMI 2.1 capable while connected to an HDMI 2.1 input port on the display.

Q: Does your adapter support HDR?

Our adapter does support HDR imaging (High Dynamic Range). HDMI 2.0b is the minimum specification for supporting HDR.

Q: What are supported HDR Standards?

Our adapter supports High Dynamic Range (HDR) standards: Dolby Vision HDR, HDR10, HDR10+ and HLG

  • works a treat on my mac pro with Samsung curved 55" 4k TV

    Posted by andrewmcv on Feb 6th 2016

    Fantastic cable & adapter - i got UHD@60Hz within minutes. One trick is i needed to switch the Samsung TV to UHD color.

    The cable is outstandingly well made - it's very professional looking. I literally have the perfect picture now.

  • 4k@60hz confirmed

    Adapter works as advertised. I have using a Microsoft Surface Book, and can output 4k@60hz.

    Product itself is built well, good housing.
