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 DisplayPort output port must be DP 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 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, 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 DisplayPort’s Dual-Mode, the adapters actively convert the outgoing 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 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.)

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

  • 4k 120hz 4:4:4 HDR

    Posted by Unknown on Apr 14th 2022

    First let me say that the product is working perfectly but there is a backstory to this.

    I originally bought this in October of 2021 and was disappointed that it was only passing a 4:2:0 signal from my 6900xt to my LG C1 and had intended to return it (even received an RMA). I changed my mind on the hope that it was a firmware issue that would be resolved as a support e-mail had said the issue may be with LG OLEDs at that time.

    Well, I don't know which firmware did it but I decided to try this again tonight on a whim and it works great.

  • DP to HDMI

    Posted by Elton Roy Hyland on Sep 11th 2021

    These do work as suggested however please make note that they DO REQUIRE an additional USB port. These are ACTIVE (powered) adapters and I use 3 for my home cockpit. So I needed a new hub to power them. They work as described.

  • Works perfect!

    Posted by Unknown on Sep 7th 2021

    4k and HDR without problem.

  • Works as Expected

    Posted by Jeremy on Sep 6th 2021

    I was looking for a DisplayPort 1.4 to HDMI 2.1 to display 120Hz HDR. This adapter works like a champ! I would highly recommend this to anyone looking for 4k 120Hz.

  • Finally HDRRRRR :)

    Posted by GeorgeW on May 2nd 2020

    Finally 4K 60Hz and HDRRRRRRRR :)

  • it actually works at 60 Hz!

    Posted by Leala on Apr 7th 2020

    It actually works!

    tested with:
    Sapphire Pulse RX Vega 56 graphics card (display port 1.4)
    Vizio E65 TV
    25 feet HDMI extension cable + 3 foot HDMI patch cable = 28 feet total

    Verified working:
    3840×2160 at 60 Hz SDR ( aka HDMI 2.0 )
    3840×2160 at 60 Hz HDR ( aka HDMI 2.0a )

    Absolutely delighted. My graphics card could not reliably hold a connection at 28 feet of cable with anything greater then 1080p, but this dongle does it easily with 4k HDR at 60 Hz!

    I have purchased other adapters claiming HDMI 2.0b, but none were able to do this even with a 6 foot cable. Just delighted with this one!

  • High Quality!

    Posted by Paul on Apr 24th 2019

    Great product and fast delivery. I thought I was going to have to wait weeks before it arrived from China. No, came from right in Ohio, USA. Saved me from down time with fast delivery.

  • Works as advertised! I needed this for my Titan ...

    Posted by Louis on Mar 11th 2019

    Works as advertised! I needed this for my Titan X Pascal because I'm using HDMI for my 4K display and needed another HDMI port for VR and Titan X Pascal only has one HDMI port. I have it plugged into the display port and my DXDiag is saying my display is 3840 x 2160 @ 60Hz.

  • Excellent Product

    Posted by Travis White on Mar 9th 2019

    Excellent product and works as advertised, but it took some finessing on my part. If you're like me and running a haswell i7 with 4600 graphics (or similar cpu) on a windows based laptop, this adapter will not work out of the box for you. Step one is too make sure you're using the proper hmdi 2.0 port on your monitor/tv. (mine is hdmi 1 port on my vizio tv). Then you'll want to 'search for updates' for your intel graphics. After that open the Intel HD Graphics control panel. > go to display > custom resolutions > set the width to "3840" and the height to "2160" and refresh rate to "60" (**make sure the correct display is selected in the display drop-down menu on the left hand side**) > next you'll want to set the 'Timing Standard' to CTV-RB (VERY IMPORTANT) > finally click add and go back to general settings. Select the resolution you just entered and the refresh rate should be available. I hope this helps!
