    BEST ANSWER: Thank you for your question. Yes, you would be able to use an active HDMI cable along with the DisplayPort to HDMI adapter. You would just want to be sure to have the source end of the active cable in the HDMI port on the adapter and the TV end of the cable plugged into your display. The active HDMI cable will not work plugged in backwards.
    Will this work from a xbox1 HDMI to a monitor display port ?
    A shopper on Jan 19, 2017
    BEST ANSWER: No, this adapter converts displayport protocol to HDMI protocol not the other way around like you have asked.

    Doesn't support 4K at 60Hz, otherwise great
    I bought this for 4K (4096x2160, 3840x2160) @ 60Hz support (HDMI 2.0), however this is limited to 30Hz so theres really no point. Only positive is it works and supports audio passthrough.

    PROS: It works at 4096x2160@30Hz
    Support audio

    CONS: Does NOT work at 4096x2160@60Hz (HDMI 2.0)

    Works as expected.
    Using these in trail cameras (Browning and Cabela's). Bought one to verify they would work in my cameras. Once verified, ordered 5 more.

    6 out of 5 stars
    First one was having electrical errors. No products (not even space rockets) are 0% fail. Immediate RMA with free replacement. 2nd one works as expected. No hassle involved. Had reasonably fast shipping into the midwest.

    If i am not mistaken, i am getting 60hz at 1080p.

    PROS: Allows for, and works with Eyefinity triple monitor setup.

    CONS: None

    Title a bit misleading since it only does 4k @ 30Hz or 60Hz/4:2:0
    Device works great for tight spaces (I only had 40mm to work with) and fully supports 4:4:4 chroma with audio up to at least 48KHz 24bit

    It must be noted that this is an HDMI 1.4 device which was more than enough for my needs (1080p TV), but it would be nice if the title for the product said HDMI 1.4 rather than "4k HDMI" as the general consumer has associated 4k+HDMI with HDMI 2.0 (regardless of the fact that HDMI 1.4 can actually do 4k).

    PROS: Works, good for tight spaces, supports 4:4:4 chroma with audio (LPCM up to 8-channel 192KHz 24bit)

    CONS: Title can be misleading to the average Joe as this is an HDMI 1.4 devices

    Simply works
    Works without fanfare or fighting with the settings. I didn't try to send a 4K signal because the laptop graphics card could did not support it.

    Great for a little while.
    These seemed like a great inexpensive option to hook my current monitors to my graphics cards. However after a few months of use they no longer work properly. If they are even slightly nudged while plugging or unplugging something into the back it causes the image quality to degrade or even go out completely until they are moved back into a sweet spot. All issues completely rectified after going to a pair of all-in-one converter cables rather than these adapters.
