    Does this adapter support the transmission of audio signals?
    A shopper on Mar 9, 2017
    BEST ANSWER: The DisplayPort 1.2a to 4K HDMI Active Adapter does support the transmission of audio signals.
    I need to convert an Nvidia card output that does 4K at 60HZ. Has anyone tried that?
    A shopper on Apr 3, 2017
    BEST ANSWER: It should, but it is dependent on particular setups and devices. I have used them with 4K TVs in the past though.
    I have a monitor with displayport and devices that can output HDMI. Will this work?
    Simon Y on Jan 19, 2017
    BEST ANSWER: No - this works to go between a device with DisplayPort and a monitor with HDMI (so opposite of what you wrote).

    Not HDCP compliant
    I used this to connect a Saphire Radeon HD6770 connected to a Dell 2408 HDMI port. Windows Media Centre reported that the device was not HDCP compliant and would not permit video display. I tried another brand of Active Displayport adapter and had no problem with Windows Media Center. I did not expect this from a Monoprice product and have wasted my money.

    Have 20+ of these and several have caused issues
    I started using these to go with Dell Optiplex 7040 SFF desktops and a dual monitor setup. I have had 5 cause random screen flickering/no signal issues.

    It took some time to narrow down the issue from the video card, HDMI cables, monitors, BIOS and software-related issues. Finally narrowed it down to these.

    Usually, Monoprice have great products- HDMI cables, CAT 5 and CAT6, etc. This is just not one of them.

    Should have re-read specs
    Was using for PC to 4k TV, either 4k@60hz OR 7.1 surround sound. Neither work. 4k@30hz seems to be the highest this support and for sound I can only get 2 channel instead of 7.1.

    Does not do the job
    I have a setup of an active DP1.2a to HDMI converter to HDMI and a HDMI high speed cable to my display. It is working fine with 3840x2160 resolution at 30fps progressive. I was trying to replace the combo with this single cable, but it does not work at all. It cannot even identify the display at any higher resolution than 1920x1080. The cable went to trash...

    won't work with pc
    I bought 2 of these as well as a cheaper one around 5 bucks from monoprice. The cheap one is much better for 2 reasons, 1 it locks in the port and second and most important it works. This product at 15 bucks does not work with any display port in a computer vga.

    Worked great
    This cable worked perfectly to use an HDMI only monitor via a display port out of my graphics card so that I was able to free up the HDMI port for use is VR headset without having to unplug the monitor every time.

    No problems
    Bought three of these a few weeks back and have had no issues. I bought these to use with display emulators (dummy plugs) for Virtual Desktop.

    Super savings. We have purchased a large number of these to save on buying from other suppliers. They work as they should.
