    DisplayPort 1.2a to 4K HDMI Adapter
    I have a Dell E-Port II Plus docking station with 2 display ports and 2 Dell S2240 HDMI displays. I purchased 2 of these adapters. They worked perfectly allowing me to set-up the 2 monitors in "extended desktop". I would recommend to my friends.

    PROS: High quality, easy to use

    CONS: None at this time

    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.

    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.

    Works great!
    We had a conference room that had great monitors put in but only an HDMI cable connection. Getting this adapter to plug into the laptop's Displayport worked beautifully and now we can enjoy the high quality displays.

    PROS: Easy to use, worked out of the box.
