B286HK Severe Flicker with or without input

I have had the unit for about two weeks and have had off and on flickering issues.  Now even plugging it in it begins to flicker incessantly whether it's connected to the GPU or not; I have used HDMI and Display Port cables with no success.  I'm assuming it's something with the firmware, but would take additional trouble shooting advice.  I have added mouse trails, etc.  I can't even access the settings to reduce the refresh rate, as has been suggested on some forums.

    I have a problem like this. If the white space is stretched from the left side of my monitor to the right I get these flashing horizontal lines. They only appear if the color of the page is white...not grey or some other color. If I shrink my browser window so that color is on the end of the screen the flickering stops. After registering the product the I found the latest driver so I installed it...(had to disable Window's security feature of only allowing digitally signed drivers because it was an inf file...unexpected) Rebooted, reseated, nothing has helped. 

     

    driver I'm using 

     

    [version]
    signature="$CHICAGO$"
    Class=Monitor
    ClassGuid={4D36E96E-E325-11CE-BFC1-08002BE10318}
    Provider=%Acer%
    CatalogFile=Acer B286HK.cat
    DriverVer=06/04/2014,1.0.0.0

     

    Really frustrated I'm having to deal with this. If anyone finds a solution please post. Acer ?
