    #2
    Tripp Lite DP > HDMI cable:

    In combination with Active HDMI > DP converter:

    These cables are working with my other monitors. My 10 foot CableMatters DP > DP cable works with the Acer monitor, but I need around a 20-foot cable.

    You can view the specs of the Acer XB270HU here; the only port is a Displayport. No HDMI:

    Any suggestions? I am willing to pay as much as $250.

      In reply to 20 Foot Displayport cables for Acer XB270HU not working

      Asked myself what is the maxinum length of one of these cables?

      A quick Google search brought this up

      This decision limited confusion in the market place, but set the maximum limit for a certified DisplayPort cable at 5 metres. Using couplers to join two certified DisplayPort cables together for a run longer than 5 metres will result in loss of signal. There is currently no workaround for this length limit.Nov 11, 2013

      But apparently some cables are better than others and a longer length may be possible though I personally feel that 20 feet would be way over the upper limit.

      However I may be completely wrong as I have never tried to use one of these cables anywhere near that type of length.
