20 Foot Displayport cables for Acer XB270HU not working

For my Acer XB270HU I’ve tried the following 20 foot cables and neither are working:

#1
Monoprice SlimRun AV DisplayPort Fiber Cable:

#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.
