How to fix monitor not waking up on displayport ?

I have a Sapphire RX580 and a Samsung CF791 monitor connnected via displayport. I don't put my computer to sleep but I do let the monitor sleep after 15 minutes of inactivity.  The problem is when I try to wake up my monitor, 60% of the time the monitor does not wake up and sometimes I get a "link failure" message.  I've had this problem in the past with a Dell 2408WFP and a XFX RX480.

 

I have the latest AMD Radeon drivers installed and I have the latest Samsung CF791 driver installed.  Anyone know how to fix this problem ?
