Review on Acer SB230 Bbix Ultra Thin Technology 1920X1080P, 75Hz, Wide Screen, HD by Colin Horn

I bought 2 of them and if I only use one it's perfect, everything works fine. Windows recognizes 75hz right away, my only concern is that if I use both monitors and turn on freesync it will start flickering with every game I play. I even used CRU to change the freesync range like AMD forums said but to no avail. If anyone knows how to solve this I would greatly appreciate it.
