Trouble with 144hz monitor (occasional stutter)

[GlitchyInk]

Hello, I recently purchased a 144hz monitor (BenQ Zowie xl2411p) and I have noticed a stuttering issue in games. The issue only occurs when there is any movement on my second monitor (60hz BenQ gl2450).
I have tried a lot to fix this issue, even running the screens on separate GPUs but nothing thus far has worked. I'll list my specs below any help is appreciated, Thanks.
Note: even though I'm running three monitors the problem persists with only 2.

I'll try and get it but it wasn't purchased on this account. If you ask for any parts I can probably list them.
I tried attaching a dxdiag.txt file but wasn't allowed.
