Crash useing Extend Display to active perform mode as well as separate window mode

Hi, everyone; I have a issue when I use extend displays to active perform mode or separate window mode even to open OP crete dialog TD just crashed. but is ok to use the main display to active perform or separate mode. I’m Using Alienware Area-51m R2 with Rtx 2080 super, and my TD version is TouchDesigner.2020.24520. I try to update the GPU driver, and change HDMI Cable but still the same issue.

I use surface book 2 with same TD version to make the test, its turns out everything is fine. So i am wondering is it the problem comes with My Alienware or the GPU.

It‘s there anyone had same proplem, please help. it’s urgent.
sorry for the poor english.
