Heavy screen flicker - Installation of RHEL 7.5 from Boot USB

Hey everyone,

This problem seems to be intermittent, but when I use the RHEL 7.5 boot usb I get heavy screen flicker and I can't actually look at it.

I just reboot a few times and it goes away. still it would be great to somehow figure out a way to avoid it, perhaps with a reduced resolution mode.

I'm wondering if anyone else here has observed this.

I have an HP Z8 with 2 Nvidia 1080 TI cards in it, and the display is plugged into the first port of card 1.

Thanks for any suggestions!
