First of all. There is no on-board video. If your system specs are up-to-date, the iGPU (which comes from the intel CPU) AUTOMATICALLY gets disabled when you insert a dedicated GPU. The iGPU should NOT show unless you've specifically changed this in the BIOS and enabled multi-monitor mode.
No did not do that so i did reflash bios back to older version and the other intel gpu is gone now but when go to the latest bios intell gpu show back on screen i have made two vid please see bot to see what mine issue is
Works fine here, same board. Same CPU, only difference is i'm using Corsair dominator ROG edition ram and mine's a 1080 A and not a TI. Perfect video from the start, and i'm using dual monitors
so i think i know why now what is causing the issue i noticed that when i update the bios in the bios arae its not alway 100 % good so i did it via reflash bios with a usb stick so this what i did an learnd i also forgot about this and HOPPER64 told me about it gave me some extra usefull tips and then i remmembered that i can try that option also but now i got it fixed
is update to latest all drivers check that
shutdown the pc remove powercord pres start buton few times to drain all power then press cmos clear button then put usb in with the latest bios in the bios usb port press and hold bios button on i/o shield wait till it flashes 3 times and the wait untill the light does not flash anymore then remove usb and cable once more and clear cmos then put back powercord start pc
