Recently received my Asus Strix 3080Ti from Overclockers, and I've run into a small problem. Title says it all, for the most part?
If I have the GPU plugged in to my two monitors the way I'd ideally like, it doesn't boot. Not even getting to BIOS. Power On Self Test passes but nothing from there. That's one Displayport out from the GPU to the DisplayPort in on my monitor (Acer VG271UP), and a displayport out on my GPU with a HDMI converter to a HDMI cable to my second screen, a small repurposed Logik TV.
However, if I additionally plug in a HDMI from the HDMI out of the GPU to the HDMI in on the Acer, it boots. Acer auto-switches to the HDMI in for the bios screen, then back to DisplayPort once Windows boots. It's not that the presence of DP is inherently causing the issue, it's seemingly the lack of HDMI.
After a quick google of issues like this people blame the cheap DP cables, they 'provide power' to the computer when they should only do it to the monitor or somesuch...but the weird thing is that this behaviour didn't happen on my old Zotac GTX 1660. That was just plugged in from Displayport to the monitor and DP->HDMI converter to the Logik TV, same screens, same components aside from GPU, the same setup in the first paragraph of this post.
I've updated nvidia drivers on the 3080Ti and assigned screens, but unplugging the HDMI results in the same no-boot behaviour.
Any suggestions? Is it really just down to the DP cables? It's perfectly usable but is there anything to be concerned about if I keep doing it this way?
