Question Display cable was replaced with a new one and PC won't boot.

Hi Everyone,

I've been recently getting black screens and loss of screen output whenever my PC case was physically bumped or moved. I isolated this to the cable; whenever I touched the cable, it momentarily disconnected. It's an Unbranded display port, Not even sure what version.
So I've bought a new display cable 1.4, When I plug it in, the PC doesn't like it, The monitor receives nothing and my PC falls into a constant boot cycle.

The Monitor I have - HP Omen 27i G -Sync 165hz. 1440p.
GPU - RTX2070 super.
My GPU drivers are up to date.
The Old Display port cable still works when I switch it back
Can't use the motherboard port as I don't have an igpu
Don't have access to HDMI cables.
I tried the NVIDIA Graphics Firmware Update Tool but that's not compatible with my GPU

Does anyone have any suggestions on what I could do to get the cable to work?

check if the GPU is still plugged in thoroughly

check with a different monitor/TV

plug in the cable in a different port of the GPU

your new DP cable might be faulty
your monitor´s DP port might be faulty
your GPU´s DP port might be faulty

Well, on the assumption that my old cable still works fine in the same port on the monitor and GPU. I would rule out those being faulty.
The new cable could potentially be faulty but sadly I don't have a separate monitor to test.
I will try with different GPU Display port

So I tried a different port and with the key bind to restart the graphics driver and it seemed to have worked 🤣
I've now switched it between the multiple output ports on my GPU and they all work fine too!

So strange how these systems just throw up problems for the sake of it
