The Dreaded Blackscreen - Past solutions all failing

Hello, first, I would like to start by saying that I have further diagnosed the problem. It is completely uncorrelated to any of the advice you offered. While I do not like randomly criticizing people, the way you write makes it clear that you are not from any kind of computer science background. I would advise against giving people with various types of issues the same set of advice for them to try. While I understand it comes from a desire to help, it can waste people's time.

Anyway, here's what I've found out through further research and experimentation: When both Integrated and Dedicated Graphics are enabled in a laptop (called Hybrid graphics by most), the laptop's main display runs on the integrated graphics while any displays plugged into HDMI ports are processed by the GPU. (A similar situation can occur when two displays are plugged into separate GPU's in a multi-GPU desktop setup, though this is much rarer nowadays.) In my situation with swtor, the chain of graphical info which should look like [Game -> GPU -> CPU -> Display] instead is carried through as [Game -> GPU -> Dead end], because the display is ran on the CPU's Int. Graphics, and the GPU fails to feed it the information.

The ideal solution would be to somehow force the laptop's display to be ran via the GPU, but I do not know how to do this. (In linux I could do this via xorg.conf but I know of no equivalent in windows.)

The realistic solution, which I will sadly have to use, is to simply disable the integrated graphics and switch to using only discrete graphics.
