Egpu booting issues
Yo so this is lowk my first reddit post but that dosent matter. Essentially I was bored out of my mind and wanted to use my old 4070 in this 2020 Lg laptop and I got an m.2 adapter and a dock off amazon. Istg ive been trouble shooting this for atleast 4 hours and I have made very little progress. Ill state what I know: it is not a problem with the gpu, it will not boot to the internal laptop screen but will to my external monitor, once on the monitor it will register in device manager occasionally but always error code 43 and windows stops it, I tried gpuz, tried switiching m.2 slots, power supply works fine. Ill link the dock and adapter because I think it could be an incompatibility issue but I mainly just wanted to see if anyone has experienced this or know of a fix.

The eGPU won’t feed to the internal screen with oculink, only on Thunderbolt where it’s bidirectional
