Do I have to have an external monster to use an egpu after connecting it to the laptop?
I think you’re saying monitor, so no, you can use the built in display with an egpu, albeit at reduced performance compared to an external monitor.
If you’re not, I prefer to keep my monsters external.
Yeah I meant monitor, was on a phone with autocorrect.
The reason for the reduced bandwidth (and thus performance) is that it needs to send all the information to the GPU for it to render, and then also receive the frame information over the same cable. You probably already figured this out, I just thought I’d mention it though
