HD7650M not giving full resolution

I haven't been able to find anything online about my gpu, other than the fact it needs High Sierra. I'm stuck at 1024x768, and it reports 3mb of vram. With the -wegnoegpu bootflag, the system wont boot. I dont mind disabling it, but I'm gonna need help doing so.

HP Probook 6570b

AMD HD7650m
