How do i increase ram on my standalone? Its greyed out as 4000mb in qubes settings.

Did you shutdown the qube before trying to change the memory?

Gpu passthrough only works when switchable graphics are selected instead of discrete graphics on uefi settings (to show both gpus obviously(

However external monitor doesnt work unless…

Either

1. Discrete graphics is set
2. Or switchable graphics is set but rd.qubes.hide-pci:0a:00.0 is removed from kernel command line at boot

is it not possible to use gpu passthrough and external device at the same time?

You want to use external monitor in dom0?
Maybe the external monitor port is wired directly to dGPU so if you passthrough dGPU to the qube then you won’t be able to use external monitor in dom0.
But you can try to passthrough iGPU to the qube instead of dGPU and use dGPU in dom0, then you may be able to use external monitor in dom0.
You can use virtualgl in your qube with GPU passthrough so you won’t need separate monitor for it:

Seamless GPU passthrough on Qubes OS with VirtualGL

We are presenting to you a guide regarding GPU passthrough created in collaboration with peers. Qubes OS already has extensive documentation available about GPU passthrough for 3D accelerated tasks but they all require in depth configuration, extra displays, and extra input devices. With VirtualGL (https://virtualgl.org) one can take advantage of the existing Qubes OS framework for audio/display by offloading OpenGL onto the secondary graphics card directly with VirtualGL. This document will mo…

But it’s all is just a guess.
