So, I am considering preordering a Framework 16 with the AMD Radeon™ RX 7700S model but I have a concern: how many external displays can it run simultaneously, specifically on Linux? I cannot find documentation answering this question anywhere. Thanks in advance.
It can run two displays directly on the 7700S; the internal screen and one external screen using the port on the back. Any of the other ports go through the integrated 780M.
The dGPU supports 4 displays. The internal display does count towards that when the display is on, however I expect that when the lid is closed it probably won’t.
There is physically only one port on the dGPU (and the ports on the laptop connect to the iGPU), however you can use an MST hub (built in to most docking stations) or monitors that support daisy chaining.
