Ouch. Sorry to hear that. I know what that feeling is like. Recently my Surface Pro 6 slipped off the desk onto a stone floor, and has a damaged corner/screen now. Sadly, it happens every now and again. Today’s devices seem far less repairable than older devices.
One option you have is to buy a new device and keep/sell the damaged device for spares to get some money back. Alternatively I don’t know if the Gemini screen is the same specification. That device is currently being sold at a 25% discount. But with the headache of swapping the screens, you are probably back to a similar cost to getting the device repaired by PC. Although, again you would have a device you could perhaps sell for spares.
The other option if no one replies is to take your device apart now, and see if you can identify the make/model number of the screen/digitiser, and then see if it’s possible to source the part(s) from a distributor/manufacturer.
Good luck!
