I'm actually surprised there hasn't been a dedicated effort to support display offload to, say, the CPU's iGPU.

I'm sure manufacturers would love saving a dollar per card, and OEMs would appreciate eliminating the support calls from "I just bought a new $2500 gaming PC and no video" because they plugged the monitor into the iGPU instead of dGPU.

This is exactly what "Optimus" and "hybrid graphics" is, the issue is that you need to configure that - laptops will provide information to OS "hey, this card has no video output" or "hey, there's an output MUX connected to output X on iGPU and output Y on dGPU", and drivers pick that up and know they have to setup transferring frames between the two or trigger the mux etc.

nVidia has also used the datacenter cards to run GeForce Now, at least for some lines of the cards, plus some of them come with license (or you can buy it extra?) for nVidia GRID that provides more flexibility for multi-instancing etc to run in virtual desktop

I have occasionally wondered the same thing.

Thinking about it more, on my setup I have a DVI port on the motherboard that I would be happy to use with a DVI cable, but I instead need to buy a DisplayPort <-> DVI converter cable to plug directly into my video card...

Yeah, seems like an obvious thing for some motherboard providers to want to provide.
