Brother I don't know what point you're trying to make, I don't understand what you mean by upscaling in this context and what some internal format conversion is meant to accomplish or why one would want that. What does internally converting 4k @ 240 to 8k @ 60 accomplish that just outputting 8k @ 60 directly from the computer wouldn't accomplish?
