If so, I wonder, perhaps its possible to emulate that scaling feature in hardware by writing a pixel shader operation that can sample each pixel and duplicate it to the surrounding pixels to enlarge the image....
....Because, ya know, the Prevail's Adreno 200 GPU has shader capability.
No, that part likely comes from the video scaler built in to the video controller. MHL gives a direct mirror off of that path.
I've got full schematics for one of my MHL phones, I can go verify that.
Just wanted to point out that you're going to have to do a lot in software to get there from here.
