How to visit VRAM? hook the display content

Hi, all:

I wanna do one app, that can control the display content, all of it, including whole window desktop.

so i think if i can visit VRAM, like a buffer, maybe I can modify it before it’s submitted to monitor

is there any way to do it, in CUDA ?

Thanks

No. The raw flat device memory is not directly accessible by CUDA apps, likely for both stability and security reasons.
