我可以强制监视器使用批处理/ C ++切换输入

Question

I have 2 graphics cards (an integrated Intel card, and an NVIDIA card), and both of them are connected to a single monitor (VGA / HDMI).

say somehow both of them have different outputs (I have a windows 7 and a VM, each of which is using one card).

Is there any command/API that I can send to the monitor so it can automatically switch its input from VGA to HDMI or the other way around?

Answer 1

No — there is no publicly documented, standard way of doing this.

(It's possible that some rare monitors may provide a way of doing this. I've never seen or heard of one, though, and it'd be proprietary to that monitor.)

Answer 2

There are several tools that support this via DDC commands.
