Two Nvidia GPUs, stop games from using the 2nd one?

JoeCoke · April 12, 2023

Heya, I have a GTX 1070 and a GT 1030 in my PC so I can have my four monitors on my desk and my TV all hooked up at once, while still having my 1070's HDMI port open for my VR headset. It's working great, except for the fact that a lot of games keep wanting to use the GT 1030 and not the 1070...

My nvidia control panel has an option to select which GPU to use for OpenGL, but no option for DX. I saw a thread mention that you can select a preferred GPU in program settings, but no such option is there for me.

I'd also like to mention that it's acting really weird about letting my change resolutions, it's either blank or greyed out.

This is a recent change as I used to use my 2600k's integrated graphics to add my other displays, but I want to stop doing that because Windows won't let me duplicate a nvidia display to an intel one, meanwhile I can duplicate my main monitor hooked to my 1070 to my TV which is hooked to my 1030 and it works great. I really want this to work. Am I SOL or is there something I'm missing? Thank you very much for taking the time to read this.

PS: FUCK THE NVIDIA CONTROL PANEL

Okay so wait, I'm dumb, I've made a finding. It's because I'm duplicating my main monitor to my TV, but my TV is being treated as the main monitor, which is on the 1030. Undoing the duplication fixed the problem. So.... I guess I'll keep messing around with it to see if I can get the duplication to treat the monitor as the main display and not the TV. (I can't believe I didn't think of this before going to the trouble of making a post, oof.)

EDIT:

So I'm just gonna rework things to where my TV and main display are on the GPU, screw all this LOL. It always wants to treat the 1030 as king when duplicating displays across both GPUs.
