Question / Help OBS Studio on Laptop, dual graphic card problem

[hBaleine]

Hello,

I am new to streaming. But i have read a lot about it!

Let's begin with my spec : I play on a laptop and i want to stream with it too. Without buying anything else.
GPU : 970M 3GB DDR5
Proc: i7 6700HQ with intel HD graphics 530
16GB ram DDR4
With windows 10 64bits.

So here is my problem :
I use OBS studio 64bits. In the Nvidia pannel of my computer, I can choose wich GPU can lauch the program(OBS).
Whenever i put it on my 970M i can stream my game capture with no problem, but i only got a black screen when i try to stream my screen capture.
On the other side when i configure OBS to the default setting (with the integrated HD530 gpu) i can no longer stream my game capture. I only have a black screen. But i can stream my screen capture.

I could stream my games with a screen capture if I put them on borderless but then i have very bad streaming performance.

Do you guys have any idea what i could do to stream both my game capture and screen capture without going to NVIDIA pannel each time?

Thank you very much for your time.

You don't have a choice. There's nothing you can do. It's a restriction caused by the switchable graphics laptops.

@Harold is correct that integrated HD530 gpu is your pain. Although OBS might not give you the correct options here you could use another app to do this potentially like xsplit or shadowplay. Worth ago if you can't live with it but they might not give you the options OBS can provide for a custom look etc.

Thank you a lot for your answers.

I might give up on the screen capture then. I don't really like xsplit or shadowplay.

Could i use any external device (capture card, or another computer) to capture everything fine on my laptop then? and bypass the problem?

 

[Beardedbob]

A two pc setup would give you some options for capturing the laptops output which could then be feed into OBS and manipulated / re streamed say.

I had the same issue, where my gaming laptop was forcing one monitor to run from the CPU Intel card and the second monitor from the GPU Nvidia card. Fixed it. Easy solution (given below). Depending on what you're trying to do, it may or may not help you... in my case, I am mainly interested in capturing Roll20 for streaming D&D games, but it can also work for other projects.

Don't try to Display Capture your second monitor. Instead, do a Window Capture of anything you're trying to grab, from either monitor. OBS will pull it all together. Enjoy.

If your PC has more than one display adapter then disable the unused adapters in Device Manager. OBS doesn't seem to know the active one so if you narrow it down to only one choice it works.

 

[Harold]

That's not how you solve the problem.

 

[DiggFerkel]

Well, it's quick, simple and it works. So yes, that's how you solve the problem until the programmers fix the code.

Following the laptop troubleshooting guide we have is also quick and won't break core components of how your system works.

I've tried doing that, but it slowed my whole pc and used 80% of CPU. What solution are you mentioning Harold?

Hello everyone. You can try the OBS 27 RC1. It fixed the problem of the dual GPU. I already tried it in my laptop.
