Question / Help Adding a Third Monitor/Optimal settings

[SPACEPISTOL]

I have my laptop on the left, an ASUS VE228H in the middle (set as the main display) connected via HDMI, and an HP w1907 on the right connected via mini displayport (through an active VGA to mini DP). OBS Studio labels the ASUS "display 0" and the laptop monitor as "display 1" but will not see "display 2" the HP. Any suggestions?

Also, while I am here, I figured I would ask for some setup help to get the best quality stream.
I just updated to OBS 0.15.0 (64bit, windows)

Board: Alienware M14xR2 A14

CPU: 2.40 gigahertz Intel Core i7-3630QM

Display: Intel(R) HD Graphics 4000

NVIDIA GeForce GT 650M​

Drives: SAMSUNG SSD PM830 mSATA 64GB (OS)

WDC WD7500BPKT-75PK4T0 (other)​

RAM: 16GB Dual Channel DDR (2 x 8GB)

Thank you so much!

Hmmm... interesting issue. Close OBS, setup your monitors, then open OBS and see if you can the monitor. If not, close OBS and make the HP the primary monitor. Then Open OBS and see if you can add it as a source.

If that doesn't work, then something might be blocking OBS from recording/using the HP monitor.

Interestingly enough, when I switched the HP to the main monitor, OBS Studio couldn't see the other two monitors. Is it possible the Mini DP is being run by the Intel card and the other two are being run by the NVIDIA card? Sorry, I don't really know a whole lot of specifics about computers, though I wish I did, I can just operate them, relatively well haha

Logs shows a monitor running on a different GPU. Looks like DisplayPort runs on a different GPU on your laptop.

I have the same problem with 4 monitors, 2 on each GPU. Using AMD Radeon HD 7350 and Intel HD graphics 2000. OBS-Studio in Direct3D mode can only see 2 of my monitors on primary GPU, on windows 10.

Making all monitor use the same GPU may fix this, but many GPU, including both of mine, don't support more then 2 simultaneous outputs.

Switching OBS-Studio to Opengl does appear to allow capturing all monitors, but at a speed cost.

Hm.. I have no idea how to even test that.

Well, if I don't use my HP monitor, what would be my most optimal setup?

sam686: You should be able to hook up 3 monitors to your GPU: https://answers.yahoo.com/question/index?qid=20120229212505AAWznhF

SPACEPISTOL: I would say that the most optimal would be to hook up the monitors you want to use with OBS so that OBS can see them. Then put whatever isn't OBS/the game/the window/the monitor you want to capture on the 3rd monitor... or reduce your setup to 2 monitors.
