Unable to see multiple monitors

[edavies]

So... I just finished my Sierra install (10.12.2). Phew! I have multiple monitors but only the one (DVI) actually lights up. The HDMI plugged into my graphics card does not. Neither does the VGA monitor attached to my mobo. The NVIDIA Web Driver refuses to stay toggled in spite of following all the directions I could find...

I've been through all the help below. Any and all help would be appreciated! Can anyone help me solve this?

Update: By adding "nv_disable=1" to boot args, I was able to resolve the issue. The system now boots with NVIDIA web drivers (finally), but still unable to see second or third monitor.

Update: My computer seems to think there is a projector attached to the system. Not sure what to make of it. The second monitor plugged into the graphics card still not being recognized...

You might review the AGDPFix threads to determine if you might need it. I know it's needed for some configs (some SMBIOSes) to enable >1 monitor.

I don't see the Nvidia logo on your bar, so you may not have the Nvidia Web drivers installed (or they don't load because of nv_disable=1, which I don't think is needed).

After you install the NvidiaWeb drivers, you also have to check NvidiaWeb in your clover config.

If your drivers don't stick, you may have problem 6 described here:

With terminal you can check your NVRAM.
Type "nvram -p", you will see a list of values, nvda_drv=1 should be there.

This is Chinese to me. Can you elaborate?

I just disabled the button. That's all. I did add "nv_disable=1" to my config and that's when the web driver setting finally stuck. Is that what's keeping my 2nd monitor from working?

I'll get back with you once I've had a chance to look at this.

Note that nvda_drv=1 is no longer valid in 10.12 use Nvidia Web. Attach config.

Yeah. I tried "nvda_drv=1" without success. Once I tried "nv_disable=1" my computer finally booted with NVidia Web Driver as the default, but that may be why it's not fully working also...

You had nv_disable=1 under boot args. Also (inject intel) noticed that you had CsrActiveConfig set to 0x3 should be 0x67 to avoid booting problems. Try the config i provided.

TYVM... testing now... what does CsrActiveConfig do?

CsrActiveConfig is to disable SIP. Having SIP partially disabled causes issues with booting hangs at OsxAptioFix or OsxAptioFixDrv2 hence why i recommend that its set to 0x67 to avoid issues with booting.
