[SOLVED] Black screen with Dual Monitor connected

[debba]

I know that only one hdmi port works in your GPU.
In the config.plist you have to set video port to 5 because your GPU have five port.
I setted 3 because my Gtx is the version with 1 hdmi 1 dp and 1 dvi

I've seen that you solved the problem with gtx 1050ti (3 ports) with config.plist as you posted.
I own the same video card but I just can't boot with both monitors (1 in hdmi and another in DP) and I'm forced to plug the second monitor until after first starting (that's work, but uncomfortable).
I tried with your configuration and enabling "Inject Nvidia" but the problem persists.
May I ask you how you set the smbios?

Thanks

Good news! My Gigabyte GeForce GTX 1050 Ti 4095 MB works perfectly with dual monitor at boot!
I had to set my config.plist in this way to enable both monitor :

</dict>
<key>Graphics</key>
<dict>
<key>BootDisplay</key>
<integer>1</integer>
<key>DualLink</key>
<integer>1</integer>
<key>Inject</key>
<dict>
<key>ATI</key>
<false/>
<key>Intel</key>
<false/>
<key>NVidia</key>
<true/>
</dict>
<key>NvidiaSingle</key>
<false/>
<key>VRAM</key>
<integer>4095</integer>
<key>VideoPorts</key>
<integer>3</integer>
</dict>

Initially did not work because I leave Inject/Nvidia/False.
Strangely I had to set Inject/Nvidia/True I don't know why! Now my hackintosh works so good!
Thanks to MacPack and Asgalor for the support without you I would not have been succesful.

Thanks for your post, it is working with my gtx 950 too. thanks a lot.

This works on my build. 1080Ti on High Sierra with Driver 378.10.10.10.15.114

All of them are working at the same time?
Can you use mobo video out too?

I think that only one hdmi port works with display port toghether no more, like my hackintosh setting.

Ok so, today I got on a 1050 (2gb version) hdmi and displayport working together, both on at boot. Hdmi seems to be the first booting screen for bios and clover.
Did you try to have dvi working too? 3 monitor system

I have never tried with dvi. I’m sorry...

Thanks riccardo.uccelli your guide helped me too. I ignored dual link as I don't use that and I changed BootDisplay to 2. My Acer 4k monitor would not switch on after the initial boot process. My other monitor would stay black if both were on. However before your tip one monitor my Dell would work fine in the boot process all the way to using the Mac. If I set the BootDisplay to 1 the Acer would not work. My Acer is on the DisplayPort and my dell is on HDMI. I was almost tempted to revert back to my old setup of my internal Graphic card Intel P4600 which had it's issues but did power both monitors on boot to mac.

After a few hours of hacking the config here's what worked for me:

Graphics card: GIGABYTE GeForce GTX 1050 Ti Windforce OC 4GB
Driver: 387.10.10.10.30.103 macOS 10.13.4 High Sierra (17E199)
OS: High Sierra 10.13.4 (17E199)

    <key>Graphics</key>
    <dict>
        <key>BootDisplay</key>
        <integer>2</integer>
        <key>DualLink</key>
        <integer>1</integer>
        <key>Inject</key>
        <dict>
            <key>ATI</key>
            <false/>
            <key>Intel</key>
            <false/>
            <key>NVidia</key>
            <false/>
        </dict>
        <key>NvidiaGeneric</key>
        <false/>
        <key>NvidiaSingle</key>
        <false/>
        <key>VRAM</key>
        <integer>4095</integer>
        <key>VideoPorts</key>
        <integer>2</integer>
    </dict>

I use 2 monitors, one monitor plugged into 1st HDMI port and second into the DP port. The graphics card had 3 HDMI ports but only the first one works.

If you think it's because I've set VideoPorts to 2, is not, I've set it to various numbers and only the above combination seems to work.

Hi. Can someone advise how actually do this. I'm a total noob.

I have a gtx 750 Asus card and I can only get VGA working. Trying not to spend money on another card as the VGA is perfect but I need dual monitor so I also need one of the hdmi or DVI to work along side
