HD4000 - i3 3225 - GA-Z77-DS3H - Dual Monitor Question

[johannvonperfect]

Relevant Setup:
i3 3225
Z77-DS3H
8 GB 1600 MHz RAM
No video card

My apologies if this question has been asked and answered: I have tried a search and while there is a wealth of information out there I did not see anything that directly and succinctly addressed my specific issue.

I recently downgraded from a i5-2500k/Z68MA-D2H-B3 setup to an i3-3225/Z77-DS3H setup. I have one monitor (on the left in the attached pictures) connected to the motherboard by DVI. The monitor on the right is connected to the HDMI port, albeit with an HDMI cable coming from the board to an adapter to connect to the monitor by DVI. I am trying to get the HD4000 graphics to correctly display on both monitors.

After getting the CPU and motherboard, I did a fresh install of Mountain Lion 10.8.3. I then ran Multibeast with the typical settings I have seen: No DSDT, typical Audio/Network settings, 1080p display (although my monitors are technically 1680 x 1050, which I later changed in the org.chameleon.Boot.plist). For BIOS settings, I followed some of the various guides for my board, with the change of InitDisplay to IGFX as opposed to Auto, and setting Internal Graphics to Enabled. I left the memory settings the way they were: 64MB.

When I boot up now, the display connected by HDMI cable and HDMI/DVI adapter displays clearly through the BIOS screen, clearly through the Chameleon loader, and clear through the Apple logo. When the computer gives me a chance to log in, however, the screen gets garbled as noted in the attached low tech screen shots.

Booting with GraphicsEnabler=No results in clear pictures on both monitors, but they are mirrored and cannot be changed to be distinct workspaces. I also tried setting system definitions to MacMini 6,1 with no success.

The fact that it looks normal during BIOS and Apple logo, as well as with GraphicsEnabler=No, leads me to believe it is not a hardware problem or a problem with the cables. I am guessing it is a setting I have missed somewhere along the line.

Any help or other thoughts would be appreciated.

I have a similar problem.

My setup is:
GA-Z77X-UD5H
i7 3.5K
OS 10.8.3
Monitor 1 DVI: 1920x1200
Monitor 2 DVI: 1920x1200

Everything works fine. The first monitor is connected to the DVI port and the second monitor is connected to the HDMI port with a HDMI-to-DVI cable. Both monitors are identical.

The problem is I don't get video on the second monitor. Even tough the Display panel (on the system preferences) does recognize the second monitor.

Any ideas?

Your situation sounds slightly different than mine for a couple of reasons. 1) You have a different motherboard and processor (probably not a big difference there though as we're both trying to use HD4000 graphics). 2) I get video from the second monitor - it is just garbled (though I also have the problem that the Display system preference does not recognize it).

Anybody else out there have either no video, or garbled video through the HDMI port?

I know this thread is sort of old, but I have the same motherboard as the OP with the same dual monitor issue. Did you guys figure out how to get it to work? Thanks.

 

[johannvonperfect]

I still have the same problem. I also posted over in the Installation forum:
http://www.tonymacx86.com/mountain-...77-ds3h-rev-1-1-only-one-monitor-working.html

No real leads there either. I have since tried various graphics string injections, SMBIOS for iMac, Mac mini, etc. with no success.

The thing I don't get is, there seem to have been problems with this board/CPU combo, but I have never had any of those problems (system won't install/start, etc.) And nobody else seems to have my specific problem (except you cmedlin). At least I'm not crazy haha.

Well, I will let you know if I figure something out. I know it is not hardware related, because a while ago after I built my system I was using a DSDT for HDMI audio using a HDTV as the main monitor and could get an extended display by hooking up a DVI monitor (I think that was with 10.8.1).

But, since then I have re-installed without a DSDT and updated to 10.8.4 and have the problem with the HDMI display being all scrambled. Maybe I need to go back to a DSDT to get it working... since I do not need hdmi audio right now I was hoping to avoid that but perhaps that is the answer?

Johannvonperfect, here is an update for you. I got it to work finally, hopefully this will work for you as well.

Even though it says this thread is closed and that the current versions of chimera/chameleon make it unnecessary this is the only thing that worked: http://www.tonymacx86.com/mountain-...ad-fyi-only-guide-10-8-how-enable-hd4000.html

So basically I deleted any prior hd4000 graphics injection:

<key>GraphicsEnabler</key>
<string>yes</string>
<key>Graphics Mode</key>
<string>1920x1080x32</string>

and added the ig-platform-id: 01620005 to my org.chameleon.Boot.plist:

<key>device-properties</key>
<string>7f0000000100000001000000730000000200000002010c00d041030a000000000101060000027fff04002c0000004100410050004c002c00690067002d0070006c006100740066006f0072006d002d006900640000000800000005006201140000006800640061002d0067006600780000000d0000006f6e626f6172642d31</string>

Now I have the DVI port running my main display and HDMI -> DVI running my secondary, extended display. Hope that helps.

I had previously attempted injecting each of the ig-platform-id options including 01620005. I tried with GraphicsEnabler=Yes and GraphicsEnabler=No, but neither helped. I have now also tried completely removing the GraphicsEnabler string - it did not resolve my issue.

I have also taken steps to create a DSDT based on the information at this link:
http://www.tonymacx86.com/dsdt/83565-native-dsdt-aml-ide-compiler-maciasl-open-beta.html

As well as the repositories by Pjalm:
http://www.tonymacx86.com/dsdt/89727-maciasl-patch-repository-thread.html#post561052

Running Multibeast with the fresh DSDT did not help. I wonder if I should just start from scratch with a fresh Unibeast install and see what happens. I'm guessing with the various things I have tried there could be extraneous patched kexts and what not floating around.

Glad you were able to resolve your issue though.

Hello,

I have a similar problem.. On boot the HDMI freezes on Apple loading wheel, while DVI works just fine.

Did anyone manage to find a solution or have any suggestions please?

Thanks,

Damien

Had exactly the same problem. Found a working solution; forget about the AVI connection- OS X doesn't seem to like it. Use the HDMI connection (cable or adapter to whatever you need) for one monitor and the DVI connection for the other one.
