GPU: iGPU Intel HD4600
Monitors: 1x24inch @ 1920x1080 on DVI / 1x29'' Wide @2560x1080 on HDMI

Note: At this point, the Dual screen not working yet !

Customize plist
I added this to my org.chamelon.Boot.plist to enable resolution 2560x1080

<key>IGPlatformID</key>
    <string>0c260000</string>

Result

All work perfect except monitors:
- No dual screen with this configuration (whatever the resolution).
- At startup or waking from sleep, the Monitor (29'' wide) does not calibrate on the right output (Defaut DVI). I have every time Please select the correct output (HDMI).

Any help is welcome! Thank you all in advance !
(And excuse my poor english)

Why did you choose a laptop framebuffer?

Why did you choose a laptop framebuffer?

I've find this code on this forum. And without theses 2 lines, i can't run my comp at 2560x1080.

Have you an alternative ?

Have you an alternative ?

See New Intel HD Graphics Boot Flags in Chimera - tonymacx86.com
Use HD4600 default, 3 DP connectors. Edits available for HDMI and DVI. 1080p/1440p supported; HDMI wide unlikely without SwitchRes.

Curiously, the alternate 0D220003 seems to works for user with HDMI + DVI, but not for me...

Now i've the same issue with any flag:

Clearly there is an issue with DVI. Attach an IOReg for each case.
