mgaffar Posted April 16, 2013 Share Posted April 16, 2013 Hey guys, I have an alienware m14xr2 with a 1366x768 lcd and an intelhd4000. I had the intel hd4000 working perfectly with the the 1366x768 original lcd that came with the laptop. I wanted to upgrade my screen to a 900P screen (1600x900). I checked both my OSX and Win7 partitions before installing the lcd and they both loaded fine. I installed the lcd into the laptop and booted into windows 7 to verify it worked fine before putting the laptop together. I verified the resolution also and windows 7 was using 1600x900. Then i tried to boot into OSX (10.8.3) and it went to the chameleon screen, then apple screen popped up. After the pinwheel stopped spinning the screen flickered and went blank. I know the system is booted because i can hear the volume changer dinging. I have also tried all the efi strings for the intel hd4000 by creating copies of my chameleon.boot.plist file and loading it through boot flags when i launch my osx system. Does anyone have any ideas as to why this is happening? I also cant boot into safe mode, the screen is still blank. I was thinking of removing the intelhd4000 kexts but was looking for any other suggestions before doing that. Thanks in advance, These are the strings i tried. ig-platform-id: 01660000, Stolen RAM for FB: 96MB, Pipes: 3, Ports: 4, FBMem: 3 Code: <key>device-properties</key> <string>7f0000000100000001000000730000000200000002010c00d041030a000000000101060000027fff04002c0000004100410050004c002c00690067002d0070006c006100740066006f0072006d002d006900640000000800000000006601140000006800640061002d0067006600780000000d0000006f6e626f6172642d31</string> ig-platform-id: 01660001, Stolen RAM for FB: 96MB, Pipes: 3, Ports: 4, FBMem: 3 Code: <key>device-properties</key> <string>7f0000000100000001000000730000000200000002010c00d041030a000000000101060000027fff04002c0000004100410050004c002c00690067002d0070006c006100740066006f0072006d002d006900640000000800000001006601140000006800640061002d0067006600780000000d0000006f6e626f6172642d31</string> ig-platform-id: 01660002, Stolen RAM for FB: 64MB, Pipes: 3, Ports: 1, FBMem: 1 Code: <key>device-properties</key> <string>7f0000000100000001000000730000000200000002010c00d041030a000000000101060000027fff04002c0000004100410050004c002c00690067002d0070006c006100740066006f0072006d002d006900640000000800000002006601140000006800640061002d0067006600780000000d0000006f6e626f6172642d31</string> ig-platform-id: 01660003, Stolen RAM for FB: 64MB, Pipes: 2, Ports: 2, FBMem: 2 Code: <key>device-properties</key> <string>7f0000000100000001000000730000000200000002010c00d041030a000000000101060000027fff04002c0000004100410050004c002c00690067002d0070006c006100740066006f0072006d002d006900640000000800000003006601140000006800640061002d0067006600780000000d0000006f6e626f6172642d31</string> ig-platform-id: 01660004, Stolen RAM for FB: 32MB, Pipes: 3, Ports: 1, FBMem: 1 Code: <key>device-properties</key> <string>7f0000000100000001000000730000000200000002010c00d041030a000000000101060000027fff04002c0000004100410050004c002c00690067002d0070006c006100740066006f0072006d002d006900640000000800000004006601140000006800640061002d0067006600780000000d0000006f6e626f6172642d31</string> ig-platform-id: 01660008, Stolen RAM for FB: 64MB, Pipes: 3, Ports: 3, FBMem: 3 Code: <key>device-properties</key> <string>7f0000000100000001000000730000000200000002010c00d041030a000000000101060000027fff04002c0000004100410050004c002c00690067002d0070006c006100740066006f0072006d002d006900640000000800000008006601140000006800640061002d0067006600780000000d0000006f6e626f6172642d31</string> ig-platform-id: 01660009, Stolen RAM for FB: 64MB, Pipes: 3, Ports: 3, FBMem: 3 Code: <key>device-properties</key> <string>7f0000000100000001000000730000000200000002010c00d041030a000000000101060000027fff04002c0000004100410050004c002c00690067002d0070006c006100740066006f0072006d002d006900640000000800000009006601140000006800640061002d0067006600780000000d0000006f6e626f6172642d31</string> ig-platform-id: 0166000A, Stolen RAM for FB: 32MB, Pipes: 2, Ports: 3, FBMem: 2 Code: <key>device-properties</key> <string>7f0000000100000001000000730000000200000002010c00d041030a000000000101060000027fff04002c0000004100410050004c002c00690067002d0070006c006100740066006f0072006d002d00690064000000080000000a006601140000006800640061002d0067006600780000000d0000006f6e626f6172642d31</string> ig-platform-id: 0166000B, Stolen RAM for FB: 32MB, Pipes: 2, Ports: 3, FBMem: 2 Code: <key>device-properties</key> <string>7f0000000100000001000000730000000200000002010c00d041030a000000000101060000027fff04002c0000004100410050004c002c00690067002d0070006c006100740066006f0072006d002d00690064000000080000000b006601140000006800640061002d0067006600780000000d0000006f6e626f6172642d31</string> Link to comment https://www.insanelymac.com/forum/topic/287931-intel-hd4000-stopped-displaying/ Share on other sites More sharing options...
