There is no mirroring or extending when using an external monitor.

Only one display device is recognized, either the laptop LCD or an external Thunderbolt monitor.

This physically damages the screen as time goes (doesn't take long, several weeks will do).Ī Thunderbolt external display can be used if the laptop lid is shut at the boot time (before image showing up on the laptop LCD).

When the laptop LCD is used, it stays on full brightness and does not turn off when the lid is closed. The internal LCD is treated as an external monitor, with only one possible resolution: the maximum display resolution (1440x900 or 1680x1050). The defects are present at the boot time. However there is no graphic acceleration.Įxisting or new graphics defects(blue or pink bars/lines, jagged/out-of-order image, noise, etc.) will show up as temperature fluctuates (running GPU at high temp, power on/off, etc.), presumably due to the lead-free solder problem.

The black screen (no display) problem is usually fixed.

I can't change the brightness of the screen, the color calibration is different. $ mv /Library/Extensions/AMD* /DisabledExtensions/Īfter that the Mac boot up in Mavericks but I have no graphic acceleration whatsoever, every animation is very slow. I have been able to access the system by running these commands in "Single User Mode": $ mkdir /DisabledExtensions Hopefully waiting for an Apple replacement program I want to disable the discrete graphics and enable only the Intel HD3000 chip in the i7. I have an early 2011 MacBook Pro that is affected by the well known problem on the graphics card (AMD 6490M 256MB).
