Hey There!

 

I`ve managed to install a dual boot with Mavericks and Win7 on my Lenovo T420 following the instructions from the T420 guide in this forum. Everythings works fine except the external monitor. Styrian told me, that I should ask in this forum.

 

The problem:

Mavericks is not working with an external Monitor. In Win7 everything works fine, so its not a hardware defect. If i disable the NVIDIA and use just the onboard Intel HD 3000, its the same problem. I connect via VGA
I connect the Monitor before startup but only get a black screen and no entry für a monitor in the system preferences. The NVIDIA is showed in the system profiler.

With an old TFT Monitor form my work it works (but if I change the resolution its black again), but all other monitors i tried didn`t work.

 

I have attached the config.plist, but its the original from the guide in the forum.

 

Because I have to do a lot of graphic stuff ,its essential for me to use an external monitor.

 

Someone has a hint? Do you need more specs?

 

Greeting

Niklas

Hello!

 

Please upload a private made DarwinDumper archive, switched to integrated gfx only. Then try  to boot with gfx set to discrete. To be able to boot add on clover bootscreen temporary the boot argument: nv_disable=1, and get an other DD report with this setting.

 

Have fun.

Hello!

 

I have looked in your reports. What I have noticed, there are tow devices IGPU in your DSDT (also in the package of tluck). I don´t know, where this is coming from. Under device PEG should be in any case an other named gfx-device concerning your NVDA. No wonder, that the card is not recognized.

 

Assuming that you are using an already patched DSDT.aml, I have removed some things from ACPI in your config.plist. Config.plist is attached.

 

If you want to try it, you should create a clover trial usbstick ( some hundred mb should be enough for this), install clover on it, copy your current Clover to it and replace the config plist with the attache one. I hope, that everything, that has worked before is working again.

 

Can you please upload your original ACPI tables extracted with clover:

 

1. Gfx set to integrated

 

2. Gfx set to discrete

 

3. Gfx set to Optimus

 

Have fun.
