Screen remains black after installation.

Recommended Posts

Hello everybody

Have Mojave successfully installed without any error. But I can only start Mojave with nv_disable = 1.

If I start without nv_disable the screen will remain black.

The same thing happens with all versions after Mavericks.

The PC has an HDMI In / Out connection.

About the HDMI connection Works everything. The graphics card is recognized correctly. The graphics acceleration works wonderfully. But the built-in Minitor stays black.


I have a fully functioning Mavericks. I can not update it. When I update the same thing happens as above.



My PC is an AIO Lenovo B540P


Intel Core i5-3350P Ivy Bridge-DT

Board: LENOVO MAHOBAY

Chipset: Intel H77 (Panther Point Base)

NVIDIA GeForce GT 650M GK107M / N13P-GT (Kepler) Usually it does not need a driver. Is the same as Imac 13.1 only with 2GB of RAM


This is the HDMI In OUT port of Lenovo

That's on my TV via HDMI Out.

I can not get any further.

I think the problem is due to the HDMI Out.

I have to direct it to the internal connection but unfortunately I do not know how?


I do not have that much knowledge about OSX.

Yes and no. Both work. With nv_disable I see picture but the resolutions are wrong and the graphics acceleration is not available.

Like here in the picture.

The system loads the correct drivers, but somehow does not recognize the internal monitor connection.


I have to find out where in the OSX system this is. Or I have in the OSX system HDMI Out disable and redirect it.

This is not possible in the Config.plist
