Black Screen with High Sierra and HDMI Output

Hi everybody!

​

I've just installed High Sierra in my computer but there are some issues with graphics output. My GPU is an ASUS GTX750 (Maxwell) and Nvidia Web Drivers are required to have graphics acceleration. The installing procedure was simple, with no problems and setting the proper configuration (Lilu, WhateverGreen Kexts, NVRAM fully working, NvidiaWeb in System Parameters, etc.).

​

However, the behaviour is a little bit strange, because if I use my main monitor (LG UltraWide 29'' with HDMI output), I get no signal in the moment when the Apple logo should appear. Nevetheless, my old monitor (VGA) works perfectly with the same configuration and the drivers correctly detected.

​

I want to know if somebody has the same problem as mine and if there's a solution to this problem. As I could read in some other sites, High Sierra drivers have some problems with this kind of outputs, but I would like some more feedback about this topic. If you require more details about my configuration, HW or related, you could ask me.

​

Thanks for your help!
