It turns out the USBs not showing up was an issue related to having already a pre compiled SSDT, after doing everything from scratch all works fine. I can even get ethernet from WD15 and DA300 docks from Dell. Also hotplug works fine. Many thanks.

 

The UltraWide monitor is still not working. I tried with -cdfon but no luck. I saw I have enable-hdmi20 with value (01000000) tried -cdfon with and without that property and still no correct resolution. Again this is connected directly to the notebook, no docks or adapters.

Thanks.

 

Unfortunately it didn't worked. I guess next step is what you mentioned.

 

A quick search showed this post from you a while back.

 

Is this up to date or you recommend something else?

 

Also, you think latest Hirens with WinPE would be ok to run this guide?

Hmm, I don't see it as a listed value on the screen shot

just run setup_var 0x795 to see it's current value

Then run setup_var 0x795 0x4

That way you can always set it back if it's not working. Also setting BIOS to load Default will reset it back to the old value as well.
