Greetings! 

E6420-i7 2640m-Nvs4200M

Using this guide (https://osxlatitude.com/index.php?/topic/8506-dell-latitude-inspiron-el-capitan-clover-guide/&do=findComment&comment=54621)combined with the specific DSDT for the gpu,  my new monkey is running extremely well, great performance after i generated a specific SSDT+Jakes DSDT (  E6420_Nvs4200M = E6420 + zip.gif  DSDT.aml.zip), however with Optimus Enabled, it will not output to HDMI and it is my understanding that it won't be possible.  With Optimus disabled,I have tried Jake's "DSDT-NVS.aml" (https://osxlatitude.com/index.php?/topic/7478-dell-latitude-e6xxxe7xxx-yosemite-install-guide/) as well as Wern's (http://www.insanelymac.com/forum/files/file/342-latitude-e6420-nvs-4200-dsdtaml/?st=10#commentsStart) but both hold at GeForce Sensors, then render a black screen.  Any assistance would be most appreciated. Thanks very much!

Sorry Jake, still no USB or HDMI Video. The HDMI monitor powers on when the system boots, however the message "monitor is going to sleep" flashes every 10 seconds. I'm using the last config. and Wern's DSDT. Please see attached.  Optimus is not checked in the bios. Bios version A22.  Thanks for your efforts.
