 Hi,

I have installed 10.10.0 Yosemite to my Sony VAIO E Series VPCEH25EN
Boot flags used -v dart=0 -f

After installation, I have installed the 10.10.5 Combo Update.
After reboot I have installed some kexts, Basic Boot Options, Chimera bootloader, SMBIOS into my Yosemite SSD.

 

FYI, Full Graphics and native resolution along with Graphics Chipset detected was present at the first boot. I didn't have to add any kexts.

Boot time has reduced. I have full Graphics, native resolution, App store access. 
The only thing I want to work is HDMI. 
No HDMI output, I have tried my AOC monitor and Sony Bravia TV. Not working.

Before I play around with tools, I wanted an expert opinion on what should I try.
Graphics chip is NVIDIA GeForce 410M 512 MB.

I have tried booting with GraphicsEnabler=Yes/No . No change.

Should I try Nvidia Web Driver?

 

And what is EDID Injection? Is it necessary for HDMI to work?
