Just to be sure... is your Monitor connected to the DVI or HDMI port ?

It's good to know I'm not the only one. I'm using my DVI port, and my current ML install with 10.8.5 boots perfectly. I've seen in a thread from 2012 that we need to place the current nvidia drivers (or, I assume, the working drivers from mountain lion?) in Systems/Library/Extensions in our unibeast drive, but I can not see these folders on the drive. All I see is the install OSX mountain lion app.
 
Got it working now. I've used ONLY these Bootflags:

GraphicsEnabler=Yes, PCIRootUID=1
 
I had the same problem, solved by:

GraphicsEnabler=Yes Mode=2560x1440x32

Apparently you have to tell it the native resolution.
 
I will try those suggestions tonight and see how I fare.

This worked for my motherboard GA-H61M-DS2H....I was able to see the screen to install Mavericks on the hard drive.
 
This worked for me on P55M-UD2 and Geforce 9800 GTX

GraphicsEnabler=Yes -v -x

Make sure DSDT is in the extra folder on the Unibest USB stick. I also moved the "org.chameleon.boot.plist" and "smbios.plist" from my extra folder on ML to the extra folder on the USB stick.

Hope this helps!
 
i use GraphicsEnabler=Yes Mode=1920x1080x32 to solve the disable of the monitor

my configuration:
Asus sabertooth x58 with i7 920
nvidia gtx 260 (gainward golden sample)
lg fullhd monitor connected with DVI
 
Desktop
Other |  i7 Other |  GeForce GTX 770
The same here, at installing 10.9 Mavericks from unibeast USB. Very common problem, as i see.
MB: Gigabyte EP35-DS3R
VIDEO: Asus GeForce 8800 GTS 512mb (was OOB everytime)

I tried almost all key combinations, and even custom NVDANV50hal - nothing works.
Everytime after the moment the display losts signal - desktop continues to work, maybe even loads to install screen. I can't see it. And one more - after reset, in 100% of cases MB BIOS crashes (with the reset of settings and with error message).

Hope it helps.

Update: if it's allowed — i can share a link to some insane mac forum, where guys are talking about removing all nvidia drivers from usb to achieve installation screen. Maybe, this will work, but i don't know how to make it. Can you help?

Update 2: SOLVED!
GraphicsEnabler=Yes PCIRootUID=1 Mode=1680x1050x32 (native resolution of display)
