I did some interesting test on MSI U270 netbook (E-450 APU) + EH-TW3200 projector (connected via HDMI). There is menu item "HDMI Video Range" with options:
- Auto
- Normal
- Expanded
manual says:
"If this is set to Auto and a blackout/whiteout condition occurs, set the video range of the projector to match that of the DVD player. The setting on the DVD player can be either Normal or Expand. Note that if the equipment's DVI port is connected to the projector's [HDMI1] / [HDMI2] input port, Auto is not displayed."

On fglrx driver + XBMC xvba Frodo there are all three options in menu "HDMI Video Range". But on OSS driver + XBMC Gotham there is no "Auto" option.
I made four photos with different settings in the menu. The camera was in manual mode - exposure parameters and focus was fixed for all photos.

1) fglrx driver + XBMC xvba Frodo + Normal HDMI Video Range:

There is no black in picture 2), it's too bright. On the other hand, some grey is going to be black in picture 3). Pictures 1) and 4) are almost identical and look good.
In sum: in my configuration for fgrlx best option is "Normal", for OSS driver - "Expanded".

EDIT: XBMC option "limited color range (16-235)" in 3) and 4) was not active. When I activate it, picture 3) was OK and 4) was too bright.
