Every projector I've ever worked on that has an HDMI port. These include:
InFocus IN72, IN74, IN76, IN78
Planar PD7010, PD7060, PD7170, PD8130, PD8150
Vidikron Vision Model 15
Runco RS440, VX8D
Eventually, all of the displays I have any say in will have this ability. Now that digital sources have become pretty good at moving the bits, one of the most annoying problems left is getting the color space right. If you use REC601 to convert content created using REC709 then you destroy the color balance of the display (no matter how well you've calibrated it), and it's not completely recoverable using any display side controls since some of the data is clipped in the color space conversion itself.
By the way, in addition to the manual control, all of the displays listed above have an auto setting that first looks at the AVI Infoframe, but then chooses based on resolution. REC601 is used for SDTV/EDTV resolutions, and REC709 is used for everything else.
