Thanks. The only reason I ask is that I swear when I first started using it, when booting the Pi it would present a test pattern window whereas the latest version boots to a black screen, which threw me for a bit. Haven't had a chance to dig any deeper, but of course it would have been obvious just changing the TV settings as well. Doh.Yes, its set to output full RGB by default.
(Also, if you have to ask for that..
Do a 10 point greyscale reading. Look at the brightness graph. Switch the setting on your TV. Repeat. Look at the brightness graph. Chances are, you can even do it in one set of readings. )
In your calibration software use 16-235 colors, they will get auto converted afair (but it has been close too a year that I used it last - so please correct me if I'm wrong (small chance )).
