Has loaded the firmware yesterday and it is the same, which was bought my pj ( which is C14 from first september ).
Work good, but Optoma remove BrillantColor option from menu
I do not know what is the default language because pj remembers the settings from the previous firmware.
I don't speak english, but fortunately, I understand a little
Again, sorry for my english.
Now I think what I do to Optoma was quieter. and how cool blue LED heat sink so as did not affect the optics and the floating focus.
