At Genos it's a 9 inch TFT Color Wide VGA LCD Size 800 x 480 dots.
Guess it's something similiar at SX900....
It's a good and responsive screen, top surface feels hard and like glass. Never had any problem during the two years of use.
Regulary cleaning with a soft dustcloth do the trick to keep it as new. 👍
