The resolution is obviously very high and the screen is nice and clear, but I compared it side by side with my partners S3 and her screen seems to 'pop' a lot more. Her colours just look brighter and warmer where as my 920 seems a little dull in comparison (crisp, but dull).
Maybe I need to mess around with the settings.
I've found that my 920 has a turbo brightness mode it goes into when I put it in direct sunlight. Try getting into that mode.
