I can\'t say that I would expect the viewability to be the same outdoors as indoors, but the point of the transreflective screen is that it should be reasonably viewable in direct sunlight. I have had my 5500 in direct sunlight, and I would say that it was quite viewable. It wasn\'t necessarily bright, but it definitely was readable. On the other hand, the viewability of my 760 in direct sunlight is terrible, practically unreadable. Which is expected as it\'s not transreflective.
