The smallest display diagonal of medium megapixel digital cameras that were launched around the same time as this digital camera is 2", the largest is 4.8", and the average display diagonal is 2.9". With a display diagonal of only 2.7 inches, the Samsung 77 has one of the smaller display diagonals amongst medium megapixel digital cameras of this age.
It may also be worth also looking at one of the other 2.7" screen digital cameras currently available including the Panasonic DMC-FT2, or the Samsung SAMSUNG ST96 which has better reviews.
If this Samsung digital camera display diagonal is not large enough for you then you might want to consider the Sony NEX-5 (£489.99) (3"), or the Panasonic Lumix DMC-TZ56 (3") which is also higher rated.
