Default Colour Presets
The Dell S2740L comes set to the Standard mode by default and is very bright. The Standard mode provides the best colours, which are simply amazing, once the brightness is turned down to 35. The Dell S2740L also has a very, very minor green tint, but it has the least colour dominance I've seen on a display, ever. The S2740L looks a little washed out due to the low default gamma, however once the brightness is decreased (I randomly chose 35), the gamma averages around 2.26 (2.22 is the target), resulting in gorgeously saturated colours and proper shadow detail.

The Dell S2740L has three out-of-the box issue
1.) very, very minor green tint...it has the least amount of a colour dominance I have seen on a display
2.) slightly washed out gamma due to the low default gamma.
3.) Black bezel is so dark the blacks can't blend with the bezel like they would on a display with a normal bezel,
4.) The blacks always look grayish due to the use of glass
Once the brightness is turned down, the Dell S2740L's image quality becomes essentially perfect, and as good as it gets, and the contrast rises to a phenomenal 1200:1! Remember that the use of edge-to-edge glass makes the Dell S2740L more reflective than a regular glossy display and the blacks look grayish so the high measured contrast ratio is basically meaningless.
