They are all 8 bit+FRC or 8 bit. Users who will not be using their monitor for work in color managed applications should forget about the bit depth #.
All of the 30" monitors are wide gamut=over saturated & inaccurate colors in games & movies. All 30" models except for the Dell 3014 (it has obvious overshoot ghosting overshoot
) and possibly the new Lenovo LT3053P have the same grainy matte coating as the CrossOver 3020MDP.
This image shows the affect of coatings on pixels, notice how unclear the 3020MDP looks.http://www.overclockers.ru/images/lab/2013/04/18/1/33_kristaleffect_big.jpg
Notice how clear 2560x1440 models like the U2713H/U2713HM/S27A850D/VP2770/PB278Q look by comparison. The 3014 (and possibly the Lenovo) has the same coating as the U2713H,.
For games & movies it is ideal to have a standard gamut monitor which tries to cover the sRGB/REC 709 color space. Using a 30" for gaming is the equivalent to throwing sparkles & glossy paint on a black & white painting.
Some 30" (Dell 3008/3011/3014) have sRGB modes but they are typically easily beaten by 200$ budget IPS in terms of over all performance (black levels, color preset accuracy, matte coating, input lag & pixel response times) and the Dells color settings are locked when using the sRGB mode.
Best to get a 2560x1440 monitor unless you don't care about art design/color accuracy. The Eizo EV2763W & ViewSonic VP2770 are the best name brand monitors and the overclock-able Qnix/X-Star are the best Korean modelsEdited by MenacingTuba - 8/6/13 at 1:54am
