Right now the U2410 is a much better deal than the LCD2690WUXi. So it has been recommended about the NEC in most instances, except for wide gamut editing where the NEC is first due to hardware calibration.
Yes, the Dell is listed as 1.07B colors because the LG H-IPS panel accepts a 10-bit signal. I still don't know if it is actually utilized in any way. After all, most video cards still output 8-bit although new ones are capable of 10-bit through HDMI and DisplayPort. Whether the Dell supports 10-bit through HDMI or DisplayPort I have no clue. Hopefully someone can prove that.
