There have been problems with color tinting in Dell's U2410 reported here before. But if you are confident that it wont affect your unit, then the U2410 will naturally be the better pick. The price gap should tell you which is the superior monitor. Not only does it have a absolute plethora of connectivity options, it is also using an IPS panel which allows for better color and picture quality as opposed to the TN panel being used in the ST2410.
