You may want to be a bit careful with the 2515 since it's a 2560x1440 monitor in a smaller-than-usual size.
At the native 2560x1440 resolution, text and other UI elements are going to be pretty small. You might be able to compensate for that with a custom HiDPI mode using a third party app, but you may want to do some research on that first.
