I really don't think you can make this assessment based on a photo of your monitor.
Even if your display were perfectly flat, which it isn't, and it also appears to not be aligned correctly judging by the curvature of the text, it still wouldn't be a good test.
Does this happen with all of your photos ?
Try posting another, not of your monitor, even a blank wall. Then someone may have an answer to your problem, if in fact there is one. (Meaning if you only see it with a pic of your monitor).
