I am not an expert about computer monitor . I currently own a HP2311x 23 inches but I want to do some upgrade to the Asus VS247H 24 inches in the link given below. Is it worth the upgrade since the the contrast ratio is much higher in the Asus 24 inches? and why the 23" is more expensive ethan than the 24" ?. I mainly play FPS and DOTA2. does 24 inches really look noticeably bigger? Thank you
