It's a TN panel. The pixel density is higher than the 27in version. I think I read it about 13% higher than the 27in one. Don't quote me on that. Look it up or do the math to be abs sure. There's a menu option in terms of reponse time: normal and fast. Pcmonitor/info website said to just leave it at normal. That website also said the input lag was like 25ms. Which is low. Look up the website for more info.
