Excellent screen. All ur experience on a tab/smartphone is most importantly affected by the screen. And this tab has an very nice screen. It has Full HD resolution with 1900* 1200 pixel which give an effective ppi of about 320 ppi which is the same ppi as we get on a iPad mini with Retina Display. In short its a wonderful display.
