Talking Xperia E help please

Guys, I have a Xperia E Device ( C 1505) and I rooted it today. After rooting I downloaded an application called DPI Changer.After I opened the app and put its DPI Value to 190 and Rebooted the phone. I couldn't see things clearly as before. Now I want to set back to the phone in to previous state but I don't remember its old DPI value. I googled and found 164.95 DPI for Xperia E, and I put it,. But its not that much clear. If you have a Xperia E, Please tell me the DPI Value of your phone. Thanks in advance.
