I bought a brand new Sony VAIO touchscreen laptop with windows 8.The laptop is full HD with a resolution of 1920 x 1080.

However i immediately noticed that everything looked too tiny.The text was difficult to read and the taskbar and icons were too tiny.So i went in "Display" and changed the DPI to Large (150%).Now everything is just the right size however a lot of the text is now blurry especially the text on Chrome browser and any installer and various other programs.

When i don't change the DPI,there is no blurriness but everything is tiny and if i increase the DPI everything is blurry.
Upgrading to Windows 8.1 did not help.
