I'm having a really bad problem with the DPI settings on my Acer s7-392 laptop. The resolution of the display is 2560x1440 but at 100% DPI the text is too small to read.

I can fix this by increasing it to 150% but everything becomes blurred. Disabling the DPI virtualisation for a specific program also comes with the same result of everything being blurred.

Has anyone else experienced this problem and has a solution?

Have you tried, and is it an option, to drop the resolution down to lower 16:9 ratio resolutions? 1920x1080 for instance? –  panhandel Jan 9 at 20:16
    
the blurring is an artifact of pixel resampling and cannot be avoided except by not scaling. The real answer is to increase the font size (fonts are vector objects and are scaled mathematically before rendering to the "pixel grid"). But AFAIK, you cannot do this for e.g. the metro interface and apps. You probably can adjust the "classic desktop" in some manner, but this will not have much impact on the individual programs. ctrl+scrollwheel zooms in word and increases font size in many browsers. ctlr+0 resets to 100% –  horatio Jan 9 at 20:56
    
Actually, yes running at 1920x1080 at 125% DPI seems to be okay! Zooming helps a lot in Chrome. –  Cameron Jan 10 at 7:44
