Blurry Images in IE on Wide Screen Dell Notebook

January 9, 2006 · 1 min read

I have a new Dell notebook with wide screen display at work (dell latitude d810 running on ati radeon mobility X600). This notebook
was shipped with default 120 dpi font size to make the fonts more readable (wide screen display is really cool, but now and than you want to read something on it as well ;-).

Anyway, if you use the default dell settings you may experience the problem with blurry images in Internet Explorer. This effect is due to the automatic scaling in IE6 and above. IE tries to resize the images so that everything looks the same as when everything is at smaller dpi, but does a terrible job at it, resulting in blurry and unreadable images.

 Change the following registry setting from 1 to 0 in order to disable this "feature":

 HKEY_CURRENT_USER\Software\Microsoft\Internet Explorer\Main\UseHR
