Editing ClearType (section)

==Sensitivity to display orientation==
Because ClearType utilizes the physical layout of the red, green and blue [[pigments]] of the LCD screen, it is sensitive to the orientation of the display.

ClearType in [[Windows XP Media Center Edition|Windows XP]] supports the [[RGB]] and [[BGR (subpixels)|BGR]] sub pixel structures; rotated displays, in which the subpixels are stacked vertically rather than arranged horizontally, are ''not'' supported.<ref>{{Cite web |url=http://www.brandonfurtwangler.com/?p=54 |title=Tablets and cleartype, and a requested feature of Avalon at Brandon Furtwangler blog |access-date=2006-12-02 |archive-url=https://web.archive.org/web/20061014120627/http://www.brandonfurtwangler.com/?p=54 |archive-date=2006-10-14 |url-status=dead }}</ref> Using ClearType on these display configurations will actually reduce the display quality. The best option for users of Windows XP having rotated LCD displays ([[Microsoft Tablet PC|Tablet PCs]] or swivel-stand LCD displays) is using regular [[anti-aliasing]], or switching off font-smoothing altogether.

The software developer documentation for [[Windows CE]] states that ClearType for rotated screens is supported on that platform.<ref>[http://msdn2.microsoft.com/en-us/library/ms901093.aspx Working with ClearType Fonts<!-- Bot generated title -->]</ref>
