When you start a slide show in Windows Photo Gallery on a computer that is running Windows Vista, pictures in the slide show are not displayed.


When you start a slide show, Windows Vista uses the Windows Experience Index ratings for Graphics to determine whether to use the DirectX Exclusive mode or the GDI+ mode to draw the images. If the DirectX Exclusive mode is used to draw the images, the progressive scan mode is always used. However, the display may not support the progressive scan mode or the non-interlaced scan mode in the current resolution. In this situation, you experience the issue that is described in the "Symptoms" section.

Note Some displays only support the interlaced mode in specific resolutions. For example, many plasma and LCD televisions use the 480i mode or the 1080i mode. In these examples, the letter "i" signifies "interlaced."
