Consider the following scenario.

• You use a Windows Vista-based computer.
• You use a widescreen monitor that is attached to a video card.
• The video card uses a Uniform Memory Access (UMA)-based video card driver.

Note UMA-based video card drivers are associated with integrated video chipsets. There is no indicator in the operating system that informs you whether a driver or a chipset uses UMA architecture.
In this scenario, if the Windows Experience Index (WEI) score is greater than or equal to 3.0 in Windows Vista, slide show pictures are not displayed in the center of the screen. Instead, the slide show pictures are displayed on the left side or the right side of the screen.
