This document discusses four issues related to graphic card drivers from ATI and NVIDIA. It provides information on the conditions that trigger each issue, descriptions of the issues, and resolutions which involve downgrading the graphic card driver version. The issues covered are: 1) time clock issues with ATI drivers, 2) jagged live view images with ATI drivers, 3) color issues in live views with NVIDIA drivers, and 4) lag in live views on digital matrices with NVIDIA drivers. Downgrading the drivers is listed as a resolution for all four issues.
