When using older Intel graphics products, the native resolution of some displays, such as 1920x1080, 1680x1050, and 1440x900, is not available in graphics properties. The display extended display information data (EDID) does not read properly when connecting to a subset of digital flat panel (DFP) displays.
Intel has drivers to specifically address this issue that can have longer than normal resume times from standby. This solution only works with external displays, and will not address issues with a built-in display. Intel provides these drivers as is and has not tested, nor provides warranty, to the operation of the driver for this purpose. Select your product and operating system from the table below in order to locate your driver.
This issue does not occur on newer Intel graphics products such as 1st Generation Intel® Core™ Processors with HD Graphics and newer. If you are using a newer product, refer to the Display Resolutions frequently asked questions for further troubleshooting.
