Release Highlights
To enable the latest DisplayPort 1.3 / 1.4 features, your graphics card may require a firmware update.

Without the update, systems that are connected to a DisplayPort 1.3 / 1.4 monitor could experience blank screens on boot until the OS loads, or could experience a hang on boot.

The NVIDIA Firmware Updater will detect whether the firmware update is needed, and if needed, will give the user the option to update it.

If you are currently experiencing a blank screen or hang on boot with a DP 1.3 or 1.4 monitor, please try one of the following workarounds in order to run the tool:

Boot using DVI or HDMI
Boot using a different monitor
Change boot mode from UEFI to Legacy; or Legacy to UEFI.
