A number of users of Nvidia's GeForce GTX 900 series and GeForce 10-series have experienced problems using newer monitors connected via DisplayPort 1.3 or 1.4. Problems have ranged from blank screens to the inability to properly boot up at all. Unfortunately, regular driver updates cannot fix the problems that many users have experienced. That said, the fix is now available to flash the BIOS
of affected graphics cards. Nvidia's tool first unloads the existing driver from your system and then proceeds to flash the BIOS of your GPU. Do not interrupt the process during this time since a failed flash attempt could lead to serious problems. This firmware update tool should only be run if you are experiencing any problems running a Maxwell or Pascal-based graphics card with a DisplayPort output. Following the flashing of firmware, a restart is recommended.
To be able to run the tool if you are unable to boot with DisplayPort, you must use a DVI, HDMI, or VGA cable instead or use a different monitor all together. Nvidia also recommends changing boot modes from UEFI to Legacy or from Legacy to UEFI. Forcing use of integrated graphics is also an acceptable solution in order to run Nvidia's update tool.
