https://www.pcgamer.com/nvidia-releases-a-gpu-firmware-update-tool-to-support-4k-hdr-monitors/ > Now that 4K monitors with HDR support are starting to arrive, the question is, what do you need to run them? A beefy graphics card, for one, at least for gaming. However, you might also need to update the firmware on your GeForce graphics card, so Nvidia released a tool that will detect if that's the case, and apply the update as needed. > Nvidia acknowledges in the tool's release notes that without the update, systems connected to a DisplayPort 1.3 or 1.4 monitor could experience blank screens on boot until the OS loads, or in some cases they might hang during boot.
