Nvidia has released a firmware update tool for its new GeForce RTX 4090 and 4080 GPUs to fix a bug that could break display output, causing the GPU to show a blank screen when being used without drivers installed. The issue only affects "certain motherboards," and Nvidia says it "should only be applied if blank screens are occurring on boot." (We installed it on an RTX 4080 Founders Edition in an Asus motherboard that was working normally and didn't notice any adverse effects.)
