What determines whether I need the standard or DCH version of the latest Nvidia driver? I have several machines under my care, all W10 latest version/update, and all UEFI. Yet, some want standard drivers and some want DCH. The only difference in the machines (mainly) is the Nvidia video card. I read Nvidia's explanation of the difference between DCH and standard, but I can't seem to understand why nearly identical machines don't all take DCH.
