[SOLVED] DCH vs Standard Nvidia Drivers

[box o rocks]

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.

Hi

Seems that the difference is based on this

NVIDIA DCH Display Drivers are supported on Windows 10 x64 April 2018 Update (Version 1803 OS Build 17134) and later versions

But I've got the latest on all my Win 10 machines. That's what I don't get. They are all post-1803.

I'm an idiot. My machines are not all UEFI. The ones that take the standard driver are still legacy BIOS. That must be the difference. My apologies for distracting folks.

Perfect.

You do not need to apologize, we all learned somethig.
