Thanks for joining the community.
I understand you have some questions about graphics driver version number.
Please take a look at the link below to understand driver versio numbers:
Display audio driver is included on the graphics driver to support HDMI. The driver provides the codec to enable HDMI.
Allan, thank you for the reply. However, I was already aware of the link that you provided. The content simply describes how to interpret the individual components of one of the version numbers, namely 10.18.10.3496 in the example I gave, but that was not what I was asking.
What I wanted to know was why the graphics driver has two version numbers, namely 18.104.22.168.3496 and 10.18.10.3496, and what is the difference between the two.
Drivers are often referred to by either build number or driver version:
DX OSver Build number
15.33.18. 64. 3496
win8 DX Build number
10. 18. 10. 3496
There is no difference between the two. The rest of numbers are just for internal reference.
