How can I update graphical card?

To me that sounds like ‘buy a new one’

As to software updates … yes we are pretty up to date, and as a rolling release you will get updates for as long as manjaro exists … but Stable branch is a bit held back, because Stable. Especially with intel/modesetting I rather doubt you need to ‘update the driver’ … you already have the latest working one, and not much will change when you get the slight version bump.

Maybe you could explain a bit more?
And also share more info after seeing this:
