Why do the coordinates of the graphic tablet go astray?

Question

Graphics tablet

The bottom line is that for no reason the tablet began to "mow" to the right in coordinates.
That is, the click is made in two places at once. Which I do and the one that shifts. Moreover, the more to the right my click, the less mows.
Here is a video clip to illustrate.

It is worth noting that the problem, I assume, is clearly related to screens / monitors.
Because when this mode is used (Screen 1)

, in fact, the space of two monitors is used, on the surface of the tablet, the entire area is also used.
But if you select "all screens",

then all monitors are also used, but at the same time, exactly half of it (right) is used on the tablet surface itself. That is, two monitors are projected only on the right side of the tablet surface.
And if you select "Screen 2", then the cursor flies to the left, to the border of the left monitor and does not get out of there. That is, it moves, reacts, but it seems to be imprinted, as if it refers to a monitor outside of this monitor.
Of the latest manipulations with monitors, it was only their connection to one video card. From that moment to this, I have not used a graph tablet.
Previously, there were also two monitors and everything worked ok.

Answer 1

UPD:
When you turn off one screen, everything starts working fine on the second.
