Whenever "something" calls even the equivalent of "xrandr -q" the nvidia
driver will add such log entries. Given the frequency it's either some screen
config daemon or some broken (afair Qt5 used to do this) client code
determining the current screen geometry this way.

You can alter the way you start X11 (likely some DM) to pass
"-logverbose=0", no guarantees but it *should* silence this (and
everything else)
