I get the same result on my laptop using 270.41.06 driver and several
versions of nvidia-settings. But I never looked at this before, so I
can't say whether this was working with older releases.
Eventually a driver problem.

I don't think so. But as the nvidia-settings package is built from free
source code, you might want to try the binary built by nvidia. Download
the driver *.run file from
ftp://download.nvidia.com/XFree86/Linux-x86_64/ to a temporary directory
and run it with the --extract-only command line option so that it does
not start the installer. The nvidia-settings binary can be found in the
root of the tree that is being extracted. Switch to that directory and run
./nvidia-settings -q GPUPowerSource -t

Downgrading to 260.xx does not work due to missing support for Xorg
1.10, but eventually you could try the newer driver from experimental
(275.xx) and see if this was fixed.
A quick search in the NVIDIA forum found the following threads:
