ok, so gimp is indeed using 10 bit display.
If you make a new image in 32-bit floating point, 1024 pixels wide, and
make a gradient across the window, is there visible banding?
What format are your test images in?

The test files from EIZO are:
* TIFF: 8 bit non-linear integer for the 8 bit gradient 1600 x 1200
pixels and
* TIFF: 16 bit non linear integer for the 16 bit gradient 1600 x 1200
pixels .
I use these test images

8_bit_gradient TIFF:

I prefer to use the test files from the links, as requested and
recommended by my monitor supplier EIZO.
Why is it so critical to have 32-bit floating point, 1024 pixels wide?
