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?

slave liam

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
16_bit_gradient TIFF: 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?
