Here's the meaning of the the first five values of the given modeline:

Pixel clock in MHz: 257.0
With this setting, the vertical refresh rate is only 257000000/2174/2080=56.8Hz.
For a 60Hz refresh rate you would need a value of 271.31.

Number of displayed pixels: 2048
You should not change this field since it perfectly fine fits
to your display.

Number of (non-displayed) pixels from the beginning of the
display area to the beginning of the sync pulse:
So the so called "back porch" is 2080-2048=32

Number of (non-displayed) pixels from the beginning of the
display area to the end of the sync pulse:
So the so called "sync width" is 2112-2080=32

Number of (non-displayed) pixels from the beginning of the
display area to the end of a horizontal line:
So the so called "front porch" is 2174-2112=64
Thanks for the information. Unfortunately I have already dismounted the setup with which I was testing. It was important for me just to see if it works. Now I know we can also buy cheap graphic cards instead of BARCO graphical boards which cost fortune compared to NVidia. And it works great.

When I will connect it again I will try other frequency settings.
