My understanding is that you may need to define an appropriate
metamode specifically for the display combo. Also, since
"ExactModeTimingsDVI" has been applied, you may need to
add a modeline for the second display.

I guess the OSD doesn't like the timing value. You may try playing around with
them, i.e. increase the pixel clock or play with the horizontal sync signal.

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

maybe this helps
