The nikkei 19 inches monitor has a resolution of 1440×900. Raspbian was not able to recognize the right resolution for the monitor so I had to tune the values into the config.txt file.

After a couple of hours I reached the goal.

I had to force the resolution using framebuffer width and height, then I disabled the overscan and tuned the top and bottom.

In the following few lines you’ll find the changes I did inside the /boot/config.txt file. Before apply any changes to this file, please remember to make a copy of it so you can restore your previous settings.

# uncomment this if your display has a black border of unused pixels visible
# and your display can output without overscan
disable_overscan=1
# uncomment the following to adjust overscan. Use positive numbers if console
# goes off screen, and negative if there is too much border
#overscan_left=-32
#overscan_right=-32
overscan_top=16
overscan_bottom=40
# uncomment to force a console size. By default it will be display's size minus
# overscan.
framebuffer_width=1540
framebuffer_height=880

Please let me know if this configuration works also with different 19 inches monitors.
