The second monitor displays with a resolution of 640x480

Question

The system does not detect my second monitor connected the DVI. Appears in the settings of the words "digital device" and adjustment increase that I can set the resolution to 640x480. At D_SUB see each correctly.

What do I need to do to properly operate the space of two monitors?

system - Linux Mint 13,
Graphics Card - GeFroce GT520,
monitor 1 - ViewSonic VA1903wb (plugged into D_SUB),
monitor 2 - LG Flatron L1919S ( plugged into DVI using an adapter DVI--> D_SUB,
the nvidia drivers - version 304.60

Result of xrandr -q command.

I tried to add the code below, but it did not help.

This may be due to the adapter?

Answer 1

For anyone interested, the problem was on the side of the adapter. After replacing the adapter to another, the monitor is properly detected now it can also be freely configured.
