Ubuntu – How to set up native monitor resolution of 1680 × 1050 with Nvidia Geforce 210 on Ubuntu 14.04

I use a video card Nvidia Geforce 210.

According to it's specs it can run :Maximum Digital Resolution 2560×1600 and Maximum VGA Resolution 2048×1536.

I use Ubuntu 14.04 LTS with NVIDIA-Linux-x86-340.96.run driver instaled and activated and the maximum resolution I get is 1360×768 that is to narrow and 1152×864 that is to wide on both of my monitors (used as expanded):

1. Optiquest Q201wb 1680 x 1050

2. Iiyama prolite e2200ws 1680 × 1050

Can you give me an advice on how to make my resolution 1680×1050 permanent(not only until first reboot)?

Whith nouveau display driver it's the same thing as is with Nvidia driver 304.131

PS. I saw [this similar post]Cant get full resolution on Second monitor with nvdia geforce 210 on 14.04) but I don't think it's the same problem.
