[SOLVED] Linux Mint 17.2 screen resolution

Issue

I am fresh new on linux and tring to connect on a TV
rel="nofollow">http://www.cnet.com/products/samsung-ln-s325d/specs/ using DVI.
Problem: The screen resolution isn't good :(
I've tried many things with the xrandr command, but in the end, the new mode just doesn't work (black screen).

Here is the terminal:

frank@frank-Mint ~ $ cvt 1366 768
# 1368x768 59.88 Hz (CVT) hsync: 47.79 kHz; pclk: 85.25 MHz
Modeline "1368x768_60.00"   85.25  1368 1440 1576 1784  768 771 781 798     -hsync +vsync
frank@frank-Mint ~ $ xrandr --newmode "1368x768_60.00"   85.25  1368 1440     1576 1784  768 771 781 798 -hsync +vsync
frank@frank-Mint ~ $ xrandr --addmode DVI-1 "1368x768_60.00"

From there,

frank@frank-Mint ~ $ xrandr --output DVI-1 --mode 1368x768_60.00

or system settings > Display >1368x768 (16:9)

just gives me a black screen saying the mode is not available

I have tried many other resolutions, but any custom resolutions do that.

Anyone have an idea? thanks! :)

EDIT:

frank@frank-Mint ~ $ xrandr
