I'm having problems with my GT610 video card and the proprietary nvidia driver, my second monitor showing an incorrect resolution.
I have a full HD display with 1920x1080 resolution connected to HDMI-0 which correctly displays the resolution, and I also have a "FLATRON E1941" monitor with 1366x768 resolution connected to VGA-0, however this one encounters problems, the nvidia driver auto-detects 1280x720 and the closest native resolution is 1368x768, when I use the nouveau driver the resolution in VGA-0 is detected correctly.
Some exits:

It doesn't seem as if you added the mode, but its among the detected resolutions.
However the default is 1024x768 (from VESA requirements) and you're running it at 1280x720
Please post xorg logs w/ nvidia and nouveau.
Also just running "xrandr --output VGA-0 --mode 1368x768 --right-of HDMI-0" will get you the desired mode.

Probably this is the result of almost a month searching the internet trying to solve this problem

This part I did not quite understand, but
Nvidia log:

Nouveau log:

this causes a poor rendering on my secondary screen (VGA-0), basically the pixels are cut
thanks for the reply

Initially the desired modes are selected. Also I don't like

I suspect interference from your desktop session - KDE?
Try to suspend the compositor before altering the mode (Shift+Alt+F12)

I got to test with several DE's (gnome, Cinnamon, deepin) this problem appears in all DE's

Well, the posted xorg log doesn't explain the xrandr output. Something *must* happen inbetween.
Cut out your DM (use startx, post the used xinitrc) and all DE cruft (just run an xterm. openbox, if you must).
Esp. ensure you're not running some arandr daemon.

Sorry for delay. I found the solution with your request to show my nouveau.log. thanks
What did I do?
First I looked in the file(https://pastebin.com/DYcrj36T) for the correct resolution, which I found on the line: 271
[ 33.692] (II) NOUVEAU(0): Modeline "1366x768"x59.8 85.50 1366 1436 1579 1792 768 771 774 798 +hsync +vsync (47.7 kHz eP)
although the command cvt 1366 768 return 1368 768, using the resolution I found in the file I gave the following command:
xrandr --newmode "1366x768" 85.50 1366 1436 1579 1792 768 771 774 798 +hsync +vsync
xrandr --addmode VGA-0 1366x768
xrandr --output VGA-0 --mode 1366x768
And this works, i found in my DE the correct resolution for my secondary monitor
well, command cvt 1366 768 still returns 1368 768
