I don't know about controls. I just put

where it will get run when X starts, with whatever mode I want used
uncommented. It works as expected on Jessie with TDE.

Or, use

or one of the others in that directory as a skeleton to create an xorg.conf
file, uncommenting or creating the appropriate PreferredMode line. I don't
recall trying this on Jessie, but it works in Kubuntu/TDE,
Linuxmint/Cinnamon, Mageia/KDE4 (with kscreen disabled), Fedora/KDE4&5 (with
kscreen disabled) and openSUSE/KDE4&5 (with kscreen disabled).

I don't recall running across that one before. 16:9 @768 is 136X.

A quick search for 17" AOC 16:9 suggests it should most likely be
preferred/native 1600x900. What modes are listed by xrandr and/or Xorg.0.log?
"The wise are known for their understanding, and pleasant
words are persuasive." Proverbs 16:21 (New Living Translation)
