I am trying to connect an LCD monitor whose optimum resolution is 1360
x 768 but I cannot find that setting in control panel even after a cold
boot with the new monitor connected. Is this because I am limited to
only those resolutions supported by my video card? If not, what must I
do to set the resolution to 1360 x 768?
A guiding principle, is the hardware itself is flexible, and able to
produce any H x V, as long as the values meet some constraints.
With older hardware, the horizontal had to be divisible by 8.
The vertical value, divisible by 2.
So, for example, 1368 x 768 or 1360 x 768 should be achievable.
(A value like 1366 x 768 can be achieved if a GPU has an external TMDS
used to drive the DVI digital output. This is not info you find on the
back of the video card box.)
This concept of flexibility has been around so long, it was available
on the frame buffer chip I used more than 20 years ago. Even back then,
I could define H, V, front porch, back porch, and so on, and it would
work as long as I didn't break the monitor.
If you were to take your hardware into Linux, you'd find that
with the "Mode Line" stuff in Xwindows, that more of these
resolutions would be supported in software. But it can be
a hair-pulling experience there as well. In Windows,
there is the notion of "protecting the user from themselves",
to prevent damage to monitors that cannot withstand out-of-range
settings. One brand of video card, even had a custom resolution
dialog box, to set the values.
Some of the video drivers, have APIs that allow selecting these flexible
options. The utility "PowerStrip" from Entechtaiwan, takes advantage
of the software API, to allow setting the resolution.

That site also has a forum, and FAQ pages. In it, they discuss issues with
laptop chips. Laptop chips really don't differ with their internal design,
but the support issues are different. A laptop chip may not have Plug and
Play, for the main LCD panel in the laptop. Sometimes, a custom driver
is shipped with the laptop, and that takes care of the hardware (it is
really a standard driver, with a custom config file added). There
may be less uniformity in laptops, preventing the author of PowerStrip
from covering all the chips used.

So, if you have an ATI or Nvidia video card, in a desktop system, chances
are good that PowerStrip can give you want you need. If you have a laptop,
the situation may be more dynamic. I haven't been following the
developments, to see how much progress has been made.
This is an example of playing with Intel laptop graphics, to try to
get a custom resolution. It can be done. This is a long thread,
and you can suffer hair loss, from just scrolling this page

Good luck,
