"Native resolution" means the actual physical resolution. All flatscreen
TVs I know of are either 1920x1080 or 1280x720.
I'm assuming you are using a laptop with 1360x768 resolution. This will
not fit smoothly into the TV's resolution, so even before resizing the
Display you have problems: the display will not be as clear and sharp as
on the laptop's screen. But at "normal viewing distance" you will not
notice that. Good thing, too. ;-)
OTOH, if the graphics/video system in your laptop can set the screen to
the TV's actual resolution, set it up that way. The laptop's display
will now be a bit off, but on the TV everything will look as good as it
can.
OK, now I understand what you mean by changing DPI. DPI is a confusing
concept. "Dots per inch" is not at all the same as pixels. A pixel is
actually 3 dot, cyan, magenta, and yellow, with each dot displayed at a
different intensity for a given colour. The screen has a fixed DPI.
(That's why using a TV as a monitor is not always a good idea.)
AIUI, enlarging the Display actually changes the number of pixels used
to display an object, which in effect changes the DPI of the displayed.
That is, the OS increases the size of the pixel box within which objects
are displayed. Eg, instead of, say 32x24 to display a letter it will be
40x30. The OS will attempt to provide a smooth letter, but will fail, so
while the letters are larger, they will be more or less fuzzy. This
larger-but-fuzzier effect will be objectionable for some objects. (which
is why I don't do what you've done).
This is also why enlarging Display will truncate the windows. Eg, at
125%, the full screen will be displayed as 1700x960, which doesn't fit
into your 1360x768. So parts of the window will be cut off. If the
window is locked into full screen, you will not see the cut off parts.
If it's not in full screen mode, you can move it around and reveal the
hidden parts. You'll find keyboard shortcuts at:
