programs on TVs capable of displaying any of those
resolutions.

of incoming video formats and TV display capabilities,
you simply press V.MODE button on remote control
to set to match the highest resolution your TV is
capable of displaying. (If you're not sure about your
TV's resolution, see your TV's manual for this
specification.)
PHD-8VX will then do the appropriate conversion
from input signal format to display format.

Aspect ratio
In addition to resolution and interlacing, HDTV is also
defined by the aspect ratio of its broadcasts.
Aspect ratio means the shape of the screen as
defined by the ratio of the screen's width to its height.
For analog TV and SDTV, the aspect ratio is 4 units
wide by 3 units high (usually written 4:3).
This is familiar shape of conventional TVs----slightly
wider than they are tall.
For HDTV broadcasts, the aspect ratio is 16:9
(nearly twice as wide as it is tall).
This is, not coincidentally, more like the shape of
movies shown in theaters.
This makes HDTV an ideal format for broadcasting
and viewing movies on a TV.
But what happens if you are watching a nearly
square-shaped 4:3 broadcast on a rectangular 16:9
TV. The PHD-8VX, Full HD 1080p HDMI A/V
Switcher Digital HDTV Tuner Receiver Media Box,
allows you to choose from a variety of screen
formats to help you dealing with those scenarios.
• PHD-8VX is providing several options to change
to different screen formats as: Normal, Full
Screen, Panoramic, Zoom1, Zoom2, Direct and
Custom options.

different TV sizes. User needs to first select
Custom option during Aspect ratio menu screen,
then bring up main MENU → Set up → Scale
Window to fine adjust screen size. See page 22
for details.
Screen format examples
To deal with the mismatches that can occur between
the shapes of TVs and the aspect ratios of program
broadcasts, the Digital HDTV Tuner provides you
with a set of screen format controls.
These controls allows you to pick a format to use for
both 4:3 TVs showing 16:9 programs, and for 16:9
TVs showing 4:3 programs.
Here is an explanation of the options. (Details for
setting this preference are included in page 24).
