Setting Function
Protocol
Set the communication protocol to P3K or Legacy (see Section 11 ) E
When setting the Protocol to Legacy, some PC applications
(for example, K-Upload) as well as the Web pages may not
function properly.
Test Pattern Set the Test pattern to Slide Bar (non-HDCP), Color Bar (HDCP) or Off.
Each test pattern includes a sinusoid audio signal at 10dB @1kHz.
We recommend that you set the Display Mode to Single Window (see
Section 6.2
) and set the Output Resolution to 1080p (see
Section 6.7
).
Note that the Color Bar test pattern changes the OSD menu coloring and
the following message appears on the display: “Ignore OSD Coloring”
Factory Reset
Reset to factory default values (see Section 10.1 ) E
Once Factory Reset is enabled, a countdown appears, letting you cancel the
process and revert to the previous state
6.8.1 The Luma Keying Feature
The luma keying feature lets you display the PiP window (the key image) as semi-
transparent over the main window. This feature can be used to have the PiP
window display a static or dynamic logo, for example, which will appear on a
transparent background.
To apply the luma keying feature, first set the PiP window to the desired size and
location and then turn luma keying On. The PiP image will show without its
background.
The lower the luminance in the PIP window, the more transparent it becomes, thus
letting the main window image show. The higher the luminance, the less transparent it
becomes, not letting the main window show through. To use this feature it is
recommended to set the PIP image as follows: use low-luminance colors for the
background (the key image portion) and high-luminance colors for the logo.
For certain displays, the screen may flicker once for about a second
after adding or changing the luma keying setting.
Since luma keying is a volatile parameter, it may reset unexpectedly
following a change in the setup. So we recommend that you activate it
after completing the setup.
When the luma keying feature is On, any change in the setup (either
by the user or by resetting due to a setup change) may cause the
screen to flicker once. The luma keying will recover automatically after
resetting.
