5.3. DisplayPort Video Options
DIFFERENCE:
DisplayPort inputs are available in certain models, -D letter in the model name refers to that
(see the
Model Comparison
table).

If the emulated EDID does not support the deep color signal (10, 12-bit), and the incoming video is
deep colored, then the video processor converts the signal to 8-bit automatically. The compatible
color depths can be checked in the
software.
The factory default EDID (F49 - 1920x1080p60.00Hz) has deep color support up to the full HD
▪
resolution. When the resolution of the incoming video signal is more than the full HD with deep color
(e.g. 4K@30Hz with 10-bit or 12-bit), the color depth is reduced to 8-bit.
▪
If the signal is 4K@30Hz with 10-bit or 12-bit, using F146 EDID (3840x2160@60Hz with deep color
support) is highly recommended.
▪
DisplayPort signals over 18Gbps will be converted down by either truncating bit depth or by converting
RGB signal to YCbCr 4:2:2 12-bit signal based on user selection. The second option will not reduce the
color depth, instead it results in loss of chroma information.
▪
The video processor converts the DisplayPort video signal to HDMI in all models.

5.3.1. Color Conversion
The table below gives an overview about the automatic color conversion of the video signal. This conversion
happens without any user intervention, in color conversion setting (4:4:4 to 4:2:2); in the DP output port this
is not available.
