Anti-Dither (1/2/off)
Anti-Dithering Mode is design to work with ATI graphic cards that
provide dithering output. Dithering output is used to make coloring
looks better than it's original color depth. It uses visual transient to
create a half-tone effect. However, this presents great difficulty for
Video Compression to maintain low bandwidth even if the source
display seems static.
Currently, we only see Dithering Output with ATI graphic cards.
To resolve this issue, AST1500 provides Anti-dithering for 1 bit, 2
bit, or off.
If the source content does not generate dithering output and this
feature is turn on. It will create a blocking effect because Video
Engine are unable to detect pixel changes. User can avoid this issue
by turning this feature to off.
Use Loopback
EDID(>A1.2)
This feature should be consider with the client side "Update EDID"
feature.
Update EDID
"Use Loopback EDID" & "Update EDID" feature is used for Multicast
Mode to select which monitor/TV EDID is used for system wide EDID
usage.
During multicast setup, there maybe monitor/TV that has lower
resolution. For example, 1 monitor/TV with 720p resolution with
mostly 1080p solutions. Please select the monitor/TV with lowest
resolution, to ensure all can be displayed correctly.
For customer that are using 1 pair of Host/Client with Multicast
mode, the end user must update EDID correctly. If not, it will cause
many compatibility issue.
