Remove the combing effect on images
When frames are interlaced, artifacts from one frame may appear on the next frame. This occurs when a fast
motion video is interlaced. Since each frame is captured from a different point in time, the action captured in
one frame is carried over to the next frame. The result is a blurred image and horizontal lines running across
the video.
To convert an interlaced source signal to a non-interlaced signal.
1. Connect to the admin interface using your preferred connection mechanism. See
Connect to the Admin
Interface
.
2. Login as admin.

from the Configuration menu; the Frame Grabber

Force the video source to use a specific resolution
Extended display identification data (EDID) is data provided by a video display device (usually a monitor) to
describe its capabilities to a video source. The video source uses the EDID to determine the capabilities of the
monitor to determine the resolution, color depth and other settings that the monitor can support. EDID is
crucial for DVI sources but mostly ignored by VGA sources.
When you connect the VGADVI to a video source, the video source sees the device as a monitor. Just like a
monitor, the VGADVI contains the EDID that is used by the video source to determine the video signal to send.
Upload a new EDID
In most circumstances the factory installed default EDID, is sufficient. However, there may be some cases where
a video source uses resolutions that you do not want to use. In that case you can choose an EDID that forces
the video source to use a specific resolution.
The uploaded EDID is permanently installed on your VGADVI and will always share this EDID with the video
input source.
