DVI/HDMI signal compatibility: some display devices may only support HDMI or DVI video
signal and execute wrong signal format detecting. The default output is HDMI. User can
change output with DVI format through [Options]→ [Setting]→ [DVI]→ [On].
Usually, to swap with different cable, output channel, signal source and monitor can verify the
root cause for the failure.
Signal compatibility issue, user can add one HDMI splitter/switcher in the middle to change
signal impedance. This may fix the issue.
Use the highest resolution and number of color bits (RGB 4:4:4) at source that supported by
EdgePro whenever possible.
Quality of Source Signal, ensure your source output is of the required quality. The EdgePro will
not improve a lower quality source signal. Assess color sampling bits, compression
technology etc of the source.
If the use of H.264/H.265 compressed files, please select a player with hardware decoding to
get smooth video quality.
If the input signal is interlaced signal (interlaced-1080i), and the image is rotated or flipped,
then the channel will have no [3D Motion adaptive de-interlaced] processing function. If user
applies static image source, the output video will have a slight jitter phenomenon. The
processing channel quality will be reduced. Use a progressive signal source setting
(1080p/2160p) if possible.
Please press [INFO] shortcut key to check the input/output signal settings.
The position shift in the projector will be enlarged to more than 10x due to projection distance. One
mm image shift inside projector may appear 1cm image shift on the screen. User will clearly see
blurred effect on overlap region in edge blending setup.
There can be some image position shift after system setup for the following reasons:
•
Thermal drift due to projector internal temperature change. When power on the
projector, the temperature is lower. After 20-30 minutes, the image position shift may
be up to 5-10mm. It will be more obvious in overlap region. Different projector will have
different thermal drift range.
•
Stability of mounting system.
•
Projector structure change after installation due to weight and thermal effect.
