15. Helpful tips for video wall settings
➢
Image distortion and aspect ratio issues
If the content aspect ratio is different from video wall, it will cause image distortion. User can adjust
aspect ratio through [Overlap] settings. However, you will have two choices:
➢
Full screen display but some content will be drawn to outside border and missing.
➢
Draw the image into video wall and keep some blanking border at some edge.
➢
If the signal is from PC, user can set customized EDID in GeoBox to let PC output expected output
resolution. Some PC may not follow GeoBox EDID resolution setting and require customized output
setting from display card or reboot PC system.
➢
User can set different video wall settings in each channel and crop different area for the display. In
combination with ZOOM, PAN and OVERLAP settings, user can crop any location of the image for
each LCD, no matter it is in landscape or portrait position.
➢
Pay attention to image rotation limitations in input signal resolution. G406s doesn
’t have 90/270
image rotation function when the input is 4k/60 Hz.
➢
Please apply signal source before video wall setting. Otherwise the settings may be wrong.
➢
G406s can support interlaced signal source (i.e. 1080i). However, if user rotates or flips the image,
there will be no 3D motion adaptive de-interlaced function. User may see some small flick image
while the input is still image. We recommend applying progressive signal for the best video quality.
➢
Some media players will output maximum resolution when it is powered on each time but not follow
the EDID settings in sink device. It will cause abnormal display in the video wall if this video wall has
image rotation setting and the signal source resolution is more than 4k/60Hz because G406s can
only support image rotation under 4k/30Hz source signal.
➢
Please make sure no Over-scan setting in monitor. Otherwise, the image position will be wrong.
16. Limitations in Image Flip and Rotation
Image 90/270 degrees image rotation is only available in input resolution under 4k/2k @30Hz
(included). While image is rotated or flipped, there will be no 3D motion adaptive de-interlaced function.
We recommend apply progressive source signal to get the best video quality.
