result. Users can select the following resolution settings:
Horizontal:
1920 or 3840,
Vertical:
1080 or 2160

If FHD content, please apply the FHD input resolution.
b. For dual SB-3403’s horizontal cascading, 3840x1080@60Hz will get the best video quality.
c. For 2x2 (4) SB-3403 cascading, 3840x2160@30Hz input resolution will get the best video quality.
