Frequently asked questions
What is the maximum pixel capacity of the KBS2000 Pro?
The unit supports up to 8.85 million pixels. Each Ethernet output supports up to 650,000 pixels; multiplying the number of ports by the per-port limit does not increase the total unit limit.
Does the KBS2000 Pro accept 4K at 60 Hz?
Yes. Its HDMI 2.0 and DP 1.2 inputs support up to 4096 × 2160 at 60 Hz. The specification also supports custom resolutions within the stated input pixel limits.
Are optical modules included with the sending box?
The specification states that optical modules for OPT1–OPT4 must be purchased separately or selected as an option. Confirm the required module type before ordering.
Can the KBS2000 Pro display 3D content?
Yes, with a 3D transmitter and 3D glasses. The specified loading capacity is halved in 3D mode.
Can I synchronize several sending boxes?
The device supports Genlock using an external synchronization source and cascading control for up to 8 units through its Gigabit control connections.
