KBS2000 Pro LED display sending box
The Kystar KBS2000 Pro sends video to LED displays in rental and fixed installations, including concert stages, event venues, conference rooms and exhibitions. It accepts HDMI 2.0 and DP 1.2 sources and supports up to 8.85 million output pixels through 20 Gigabit Ethernet ports and four optical outputs.
HDR10, HLG, 3D LUT adjustment and Genlock provide options for color processing and system synchronization. Check the input timing, total screen pixel count and load on each Ethernet output when planning a display.

Single Ethernet port supports 650,000 pixels; maximum total unit capacity: 8.85 million pixels; maximum width per unit: 8000 pixels.HDR display.
Supports HDR10 and HLG standards.3D LUT function.
Supports color adjustment of video sources via 3D LUT files.Genlock function.
External synchronization source signal for system synchronization.Supports EDID management.
Maximum input resolution: 4096×2160@60Hz, customizable within this pixel range, maximum width 8000, maximum height 8000.Supports passive luminance and chrominance correction.
When used with the KESDA correction system, it can perform luminance and chrominance correction for each LED point independently of the video source, eliminating brightness and chrominance differences and ensuring consistent display across the entire screen.Fast correction data transmission.
Supports KESDA’s fast correction data transmission technology, twice as fast as traditional methods, significantly improving correction efficiency.Spherical shape adaptation.
Uses built-in algorithms to support various types of spherical screens, compatible with KR, Hxs, and Mx series receiver cards.Supports arbitrary cable routing.
No rectangular load limitations; empty areas do not occupy load resources, improving network port utilization.Supports multiple control methods.
The device supports USB/Gigabit connection to a host computer for debugging.Supports cascading control.
The devices can be centrally controlled via gigabit cascading, with a maximum of 8 units cascaded.Supports 3D display (load halved).
Achieves 3D display effects when used with a 3D transmitter and 3D glasses.Supports brightness and color temperature adjustment.
Frequently asked questions
What is the maximum pixel capacity of the KBS2000 Pro?
The maximum total load is 8.85 million pixels. Each Ethernet output supports up to 650,000 pixels, but multiplying that figure by 20 does not increase the total unit limit.
Does the KBS2000 Pro accept 4K video?
Yes. It has one HDMI 2.0 input and one DP 1.2 input and supports an input resolution up to 4096 × 2160 at 60 Hz. Input resolution and LED output loading are separate specifications.
Does it support HDR and Genlock?
Yes. The KBS2000 Pro supports HDR10 and HLG, 3D LUT color adjustment, and Genlock synchronization from an external sync source.
Can I use the KBS2000 Pro for a 3D LED display?
Yes, with a compatible 3D transmitter and 3D glasses. The specified load capacity is halved during 3D operation, so size the system for the intended mode.
Where can I download the KBS2000 Pro specification?
