Colorlight Z4 video processor and LED controller
The Colorlight Z4 combines video processing, splicing and LED sending for rental and fixed displays. The linked user manual specifies input up to 1920 × 1200 at 60 Hz, a total loading capacity of 2.3 million pixels and four Gigabit Ethernet outputs. Picture-in-Picture allows the secondary image size and position to be adjusted.
Check the hardware connections before ordering
The original listing and linked manual describe different rear-panel details. The listing names VGA and two single-mode LC fiber outputs; the manual identifies DP input and lists four Ethernet outputs plus HDMI monitoring. Confirm the actual unit revision and rear-panel photo before specifying these connections.
HDMI with loop, DVI with loop and two 3G-SDI inputs appear in both sources. The manual documents LEDVISION setup, scaling, cropping, screen mapping, brightness adjustment and color adjustment. Its input specification does not substantiate a 4K/UHD input claim.

Plan the wall using actual pixel dimensions, total load and output mapping. The manual describes zero latency of sending, which should not be read as a guarantee of zero delay through the complete video system. Match receiving cards and firmware to the confirmed hardware revision.
Frequently asked questions
Does Colorlight Z4 accept 4K UHD video?
The linked Z4 user manual specifies input up to 1920 × 1200 at 60 Hz. It does not support presenting this model as a confirmed 4K input controller.
How many pixels can Z4 control?
The documented total is 2.3 million pixels, with a maximum width or height of 4,096 pixels. Both dimension limits and the total pixel limit must be respected.
Does Z4 have VGA or DisplayPort input?
The original product listing says VGA, while the linked manual says DP. Confirm the actual unit revision and rear-panel connectors before ordering.
Are the Z4 fiber outputs confirmed?
The original listing describes two single-mode LC outputs, but the linked manual rear-panel table does not confirm them. Request a rear-panel photo and matching revision document if fiber output is required.
Can Z4 show Picture-in-Picture?
Yes. The manual documents PIP with adjustable image size and position, along with scaling and screen configuration through LEDVISION.
