Extron Expands Quantum Ultra II With Eight-Channel HDMI Cards
Extron's new eight-channel HDMI input and output cards double the channel capacity of its existing four-channel 4K PLUS cards for video wall processing.
Updated on Nov. 3, 2026 in Quantum Computing
Extron has expanded its Quantum Ultra II video wall processor line with the Quantum IN8HDMI 4K PLUS and OUT8HDMI 4K PLUS, eight-channel HDMI input and output cards. The new cards double the channel capacity of existing four-channel 4K PLUS cards.
Why it matters
The eight-channel cards allow larger video wall designs to fit into a single Quantum Ultra II chassis and lower overall system cost for integrators. The expansion strengthens the platform for installations that require high channel counts.
The cards support channel resolutions up to 4096x2160 at 60 Hz and custom widths up to 8K with full 4:4:4 color sampling, over a HyperLane video bus with throughput of up to 500 Gbps. Pricing and shipping timelines were not included in the announcement.
The players
Extron
Extron is a California-based manufacturer of audio-video signal processing, switching, and control equipment used in professional installations.
The details
The IN8HDMI 4K PLUS and OUT8HDMI 4K PLUS are fully compatible with other cards in the Quantum Ultra platform. Embedded audio from any input can be routed to the first output of any canvas, and embedded source audio can feed a Dante network when a Quantum OUT32AT is installed.

The Tech Race
The eight-channel cards extend the four-channel 4K PLUS line already in the Quantum Ultra platform, doubling per-card channel capacity within the same architecture. The move positions Extron to compete for large-scale video wall installations against rival processor makers offering high channel counts.
Integrators can build larger video wall designs in a single Quantum Ultra II chassis, potentially reducing hardware and installation costs. Installation teams gain eight channels per card instead of four, reducing the number of cards needed for high-channel-count displays.
The takeaway
Integrators planning large video wall projects should consider whether eight-channel cards can reduce the number of chassis and cards required. Compatibility with existing Quantum Ultra components makes the upgrade path straightforward for current users.
