tvONE CM-HDMI-4K-2IN – Dual HDMI 4K Input Module for CORIOmaster
Product Overview
The tvONE CM-HDMI-4K-2IN is a 2-input HDMI 4K module for CORIOmaster video wall processors. It accepts two HDMI inputs at resolutions up to 4K30, or one input at 4K60, and supports HDMI 2.0 and HDMI 1.4 standards along with HDCP 1.4. Resolutions up to 3840x2160 and 4096x2160 are supported depending on color format and frame rate. Compatible with CORIOmaster C3-540 and CORIOmaster mini C3-510 chassis (sold separately).
Product Description
The CM-HDMI-4K-2IN installs in any available I/O bay of a CORIOmaster or CORIOmaster mini chassis and provides two HDMI inputs with support for 4K UHD resolutions. In two-input mode, each input accepts signals up to 4K30 (3840x2160 at 30Hz). In single-input mode, one input can receive 4K60 (3840x2160 at 50/59.94/60Hz in 4:2:0 8-bit) using the HDMI 2.0 standard. The module also supports 4096x2160 (DCI 4K) at 4:2:0 at 50/59.94/60Hz. For standard HD and lower resolutions, both inputs operate across a range from 480i and 576i through 720p, 1080i, and 1080p at frame rates from 24Hz to 60Hz. Color space support follows BT.601 for standard resolutions and BT.709 for HD and 4K content. HDCP 1.4 compliance allows protected content from Blu-ray, cable, and streaming sources to be accepted without errors. The module supports both HDMI 2.0 (required for 3840x2160 4:2:0 at 50/59.94/60Hz) and HDMI 1.4 for all other resolutions, covering the full range of HDMI source equipment in professional and consumer AV environments.
