TVOne has developed a new UltraHD multiviewer called the 1T-MV-8474. 16 different fixed layouts can be used to show up to four separate sources in windows, at the same time.
Seven inputs are featured on the product: DisplayPort (x2), HDMI (x4) and VGA. The DisplayPort interfaces support UltraHD up to 60fps, while the HDMI caps out at 30fps. Seven independent stereo analogue inputs are also built in, as well as a single scaled HDMI output (UltraHD at 30fps).
Audio can be switched separately from the HDMI stream, via a digital Toslink and eight independent de-embedded analogue audio channels.
Control is accomplished through a web UI, RS232, RJ45, IR remote or via the front panel. TVOne is selling the product now.
