VMS04400 HDMI 2.0 Matrix Switch 4x4 with Scaler

Functions:

• True matrix switch to distribute 4 HDMI sources to 4 HDMI sinks (e.g. TV, video projector, AV receiver, capture card).
• Switchable down-scaler for conversion from 4K to 1080p for a Full HD display
• EDID management for targeted control of maximum audio and video formats

Functionality

The matrix switch allows any assignment of input signals to the outputs. Thus, one input signal can be distributed to up to 4 outputs, 2 input signals to 2 outputs each (or source 1 to one display and source 2 to 3 displays), etc. A common application is to connect a TV, video projector and sound system at the same time.

EDID SWITCH Modes:

1. 0000 1080P, Stereo Audio 2.0
2. 0001 1080P, Dolby/DTS 5.1
3. 0010 1080P, HD Audio 7.1
4. 0011 4K2K30_444, Stereo Audio 2.0
5. 0100 4K2K30_444, Dolby/DTS 5.1
6. 0101 4K2K30_444, HD Audio 7.1
7. 0110 4K2K60_444, Stereo Audio 2.0 SDR
8. 0111 4K2K60_444, Dolby/DTS 5.1 SDR
9. 1000 4K2K60_444, HD Audio 7.1 SDR
10. 1001 4K2K60_444, Stereo Audio 2.0 HDR
11. 1010 4K2K60_444, Dolby/DTS 5.1 HDR
12. 1011 4K2K60_444, HD Audio 7.1 HDR
13. 1100 COPY OUTPUT 1
14. 1101 COPY OUTPUT 2
15. 1110 COPY OUTPUT 3
16. 1111 COPY OUTPUT 4

These settings allow you to force higher formats that not all of your devices support. A display with an unusual video resolution, Dolby Vision, HDR10+ or for 3D video can be used optimally if its EDID is copied (mode 13 to 16).

Scaler 4K > 1080p

If a source supplies Ultra-HD signals, the scaler can be switched on for display on an additionally connected Full-HD display. The original signal of 3840 x 2160 pixels then becomes 1920 x 1080 pixels. In other words, exactly one quarter. The respective refresh rate and colour information is retained. A Full HD display thus receives 1080p with 60 Hz if the output signal is 2160p with 60 Hz. This ensures the best possible picture quality on the Full HD display. Ultra-HD / 2160p is still displayed on the main display.

Other resolutions from the PC world such as 1440p, or other display resolutions such as 720p, are not supported by the scaler. If a Full-HD display or projector does not show video even though the downscaler is active, please check if it supports 1080p. Some devices are limited to 1080i, or do not manage 24 Hz or 60 Hz.
