Video Output
The VX, GX and Pro ranges of Disguise media servers come with a range of possible output configurations. They can be configured to output a combination of DVI, 3G-SDI, HDMI, and Display Port signals by installing the correct combinations of VFC cards.
It is also possible to use the IP-VFC card to output 12G-SDI and ST 2110 video signals However, today these cannot be mixed with other VFC card types in the same server. Please refer to TA-42 for more information.

Notes
[1] Port 1 and 2 are dedicated to ST 2110 mode, and Ports 3 and 4 are dedicated for SDI mode when using SFPs.
[2] When in ST 2110 mode, a redundant SMPTE 2110 video signal using Port 2 can be enabled in the event that the video signal from Port 1 goes down, using SMPTE 2022-7 for packet-level redundancy.
[3] Resolutions:
- 4K DCI - 4096 x 2160px
- UHD - 3840 x 2160px
- 2K DCI - 2048 x 1080px
- Full-HD - 1920 x 1080px
- HD - 1080 x 720px

Bandwidth Calculation
We recommend using a bandwidth calculator to ensure that the number of pixels, bit depth, chroma subsampling, and frame rate are within the specification of the video interface that is being used, and are also within the specifications of the VFC card. A useful bandwidth calculator (not produced by Disguise) can be found here: https://tomverbeure.github.io/video_timings_calculator.
