INPUT BEHAVIOR
Inputs E1, O1, E2, and O2 belong to the primary group, and inputs E3, O3, E4, and O4 belong
to the secondary group. All clocks within a group must be matched in frequency, but may be offset in
phase. If two groups are simultaneously active, the primary group will be displayed on the left hand
side of the screen with the secondary on the right. If only one group is active, it will occupy the entire
screen. If two groups are used simultaneously, it is absolutely critical that the input streams be
vertically synchronized /- 3 lines of each other.
Integer scaling of 1:1, 1:2, 1:3, and 1:4 is supported. Only exact 1:1, 1:2, 1:3, and 1:4 mappings
are allowed vertically. Video streams which are not exactly 2160, 1080, 720, or 540 lines tall will be
replaced with a test pattern and warning. Video streams with excessive width will be displayed with a
warning. Nonexact horizontal scaling will result in a horizontally centered image with unused display
area blacked-out.
Horizontal and vertical scaling are independent of each other, so non-square pixels are allowed.
This situation can be useful, for example, in a 3840*1080@240Hz scenario, if the host system is made
aware of the pixel aspect ratio.
If the input is detected as invalid or partially invalid, a test pattern or overlaid warning will be
shown on the screen to alert the user to the problem.
DE-Only timing mode is supported, with the HSYNC and VSYNC signals ignored internally.
Any duration of DE being low for more than 8 clocks is considered the end of the current line, and any
duration of DE staying low for more than 510 clocks is considered the end of the current frame. There
is no set limit for the maximum vertical blanking duration. The system does not require a consistent
blanking interval, variable blanking intervals are accepted.
ON SCREEN DISPLAY
An on-screen-display shows the selected panel, firmware version, and a realtime autoscaling
scrolling graph of the framerate of the most recent 253 frames, with minimum and maximum values
shown. The OSD is alpha-blended with the video stream and overlaid in the upper left corner of the
display.

blanking intervals are
