NOTE: When network video display is selected, configure network video settings (including resolution) with SLASetEthernetVideoParameters_t.
NOTE: Video Recording and Snap Shot are only available for cameras that are being processed for telemetry or display output.

Display Resolutions

This table specifies support for display resolutions on 1500, 3000 and 4000. Grey cells marked N are not possible. White cells marked N may be supported in future releases.

Supported for network stream with Out=In, not a selectable resolution
3000 can not keep up with 1080p60 in -> 1080p60 out. Display will look fine with 1080p30 in -> 1080p60 out. Similar at p50. If output rate can not match input rate, it's best if the output rate is a multiple of input rate (eg. 2X in this example)"
1500 net stream limited to 1280x720, 3000 net stream limited to 1920x1080
SDI Genum part supports limited resolutions, 720p, 1080i, 1080p, 480i, 576i. See Table 4-4
Possible future resolution support
1024x768 HDMI output on 4000 is at 70 fps, not 60 fps
1500 and 3000 analog support only NTSC (640x480) and PAL (768x576)

Display Resolution Combination Examples

When camera, physical display and network display resolutions don't match, cropping, windowing and sometimes scaling are used as shown in the following examples.

HDSDI display behaves the same as HDMI (3000 only)
3000/4000 Network resolution is the maximum of the network and physical display resolutions

Display Limitations for 3000 and 4000

The table below shows valid (white) and invalid (grey) combinations for display on a 3000 and 4000.
The system will warn and disallow setting invalid combinations. A is any camera (0, 1 or 2). A and B are two different cameras.

3000: No Analog at the same time as HDMI or HDSDI. It is possible to display to both HDMI and HDSDI.
4000: No Analog. HDSDI is only through the HDMI to HDSDI converter. Select HDMI and HDSDI will be auto-detected if the converter is connected.
3000: Use PiP to display a 3rd camera (eg. Net0 = PIP(Cam 0, Cam 1), Net1 = Cam 2). Available with a 3000-AB plugged into VIN 0 only.
System only records configured network streams using the settings for that network stream
4000 with PiP doesn't support streaming A to Net1.
4000 with Blend only supports a single stream
4000 does not support 2-Up

resolution

Physical display resolution (Analog, HDMI or HDSDI).
Configure network display resolution with SLASetEthernetVideoParameters_t.
NOTE: For 4000, HDMI resolution will be as set. Network resolution will be the maximum of the specified Network and HDMI (if active) resolutions.
NOTE: For 3000, see Resolution Combination Examples above.
NOTE: For 1500, Analog will crop from the network display if network shows higher resolution.
