Three-layer switching with preview
The VSP1121 lets an operator prepare a source on a preview monitor before taking it to the program output. Two image windows can be positioned over the background, with pixel-based scaling and picture-in-picture layouts. Transition duration can be adjusted for presentation changes.

Planning a presentation layout
Select sources from the two input groups, position the image windows and check the result in preview before using the Take control. The routing function can exchange Program and Preview roles, allowing a VGA projector workflow. Choose the listed output timing that matches the receiving display equipment.
Frequently asked questions
How many layers can the VSP1121 display?
It processes three layers: two configurable image windows plus a background. The two windows can be positioned over the background.
What is the difference between the input count and the layer count?
The unit lists multiple selectable connectors in two input groups and a dedicated background input. These source choices feed three simultaneous processing layers; the connector count is not the simultaneous window count.
Can I preview a source before showing it on the LED screen?
Yes. VGA preview is provided, alongside two DVI outputs for the downstream display system. You can check the prepared image before taking it to Program.
Which output resolutions are listed for the VSP1121?
The existing specification lists 1024 × 768 at 60 Hz and 1920 × 1080 at 60 Hz. Input resolution capability is described separately.
