The SE-500HD allows the user to place a logo on the video using the lumakey function. First of all,
create a 1920x1080 (16:9) logo against a black or white background on a laptop. Once the logo is
created, please follow the steps outlined as follows to insert the logo layer.
Note: If the logo is dark, choose a white background; if the logo consists primarily of bright colors,
choose a black background.

HDMI Input Ports
, HDMI Input 2 for example.
2. Press the MENU button to open the OSD Menu on the four-quadrant Multiview display.
3. In the Lumakey option, set the “ Lumakey Source ” to Input 2 .
4. In this example, the logo is against a black background so Black Mode is chosen.
5. Set the “ Cleanup Level ” to 10 if the background is in total black.
6. “ Transparency ” is set to 64 if an opaque logo is desired. Opaque logo can be created by setting
the “ Transparency ” parameter to 64. Semi-transparency effect can be generated by setting
