Question What settings cause my Display to look like this?

Hi. I'm trying to set up a Zidoo Z9S for my mother's TV.
The colors are weird and I can't seem to find why, could anyone help me with my issue?

That's a "negative" image and looks just like roll of old-fashioned colour print film, in the days before digital cameras.

Check the menu settings on the Zidoo and the TV and see if there's an option to invert the colours displayed.

The Zidoo or TV might be running in CMYK mode, instead of RGB (if I've got my terminology right). Bizarre.
