Frequently Asked Questions

My display does not power on when I press the Power button on the KREMOTE

Some displays (for example, LG displays) must be configured to power on to the most recently used input for the display to turn on when the Strato leaves standby.

My display does not power off when I press the Power button on the KREMOTE

The HDMI CEC support in kOS 10.23.0 does not support the sending of power off commands to downstream devices.

I have enabled HDMI CEC on my LG display but the KREMOTE volume buttons are not working

LG displays currently ignore HDMI CEC volume commands.

HDMI CEC support for color keys.

Some display remotes include four color buttons. In kOS these buttons have been mapped to HDMI CEC commands as follows:

Blue:
- OSD: Activates the Kaleidescape Menu
- Playback: Activates the status overlay
- Equivalent to KEY_DISC_OR_KALEIDESCAPE_MENU IR command
Red:
- OSD & Playback: Operates as a "Back" button
- Equivalent to KEY_BACK IR command
Green:
- OSD: Activates the Kaleidescape Menu
- Playback: Activates the status overlay
- Equivalent to KEY_DISPLAY_INFORMATION_OR_MENU IR command
Yellow:
- OSD: Initiates a Library or OSD Store search depending on which place is active
- Playback: No effect
- Equivalent to KEY_SHOW_SEARCH IR command

NOTE: Some display devices may require additional settings tweaks to enable support for these commands. For example, on Samsung displays, you may need to enable the "Input Settings Plus" feature on the HDMI port to which the Strato is connected.
