Format a stick as FAT32, create folder
LG/installation/, drop the IPK in. On the
display: Home → Settings → General → Installer,
insert the stick, press OK.
Upload the IPK as a new application in SuperSign Manager. Assign it to the target group; the display auto-installs over the management channel.
npm i -g @webosose/ares-cli, register the TV with
ares-setup-device, then
ares-install --device tv im.ipk followed by
ares-launch --device tv com.imagesignage.player.
Skip the IPK entirely: any display with a browser can open lg.imaginesignage.app directly. Pairing, offline playback and rotation all work the same as the installed app.
