LED walls can use the right HDMI resolution #
Fix stretched content on Kramer and Oxygen LED walls; ordinary TVs stay at 1080p
18 Sep 2026
AdSpace TV v0.2.15.
LED walls no longer stretch ads into 16:9.
On some LED processor chains (Kramer / Oxygen), the Pi used to lock onto 1920×1080 even when the wall wanted 1920×960. The picture then looked stretched. You can now pick the correct HDMI mode on that one Pi. It is saved on the device and reapplied every time the kiosk starts. Ordinary TVs keep the usual 1080p picture — this setting is not baked into the flash image.
The on-device info API (:7224) now shows the live resolution, what the display prefers, and whether a custom mode is in use.
To set a mode on one LED-wall Pi:
make display-mode PI_SSH=pi@adspace-{serial} MODE=1920x960 OUTPUT=HDMI-A-2
To go back to the display’s preferred mode:
make display-mode PI_SSH=pi@adspace-{serial} CLEAR=1
If the wall does not advertise that resolution, the Pi leaves the picture alone.
