Orangepi 4 LTS - no HDMI output

miguelRozsas · Published in 2022-9-1 23:00:17

Hi,

Running debian bullseye, uptodated.
When connect to a regular computer monitor, using HDMI-HDMI cable, no converters it show the image just fine.
When connect to a TV phillips 50", using HDMI-HDMI cable, no converters it show the image just fine.
But, when connect it to a TV Samsung 55" model Un55ru7100g, using HDMI-HDMI cable, no converters the TV did not detected input signal !
When I connect a raspberrypi 3B to the same Samsung TV, using the same HDMI-HDMI cable, no converters the TV show the image just fine.

I already changed HDMI cables, no change.
On Samsung TV there is no adjustments/controls I can change regarding HDMI ports.

The phillips TV is at my home where I setup orange to work as a kiosk displayed corporate messages.
Them I bring the orangepi to work place where there is a Samsung TV on the wall and it didn't detect input signal.
I can't use the raspberrypi 3B because it has only 1G RAM (versus 4GRAM on orangepi4) and it have trouble to run the media show thing.

What can I do to get a video signal on Samsung TV ?
