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 ?
