Raspberry Pi3B+ and TS921 Sender card from Linsn
I’m trying to get a Pi3B+ to work with the sender card TS921 (TS901) from Linsn. I have connected the HDMI port from the Pi3+ to the DVI port from the TS921.
Pi3B+ -> TS921 -> RV908 -> LED Screen. This is technically working.
But.. I have a test LED Screen from 64x32 pixels. So I must play with the settings in the /boot/config.txt file to get the right HDMI output from 64x32 pixels.
In the config.txt file I can go as low at 320x240 pixels and I still have a part of the picture on my LED screen. If I go lower for example to 256x128 pixels the TS921 card stops receiving and I have no picture at all on the LED Screen.
I’m trying to figure out where the problems is, the Pi3B+ or the TS921.
So for debugging, I must know what is the lowest pixel mode to get from the HDMI port from the Pi3B+.
I can’t find this on internet therefore I ask here in this forum in the hope that someone can help me out.
Thanks for your answers. !
