2play Posted August 17, 2023 Share Posted August 17, 2023 Hello to all, I am using an HDMI switch. I have noticed that TinkerBoard Armbian, displays fine the UBOOT text/logo but after that, the HDMI shows no signal/image If I connect the HDMI cable directly from the board to the monitor all is ok. What would be the reason or setting to be changed so TinkerBoard HDMI port can output display either case (hdmi direct to over a hdmi switch) tx in advance 0 Quote Link to comment Share on other sites More sharing options...
2play Posted August 22, 2023 Author Share Posted August 22, 2023 Do you believe its board related (tinker) or OS? Its the only board with this behavior. None of the Pi Boards have problem to display to HDMI via HDMI switch (same exact setup) Ill check also RockPro64 and revert. Ill try when time allows a Linaro release but if i recall well i had same problem Anyone can test over HDMI switch (mine has 3 intputs to 1 output) 0 Quote Link to comment Share on other sites More sharing options...
2play Posted August 25, 2023 Author Share Posted August 25, 2023 OK Ive tested same hmdi switch with my RockPro64 Armbian setup and i get no video also. the moment i put the hdmi directly form the board to the monitor hdmi signal goes through! So there must be or U-boot related or some driver... So if of interest maybe this will be replicated and fixed by the pros here 0 Quote Link to comment Share on other sites More sharing options...
