August 17, 20233 yr 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
August 22, 20233 yr Author 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)
August 25, 20233 yr Author 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
