I have an interesting problem and I was hoping someone could help.
Let me preface this issue by saying that I am currently running Lakka on an Asus Tinkerboard, and it is running quite well. Was just trying out some PSP Crisis Core, and N64 OOT which seemed to work well. I did my initial setup and install using a Toshiba LED monitor using HDMI.
Here is were it gets interesting. After getting all ROMS onto the SD card, I decided to move it to my older 40inch LCD Samsung. It would primarily be a black screen, and sometime flicker to a fuzzy screen, and then back to a black screen. I even got the menu to appear once. But since then I only get a black screen.
However, it works perfectly on my Toshiba LED monitor. I am using HDMI on my tinkerboard and HDMI inputs on both my devices. Both devices are 1920x1080. I have read about adding some various HDMI flags to the config.txt or boot.ini, but that does not seem to exist on the tinkerboard. Furthermore, I installed TinkerOS (Based on debian stretch) and the desktop and kodi appears fine on the 40inch Samsung.
Let me know if anyone has an ideas! I am fairly proficient with bash and a terminal so I can definitely try some stuff! Looking forward to getting this fixed.
The more reading I am doing the more I want to try setting: hdmi_force_unplug=1 config_hdmi_boost=4
However, I cannot find this “config.txt” the people keep mentioning. Any ideas on where I can find it?
