I bought a touchscreen and installed the drivers for it, but now my hdmi doesn't work. I am currently running Raspbian on Raspberry Pi 4 model B.And I have a 3.5 inch tft screen.I do not no what driver I have. I got it through my terminal from the github. They gave me a command for the terminal to enable the hdmi but it doesen't work. They said that once I installed the driver it would disable my hdmi, but they said you could enable it by executing this command: sudo ./LCD-hdmi. The exact name of my screen is: MHS-3.5 inch Display. Can you guys help me?
sudo ./LCD-hdmi will run a script that uncomments the line
hdmi_force_hotplug=1 in Raspberry PI Config File which will force raspbian to use HDMI instead of the touchscreen. If you do this, you will have to comment the line
hdmi_force_hotplug=1 everytime you want to use your touchscreen instead of the HDMI. I hope this helps.
