I am using 7 inch HDMI touch screen with Raspberry Pi 4. I am having below issues:
- I have connected the HDMI cable to the touchscreen and connected the mini hdmi to hdmi0 of pi. I have also connected the power adapter to the touch screen slot of the screen. During bootup, I can see the OS loading but after that I do not see the desktop and it keeps showing red color saying Not Support.
At this point, if I unplug and replug the HDMI cable, it then starts showing the desktop. I have double checked the HDMI cable with another monitor and the cable is fine.
During the usage, if I keep the Pi idle for around 5mins, screen starts showing blue color. If I move the mouse the blue color goes away and it starts showing the above red color screen. I believe this can be changed from settings but I am not able to find appropriate settings for this.
Touch is not working on the screen. Do we need to enable touchscreen from settings in pi.?
Has anyone experienced this type of issues with 7 inch HDMI touchscreen and raspberry pi 4. Can anyone please give me some ideas on how to resolve this. Please help. Thanks
