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
