Problem with MPI4008
Just got my MPI4008 4inch screen for few days. http://www.lcdwiki.com/4inch_HDMI_Display-C
Everything work fine until installing the drive, after install the drive contex connect the display and raspberry pi 3b+ with hdmi and gpio, won't work, it only show up no signal.
So, I try the other way, by reflash the whole image leave the display setting to default ,only connect through hdmi without GPIO, and provide the display for individual power, it start to show up my computer sensor info.
I'm just curious where to fix the problem?
For additional information, I'm using a 5v1A power supply when I connect the pi and display with hdmi and gpio, will the power supply casue the issue?
Hi @normalHKAdrian
1A is probably not enough for both the Pi and the display. The official recommendation for a Raspberry Pi 3B+ is 2.5A
So I'd try again with a more potent power supply

@Seraksab Apologize for too much question, Can I use some kind of fast charge plug(QC~) that provide more than 5v1a for raspberry pi in this case to give it a try ?

In this moment, the only way to make it work are using HDMI connect the display with Pi and provide individual power for both devices.
Take me some time to get it work.
In case anyone wanna know, I plug my display after every setting are set and driver install, and now work perfect.
Glad to hear you were able to get your screen working :)
And thanks for posting the solution as well!
