@popcornmix, @timg236, @6by9, any idea?
Do you have the same problem if you use a normal Raspbian image rather than installing through NOOBS?
@neuralassembly - Some info on the displays might help the list of experts above. What make & model of display, default resolution, maybe even the EDID file from the troublesome display? Did you try pressing key '2' in NOOBS to change to hdmi_safe mode?
I tried the Raspbian image, and the same problem happened (i.e., no rainbow square, etc).
So, it would be a problem of Raspbian, not that of NOOBS.
Thank you for your suggestion.
Please answer @procount's questions:
What make & model of display, default resolution, maybe even the EDID file from the troublesome display? Did you try pressing key '2' in NOOBS to change to hdmi_safe mode?
And I'll add my own - have you tried the other HDMI port?
Does adding hdmi_safe=1
to config.txt make a difference?
My display with trouble is as follows.
UPERFECT 7inch 1024x600@60hz https://www.amazon.com/dp/B07CNNP9LN/
I summarize the situation.
*Pi 4 B with NOOBS 3.2.1
No problems with 1024x600 resolution.
*Pi 4 with NOOBS 3.3.0
NOOBS installation page is not shown. The rainbow square and boot sequence are not shown. Only the Raspbian desktop with 1024x600 resolution is shown. "hdmi_safe=1" makes the situation worse. Even the Raspian desktop is not shown. Two port (HDMI0 and HDMI1) give the same result.
*Pi 3 B+ with NOOB 3.2.1 and NOOBS 3.3.0
No problems with 1366x768. I don't know why the resolution is different from that of Pi 4.
When I try to install Raspbian to Pi 4 with NOOBS 3.3.0, I noticed that my display does not show anything.
When using with NOOBS 3.2.1, it has no troubles.
Therefore, I finished the installation using another display, and then I re-connected Pi 4 to the display with trouble.
It still does not show the rainbow square, boot messages, etc. However, after finishing the boot, it suddenly shows the desktop of Raspbian.
I think that there might be some trouble of the firmware of NOOBS. Are there any solutions?
