Re: STICKY: HOWTO: Create Custom HDMI modes

Hello, it is true that custom video modes (hdmi_mode 87) are not supported on RPI4? Thank you seems to work for some folks. But you might be better off with putting them into an EDID.dat file - under detailed timings section. But this is work in progress as it requires new firmware (which is still ...

Re: Multiple Monitors running separate images - Retropie

What is a 40-pin RGB TFT connected to HDMI port? There is no standard for interfaces in regards of no of pins, hence you will have to have a suitable A/D-board for your Marquee display (which has HDMI input from the host). You can run two displays from a single Pi, but you will have to write a scrip...

Are you using lastest firmware?
Have you added hdmi_enable_4kp60=1 to your config.txt?

Re: RPi4 Resolution Incompatibility

I think this is the one where the native mode was actually a detailed timing, so might need the firmware detailed timing fix to work by default. Quite possibly, but it seems odd that it is choosing a totally invalid mode. Unless it is that awkward fuzzy matching of the firmware's EDID parsing that ...

Re: Using a 4.3" Display with a RPi 3 or Zero

Your screen has a 24-bit DPI interface, means you can connect it to the Raspberry GPIO directly. Refer to https://www.raspberrypi.org/documentation/hardware/raspberrypi/dpi/README.md for more info. DPI will use nearly all (6-bit color) or all (8-bit color) GPIO, so you need to make sure there are en...

Re: Can the raspberry pie display the desktop in 4K P60 8bit-high FRC (10bit)?

Yes, HDMI is 24bit color (8bit each for RGB). As said, your display uses FRC, so your controller board will use any input. Maybe you should mention which hardware you want to use Btw: here is what a 4k desktop looks like https://www.raspberrypi.org/forums/viewtopic.php?f=63&t=244431&p=1491293#p14913...

Re: Can the raspberry pie display the desktop in 4K P60 8bit-high FRC (10bit)?

FRC is a controller board topic, so if your AD-board is able to drive a 10-bit (8bit+FRC panel) then the input is 8bit only.

To answer your question: yes.
