I got the 5B brand new, connected it to my monitor and thre's no image. The monitor works, the cable works. xrandr lists HDMI but no active monitor. Then I had a look at the layout but didn't find any schematic. Maybe I am wrong and it is connected correctly. But then again, why is there no image.

Thats true, 5's layout is different. There's schematics for the 5 pcb and they are correct. Very odd. Waiting for someone who got the 5B with a working HDMI.

I think you are missing something, or I am. Have a look at the HDMI pinout. Starting from the right in my picture, theres four differential pairs, they seem to be ok on the board. I added a piece of layout from another project for comparison. Then on the left, there's hotplug, 5V, some unused pins and the ddc lines. If you compare them to the actual 5B's layout, there has to be an error. They are connected like this: How can this be a working connection? Also, why are those lines routed differentially, with caps in the lines? And why are the ESD diodes not connected to them? I know it's barely visible in the image, but someone with an actual 5B should see that plain as day.

I tried a few images, but from what I see on the pcb it is a hardware issue, no matter the image. I hoped someone here might use an OPI 5B and shed some light, if their pcb looks the same with or without a working HDMI.

Hey guys, I just received an orange pi 5b, pcb says version 1.1. Unfortunately, the HDMI is dead, out of the box. No display is being recognized. The pi boots, though. Then I had a closer look at the HDMI connector on the board. I wonder if the HDMI ever works for anybody. The traces are connected in the wrong place, especially the DDC lines for monitor data and the hotplug detect is mixed up. The picture confirms that. The pin on the lef is supposed to be hotplug detect, but it routed like a differential pair and connects to a capacitor. The other trace of that pair is also in the wrong place. Can some of you confirm that? Does you HDMI work an a 5B rev 1.1?
