6 inch 1080x1920 HDMI display - no picture

[rodizio]

Can somebody please give me a hint on what else to try to get this display working? I've been trying for several days now, been through all config.txt options, tried hdmi_boost, hdmi_safe and all the other options to no avail and in probably all combinations there are.

Tried it on Pi 2 and 3 with different distributions, Raspbian Jessie, Raspian Wheezy, OpenElec 6. Starting the X-Server or hello_video.bin on the Raspi also gives no Image and I could not see any meaningful log messages.

Definining a custom video mode and then using it also does not seem to make a difference. Tried 1920x1080 60Hz and also 1080x1920 60Hz. What's strange is, that when I don't have HDMI connected, I get the DMT mode 87 displayed in tvservice output, with the display connected it's not there anymore.

The display seems to be a bit weird in that it is a 1080x1920 display, on my Thinpkad X220 with Intel graphics I had to change it to landscape mode in Linux and Windows but apart from that it works fine.

Here is the output from tvservice and edid-parser on the Raspberry:

I'm not sure what else to try, or where to look further. Could it be just some weird hardware incompatibility or is it just that it's EDID values are weird?

[rodizio]

Well, I have converted the modeline the X-Server on my Notebook gave me to the config.txt hdmi_timings syntax:

Code: Select all

hdmi_timings=1080 0 118 4 118 1920 0 4 4 3 0 0 0 60 0 152900000 3

Does anybody know if these green lines are really sync issues? I'm pretty sure the timings are right. Atleast these are the ones where I got a working display in Debian on my Notebook.


What's weird is, that when I start the demo h264 with hello_video.bin, the image is good:


I have noticed in X, that the more black there is, the worse those green lines get. I.e. just the freshly booted up X-Window-System is okay, when I open a console window (which is black) and make it a little bigger, the green lines start coming again.

Hi there,

just noticed this question here as well

Well EDID data were generated by some keen engineer based on the data from the display technical literature (data sheet). By nature, timing data have minimum (min) - typical (typ) and maximum (max) values. Usually typical values were used when generating timing values.

Nevertheless, it's possible to use min to max - means anything in between - as well.
Without having access to the display data sheet you will end up in some try&error probing of the 'right' (there are no real right ones, there are some that are better, others are worse) values.
You've made it to here, so no you need to adjust some of the timing data. Resolution is fixed, so this leaves you some parameters to play with.

As I've mentioned already, increase horizontal front porch and decrease horizontal back porch (i.e. by increments of 4). I've also suggested already to increase the clock frequency.

Hi Rodizio,

Were you able to make the display work properly on the raspberry pi 2? I believe I'm trying to do the same thing as you are. My display is a Topfoison TF60008A (1080x1920), and I'm using the HDMI board which was provided. If I use it connected to a Windows 8.1 via HDMI, I see it as a display, and the image is shown in portrait mode in the middle of the screen (lots of unused pixels on top and bottom of the screen). I can rotate it in Display settings of Windows, and the it's worknig properly in 1920x1080, When connected to a macbook, the screen is fully used, and also in portrait mode.

However, when connected to a raspberry pi2, I'm not getting any image. Tried various settings in config.txt, but nothing seems to work... Any luck on your side?

Thank you,
Lothar

[rodizio]

Just tried again, looks like something has been fixed in the firmware or so.

Maybe it's still of interest for someone, the following settings in config.txt are needed:

Code: Select all

max_framebuffer_width=1080
max_framebuffer_height=1920
display_rotate=3
hdmi_ignore_edid=0xa5000080
hdmi_timings=1080 0 118 4 118 1920 0 4 4 3 0 0 0 60 0 152940000 3
hdmi_group=2
hdmi_mode=87

Problem is just, that display_rotate makes the display super slow and tearing occurs with moving stuff like videos. Apart from that it seems to work though.

Thanks a lot rodizio. We were stuck with this problem since the past 2 months. Already ordered the second lcd screen from topfoison after the first one had a higher resolution than the limit of the raspberry pi. The second lcd works (6" 1920x1080) with the settings you mentioned.

However, the frame rate is very low compared to the rendering rates we get on a dual boot laptop with hdmi output with windows 10 or linux.

Do you have any further suggestions to improve the frame rate ?

PS: "Maybe it's still of interest for someone, the following settings in config.txt are needed:" -- your post brought our 2 month effort to a successful end yesterday. Never underestimate the power of a positive action
