Re: Setting up HDMI output

Sun Jul 21, 2013 1:27 pm

I wonder if anyone can help. I can get RCA output to my Samsung Plasma tv, but no HDMI. When powered up and connected via HDMI I can select the source in the TV menu, but the TV displays "No Signal" (if the HDMI lead isn't plugged into anything, I can't select HDMI1, so there must be some sort of recognition between the Pi and the TV.

I ran the following:

Code: Select all

openelec:/usr/lib # tvservice -m CEA
Group CEA has 9 modes:
           mode 1: 640x480 @ 60Hz 4:3, clock:25MHz progressive
           mode 2: 720x480 @ 60Hz 4:3, clock:27MHz progressive
           mode 3: 720x480 @ 60Hz 16:9, clock:27MHz progressive
  (native) mode 4: 1280x720 @ 60Hz 16:9, clock:74MHz progressive
           mode 5: 1920x1080 @ 60Hz 16:9, clock:74MHz interlaced
           mode 17: 720x576 @ 50Hz 4:3, clock:27MHz progressive
           mode 18: 720x576 @ 50Hz 16:9, clock:27MHz progressive
           mode 19: 1280x720 @ 50Hz 16:9, clock:74MHz progressive
           mode 20: 1920x1080 @ 50Hz 16:9, clock:74MHz interlaced
openelec:/usr/lib # tvservice -m DMT
Group DMT has 1 modes:
           mode 4: 640x480 @ 60Hz 4:3, clock:25MHz progressive
openelec:/usr/lib # tvservice -s
state 0x12001a [HDMI CEA (4) RGB lim 16:9], 1280x720 @ 60Hz, progressive
openelec:/usr/lib # tvservice -d edid.dat
Nothing written!
I've amended my config.txt file to include the following:

Code: Select all

# Force HDMI even if unplugged or powered off
hdmi_force_hotplug=1
hdmi_drive=2
hdmi_group=1
hdmi_mode=4
And changed the value of hdmi_mode to each of the modes listed in the results of tvsevice -m CEA but ever boot up just displays the same "No Signal" error.

Does anybody have any ideas as to what to the problem is, or what to try next?

Edit to add - I first posted this in the Troubleshooting Forum - here is my original post detailing the full circumstances - http://www.raspberrypi.org/phpBB3/viewt ... 24#p391224

@eli
Try the boost option here:
http://elinux.org/R-Pi_Troubleshooting# ... VI_monitor
If that fails try hdmi_safe=1.

If that fails, try a different HDMI cable.

I cropped a video to 960 x 960 to play with omxplayer (which seems the right resolution when I play it on another computer); however, when I play it with omxplayer on my raspberry pi, it's highly distorted. Perhaps something like 960 px tall x 320 px wide.

Any thoughts on why it is so highly distorted?

Help!

I'm a school teacher and very NOOB!

The school just bought a 5 Lilliput 619A 7" Screens: http://lilliputweb.net/field-monitors/h ... /619a.html
and 5 Model B Pis with the Boot SD cards from AusPi technologies: http://www.buyraspberrypi.com.au/shop/r ... r-package/

The screens work great with a HDMI cable into my laptop. But with the Pi... "NO INPUT SIGNAL".

I'm afraid current posts here are going over my head... can anyone help?

Hi,

well, how to start?
If you don't see anything on the screen when connected to the Pi, it seems to not find a compatible mode for the screen.
So, what you need to do is to edit the config.txt. You could either do that by logging into the Pi via SSH, or you can just take out the SD-card and put it into a reader on your laptop. There you open the config.txt with notepad/textedit and comment out or add hdmi switches.
You'll find a comprehensive list of switches here: http://elinux.org/RPiconfig.
You should be able to still find an automatic mode by trying the switches:

hdmi_force_hotplug=1
hdmi_safe=1

If this fails, come back and read through the thread from the beginning. You will then understand much more of it, having already edited config.txt for the first time and will find a mode which works.

Cheers,

MatzeHali

Thank you so much... but you're not going to believe this.. but... I turned on and off again...and it worked.

Dang! The screen needed to be on first then boot up the Pi.

Sigh... what an afternoon.

Hi

Setting

Code: Select all

hdmi_force_hotplug=1 
In config.txt will fix that.

I hooked up my pi yesterday, and since installing Raspbian have had green bars flickering across my screen. They only show up on black (for example, I get them on the default wall paper, but only on the black, the red in the logo is as it should be.) It makes the terminal almost unusable which, as you can imagine, is a problem. I've tried all of the fixes I could find. Any advice?

At some point this information might move to a different place (e.g. elinux WIKI page) but for now I am putting it here and making it sticky.

Here is a list of all CEA and DMT formats (as of CEA-861 E and DMT V1 r12 respectively).

If you want to use any of these modes explicitly, set hdmi_group and hdmi_mode to the correct values in the config file. Note that NOT all modes are supported by the Raspberry Pi hardware (mainly the high resolution/high frame rate modes) and all explicit modes are subject to EDID* support of the monitor/TV.

If the file config.txt is not present or the output format is not set explicitly, the default output format is chosen as follows:

1. If the preferred format in EDID is supported, this will be chosen.
2. If the preferred format is not supported, then all the formats supported will be ranked according to some heuristics. The format with the highest score will be chosen.

If the chosen format is a DMT format, the default driven mode will be DVI. The user will need to explicitly set driving mode to 2 if HDMI output is desired. In DVI mode there will be no sound!

How to override the default format in config.txt:
1. Set hdmi_group = 1 (for CEA formats) or hdmi_group = 2 (for DMT formats)
2. Set hdmi_mode = x (where x is the code of the format of the respective group, see the list of CEA/DMT formats for details.)
3. If the chosen format is DMT, set hdmi_drive = 2 to enable HDMI output. (CEA modes are output as HDMI by default).

If you are unsure what formats are supported, set the output format to VGA 60Hz and then follow the instructions below to parse the EDID to find out what formats are supported. All executables are found under /opt/vc/bin.

1. Run “tvservice –m CEA” to give a list of CEA supported modes.
2. Run “tvservice –m DMT” to give a list of DMT supported modes.
3. Run “tvservice -s” to give you the current state.

Alternatively you can:
1. Run “tvservice –d <file>” to capture a monitor’s EDID.
2. Pass this file to edidparser. Run “edidparser <file>”.

edidparser outputs the list of formats supported in EDID include formats not supported in Raspberry Pi, and it will show you which formats are filtered out. At the end of the output it will show which format is chosen as default. edidparser is the internal EDID parsing code of Raspberry Pi with a command line front end.

Users are encouraged to post the EDID of their monitors (and the output for the parser), if Raspberry Pi chooses a default resolution which is not expected (or strange).
Please include make and model number when you post EDID online.

[Only for the curious]
The ranking of formats is based on a combination of resolution, refresh rate, whether the format is progressive/interlaced/native, and where it appears in the EDID.

See http://elinux.org/RPi_config.txt for information on editing config.txt

i'm sorry, but WHAT?!?!?! I'm a beginner and this is like reading ET heiroglyphics or something. Is there a Super-Ultra Beginners Version of this?

Try my configuration tool http://www.raspberrypi.org/phpBB3/viewt ... 91&t=52441 it makes things easy. Look up the native resolution of your liliput display and set it. Try force on, and force hdmi mode and lastly safe mode if it still doesn't work. Good Luck

have changed settings in config.txt to hdmi_mode=16 to change the screen resolution , however the tv still shows in 640x480 any help with this would be appreciated as i am a novice just starting with pi but knowledgeable with computers in general.

Just to be sure, you uncommented the line also right? There isn't a hash mark (#) at the beginning of the line is there? Otherwise would you mind posting the contents of your config.txt?

Hi all, so I've got my new pi setup with noobs and am using OpenELEC when I'm in xbmc it seems that the screens a bit too big can only see half the time and some of the side menu is missing. I've tried entering a few different combination from post 1 but am still struggling. My pi is connected to my Panasonic TX-P42V20B which values should I go for pleas.

I'm afraid current posts here are going over my head... can anyone help?

did you ever get a response that made sense and worked? I'm afraid i also don't understand ANYTHING they're talking about here :cry:
This is the entire point of NOOBS. Download NOOBS v1.3 from http://www.raspberrypi.org/downloads, install it onto the SD card as explained in http://www.raspberrypi.org/quick-start-guide, boot your Pi, then press buttons 1, 2, 3 and 4 in sequence until you see a display.

You should never then need to ever worry about it again.

Monitor on Standby

Sun Oct 06, 2013 4:34 pm

Greetings !

My /boot/config.txt reads like this -

hdmi_edid_file=1
hdmi_force_hotplug=1
hdmi_ignore_edid=0xa5000080
hdmi_group=2
hdmi_mode=58
config_hdmi_boost=4
disable_overscan=1

I generated the edid.dat on my ubuntu machine and transferred it here. I get the preferred mode as :
(prefer) mode 58: 1680x1050 @ 60Hz 16:10, clock:146MHz progressive

tvservice -s shows
state 0x120016 [DVI DMT (58) RGB full 16:10], 1680x1050 @ 60Hz, progressive

The monitor is on standby, it doesn't wake up, it doesn't show anything.
Could anyone please help. Please let me know if any additional information is required.

- Rajiv

You could have a problem with overscan.
Edit overscan varaibles in the bootconfig file.
Use "sudo leafpad /boot/config.txt" (or replace leafpad with nano if you prefer command line text editing) to start editing.
Try something like this

Code: Select all

disable_overscan=0
overscan_left=20
overscan_right=20
overscan_top=20
overscan_bottom=20
After you have saved the file, restart the system to view the changes.
You might have to adjust the overscan values again before getting it just right.

Since so many people are having major issues with display setup on Raspberry Pi I've decided to start a project to create a graphical display setup tool.
Graphical interface for Monitor Settings
The idea is to create something similar to the monitor setup in Mac/PC, a GUI for setting common things like resolution and overscan.
As well as providing a wizard that suggests what the user should change based on what his display problems are.

If you think it's a good idea, want to help or have any thoughts on how the project should be implemented don't hesitate to write something in the thread

Hello,

I would make every encoder Video HDMI to IP Lan, you could use the HDMI port as an input but not as output video?

Thank you. I only see a black screen. I do not have a config file to edit. Should I have that? If not, I wonder why it was not part of the download for Windows?
