Re: Setting up HDMI output

Fri Dec 21, 2012 10:52 am

Can we have a little more detail?

The pi should output to hdmi automatically, what device are you trying to connect it to and what resolution is it's screen?

Generally what you will need to do is hook up the pi to your router while it is running via ethernet, SSH into it and run "sudo nano /boot/config.txt" to edit the settings, press ctrl x to save the changes and then call "sudo reboot" to restart the machine.

If you have an SD card reader you can edit the config.txt with a text editor on your lap/desktop computer.

I don't use openelec myself, RASPBMC is far more user friendly imo and has better support. You can also control it with your TV remote which is awesome.

I've had a problem, my desktop doesn't load properly, I just get the wallpaper.

But I have used multiple tv's in my house, and it's the same on all of them even after a reflash?

Re: Setting up HDMI output

Something weird is going on... maybe?

I received my new 512mb Pi yesterday and was using my 256mb one with a Raspbian SD card on a 1080p TV on HDMI until that, i used that SD card and the 256 Pi for testing a HDMI TO VGA box on a monitor that supports only support 1600Xsomething earlier, and now that I want to use my 512mb with that same SD Raspbian system again on my HDMI TV it only sets the resolution to 1280x720 @ 60hz (was running at 1080p before this / and with the 256mb Pi — i set up again the RAM split just in case and updated Raspi-conf and did an apt-get update+upgrade but the Raspbian was installed only a few days ago)

tvservice - m CEA or DMT returns "Group CEA/DMT has 0 modes:"
tvservice -d something.txt gives me nothing but an empty file...

tvservice -s outputs:
state: HPD high|DVI mode|HDCP off|composite off (0x120016), 1280x720 @ 60 Hz, progressive

Has my Raspbian system somehow memorized the low resolution from when it was connected to the other monitor? Would be weird i guess...
is it something related to some config of the 512mb version? (should have i refrained swapping SD cards between 256mb and 512mb models?)

edit: So i had already tried to turn if off and on again but not fully I guess... unplugging and replugging the HDMI cable on the Pi side (i tried on the TV side) made it be able to detect the CEA/DMT modes... and after a reboot it did set on the good (1080P) resolution. So, i guess everything's okay... (bit weird tho, isn't it?)

Re: Setting up HDMI output

This is my first day using the pi, and I am faced with a screen which is almost impossible to read it is about 60 rows x 240 characters. I am now faced with prospect of learning about screen resolutions trying to work out what i should put in the config file. I would not mind learning about this eventually. but within seconds of firing up the Pi.

Do I really need to learn about this on day 1. Surely it would not be to difficult for a Linux whizz kid to write an application called "cycle_through_all_suitable_screen_resolutions", which would allow me to select something I can actually read and then update the config file for me?

it does not display on HDMI. It workd on RCA video.

What is happening ? It worked on HDMI TV but ionly 2 o 3 times.

I use now the same setup but no HDMI signal

Anyone solved this ?

I search in forums and it seems to be a common problem

My Pi & LCD TV (model Cello TP-1907D with 16:9 aspect) are driving me crazy. I can see screen display using Composite or HDMI connection with config.txt having hdmi_safe=1. For the HDMI, I'm using a powered hdmi to vga converter. tvservice -m shows CEA but only mode=1 (i.e. VGA). I've run 'tvservice -d filename' followed by 'edidparser filename' and looked at the output. It showed near the end: HDMI:EDID preferred mode remained as CEA (16) 1920x1080p @ 60 Hz with pixel clock 148 MHz. So it looks like tvservice & the edid contradict each other. I've tried changing config.txt to have hdmi_safe=1 commented out and with: hdmi_drive=2,hdmi_force_hotplug=1,hdmi_group=1,hdmi_mode=16. But the display is blank. I've also tried hdmi_drive=2,hdmi_force_hotplug=1,hdmi_group=2,hdmi_mode=16 as the TV makers have told me that its VGA is 1024x768.

HDMI to VGA converters often report garbage in the edid. You may be better off with:
hdmi_ignore_edid=0xa5000080
and you are probably better off removing hdmi_drive=2, and I'd try config_hdmi_boost=4. But without a valid edid (which ideally would report 1024x768 as the preferred mode) you are down to guessing.

As you can see with raspbmc and defaults settings in /boot/config.txt I can only use 640x480 and 1280x720 resolution.

May I inspire to support 2560x1440 resolution in future with the RaspBerry Pi as well?

Any suggestion like using any still 'hidden' hdmi_mode etc. are welcome! Thx in advance,

I don't think this will be possible. [email protected] is the maximum we can drive.

Also 2560x1440 is not a standard CEA/DMT resolution.

If you really wanted to hack, you could set
hdmi_pixel_freq_limit=300000000
(effectively allowing overclock - behaviour not guaranteed).
And look here: http://www.raspberrypi.org/phpBB3/viewt ... 29&t=24679

But really without a scope and timing spec of the monitor, I think success is unlikely.

The Mode=4(i.e. 720p) for Group=1 on the Pi's config.txt did give a better display than using safe=1 (which presumably gives a Mode=1 i.e. VGA of 640x480). So I now have VGA of [email protected]

However, no matter how much I adjust overscan_right, it still leaves a 2cm border on the right. I guess that I'll have to live with that, unless anyone has a solution. Also, the TV speakers make an irritating crackle (like bad VHF radio reception). I 'll try to do some sound stuff to check it out.

Re: Setting up HDMI output

Hi, just to share my experience with the HP ZR2740W with 2560x1440 resolution at HDMI-DVI dual link cable:

I tried cusing the custom HDMI mode 87 by appending /boot/config.txt with

Code: Select all

#cvt_width=2560 (width in pixels)
#cvt_height=1440 (height in pixel)
#cvt_framerate=60 (framerate in Hz)
#cvt_aspect=3 (aspect ratio 1=4:3, 2=14:9, 3=16:9, 4=5:4, 5=16:10, 6=15:9)
#cvt_margins=0 (0=margins disabled, 1=margins enabled)
#cvt_interlace=0 (0=progressive, 1=interlaced)
#cvt_rb=1 (reduced blanking, only valid for 60 Hz vertical)

hdmi_pixel_freq_limit=350000000
hdmi_cvt 2560 1440 60 3 0 0 0
but the screen gets blank with that.
Although the mode was set correct and was automatically chosen as best value, this seems to overstrain the poor RSP with the huge required pixel frame rate regardless I tried the "reduced blank" option or not:

tvservice output without "reduced blanking":

Code: Select all

[email protected]:/opt/vc/bin$ tvservice -m DMT
Group DMT has 3 modes:
           mode 4: 640x480 @ 60Hz 4:3, clock:25MHz progressive
           mode 85: 1280x720 @ 60Hz 16:9, clock:74MHz progressive
           mode 87: 2560x1440 @ 60Hz 16:9, clock:312MHz progressive
tvservice with active "reduced blanking"

Code: Select all

[email protected]:/opt/vc/bin$ tvservice -m DMT
Group DMT has 3 modes:
           mode 4: 640x480 @ 60Hz 4:3, clock:25MHz progressive
           mode 85: 1280x720 @ 60Hz 16:9, clock:74MHz progressive
           mode 87: 2560x1440 @ 60Hz 16:9, clock:241MHz progressive
So, the HP ZR2740W can only be driven with 1280x720 resolution with the Raspberry Pi ... but that without having any need to adapt something in the /boot/config.txt. Well, I have to look for a Full HD native HDMI television/monitor to get the best out of the RSP and the video material, sigh. ;)

Re: Setting up HDMI output

Fri Feb 01, 2013 7:11 pm

@dom

The Mode=4 (i.e. 720p which presumably generates 1024x768 or 1280x720 - from looking at the hdmi-vga converter manual) for Group=1 on the Pi's config.txt did give a better display than using safe=1 (which presumably gives a Mode=1 i.e. VGA of 640x480). Would tvservice tell me which it is using?

However, no matter how much I adjust overscan_right, it still leaves a 2cm border on the right. Any ideas?

Hi!

I have a 32LG3000 monitor. I can't only get it to work with Raspberry's safe mode.

Could you please help me to get it to work in a better display mode (I want HD 720p)?

This is the output from tvservice:

Remove hdmi_safe as that forces it to VGA.
Options are here:
http://elinux.org/RPi_config.txt

hdmi_group=2
hdmi_mode=4

is VGA. You probably want:
hdmi_group=1

Re: Setting up HDMI output

Tue Apr 02, 2013 4:45 am

Hi, I'm from Indonesia, I've got my RasPi on Dec last year and I love it. First time I run it up I'm using my conventional CRT TV. Now I connect it to my 17" flat CRT monitor using a HDMI to VGA converter that I've just bought it on eBay. When I run it using Raspbian Wheezy, it's start to booting up but the monitor shows nothing except blinking indicator LED. When I reboot it (using Ctrl-Alt-Del), it rebooted and the monitor working well. I didn't find this when I run it using another SD card with Xbian, it's booting up normally.
Can anybody help me what should I do to fix it?

I am not sure if this has been brought up through this thread but I don't want to create a new one either. The current setup I have currently is:

My question is, when I run all the commands to find supported modes, is this for the TV or the receiver? Here is my output from all three:

edid_parser exited with code 0
Not sure why the preferred mode is CEA 2 though? Any thoughts why it would show that?

@stealthdeath

From the EDID spec: VESA ENHANCED EXTENDED DISPLAY IDENTIFICATION DATA STANDARD (Defines EDID Structure Version 1, Revision 4):
The display EDID data shall be defined with the understanding that the host shall evaluate and support the timing modes in the following order:
1 The ‘Preferred Timing Mode’ as defined in BASE EDID. See Note 2.
2 Other ‘Detailed Timing Modes’ in the order listed in BASE EDID. See Note 3.
3 Any additional ‘Detailed Timing Modes’ (priority is in the order listed) in optional EXTENSION Blocks to the BASE EDID --- See Note 4.
4 Any optional 3 Byte CVT Codes (defined in optional Display Descriptors) listed in BASE EDID or an optional Extension Block. See Note 5.
5 ‘Standard Timings’ listed in BASE EDID and in optional EXTENSION Blocks. See Note 6.
6 Additional Timing Mode Information: Established Timings I, II & III, Default GTF, GTF Secondary Curve & CVT. See Note 7.
7 BASE VIDEO MODE (Default VGA). See Note 8.
And your edid contains:
HDMI:EDID found preferred CEA detail timing format: 720x480p @ 60 Hz (2)
HDMI:EDID found CEA detail timing format: 1280x720p @ 60 Hz (4)
HDMI:EDID found CEA detail timing format: 1920x1080p @ 60 Hz (16)
HDMI:EDID found CEA detail timing format: 1920x1080p @ 24 Hz (32)

Which we are supposed to interpret as 720x480p @ 60 Hz is the preferred resolution of the monitor.
Your preferred resolution is presumably [email protected]0, but that only comes third on the "preferred" list.

I believe we are doing the right thing, but your TV has a poorly defined EDID.
