Re: Setting up HDMI output

Sat Apr 27, 2013 6:17 pm

I am trying to set up for VGA using and HDMI - VGA adapter and I understand I need to change the screen resolution. I am being really thick here but how you access the config.txt file? Mine appears to be locked so I can't change values. How do I unlock it? I am not sure whether I can simply trash it and create a new one with the new values - will that lose all the other settings it controls?

Hi

Code: Select all

sudo nano /boot/config.txt
will open the file in a editor. Make your changes then press Ctrl+x to exit and follow the on screen prompts to save your changes.

Thanks Paul. Worked a treat - i was beginning to despair. VgA monitor now running although still fiddling to get resolution to fit ( too big).

I have been struggling with 14" CRT and given up for now.

I have a SHARP HDMI TV model LC-24DV510K which is an improvement - colour and nearly fits.

When I run tvservice -s it says "state 0x12001a, 1920x1080 @ 60Hz, interlaced" this is not one of the HDMI options listed - I don't know whether this is a problem or whether it would be better to change to one of the other options listed.

BUT whatever I set the overscan_left to I still can't see the first letter on the line!! Any advice?

The GUI is ok except crops a little on the right.

You have to say what kind of monitor this is - HDMI or CRT old TV. My 14" CRT TV won't show first 3 or 4 characters in command line which is not too bad as you can guess, but then the GUI is all wrong sizes also - using a 24" HDMI TV which shows nearly all - only missing 1 character each side

Hi

Have you tried adjusting the screen on the CRT using the manual controls as they usually allow you to stretch and shrink the picture both horizontally and vertically.

Good information, I should have read it earlier for troubleshooting my sound over HDMI issue.

At the start of the thread it was stated not all HDMI modes are supported by the RPi.

Now I know how to find out which modes my television can accept, please point me to the list of which modes the RPi can output, thanks!

Thanks! OK, I did see that list, but something made me question for a moment whether it was a master list of all possible HDMI modes that exist, or those RPi support. I suppose the comments reveal the details.

Densely Yours,

But when i pug it on my raspberry nothing append. I dont event have the redlight of my signal booster coming up. I have try in the config file the option config_hdmi_boost=7 but still nothing.

Re: Setting up HDMI output

Fri May 10, 2013 7:43 pm

I'm using a HDMI to DVI adapter on a Dell 1501FP DVI monitor and can't seem to get the right resolution or aspect ratio. It seems to think I have a 16:9 display and a higher resolution than I actually do and ignores the hdmi_mode I set in config.txt.

What I've tried so far:
Initially I couldn't get any picture at all and the monitor would show "incompatible mode", even with hdmi_safe=1. Strangely what worked was, while hdmi_safe=1 was set, booting the Rpi connected with composite to a TV then switching the connection to the HDMI->DVI Monitor . This was somewhat annoying though because on a reboot it would show "incompatible mode" again and I would have to repeat this every time the Rpi restarted (even when ignoring EDID). At this point I had the following output from the below commands:
pi@raspberrypi ~ $ /opt/vc/bin/tvservice -s
state 0x120016 [DVI RGB full 4:3], 640x480 @ 60Hz, progressive

pi@raspberrypi ~ $ /opt/vc/bin/tvservice -m CEA
tvservice-client: No supported modes returned for group CEA in [vc_tv_hdmi_get_s upported_modes_new]
Group CEA has 0 modes:

pi@raspberrypi ~ $ /opt/vc/bin/tvservice -m DMT
Group DMT has 1 modes:
mode 4: 640x480 @ 60Hz 4:3, clock:25MHz progressive
I then decided to look at my EDID data
pi@raspberrypi ~ $ /opt/vc/bin/tvservice -d edid.dat
Written 384 bytes to edid.dat

pi@raspberrypi ~ $ /opt/vc/bin/edidparser edid.dat
Enabling fuzzy format match...

HDMI:EDID features - videodef 0x81 standby suspend active off; colour encoding:RGB444|YCbCr422; sRGB is not default colourspace; preferred format is native; does not support GTF
edid_parser exited with code -1
The parser failed for some reason (guessing it's because of the HDMI to DVI adapter). Nonetheless I kept this edid.dat and set "hdmi_edid_file=1" in config.txt

This fixed my restart problem. I no longer had to connect it to a composite TV on boot. I then tried fixing my resolution. setting hdmi_mode=16 did not work. I decided that it was probably best to connect another PC to the monitor without the HDMI->DVI adapter and get a real dump of the EDID so I did (the results are below)

I then transferred this edid.dat to the RPi and connected it to my monitor again with the HDMI to DVI adapter. Now my screen was showing a higher resolution but higher than my monitor is capable of and the aspect ratio was wrong, it thought the display is 16:9. a segment at the bottom of the screen was showing the top (where the raspberry logo is) and the right was cut off because it was showing a 16:9 image on a 4:3 monitor. the output of "tvservice -s" was now
pi@raspberrypi ~ $/opt/vc/bin/tvservice -s
state 0x120005 [DVI RGB lim 16:9], 1280x720 @ 60Hz, progressive
what can I do to get my monitors native resolution and aspect ratio of 1024x768p @ 60 Hz (4:3)?

hdmi to vga set-up dell

hi
i'm new to rpi and am having some trouble understanding and setting up a vga monitor, i have three monitors one microtek and two dells, i'm trying to get one of the two dells working. the microtek works right off the bat with no configuration well it works in low resolution.

i have one dell:

and the other dell:

monitorserial: 5W54034O0FEU
monitorname: DELL E171FPb
monitorrange: 31-80, 56-75

when i turn on the monitor the power light is orange, when i power my rpi on the power light turns green and i can see the back light on the screen no nothing else just a blank black screen , the rpi yellow light blinks for a good bit so i'm sure it is to the setup page.
i tryed configuring the /boot/config.text and i tryed editing the config.text in the boot partion
hdmi_safe=1
hdmi_force_hotplug=1
hdmi_group=2
hdmi_mode=16 1024x768 60Hz
hdmi_drive=2
config_hdmi_boost=7

i haven't been to the confederating page yet so the /boot/config.text isn't helping
maybe some one with a little more understanding of this can help me out.

Re: Setting up HDMI output

Sat May 18, 2013 1:02 am

this worked for me all i needed to change three lines :
# uncomment if hdmi display is not detected and composite is being output
hdmi_force_hotplug=1

# uncomment to force a specific HDMI mode (this will force VGA)
hdmi_group=2
#hdmi_mode=16 #works 1024x768 60Hz
#hdmi_mode=21 #works 1152x864 75Hz
hdmi_mode=36 #works 1280x1024 75Hz

# uncomment to force a HDMI mode rather than DVI. This can make audio work in
# DMT (computer monitor) modes
hdmi_drive=2

Re: Setting up HDMI output

Mon May 27, 2013 6:58 am

So, I am trying to set up HDMI on a Toshiba 19LV505C and I am getting no signal from the TV even with the config.txt having:

hdmi_force_hotplug=1
config_hdmi_boost=4
hdmi_group=1
hdmi_mode=4
hdmi_drive=2

The pi works through the composite on the Toshiba 19LV505C, and through the HDMI using the default config.txt on another TV. I have no idea what else I could do to get the HDMI to work on the Toshiba 19LV505C. Here is the EDID if anyone can help.

Re: Setting up HDMI output

Thu May 30, 2013 3:03 pm

I'm trying to get my raspberry pi to send video to a square monitor (http://www.samsung.com/us/business/comm ... UDBPLBB/ZA); my eventual goal is to use a network of raspberry pis to drive a video wall.

The monitor has the rather unusual resolution of 960 x 960. This doesn't correspond to any of the options that are already built in to /boot/config.txt, so I tried to manually change the resolution in this file. However, this doesn't work :(

Here's my edid file to help sort out why this happening:

Re: Setting up HDMI output

Awesome! This seems to have corrected my screen resolution problem. I added the line:

Code: Select all

hdmi_cvt=960 960 60
to my config.txt and my raspberry pi boots up in the right resolution. 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?

Re: Setting up HDMI output

Just starting to get the hang of the PI but strugling to get the HDMI output correct.

What ever I do I can not get the resolution correct on my Sony 32" TV.

Below is my EDID but I am not sure what I should set it to from that info. I want to be able to display a image full screen at 1920x1080 and for it to look crisp.

Is this even possible.

Thanks

Re: Setting up HDMI output

Mon Jul 01, 2013 9:29 pm

Is there a set of circumstances in which the settings in config.txt will be ignored on boot?
I have the Pi set up as a kiosk, using an older Dell monitor via HDMI-VGA converter. I have confirmed that the following settings work:
hdmi_group=2
hdmi_mode=16
I know these work because if I configure the pi this way on another monitor via direct HDMI, then swap cables, the display works correctly. At this point I can reboot and all will work well. Running edid confims that the VGA monitor will support DMT mode 16 just as it is set in the config.txt.

However as soon as I do a full halt or the system loses power, on a fresh boot the display does not work. If I swap cables back to the HDMI monitor, I can see via /tvservice -s that the display is set to CEA mode 4 despite the settings in config.txt.

I have tried various options such as hdmi_ignore_edid, hdmi_edid_file, avoid_safe_mode etc. thinking that for some reason the monitor isn't reporting correctly at startup, to no avail. Is there some other reason for the explicit settings in config.txt would be ignored? Or am I making some other simple mistake that causes the monitor not to work?

Hi,

I connect my Raspberry to a 7" monitor LCD via composite.
I changed my config.txt to configurer the ouput .
My config is:

disable_overscan = 1
framebuffer_width = 480
framebuffer_height = 234

Will these parametres be used if I connect my Raspberry on another monitor via HDMI?
Are parametres HDMI and composite independent ?

By looking through this, I found a link to http://elinux.org/RPi_config.txt where the discussion of modifying the file /boot/config.txt was referenced. If you are having problems with hdmi sound, this is where you will find the answer.

I bought my raspberry pi model a from element 14 at the end of May 2013. (It is now mid-july and the camera module just arrived). My preconfigured sd card came with the the hdmi drive setting commented out. So I was not getting sound coming out, and I was getting frustrated. Reading the elinux wiki answered that problem.

Hi there,

I'm trying to connect an Atomos Ninja as HDMI-output device. I was not able to get a picture, even though the edid-extraction showed, that it was supporting a lot of modes:

Did anyone ever had success with an Ninja connected to a RaspberryPi?
Any ideas what I'm doing wrong?
Here's my config.txt:

Code: Select all

# uncomment if you get no picture on HDMI for a default "safe" mode
# hdmi_safe=1

# uncomment this if your display has a black border of unused pixels visible
# and your display can output without overscan
disable_overscan=1

# uncomment the following to adjust overscan. Use positive numbers if console
# goes off screen, and negative if there is too much border
#overscan_left=16
#overscan_right=16
#overscan_top=16
#overscan_bottom=16

# uncomment to force a console size. By default it will be display's size minus
# overscan.
#framebuffer_width=1280
#framebuffer_height=720

# uncomment if hdmi display is not detected and composite is being output
hdmi_force_hotplug=1
# hdmi_ignore_hotplug=1

hdmi_mode=20
hdmi_ignore_edid=0xa5000080
hdmi_group=2
hdmi_drive=2

# uncomment to increase signal to HDMI, if you have interference, blanking, or
# no display
#config_hdmi_boost=4

# uncomment for composite PAL
#sdtv_mode=2

#uncomment to overclock the arm. 700 MHz is the default.
#arm_freq=800

# for more options see http://elinux.org/RPi_config.txt
start_x=1
gpu_mem=128

# disable_camera_led=1
Thanks for your help,

much appreciated,

SOLVED: hdmi_drive was obviously wrong, so setting it to one made the picture appear no the Ninja, hurray!
