HDMI resolution problem

Refer to my posts on Element14 Forums: http://www.element14.com/community/thread/18205?tstart=0

Have you tried the help wiki?

http://www.raspberrypi.org/phpBB3/viewtopic.php?f=5&t=5851

Instuctions for others who may be experiencing the same issue with a TV and the Raspberry Pi:

1. Install a fresh image

2. start-up the Raspberry Pi and let it set itself up (normal set-up)

3. After you have gone through normal set-up:

a. Log-in as a normal user (debian image: pi)

b. Type the command: "sudo nano /boot/config.txt "

c. Press enter

d. Type in: "hdmi_drive=2 " [exactly as it is here]

e. Then press crtl + o

f. Press Enter

g. then press crtl + x

4. Restart using the command: " sudo shutdown -r now "

That gets the Raspberry Pi to register the TV as a HDMI device. You now have sound! For different resolution:

5. After you have gone through normal set-up:

a. Log-in as a normal user (debian image: pi)

b. Type the command: "sudo nano /boot/config.txt "

c. Press enter

d. Type in: "hdmi_group=1 " [exactly as it is here]

Press Enter

Type : "hdmi_mode=x " where x = corresponding number of resolution mode. See: http://www.raspberrypi.org/phpBB3/viewtopic.php?f=26&t=5851

e. Then press crtl + o

f. Press Enter

g. then press crtl + x

6. Restart using the command: " sudo shutdown -r now "

Now you have desired resolution and Sound!!!

Happy Raspberry Pi...ing

I hope this solves your problems

Hi Fergus

Thanks for posting on how to set up the hdmi screen. It worked first time for this (very) old man. Now I can see text on the screen, it was to small before your post!

Best regards

John

Hi,

I've just tried this. I set hdmi_group=1 and hdmi_mode=19 but that had no effect. I then tried hdmi_goup=2 and hdmi_mode=0x8 but that killed it and I had to start again with a new image.

Maybe I could change the settings on the TV but there are no options that I can find to do so. Does anyone know anything about Panasonic Viera's?

I ran into the same problem. Changed to 4:3 on the picture size using the TV remote. It was like magic . . .

Kev,

Also: Can you tell us if your TV is registred as a DVI device or HDMI device?  If yes, then follow the instuctions I posted above.  If no, then you might not be putting in the right commands or putting them in wrong.  All commands DO NOT have spaces.

Then:

You have to check whether or not your TV supports that resoultion.

See this link on how to do that:

1. Run “tvservice –m CEA” to give a list of CEA supported modes.

To do this, you must first change your directory to: /opt/vc/bin  (to do this enter command in terminal: "cd /opt/vc/bin")

then type: "tvservice –m CEA" (or ./tvservice –m CEA if it doesn't work)

then the Raspberry Pi will show a list of supported formats.  Use http://www.raspberrypi.org/phpBB3/viewtopic.php?f=5&t=5851 to get the commands of the supported format. Once you find the supported formats,

Thanks for the reply Fergus. I followed your instructions and found that mode 19 is supported (at least I think it is, the left of the screen is not visible so all I can see is:

          mode 1: 640x480 @60Hz, progressive

          mode 2: 720x480 @60Hz, progressive

          mode 3: 640x480 @60Hz, progressive

ative)  mode 4: 1280x720 @60Hz, progressive

          mode 5: 1920x1080 @60Hz, progressive

          mode 6: 720x480 @60Hz, progressive

          mode 7: 720x480 @60Hz, progressive

          mode 17: 720x576 @50Hz, progressive

          mode 18: 720x576 @50Hz, progressive

ative)  mode 19: 1280x720 @50Hz, progressive

          mode 20: 1920x1080 @60Hz, progressive

          mode 21: 720x576 @50Hz, progressive

          mode 22: 720x576 @50Hz, progressive

Thanks Peg, but when I do that the image is still cropped
