1920x1080 on Samsung 1080p TV

[davidtkhayes]

I am trying to use the Pi as a solution for displaying a website at work. I am new to this and unfamiliar with a lot of the settings, although played with some with no success.

I have the Pi (latest model) connected to HDMI input on 32" Samsung TV that can do 1920x1080 resolution.

What parameters do I set to force 1920x1080? It chooses 1776x952 in the settings, kind of an odd number

Second question: The only function of this unit it to display a webpage, can I set Pi to autorun the web-browser and load the home page each time it is turned on?

thanks for any help

You are in 1920x1080 HDMI, but we default to avoiding the border as many displays overscan the input so you don't see the edge pixels. You want disable_overscan=1 in config.txt (or use raspi-config).

Finally getting to address this.

I edited config.txt to include:
# uncomment this if your display has a black border of unused pixels visible
# and your display can output without overscan
disable_overscan=1

This made no difference and I am still showing 1776x whatever and not going to te\he edges of the TV screen

I also tried:
# uncomment to force a specific HDMI mode (this will force VGA)
hdmi_group=0 (tried 0 and 1)
hdmi_mode=82 (forces 1920x1080 60Hz)

And neither of these made any difference either.

Something I am missing?

Question 2. How do I start the web browser when Pi boots? do that automatically and go to a specific home page?

thanks for any help

Have you checked to see what modes your TV supports?

Use this command to check the CEA modes (Group 1)

Code: Select all

/opt/vc/bin/tvservice -m CEA

Use this command to check the DMT modes (Group 2)

Code: Select all

/opt/vc/bin/tvservice -m DMT

Use this command to see the current state.

Code: Select all

/opt/vc/bin/tvservice -s

You could use the LXDE autostart file to start the browser when the Desktop starts up. Which page the browser displays would be a browser home page setting.

I edited config.txt to include:
# uncomment this if your display has a black border of unused pixels visible
# and your display can output without overscan
disable_overscan=1

Did you reboot after the change?
Are you using NOOBS?
Run

Code: Select all

vcgencmd get_config int

and report output. That will show if you've entered disable_overscan correctly.

My bad....further down in the config.txt file was a whole section under 'NOOBS' something or other that had all the same settings and were overriding the settings we were putting in at the top of the file

Display resolution fixed.

Second issue also ressolved but found a Pi geek to help. Installed Chromium browser and used command line with the --kiosk option and the web address to autostart the program upon reboot.

looks like a great solution and thanks everyone for the help

Can you elaborate on how you got Chromium to start automatically, please?

[Hootis]

I have the same question....

Can you explain how you were able to launch Chromium automagically?

I need to launch in kiosk mode with a default home page. I would prefer to launch from the command line and not load the GUI.

I'm a total noob....any advise appreciated. (But especially detailed and correct advise! Lol)
