Set 1280 x 720 resolution RPi Bookworm

frits.erasmus

I have an old Sinoteq TV measuring 5780mm x 3250mm screen

The closest resolution I get in the options is 1024 x 728. This causes images to show stretched
I am running MagicMirror on it showing images

How can I set the resolution to 1280 x 720?

VERSION_ID=“12”
VERSION=“12 (bookworm)”

I tried editing the “/boot/firmware/cmdline.txt” file and added

“video=HDMI-A-1:1280x720 vc4.force_hotplug=1” in that file.

When the RPi starts up the TV echoes res = 1280X720 and the splash screen perspective is correct.
As the Magic Mirror starts the same popup from the TV appears with Res = 1024x768 and when my image shows on screen, they are stretched (I am also viewing the screen with VNC and that perspective is correct)

Is there a place in MM2 where I can set the resolution to 1280x720?

Thanking any pointers in advance

@frits-erasmus you can try adding

electronOptions:{ width:1280, height:720},

in config.js, before the line

modules: [

@sdetweil

Thanks sdetwell, but that did not do the trick.

Just want to make sure this is what you suggested I do?

BTW: I have the TV vertical so I tried w1280 h720 and w720h1280 and neither made any difference

:-(

sdetweil

@frits-erasmus ok, you didn’t say vertical
let try this. electron might have saved something

stop MagicMirror

cd ~
rm -rf  .config/Electron

edit typo note dot in front of config

then start MagicMirror again w config set to
height:1280, width :720

@sdetweil said in Set 1280 x 720 resolution RPi Bookworm:

rm -rf .config/Electron

Sorry sdetweil ,

That did not make any difference.

@frits-erasmus bummer that all I’ve got for potential solutions

I found this

so lookup the wlr-randr command

man wlr-randr
or
wlr-randr --help

and I guess you would set it in the script that launches MagicMirror

I will try that tomm,

Thanks for your feers anyway.

Am am giving up!!!

I am just going to buy a screen that conforms to the Raspbian software

Thanks for all the help

frits.erasmus

Thanks for trying to help me, but I have given up now.

I will just buy a monitor that conforms with standard RPI Raspbian OS
