Display scaling
I am running a Pi2. I have bought a 7"inch non touch screen 1920x1080. It has several inputs like HDMI.
I have connected by HDMI
But I can't get modbros scaled to this size. I have tried several drivers and also tried to adjust settings in raspi-config.
Is there somehere else a setting to scale it wel?
The modbros image is too big. Missing screen right under.
Edit : I guess it has to do with the hdmi handshake.. I will take some more time to investigate.
Hiho, I had the same issue with my 7 Inch Raspberry Pi 4 Touch Screen 1024*600 Raspberry Pi 4 LCD Display HDMI TFT Monitor for Raspberry Pi 3B+/4B Model. (https://www.aliexpress.com/item/4000959465945.html?spm=a2g0s.9042311.0.0.3c766c3756l22n)
I'm using a RSPI 3B and in the seller's item description, it was explained that I needed to modify the config.txt file in boot folder with the following code.
Code for 1024*600 7 inch toucscreen:
max_usb_current=1
hdmi_group=2
hdmi_mode=1
hdmi_mode=87
hdmi_cvt 1024 600 60 6 0 0 0It actually solved my issue… I guess for a 1920x1080 you may have to change the hdmi_cvt? (I do not master the config.txt file D: ).
Regards.
@Racoon Thanks for the tips…. ThatsThat's exactly what I have been playing with yesterday.
But unfortunately nothing changes.
The resolution and aspect ratio changes on the console (start up) also in the display menu you see resolution according the config txt.
But as soon it boots in the modbros screen it's too big.
I am in a dead end…
Could be the driver board is bad. OSD menu is not in the middle. Seen on YT the same screen and driver combo and the OSD is in there in the middle…
See images: image url upload was not working.
According to your screenshots, you have a 1024x600 screen or am I wrong?
You can try to use another HDMI driver from the raspberry configuration page. Personally I use the LCD7B-show.

You can check their code in this gitHub I guess: https://github.com/goodtft/LCD-show
Wish u luck.
Unfortunately nothing helps ☺️
And I guess it's 1024x600 Saw somebody on Banggood with that comment. While it was sold as 1920x1080
I flashed Buster with Desktop and everything works fine… it scales in full screen.
Every time the Modbros screen comes up it's just partially imaged.
@modbros is it possible to run modbros as an app in Buster??
Hi @Justdigit
which display exactly did you use?
and did you install a driver or just manually tried a few values in the config.txt file or raspi-config to fix things?
and yes, you can use MoBro on any device or OS that has a web browser :)
but you will have to setup and configure things yourself. have a look at https://www.mod-bros.com/en/faq/mobro/raspberry/diy-setup

It's this display set

And man you can call me a real Raspberry Pi display professional. I have tried dozens of resolutions manual in the config.txt
Changed HDMI_mode 87 so you can put in custom resolutions. Etc etc
Tried to read out edid. Maybe it's sending wrong info. But I couldn't read our it gave errors.
Only didn't mess with HDMI_timings.
But with every resolution I get the same issue as seen in the pictures.
The only thing that changes is the resolution of the “console” startup screen.
Well, I don't know that display and have never used it.
But one guy in the reviews mentions that the display does only have a native resolution is 1024x600 and not 1080p.
Did you already try the config.txt values that he suggested?
hdmi_force_hotplug=1
hdmi_group=2
hdmi_mode=1
hdmi_mode=87
hdmi_cvt=1024 600 60 3 0 0 0Also a heads up just in case:
If you go through the configuration wizard on our custom MoBro image and leave the default ‘HDMI’ option selected instead of ‘Manual configuration’ in the display step, the config.txt will be reset once you hit apply.
