Resolution problem on Raspberry 4

[reinhardkrakow]

Hi,
I use a Raspberry Pi with a 5 inch screen. The resolution of the screen is 800x480.
When I try to draw a circle, the screen displays a flat circle.

As you can see the program detect a screen 800x600 but the screen resolution is 800x480.

Could you please tell me what is wrong.

Kind regards,

If I use a HDMI screen (1920x1080), the program displays a correct circle.

This could be an issure with raylib detecting display resolution properly

I was using OpenVG in the past. On the Raspberry Pi 4, this library is not supported anymore. On the previous version RPi 2 3 it was working fine. I try to find a replacement solution with Raylib.

Hi,
I have another screen 800x480 (4inch). this screen works vertically (width 480, height 800)
I change my program in the initialization by putting:

const int screenWidth = 480;
const int screenHeight = 800;

The program recognize now the screen:

INFO: DISPLAY: No graphic card set, trying platform-gpu-card
INFO: DISPLAY: Selected DRM connector mode 480x800 (480x800p@60)
INFO: DISPLAY: Device initialized successfully
INFO: > Display size: 480 x 800
INFO: > Screen size: 480 x 800
INFO: > Render size: 480 x 800

and work perfectly.
I do not know why?

How I can configure my first screen (5inh) to work like the 4inch with

const int screenWidth = 480;
const int screenHeight = 800;

Hi,
The nearest display format in raylib for Raspberry Pi 5inch display is 720x480.
I just add in the /boot/config.txt fife :
overscan_right=80 to reduce the width of the display from 800 to 720
