How to set the native screen resolution

Michel

Both Crowpil OS and Raspberry Pi OS boot with 1920 x 1080 resolution. The native resolution, said by Elecrow is 1366 x 768, so there's an upscaling and small characters are difficult to read...
Did anyone change the resolution ? By editing config.txt in Crowpil OS ? Or by the "screen configuration" tool in Raspberry Pi OS ?
Regards,
Michel

I gave a try to change the screen definition.
Crowpil OS : Edit /boot/config.txt, comment the lines "enable_uart=1", "hdmi_cvt 1920 1080 60 6", "hdmi_mode=87" and add the line "hdmi_mode=39", reboot, the definition remains 1920 x 1080 but it's possible to use the screen configuration tool to get a 1366 x 768 screen. After that, the Pi panel becomes unusable because it's suited for a HD screen...
Raspberry Pi OS : Add the lines "hdmi_group=2" and "hdmi_mode=39" in the config.txt file, reboot, again the definition remains 1920 x 1080 but it become possible to use the screen configuration tool to get a 1366 x 768 screen. This definition brings a great comfort to your eyes.

We're sorry that the UI of the Pi Panel is only compatible with 1920 * 1080 resolution. Therefore, if you change the resolution of CrowPi L, the Pi Panel will not display full screen.

CrowPi L OS you can run "sudo nano /boot/config.txt" on the terminal
Modify the line "hdmi_cvt 1920 1080 60 6" of the main screen to "hdmi_ cvt 1366 768 60 6"
Save the changes and exit. Reboot CrowPi L then the resolution will be modified.

For me it works fine with the following entries in config.txt:

# uncomment if hdmi display is not detected and composite is being output
#hdmi_force_hotplug=1
hdmi_cvt 1360 768 60 6


# uncomment to force a specific HDMI mode (this will force VGA)
hdmi_group=2
hdmi_mode=87


# uncomment to force a HDMI mode rather than DVI. This can make audio work in
# DMT (computer monitor) modes
hdmi_drive=2

It is only hdmi_cvt 1360 768 60 6 because the figure must be divisible by 8.
