Hi, I would like more information about the orientation of my 800x480 LCD screen,
My configuration in config.txt is this:
hdmi_force_hotplug=1
# uncomment to force a specific HDMI mode (here we are forcing 800x480!)
hdmi_group=2
hdmi_mode=1
hdmi_mode=87
hdmi_cvt=800 480 60 6 0 0 0
I put a circle 50x50mm in the correct width and the height becomes smaller can anyone help me?
PS: The file image was generated in 800x480 in the nanodlp settings with 800x480 resolution.
Thanks.

try disable_overscan=0 or disable_overscan=1 based on your current settings.

Still the same error the circle has 50mm, more when it is designed it is 50mm wide by 46.70 high!

I could not think of anything else causing black border around the display.

I'm using Slicer.js to slice the images!
Dot pitch (mm) 0.19
Width (px)
800
Height (px)
480
Diagonal size
7
Diagonal unit in mm
