Solved [Screen bottom cut] resolution/aspect ratio

Sun Mar 18, 2018 11:25 pm

Sup everyone,
I have a pretty big problem..? I can’t modify screen ratio or is it resolution, even after install a knew OS.
Everything came after trying to get OpenGL to work and I find those lines on internet:
#hdmi_force_edid_3d=1
#avoid_warnings=2
Because I tried this on my two different PI3, none of them work correctly no more..
So my firs thing was removing "dtoverlay=vc4-kms-v3d"

This is a 5 inch display and it usualy works with those settings for my PI3B: https://www.waveshare.com/wiki/5inch_HDMI_LCD_(B)
max_usb_current=1
hdmi_group=2
hdmi_mode=87
hdmi_cvt 800 480 60 6 0 0 0
hdmi_drive=1

Actually, It is the display that need to be recalibrated at a resolution/ratio level!
Any Idea?

Just make really really again sure to again check again to see again if you mess your settings up..

max_usb_current=1
hdmi_group=2
hdmi_mode=87
hdmi_cvt 800 480 60 6 0 0 0
hdmi_drive=1

(my HDMI line was changing all the time.. So put settings and screen back on GPIO to start properly)
