I have bought a Raspberry Pi 7" touch screen, and it seems to work fine.
When the boot process is running, the normal Linux boot messages appear on the screen - but after the screen is filled, it seems to continue to write below the screen. As if the screen is "underscanned".
LINES environment variable says
LINES=48. Counting the number of lines visible on screen, I get to 30.
lcd_rotate=2 disable_overscan=1 dtparam=i2c_arm=off dtparam=audio=on enable_uart=0 dtoverlay=vc4-kms-v3d
ACTIVE_CONSOLES="/dev/tty[1-6]" CHARMAP="UTF-8" CODESET="guess" FONTFACE="Terminus" FONTSIZE="8x16" VIDEOMODE=
What should I do?
The screen resolution is 800x480. The problem does not go away after the boot process. I have to type
stty rows 30 to make it look okay.
