Configuration of TFT display

Help and Support Help
1

My Volumio setup consists of an RPi 5 with a horizontal TFT display and the following plugins: PeppyMeter, Now Playing, and Touch Display. Overall, everything works fine, but one thing keeps bothering me.
The seller of my display recommends adding the following settings to config.txt for Raspberry Pi:

max_framebuffer_height=1920
hdmi_mode=87
hdmi_group=2
hdmi_force_mode=1
hdmi_timings=480 0 30 30 30 1920 0 18 6 6 0 0 0 60 0 66280000 3
gpu_mem=512

Beginner question: Should I add this to userconfig.txt, or is it unnecessary since everything is already working?

If the screen is working as expected, then there is no need to add it.
if you wish to do it, only add it to /boot/userconfig.txt

Ok, clear. Screen is working fine, but I was wondering if setting the correct buffer parameters might be needed to avoid memory leaks or other issues in the long run.

I have an additional question: This display is connected via HDMI. During bootup, the screen is active (the backlight is on), but nothing is displayed until Volumio’s GUI starts. The boot process takes quite a long time (about a minute), and it would be helpful to see something on the screen: a logo, progress bar, or even the standard Linux startup logs.

Is there a way to enable this?

Then you need to add the entries, that makes the boot sequence visible.
But gpu_mem should be left out, as this can be set via the plugin. 512 is a bit excessive.

Where it should be added? Chatgpt tells me that I should modify cmdline.txt (remove ‘quiet’) - is it true?

Told you already in the previous post.

Maybe I understood you wrong, but it was the answer regarding LCD config. Now I’m asking about enabling visibility of bootup process. Should it be enabled in the same place? Can you give a command?
Anyway, shouldn’t be there (during bootup) any logo visible? In my case there is nothing up to start Volumio GUI

run as one command:

cat >> /boot/userconfig.txt <<EOL
max_framebuffer_height=1920
hdmi_mode=87
hdmi_group=2
hdmi_force_mode=1
hdmi_timings=480 0 30 30 30 1920 0 18 6 6 0 0 0 60 0 66280000 3
EOL

Reboot afterwards.

This point is clear and already solved by editing this file, thanks.
What about enabling visibility of bootup process?
