Re: [9fans] Re: Raspberry pi with a largish screen?

Thank you, this exact set of lines ends up being exactly right for driving my 
LG 27UK850-W at 1/4 resolution (native resolution would need some work put into 
the window system and fonts to be more comfortable). I don't believe I'd tried 
the max_framebuffer_* or hdmi_pixel_freq_limit settings before.

I'm using a Lenovo C32Q-20 with that config.txt and it works perfectly.

[9fans] Re: Raspberry pi with a largish screen?

[taylor . garry]

This is my whole config.txt:

[pi4]
kernel=9pi4
arm_64bit=1
[pi3]
kernel=9pi3
arm_64bit=1
[all]
gpu_mem=16
core_freq=250
enable_uart=1
boot_delay=1


hdmi_group=2
hdmi_mode=87
hdmi_cvt=2560 1440 60 3 0 0 1
max_framebuffer_width=2560
max_framebuffer_height=1440
hdmi_pixel_freq_limit=25000

It gives me a 2560x1440 screen with no black borders. That's on a Raspberry Pi 
4.

That is  with 9Front.

Hope that helps.

Garry
