Raspberry Pi 5 - official announcement

To change the resolution, add to the end of cmdline.txt !file the following:

video=HDMI-A-1:"add_your_width"x"add_your_height"M@"add_your_refresh_rate"

Example for 1080p 60HZ resolution:

video=HDMI-A-1:1920x1080M@60

Also, don't forget to add in the end of /boot/firmware/config.txt file this line :

kernel=kernel8.img

Thank you for your quick response.

Unfortunately this doesn't work; I don't understand why.

When the Pi boots up and the fan is running at full speed, it displays correctly but once ES is started it is the wrong resolution.

sugarfree

@Slythief It should work. Can you post the cmdline.txt file? Do the games have the correct resolution?

Slythief

@sugarfree

The games work but not in 1920x1080, I have to go to a lower resolution so that the image does not overflow the screen.

cmdline:

console=serial0,115200 console=tty1 root=PARTUUID=24658be2-02 rootfstype=ext4 fsck.repair=yes rootwait video=HDMI-A-1:1920x1080M@60

@Slythief At this stage, I assume that an image would be helpful as I think different people are reading a different problem from your statements, including yourself. From your last statement, I am assuming this is actually an overscan issue, that you'd adjust on config.txt, setting overscan to 1 and adding overscan to it (negative or positive, depending on what you're observing).

Slythief

@pjft

Thank you for your answer, I will try! Will an official image be available?

@Slythief said in Raspberry Pi 5 - official announcement:

Will an official image be available?

at some point yes, when we don't know

Slythief

@ExarKunIv

I hope it arrives quickly.

I noticed that I was not the only one to have resolution issues but none of the proposed solutions worked.

Overscan doesn't work either, no matter the value nothing happens.

sugarfree

I think the overscan settings don't work at all in Bookworm right now.

Slythief

@sugarfree

Yes that's what I think

pjft

@Slythief Can you share a screenshot, though? That would be tremendously helpful. Thanks!

Slythief

@pjft

a TV screenshot to show what's happening?

pjft

@Slythief Yes. And a copy of your config.txt file while we're at it :)

config.txt: https://pastebin.com/ax7uKHeE

pjft

@Slythief Yes, this is overscan related.

set

disable_overscan=0

and then add

overscan_left=32
overscan_right=32
overscan_top=32
overscan_bottom=32

and see if anything changes.

Slythief

@pjft

Nothing happens unfortunately.

pjft

@Slythief Got it. Was reading up on it, seems to be an issue with Bookworm indeed. Sorry about that.

Slythief

@pjft

Well, is there another solution instead of going with Bookworm?

pjft

@Slythief Not on the Pi5, and not that I'm aware of. Unsure if you'd have a better experience installing Ubuntu, but I don't have any experience - nor knowledge - about that to share.

Slythief

Problem solved:

Add 1080p_audio.bin to usr/lib/firmware.

Add this line to cmdline.txt:

drm.edid_firmware=HDMI-A-1:1080p_audio.bin video=HDMI-A-1:1920x1080M@60D

Now everything works smoothly at 1080p.

1080p_audio.bin:

If you have no sound:

From Emulation Station -> Retropie -> Audio and choose the last option.Reboot.
