Black borders with disable_overscan=1

[sirvapesalot]

Hi,

I have disabled overscan from the menu as well as from /boot/config.txt. After I reboot, nothing changes and I still get black bars. Also have tried using overscan_left right top bottom but that doesn't seem to do anything.

[mitu]

Please add more info about your system, as detailed in https://retropie.org.uk/forum/topic/3/read-this-first.
If you disable overscan, then the other overscan_xyz settings have no effect. Can you post your config.txt ?

[sirvapesalot]

Hi,

Thanks for the response, here is the config.txt:

For more options and information see

http://rpf.io/configtxt

Some settings may impact device functionality. See link above for details

uncomment if you get no picture on HDMI for a default "safe" mode

#hdmi_safe=1

uncomment this if your display has a black border of unused pixels visible

and your display can output without overscan

disable_overscan=1

uncomment the following to adjust overscan. Use positive numbers if console

goes off screen, and negative if there is too much border

overscan_left=-5
overscan_right=-5
overscan_top=-5
overscan_bottom=-5

uncomment to force a console size. By default it will be display's size minus

overscan.

#framebuffer_width=1920
#framebuffer_height=1080

uncomment if hdmi display is not detected and composite is being output

#hdmi_force_hotplug=1

uncomment to force a specific HDMI mode (this will force VGA)

hdmi_group=2
hdmi_mode=58

uncomment to force a HDMI mode rather than DVI. This can make audio work in

DMT (computer monitor) modes

#hdmi_drive=2

uncomment to increase signal to HDMI, if you have interference, blanking, or

no display

#config_hdmi_boost=4

uncomment for composite PAL

#sdtv_mode=2

#uncomment to overclock the arm. 700 MHz is the default.
#arm_freq=800

Uncomment some or all of these to enable the optional hardware interfaces

[mitu]

Please provide the rest of the information asked.

[sirvapesalot]

Sorry, here is all other relevant info. Please let me know if you need anything else.

Pi Model or other hardware: 4
Power Supply used: CanaKit Raspberry Pi 4 Power Supply (USB-C)
RetroPie Version Used (eg 3.6, 3.8.1, 4.1 - do not write latest): 4.6
Built From: Pre made SD Image on RetroPie website, Berryboot.
USB Devices connected: SSD in 3.0 slot and keyboard.
Controller used: Keyboard

I did change from Critical to beta and installed the latest beta to attempt to get boot to SSD going without SD card.

@sirvapesalot said in Black borders with disable_overscan=1:

Built From: Pre made SD Image on RetroPie website, Berryboot.

Probably that's the reason why the default RetroPie config options are not applied. Try un-commenting the ovescan_scale option and reboot.

@mitu

Same issues after using overscan_scale=1 in config.txt. Is it recommended not to use the berryboot?

[mitu]

It's recommended to install the RetroPie image directly, using Berryboot is not the preferred or supported option.

[saccublenda]

In my experience disable_overscan=1 does not disable overscan (so ignoring the overscan_xy settings), but instead disables a default overscan of 48 pixels on top, bottom, left and right. So my suggestion is to set disable_overscan=1 and adjust the overscan_left, overscan_right, overscan_top and overscan_bottom settings until the image fits your screen.

[sirvapesalot]

@saccublenda Hi, I may be confused as I downloaded the retropie 4.6 image and directly from the site and put that on the pi 4 for the install. I do have the set disable_overscan=1 and have adjusted the overscan_left, right, top and bottom to several different settings and rebooted with nothing changing. I am using an HDMI to micro HDMI cable with a new IPS LED monitor. I may mess with it a little longer and if same just start over.

[saccublenda]

@sirvapesalot Just to be clear: in your /boot/config.txt you have

disable_overscan=1
overscan_scale=1

and changing overscan_left, overscan_right, overscan_top and overscan_bottom has no effect?

[sirvapesalot]

@saccublenda

That's correct, here is a copy of my latest config.txt after a reboot.

Do you think this has to do with updating bootloader to latest beta to try to test usb ssd 3.0 booting? Maybe I'll downgrade and give that a go.

[saccublenda]

The only substantial differences that I find with my config are the commented dtoverlay=vc4-fkms-v3d setting, and the hdmi_group=2 and hdmi_mode=58 lines that in my config are hdmi_group=1 and hdmi_mode=16.
Try to uncomment the dtoverlay line first, and if this does not work try to set hdmi_group=1 and hdmi_mode=16.

[sirvapesalot]

Same issue :( I do see a Welcome to GNU/Linux 10 (buster) or something similar when it boots. I'm not sure if that's related to the version you said may be causing the issue.

@sirvapesalot I’m out of ideas. Before trying to reinstall the RetroPie image directly without using Berryboot, you may want to try on another monitor/tv.

[sirvapesalot]

@saccublenda

I tried editing the /boot/cmdline.txt to remove the pi text and just show retropie logo, but this also doesn't work.

I think maybe it's because I used Andreas Spiess guide on " Boot a Raspberry Pi4 with an SSD to make it reliable and fast". It has to be either that or using the beta bootloader.

[saccublenda]

Yeah, follow the official documentation and you will be good.

[sirvapesalot]

@saccublenda thanks for the help 👍

[BuZz]

If you're using berryboot, that has its own config.txt

Berryboot isn't supported btw, and we don't provide berryboot images for the rpi4. I wasn't sure if you meant above you installed the standard image to test after.
