Blackscreen after changing the resolution in the Retropi - Part 2

Re: Blackscreen after changing the resolution in the Retropi

Hello:

I am having the same problem as this earlier post. I am unable to change my screen resolution in raspi-config. Was a solution found?

Pi Model or other hardware: 4B+ 8GB
Power Supply used: Generic 5.1V 3000mA
RetroPie Version Used: retropie-buster-4.7.1-rpi4_400.img (updated all packages)
Built From: Pre made SD Image on RetroPie website: retropie-buster-4.7.1-rpi4_400.img
USB Devices connected: generic USB SNES controller & MS bluetooth keyboard & mouse
Controller used: generic (kiwitata) USB SNES controller
Error messages received: zilch
Verbose log (if relevant): N/A
Guide used: N/A
File: (File with issue - with FULL path): config.txt?
Emulator: N/A
Attachment of config files: https://pastebin.com/ECCpJe9z

How to replicate the problem: I started from scratch trying to create a retropie sd image. Downloaded Img from this site & created bootable card. booted first time, configured controller, enabled Wifi, updated the raspi-config script & all retropie packages and rebooted. I tried to change resolution in Retropie Setup. I had run tvservice -m DMT and received 10-12 viable 60 & 75 Hz settings - every one of them would result in a black screen after showing the initial Raspberry Pi colour palette and linux booting progtrssion. (BTW I tried changing the resolution before updating the raspi-config tool and retropie packages and the result was the same. When I restore the default resolution - I will not see the Raspberry Pi colour palette - so I know it will work..

Is this the working config.txt or the one that doesn't ? What resolution are you trying to set up ?

@mitu

The non working one am trying to set resolution at
DMT32 1200x960 60Hz 4:3
But I can not change the resolution to any of the viable resolutions returned by tvservice -m DMT

Hm, that's weird, 1200x960 is not a 4:3 resolution, you maybe meant 1200x900 ? You can set, in the config.txt file`

hdmi_force_hotplug=1
hdmi_ignore_edid=0xa5000080

so that the Pi ignores the EDID sent by the monitor. What's the output of tvservice -m DMT ?

You are right! now you see why I need to change the resolution :)

Just thinking can I change the following lines in the config.txt file from:

#hdmi_group=2
#hdmi_mode=85

to:
hdmi_group=2
hdmi_mode=32

This didn't work

Have you tried selecting the resolution from the Runcommand launch menu ? You can keep the default (I assume 1080p) resolution for the front-end and change the resolution just for running the games.

dsquared

@mitu
Thanks but I am fine with the resolution in the emulators. What I would like is to increase the resolution in everything else- command prompt, file manager, raspi-config script, retroarc config script & retropie setup script.

@dsquared Have you tried after switching resolution did you try the other port after a reboot?

mitu

@dsquared what is your default video resolution (i.e. without any modifications to config.txt) ? Isn't it 1080p ? - this looks like the largest resolution supported by your display.

dsquared

@mitu

Sorry - I have sizes reversed - I want to increase the size of text on the screen - so I want to decrease the resolution......... 1080 1920x1080 is the max resolution...

The check out this FAQ entry on how to do it, there's no need to change the resolution.

@mitu

Thank you! - The font was so small I couldn't see this option but it is corrected now.
