Blackscreen after changing the resolution in the Retropi - Part 2

dsquared

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.

@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.

@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.

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