Retropie Resolution

[IR1S.retro]

Hello, Im new to retropie and the linux universe, I wanna make a retro emulation station and I wanna use a 1280x1024 monitor. Would retropie have any problems running that natively, and will I manually have to change it when I run retropie for the first time.

@ir1s-retro will run without problem, but you can set the resolution in 2 ways, with raspi-config booting up RetroPie, then going to retropie menu, choose raspi-config option, then choose Display Options, Resolution and choose the resolution of your monitor, go back, finish, reboot, yes.
If your monitor resolution doesn't show up, then use the other way, editing the file config.txt located in boot folder. Press Start, then Quit, Quit emulationstation, this action will guide you to terminal console, here you will write:

sudo nano /boot/config.txt

Then with arrow keys go down to:

#hdmi_group=1
#hdmi_mode=1

Delete # in both, and put the correct numbers in group and mode from the official raspberry pi documentation here

Something like this, seen in the link i share it, 32 is for resolution 1280x1024 but aspect is 5:4, dont know if that is correct for your screen:

hdmi_group=2
hdmi_mode=35

Once you have the corrects! save with

Ctrl + o 

( Vowel o), then Enter, and exit with

Ctrl+x

Now write

reboot

And i hope all will work fine, if you have a black square around your image, you will need to activate or deactivate overscan. That info you will find in the link shared. And the option is in the file config.txt that you edit.

@ir1s-retro ok ty, will i need to change it manually or will it automatically change it

@ir1s-retro manually with a keyboard, but if you boot up and all see correct you will not need to force the resolution of your monitor. So go to retropie site and install the official image. 😎🕹
