The size depends in how many quality / filesize you want. Emulationstation will scale the image to fit screen so you can use any resolution you like.

If you want to make a theme for 16:9 screen then do your bacground at a 16:9 resolution, and if you want to make your theme for 4:3 screens then use a 4:3 resolution.

List of common resolutions: https://en.wikipedia.org/wiki/List_of_common_resolutions

I recommend to you 1920x1080 or 1280x720 for 16:9 and 1024x768 or 800x600 for 4:3.

Regards.

Not a bug. Due to RPI sdl2 backend. We have sdl2 environment vars to change scaling etc.

@BuZz thanks. I'll try them all. Hopefully one of them will fix the problem.

@dankcushions said in Default HDMI mode can get you an (undetected!) slow performance on Raspberry pi...:

it must be your tv, then. libretro advanced tests is running at 60 fps, so if your tv is running at 50hz, with v-sync on you would be getting a stutter. anyone with a tv running at 60hz (which retropie does fine for me and most) should not get such an issue.

I have a Philips BDM4065UC/00 monitor, but that's a bit my point:
the default setting is 1920*1080 running at 50Hz. so If I don't realise that and change it, I get a poor performance...

to save configuration settings you should use https://github.com/retropie/retropie-setup/wiki/Configuration-Editor

Alright...never mind. Fixed it again. You are definitely right Buzz. Seems that my permissions keep changing or something.

I was able to fix the resolution not switching by inputting the sudo chown command followed by the ls command in putty. Without restarting my pi I went into each system runcommand menu and adjust the resolution settings.

Try integer scaling in the retroarch menu (select-x).

Ok have the audio working now. Last issue I have is that my usb Retro NES remote is all messed up. ie, b and a buttons are switched, select is starts. This causes issues when I cannot hold select and start to exit game. The remote works fine in other rom games except the NES. I have tried setting up several time in the input game pad set up and all worked fine on that

@Ashpool said in Can't get retropie 4.1 to boot in 720p:

. Is it possible to activate such a function here (please ignore if this forum actually is already warning the user about it) ?

It is activated, but the warning was probably shown to @RickyTan, your reply was later.

@zipfixer i don't really understand this rebooting thing, but the way to change aspect ratios for some/all systems is via https://github.com/retropie/retropie-setup/wiki/Configuration-Editor

note: this is only for libretro ("lr-") emulators, which are basically all the defaults for each system. for n64.. depends which n64 emulator you are using.

@PetroRie It won't affect shaders, which control this setting independently.

Thank you!

Also post support questions to the support category. Moved.

@Xyb0t said in Performance boos due to lower resolution??:

@dankcushions Well, i understand that scaling might not mean a lot, but rendering i guess will take it's toll??

they're the same thing. you can't 'render' a NES game in a higher resolution than 240x224 (or whatever it is natively). a higher render resolution just means it's scaled to that by the GPU. same with psx, etc.

(with shaders it becomes different)

How can i test for myself? Is there some form of on-screen FPS counter that i can switch on?

select + x to get to the RGUI. settings > video > show fps counter.

@rohini143

You should be more careful where you get your information from because you linked to a website which is awfully fishy.

@courtney

You realize that telling people to go to a website, let alone yours, to download a paid app, like DraStic, for free is piracy, right?

Reported.

@drasticd123

Stop repeating what other people said.

@t-prime
So, while I haven't begun with setting up my project, i still want to ask to be sure, as I'm quite new to all of this... (°_°). To keep the "fully working" hdmi, I can still follow the tutorial by adafruit (https://learn.adafruit.com/running-opengl-based-games-and-emulators-on-adafruit-pitft-displays/pitft-setup) and use their script, but I'll have to answer NO once I'm asked as you described and change the .txt file, right?

@Carbooja no. see http://commonmark.org/help/ (Three backticks for code blocks)
