Hey, iv used google with no luck, so far all solutions use some kind of hardware, so i was wondering if someone here knows a way to output the resolution on a crt arcade monitor. Thanks for any help.

I can through DPI/GPIO or with a HDMI2VGA. In both cases, you'll have to use super resolutions as the raspberry pixel clock is very limited.

isnt hdmi2vga a piece of hardware? because im looking to achieve this without hardware, thanks

It can, through composite or gpio.

It can, through composite or gpio.
Do you have a webpage or info how to hook it up and configure it with the GPIO?

You need Gert VGA 666 at least. Devices such as Retrotink are not anymore available for sale.

what part of without hardware,do you guys dont get?

The answer to your question is no.

The answer to your question is no.
:cheers: its that simple, thank you sir.

Probably because a PI just has HDMI, GPIO and USB. And among those 3, nothing natively outputs 15kHz without some (hardware) magic. So the question was probably bad.

All raspberry pi units to date have composite interlaced and later firmware progressive.

Yep, 240p from the built-in composite jack. So yes, Rpi3 can output 15khz without hardware. I think the OP is bailed on us though.

HDMI@VGA and VGA@Scart working!!!. Scart input R,G,B, and Sync.. connect to Arcade monitor, it might work, you then need to edit the cfg file. I didn't try it on the arcade monitor but it worked 15khz on the Scart tv, I think it will work on the arcade crt monitor as well. in arcade automat I have 15khz already from RPI3B + with Vga666. For me, it is easy to buy Vga666 and download the finished image, you need PinHP, RGB-PI, Regamebox, etc ...
Sorry my english ..

Fyi, though my answer includes hardware, the simplest solution ive found is to use a Jpac.
I've used GertVGA....shrug... its fine... but was missing a piece when I ordered it, so it took a long time to get it going. I've tried a few converters (but they were garbage... didn't save settings on restart, stopped working, etc). At some point I had custom firmware that let me output 15hz via composite (before that was officially possible) directly to an arcade monitor, but for some reason I didn't like that solution either. One day I plugged in my jpac and it worked fine. One and done.
Jpac is a known quantity, easily available and has other value as well. Unless price is the absolute determining factor, I'd consider it the obvious option.
