Arduino Digital Picture Frame - VGA?

Projects General Guidance
1

I'm using my Arduino Uno to make a Digital Picture Frame. I want it to read images from an SD card and display them on the screen in a slideshow. While the coding is something I can figure out myself, I need to know how to connect the Arduino and the screen. I am using a screen from a laptop and since I would need to get an adapter for that, I figured I'd go for a VGA adapter and try to figure out how to connect the Arduino to VGA. I've looked at adapters but there are few and are either too expensive or require more knowledge about how it works than I have.

What I'm asking:
Is there a way to connect the Arduino to VGA in a way that would allow me to display color images to the screen?
And if not VGA, is there other, possibly more simple, ways to get the image from the Arduino to the screen?

I'm looking for a solution that wouldn't cost a ton of money. If I had the money I would just buy a Raspberry Pi.

Didn't Google turn up anything for you? I started a project like this last year, never finished. But a search on something like "VGA pinout" led to signal information.

None of the projects I saw, used an "adapter". The VGA signals were produced in software and presented on output pins, translated by a simple transistor/resistor circuit to VGA signal levels.

I did google it, but most results were either about parts that no longer are available or didn't have the features I'm looking for.

You didn't say what features you're looking for.

Here is how to do it but you are going to lose some functions

Hi

Best way to do that and keep your coast low is to use two Arduino s one for the VGA and the other to do your stuff like this project

This is very useful. I appreciate it.
