    Hi everyone, and thanks for support.
    Sorry I’m a total noobs here… I’ve bought a Pi2 and put Retropie 3.0 with roms. Now I will connect it to a CRT VGA monitor 4:3, is possibile? I need to do something (part the connector: I’ve found one on Am*zon)?
    Thanks everyone!

    Hi.

    I’m also trying to make an arcade machine with an old CRT TV.

    You can use the composite output (in the PI2 integrated with the sound in the the Jack connector), you will need a special cable for it, be sure it will work with the PI before purchasing.

    For better image quality, I am trying to connect the PI to the CRT through the RGB connection in the SCART of the TV. For this I need a HDMI to VGA adapter and after that, a VGA to CGA downscaler to convert the 31kHz VGA signal to the 15kHz that needs the CRT TV. I have bought both in Amazon, waiting for they to arrive. When I had tried them, I will post my opinión…

    Hi, good idea, I use a PC with ATI ALl in Wonder with SCART RGB out by now, wich will be the best output for CRT in my opinion.

    For the Raspberry, I’ve take your second part (HDMI-VGA cable) but to use it on 4:3 1024*768 75hz monitor, I must change something? I’m a noobs, and I don’t know if it will wirk immediatly. On Raspian, I think we must change something for example.

    You are talking about a CRT PC monitor yes?

    If so I think that the hdmi to VGA adapter should be enough, it works at 31kHz, same signal as the given by this adapter.

    The first ítem of muy order is to convert the 31kHz signal to the 15kHz needed by the CRT TV.
