Technical issues Composite to VGA

I'm working on a project. As part of that, I would like to go from my NeS (original toaster) composite video to a VGA monitor. Dell M922 monitor.

I bought a $20 Composite to VGA converter. No matter how I adjust it, I can't get it to work. I get vertically scrolling hosizontal rainbow colored lines.

The monitor works fine fine when connected to a Dell pc.

The NeS Composite out works fine when I go direct to a crt television.

My guess is that the ***** converter is no good?

Any suggestions?

    Thanks. That's why I am assuming that the converter is the problem here.

    For this project, I may end up removing this monitor and swapping in a CRT television. Thanks.

    Yeah definitely, I assume you already know but that light gun game needs a 15khz tube like a CRT TV to work anyway.

    I'm not sure a simple "adapter" can get you from RCA to VGA (Analogue to Digital) ... without power.

    To get perfect converting, I would think that you need a plug-in converter box that has inputs and outputs. (Probably $20 to $30 on Ebay for a mini-converter ... or if you have 5 weeks, on Ebay from China for $12). That would 100% do the trick.

    I'm using a powered converter box from Amazon. Composite/S Video in, vga out. Unfortunately the 15hz Vertical Sync seems to be off.

    That should work.

    Then again, its possible you have a defect on that output. It's common.
