The Comp2DVI is an open-source (CERN OHLv2) device, designed for 240p – 1080i) retro gaming signals. This device has been tested, but we’ll still verifying it’s performance. MAKE AT YOUR OWN RISK!!! This page will updated when it’s 100% verified. The gerbers, as well as the Eagle design files can be downloaded here: http://retrorgb.com/assets/dvi/COMP2DVIv2.0-2019-04-02.zip
This device is powered by USB and has a DIP switch for the built in low-pass filters, tailored to each resolution. I’d expect in most cases you’d need the LPF on, but as a rule, you only want one LPF in any chain. I suggest starting with it off and try toggling to see if it removes noise.

Other Cables & Accessories
If you’re keeping the Comp2DVI close to your capture card for the least amount of signal loss, you’ll want some short cables. I also like to have a cable tie, to help with strain relief when a coupler is used:
