The Comp Cleaner is not a scaler!!! It simply routes the analog signal to the analog pins on the DVI connector!!! Visualize it exactly as if it was a Comp-to-Comp device, just with a different connector on the output side for interfacing with capture cards and displays’ analog inputs. Please read this page for more info:
The Comp Cleaner is an open-source (CERN OHLv2) device, designed filter 240p – 1080i YPbPr component video signals for use with digital devices, such as flat-screen TV’s and capture cards. I’d someday like to see a Comp2VGA version that’s identical, but with a male VGA output connector, instead of the DVI; This will allow more flexibility to your setup, depending on your target capture card or device.
This device has been tested and seems to work well at all resolutions. The gerbers, as well as the Eagle design files can be downloaded here:
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.

DVI-I Cable / Connector
This can connect to your capture card via a DVI-I cable or coupler. Make sure whatever your connection is using has the analog pins, otherwise it won’t work!
DVI to BNC: Coming soon
DVI to RCA: Coming soon
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:
