Digikey BOM list in the attachment

Note:

This is NOT a scan doubler.

It fixes the flicker but keeps the original scan frequency unchanged.

Anyhow the adaptor works when connected to 15KHz video monitors such as BenQ, etc.

VGA cable is suggested to fit an EMI / RF noise filter (toroid/ferrite) on each end.
