ATi have their own component VGA to Component video adapter, but unfortunately they only mention a few old cards which it is compatible with and the page hasn’t been updated for several years (e.g. mentions Windows 98 & XP as compatible, but no mention of Vista/7), so it’s most likely a discontinued product. On the other hand, as some of their early cards had YPrPb support, there is a good chance their more recent cards still offers support.
I tried looking elsewhere, but am getting mixed results of how people get on with VGA to Component video adapters on ATi cards and none relating to the ATi card model (or similar) you have.
So unless someone else here tried one of these with the x200M, your best option to start off with would be to ask a few eBay sellers of this cable. If they can’t confirm, the only last option would be to get it and hope for the best.
Unfortunately, the product manual links for ATi’s own adapter are dead, so if you decide to get it, you’ll need to figure out if there is an option somewhere to enable YPbPr support. Alternatively, you can disable the “Hide modes that this monitor cannot display” option and try resolutions like 640x480, 848 x 480 and 1280 x 720 and 1920 x 1080 interlaced (all 60Hz, if available).
