Have you played around with the clamp st and clamp sp settings in the menu of the convertor board? Unless you get these settings perfect for your monitor then the picture is always going to look crap.
Tried this today and had no luck, not a difference at all unfortunately.. Still had the smear across the screen BIG TIME, especially green
Still thinking that it's the clamp settings as the pictures that you posted look like it. They can be a real bitch to get right and one setting effects the other. My Daytona USA conversion was a bitch to get right, lots of patience is required. I've done a few other LCD conversions and they were pretty much just set the clamp settings to those shown on the youtube video, but the Daytona USA was completely different. Thinking that RFM might be a similar bitch to get the settings right on as well.
If no good, maybe just buy one already done? http://lockwhenlit.com/products.htm
LOL that is exactly the one I have, dongle was bought from him, but I bought the 8200 cga converter, and I bought the lcd bracket from him aswell
