Joe- I have two identical IBM monitors, both work perfectly on a PC with VGA output, and one (by now I'm not even sure which one) worked perfectly with the first FFV2 board (I only ever tried one, because, after all it worked). I think I agree that the sync signal from the FFV2 is bad in some way. I made up a duplicate in wire of the 9 to 15 pin adapter according to ICD's diagram, and then actually disconnected the horiz and vert sync lines with minimal effect on the monitor picture. I'm going to try to borrow a scope this weekend to see if I can see what's acutally coming out those lines. Incidentally, you are aware of the variable capacitor you can adjust on the board to control the frequency aren't you? Also, the ICD Prefs program on the floppy that came with the board will let you adjust the horizontal frequency from about 50hz to about 80hz. I hooked up a 1084 to the RGB ports so I could watch what I was doing while adjusting that. All these things have had an effect, but not solved the problem. I'll keep you updated. Dick
