So, my O2 displays 1440x900 on my HP Elitedisplay really well, however I know this display is not SOG tolerant. For some reason it won't display 1280x1024_60 well, the image is offset, probably due to CRT timings in the VFO.

Has anybody tried building a sync stripper as per the link below? I'm keen to try but have no electronics / board layout knowledge and don't quite follow how the board is suppose to be laid out. 

Instructables PS2 SOG

It would seem that this stripper could also apply to VGA in -> VGA out, stripping the sync signal from the green channel with the LM1881. I like the idea of placing a pot inline to adjust for variances between machine signal output. 

The parts are really cheap, the LM1881 is £2.60 on RSonline, the rest come to about £2 in change. 

Have time, have the money, just not the build know-how....

Actually, if there is already H+V sync from the O2, surely all that is required then is the diode and pot to change the voltage? (This clearly shows I know nothing about electrical circuits etc.! )
