I seem to have inherited 3 Mitsubishi HL7965KW-SG monitors. I've never touched anything of SGI's before and I bought a 13W3 Adapter to convert to VGA. I am noticing that they all flicker. I have read that I might need a Fixed Frequency card or another card that does something with Sync on Green. I need some good ideas and money is an object here. Unfortunately I understand it to only a limited extent and I am looking for resolution. Explanation is good, but resolution is what I am looking for. Thanks to all in advance!!!
