I'm having trouble getting an older MAG monitor (MX21F) to sync properly with a Geforce 4 ti 4400. The MAG will not even display vanilla VGA with the GF4. It reports an unregistered u-mode and occasionally the screen will flicker and I came make out some garbled display. I know the MAG is working because it will sync/display fine on my "backup" pc, which uses a Geforce 256 DDR. The MAG will display all the same reso/refresh combos with the 256 that fail with the GF4. Both adapters are using the latest 45.23 dets. I even swapped the older Geforce DDR into the newer PC and the MAG works fine there as well. So the problem appears to be with the Geforce 4 ti 4400. This adapter works fine with 4 other monitors I can throw at it though. I am using the standard VGA connector although the MAG also has 5 BNC connectors which I am getting a cable for this week. Anyone have any thoughts or ideas regarding this issue?
