After installing the PVO software/drivers, once I'm past the PROM power-on test screen, the display goes black, but they aren't indicating "signal lost" or anything, so it is still outputting video, it just doesn't seem to be able to sync to it. Stopping and then restarting videod will cause the displays to sync for about 2-5 seconds, then go dark again.
Switching the 13W3->VGA cable into HV sync mode works on one of my displays, but the main one I usually use my SGIs with (a LG 19" 4:3 LCD) is not happy with SOG + HV sync, it shows everything really washed out.
Has anyone run into this problem before, and are there any configuration options/tweaks I can do to improve the situation? I realize I could probably get/build a sync stripper to take SOG out but it seems like I may be doing something else wrong.
Here's the output of gfxinfo:
