gig-e washed out video problem

#1 Fri, 12 Sep 2008 - 05:39

So, today I got a dual 450 gig-e, with a rage128pro in it. I right away hooked it up to my LCD, and started it off an OSX installer, to see that the video was very washed out. Playing with tiger & panther screen calibration has done little, I can get it to the point where it's almost acceptable but not quite. I also put my radeon 7500 from my sawtooth in it with no luck.

If I use the DVI cable on the r7500, it goes away and is usable, but that not really preferable to me because I want to use my PC tower on this monitor at the same time (there is a button to switch from vga to dvi).

OS 9 also has horribly washed out video; haven't tired with dvi yet. On this screen in windows and linux on vga and dvi the video is perfect.

Any ideas?

VGA works fine on windows or other mac's?

I haven't tried that yet, I will with my wallstreet in a sec.

Also, for OSX, maybe it needs the ATi graphics drivers? I'm not sure...

it could be the connector on the video card not making a good connection for the monitor. they might need cleaned, or buy a new video card

Seeing as it happens on both cards with two different VGA cables, getting a new card doesn't sound like a good solution. I have a feeling that either my LCD is confusing OSX, or the lcd is getting confused by OSX's Vga signals .

LCD's get confused? 8-o

I guess they can? Really I have no idea; this is a fairly nice dell LCD that I've had no problems with in the past. What I think I just need to do at the moment is get a proper driver for either my Radeon 7500 or Rage128pro (or both) and see how that works out.

Alternatively I could use my CRT on the other desk, but, ew.

So if anyone knows where to get those drivers for OSX or OS9, hook me up.

I guess this would work?

Really I have no idea if it will or not. It requires panther.
