Snow Leopard & Digital Triple Head2GO Problems

[SourceChild]

I have a utility I use that hard locks the displays from responding to EDIDs. I'll try it with 10.6 and see if I can alleviate anything.

I will test my digital TH2Gs on each of my 07, 08, 09 machines with x1900, 8800, and 4870 to see if there's a combination that causes or corrects it.

What utility is that? That could be handy... what does this normally help you with?

Just to chime in, was it only Digital THTG or did somebody encounter the same thing with analog ones?

Not that I got the heat to upgrade but the performance increase of Nevs testing sounds quite impressive

The utility is a shell script which tells the video card to disregard the EDID being sent from the monitors. I then run an application called SwitchRezX which allows me to build the custom resolutions needed by the monitors or TH2G.

It should be noted though that I only have the scripts to access the x1900 and 8800 video cards and only through Leopard. I've been playing around with this today and feel like I'm going to default back to using a DVI black box even though I don't like extra hardware in the chain.

Results as of today using Snow Leopard:

2007 MP w x1900
4 displays each 1024x768 : (3072x768) + (1024x768) dual out
4 displays each 1280x1024 : (3840x768) + (1280x1024) dual out
3 displays each 1024x768 : (3072x768) single out
3 displays each 1280x1024 : (3840x768) single out

2008 MP w 8800
6 displays each 800x600 : (2400x600) + (800x600) dual out
6 displays each 1024x768 : (3072x768) + (3072x768) dual out
4 displays each 1024x768 : (3072x768) + (1024x768) dual out
4 displays each 1280x1024 : (3840x768) + (1280x1024) dual out
3 displays each 1024x768 : (3072x768) single out
3 displays each 1280x1024 : (3840x768) single out

All passed with no side noise. I also researched several articles online regarding this same issue. There have been reports of this however all testing seems to point to issues existing in hardware other than the TH2G.

I won't have access to a 2009 MP with a 4870 unit mid October as they are all out on rental. If others can test this config before then it would be appreciated.

Please note that I use the SwitchRezX utility to establish my resolutions before attaching the TH2G boxes. Also note that the Dual TH2G configuration is not recommended.
