I have no problem running D3D games in Multi-monitor mode. OGL won't go (although I've heard with the TurboGL they will), but the D3D games I've tried have done fine.

And as far as disabling DH and rebooting...that isn't necessary. Just go to your display properties, and clear the "extend desktop to this monitor" checkbox. Then OGL will work without needing to reboot...

This is not a limitation of the G400 drivers, this is a limitation of Windows. I am sure there is a workaround with drivers, but AFAIK you cannot use multi display with two OpenGL cards in one system.

My complaint about dual-head is that I sometimes have to disable it entirely before playing a game (like the copy of Expandable that gets shipped with the card).

I'm not talking about going into Display Properties and unchecking the option. I mean having to go into Advanced, to Dualhead, and completely disabling the *#@*ing thing.

Never had to do anything that absurd when I had my pair of i740s.

Kruzin, I tried it with TGL, and no go. Have to disable the DH option totally.

C=64, great computer, but what you say about the disabling and all is maybe because it's a hardware function that has to be re-routed?

Just see it as installing a new piece of hardware in your PC. You'll have to reboot after that to let Windows see you installed something new.

When using DH, every head uses 16Mb memory.
When disabling DH, the one head uses all 32Mb.

It might be Windows its fault then

Finally, someone noticed

I can understand the technical reasons for having to disable the dualhead support for certain applications. It still doesn't make it any less annoying, though .

I just wish Matrox would go to the trouble of including a page in the manual, or even info on their less-than-helpful online FAQ, mentioning the possible need.

With the i740's, I was fairly use to disabling the second monitor for gaming, but that was a simple matter of clicking off the option. I spend over an hour trying to get Expendable to run before I came up the solution of actually disabling the feature. I'm sure there are quite a few individuals out there who still have no idea why the bundled games aren't running...

I use DualHead all the time

- I NEVER have to disable DualHead for a D3D game.

- I NEVER have to disable DualHead for a TurboGL game.

- I ONLY have to disable DualHead to use the true OpenGL ICD (as per Winblows restrictions).

I don't know what problems you're all talking about, but it seems that your machine's drivers aren't installed properly. I normally run both monitors at 1280x1024x32bit. I drop to 1024x768 for Half-Life in a window, and amazing enough, it plays the same speed in a 1024x768 window as it does in a 1024x768 fullscreen (although it looks fullscreen, so I don't know what the TurboGL is doing...)

Anywho, just my $0.02

P.S. Jorden, that explains why games complain when I try anything over 1152x864 at 32bit color.

Actually, to date the only game I've had to do that (i.e. disable Dualhead and reboot) has been Expendable. I'm just annoyed at the amount of trouble I have to go through to utilize a game that really makes use of my G400. To be perfectly honest, I had played the Expendable demo a while back, and was not all that happy with the gameplay. I just wanted to see some nice bump mapping. I'm glad Matrox didn't design my MX300, or else I'ld have to reboot *twice* before playing Expendable.

And alas, my primary machine, which houses my G400, is powered by a pair of 567 mhz celery sticks, so the glory of TurboGL is *just* out of my reach. Sniff.. sniff...

I had purchased the G400 in hopes of getting a decent dual monitor implementation for learning OpenGL/Direct3D under Windows 2000. I guess I didn't choose all that well...

p.s. As I've already stirred up some emotions in a couple of my postings, I just want to state that I'm not trying to troll, upset folks, or pick on Matrox, and I hope no one takes my comments too personally...

C=64, we still craze for those days when PnP meant something, right? Plug in your Action Replay MkIV and flip that switch, then presto, it works

Primary system is my P3-450 with my G400 without problems.
Secondary system is my C=64 Still in use.

I miss the days when a ~1mhz machine with 64K of ram and 16 colors WAS state of the art...
