DualHead Win2000

[MartinS]

A colleague at work has just bought an OEM G400DH and was running 2 monitors at different resolutions in Win98 - lovely. After migrating to Win2000 he found that the DH just treated it like a virtual desktop stretching the display accross the two monitors.
I've searched through the Forums and there seems to be some debate about whether this is a Win2000 or a Matrox driver problem. Which is it and is there a likely to be a fix scheduled by Matrox or is it simply a matter of waiting for Win2000 SP1 ?

Thanks.

It is a 'limitation' of Win2k. It works just like Win98 if you have two seperate graphics cards, but sees the G400DH as just one. Microsoft *may* 'fix' this with Service Pack 1.

What's the difference between "streching" and "real support"? I don't have DH so I'm just curious..
But I doubt that Microsoft will release any fixes for this as I recall that Win NT didn't have such support either.

Personally, I'm quite upset at this issue. I purchased my G400 Max under the assumption that Matrox was able to sustain its claim for "Full DualHead Support" under Win2k upon it's release, as oppose to their "Limited DualHead Support" under Windows NT
(see http://www.matrox.com/mga/press_room...0_brochure.pdf page 4)

Before this, I had two seperate video cards for DualHead. They were begining to show their age, so I thought I'ld go ahead and get a good performing, integrated solution. I can honestly say that I would NOT have purchased this card if I had known of the possibility of this issue, and its irresponsibly for Matrox to make such blatantly false claims.

How dare you ever say matrox makes blatantly false claims! hmm, where are those opengl drivers for my g200.

Buuri,

the difference between stretching and "real support" is that with the latter each monitor has its own properties and can be set to different resoloutions etc. in win2k it is just one big monitor...for example, i have a 21" on the primary @1280 x 1024 16 bit and a 17" flat panel display on the secondary @1280 x 1024 16 bit...what i get is a desktop that's 2560 x 1024 16 bit.

i've removed win98 and am totally using win2k now for 3 weeks and have really gotten used to the win2k scheme, and it isn't that bad. in win98 i couldn't get streaming media to work on the "second" monitor. i could drop a real player video clip on the second monitor and the video would stop but the sound would continue. in win2k it is just another "area" of the monitor, same goes for powerDVD.

i like it so much that i hope matrox makes it a user option to choose which scheme to use.

One of my customers has a 21" tube and a 15" flat panel thing. Now neither NT nor W2K can handle different resolutions on these monitors. There should be a better solution for CAD users these days than going back to 98. This is driving me nuts already.
