Custom Resolutions with W2K + 5.10beta?

[Minstrel]

Since the new 5.10 beta drivers have monitor customization I thought it might be possible to add custom resolutions to the drivers, similar to the win9x drivers (1280x960 for instance).

Does anybody know if this is possible with this new release, and if so, how to do it?

Thanks.

A new Resolution Manager is on the way.

If you want to hack the registry directly, go to HKEY_LOCAL_MACHINE\SYSTEM\Current_Control_Set\Serv ices\G400\Device0. Edit the value Mga.SingleResolutions and add the resolution you want to the end of the list of bytes. The format is WW XX YY ZZ where XXWW=the 4-digit horizontal resolution in hex and ZZYY=the 4-digit vertical resolution.

Then create a new binary value called Default.Graphic.hres.vres for your resolution. Copy the bytes from a nearby resolution into the value of the new resolution. For example, to create 1280x960, create a binary value called Default.Graphic.1280.960 and copy the hex values from Default.Graphic.1280.1024 into the 1280x960.

Once you are done, reboot, and then go to the monitor customization tab in Display Properties to enable and tweak the new resolution.

The new Resolution Manager will be just like the one for Windows 9x, except that it will have a lot fewer registry tweaks (since very few are known), and also it seems a reboot is required for any new resolutions to become available.

Keep up the good work Mark!
Have you managed a way to disable Vsynch in win2k drivers?

Hi Nuno,

I'm not much of a gamer so to be honest I haven't really tried to find a VSync setting or any other 3D-related settings. I did a quick search of the forums and a few posts suggested setting User.FlipOnVBlank = 00 00 00 00 (Type Binary). However, I also saw a few posts, including yours, that said this stopped working after a certain Powerdesk version.

Have you tried the same setting only with User3d before the dot instead of User? I only suggest this because there is a setting called User3d.UseZ32 for the 32-bit Z-buffer option, and perhaps the other 3D-type settings are now all lumped under User3d.

Just a guess!

Ok, I'm looking at the ICD file (g400icd.dll) in a hex editor and some ASCII text is visible:

User3D.SIMD
User3D.TexUpdateAreaSize
User3D.Boxes
User3D.PuntAll
User3D.NoFill
User3D.NoSwap
User3D.NoPost
User3D.UsingBufferRegionExt
User3D.BufferRegionExtEnable
User3D.SwapIntervalExtEnable
User3D.SwapIntervalExtFlags
User3D.PageflipEnable
User3D.NumBuffers
User3D.BufferSize
User3D.16BitTextures

Now here is some stuff from g400m.sys:

User3d.ZBuffer

So much for not having that many registry hacks for Win2k! I would guess that one of the following should take care of the Vsync problem:
User3D.PageflipEnable (OGL)
User3d.SwapVsyncEnable (D3D)
User.FlipOnVBlank (2D?)
User.FlipWaitVBlank (2D?)

Have fun!

Wow, you can sure find out a lot of cool stuff with a trusty hex editor...

At offset 01A430 in PDTools.dll:
Matrox G800 AGP
Matrox Fusion G450 AGP
Matrox Fusion Plus G800 AGP

In fact, every Matrox card name since the original Millennium appears between 01A2CC and 01A61F in this file! Perhaps there is a unified Win2k driver in the future for the Mil 1 through the G800!

Just some more info on custom resolutions...

The Horizontal Resolution must be divisible by 8 and the Vertical Resolution must be divisible by 2 for the resolution to be valid. I noticed this in the first Win2k Resolution Manager, but I thought it was because I was hacking the driver instead of using registry settings built into Powerdesk. Now it seems that it's a fact of life in Win2k (unlike Win9x which allows any values for the resolution).

Matrox Fusion Plus G800? Ouch! Sounds like you need multiple credit cards in SLI mode to order one.

[dZeus]

the fusion stuff:
I suppose that is a dual-chip config?

since there also is a G450 fusion, it means there will be a dual-450 board? Seems very well possible to me. Since they use DDR-SDRAM and half the bandwidth, the traces also are cut in half. That causes much less problems for designing a dual-chip config. Even better: maybe Matrox has figured out a way to make a dual-chip config with no hardware requirements. But this seems unlikely, so I guess they incorporated multi-chip config in the G450 chip.

[Minstrel]

Hey, thanks for all that great info!

[Nuno]

Mark, you´re the best!
Going to try it rigth away.

[MarkV]

Ok, let me know if you have any success!

[MarkV]

A quick correction on my previous statement on custom horizontal and vertical resolutions with the Win2k 5.10 beta...

The horizontal resolution does need to be divisible by 8 but the vertical resolution can be any number.

I haven't had time to work on the new Resolution Manager yet. Hopefully soon...right now it's too nice out to be stuck inside programming!

I still couldn´t disable v-synch
Mark, could you precise where in the registry these entries should be?
