Default Re: Nvidia + Matrox TripleHead2Go with resolution 5040x1050!

I would expect that the LCDs are working fine when being directly connecting
to the video card :-)

Right, this is due to the bandwidth limitation of the DVI output.

BTW.: when i had the problem with my displays, i contacted Acer support.
The official statement from them was that "the native resolution of this Acer
display is 1680x1050 at 60Hz". One could imply that 57Hz are not supported.
however, EDID reports 56-76Hz, so it *should* work.

I'm just not sure exactly what to use for settings.
This is what i did on Windows to get the initial setup - maybe that helps:

1.) Installed WindowsXP (a version including SP2)
2). Installed the Nvidia driver (181.20_geforce_winxp_32bit_international_whql.exe )
3.) Installed the latest Matrox GXM tools (vxp2k_gxm_2_04_00_011_whql.exe)
4.) Executed the GXM Wizard and selected the 5040x1050 mode.

This brought me to the 5040x1050 setup where the 26 lines where missing.

Can you please re-installing the driver and the matrox tool to reproduce this
result? From there, it should be possible to adjust the vertical timing setting.

As mentioned, my hard driver with windows on it is currently not operational.
Please let me know if you strictly can't get it working, then i will look into it.
