MiniDP
Look closely at the back panel, there’s usually a cryptic annotation about this.
Since you only have 2 MiniDP’s there, it’s likely that you can use all options:
VGA active
DVI single link active
DVI dual link active
Note that you don’t need to plug any devices into the TH2G for your computer to detect it as a monitor, so no need to plug anything into it if debugging catalyst’s recognition of the devices.
Since you are using VGA monitors, you should connect your 2xTH2G-D via VGA to the PC. I’d suggest trying this on the 2xMiniDP with 2xMiniDP-VGA adapters.
Your VGA<>DVI adapters are useful for 2 things only in your case:
Connect VGA monitor to your DVI-I output
Connect VGA monitors to your TH2G-D’s outputs if you feed TH2G-D with vga inputs.
They cannot be used anywhere else (e.g. on your DVI-D, or on MiniDP->DVI adapters)
you may be confusing that you can only have a limited number of passive adapters
VGA adapters should all be active (read: are always active)
some (most) single link DVI adapters are passive
so depending on your card, you can only have a limited number of these attached and working
generally this is 2, but I wouldn’t count on it always
@soguko: regarding triplehead, i have used my digital edition with digial input and analogue output and the other way round several times without problems. Not sure if you meant that rhis is not possible.

@sogoku have you tried updating the firmware, matrox have updated the firmware several times over the past years and they behave a lot better now.
I almost always carry one to use as a converter if I end up needing it and because when having the matrox software installed, whatever connected to the GPU can only be set to ridiculous resolutions if no edid is present.
@sunep - aren’t the modes stored in non-volatile memory on the device?
If you set the modes through software then plugin elsewhere you get the same modes listed
noted on the firmware updates. they’ve been giving me confidence :)
One note (such a useless place to put it): I can send DVI signal longer distances from the StarTech active DVI adapters than out of Matrox TH2G
I tried both active DVI adater and in built DVI and couldn t get the 10 meters DVI cable to work properly, it does work if you do some weird trickery, so that the GFX remembers the resolution.
