Your comprehensive post has certainly helped me. Thanks.
I switch to single screen 4320x900 or 5040x1050 for gaming only. the rest of the time I switch to triple display mode 1920x1200 via dual videocard and use Ultra Mon to manage my multi monitor.
I presume this "switching" is a simple affair. That is, via a hot key or something.
If so, I imagine your set up is as follows.
1. Primary Card Head 1 -> TripleHeadToGo -> 3 monitors
2. Primary Card Head 2 -> spare port on monitor 1
3. Secondary Card Head 1 -> spare port on monitor 2
4. Secondary Card Head 2 - > spare port on monitor 3.
Is that right? Do monitors generally come with the 2 inputs needed for this?
If so could we also throw crossfire or SLI into the mix. Eg Use the two cards in SLI when using Th2Go, switch, turning SLI off in the process, to use the two cards independently. Is that kind of solution possible, usual, or desirable?
glad I can help, here's how my monitors are hooked up:
1st video card 9800GX2 nvidia (dual display)
2nd video card ATI FireMV 2400 (quad display)
Th2g is connect to DVI1 on my 9800gx2
-=-= MONITOR CONNECTIONS =-=-
Left monitor - DVI to port in FireMV
- Analog to Left output on TH2G
Center Monitor - DVI to center output on Th2g
- anaglog to 2nd output on 9800gx2
Right Monitor - DVI to port in FireMV
- Analog to Right output on Th2g
-=-=-= DISPLAY MODES/SETTINGS =--=-=-
I use UltraMon and have hotkey or 2 clicks to switching between screen setting. I mainly use two modes. this is in windows
1) Triple display: 3x 1920x1200 (for regular work)
- L and R monitors are run from the DVI port on the FireMV
- center is run form Th2g via DVI in 1920x1200 res.
2) Matrox Th2g: 3x 1440x900 (for gaming)
- disable DVI output from FireMV to L and R monitor
- th2g runs at 4320x900. Center monitor run by DVI. L & R run by
th2g but in analog mode and the monitor automatically switch to analog input since it autodetects and the DVI feed is stopped.
3) Analog gaming: Single 1920x1200 VGA Direct connection to center monitor
- I have to set SLI output from matrox dvi port to the other port on my 9800gx2 via Nvdia control panel
- I only use this when I need to play games that have to use pesky resolutions or when the game gets " blank screen but runs" because this direct connection to the monitor gives more usable resolution without bugs than say the th2go that only have a limited mode.
I'm surprised it worked out so well with no major bugs other than my Th2g not being able to use single 1920x1200 in games.
Th2g is only used when I game the rest of the time it's useless and my 2nd videocard + ultramon does a better job. and can use my monitor's full resolution.
