TripleHead2Go digital not working

blackrat · Post by **blackrat** » 30 Jul 2007, 14:06

The problem I have, its usually not detected, the 3 screens keep black.

Changing the connections on the monitor and the USB cable sometimes works, so I could play sourround gaming, on seldom occasions.

When plugging in USB no hardware recognition is running, so I assume it's only used as power supply (or should be hardware recongntion?).

The PowerDesk application usually is not running, even if I start it manually. (Despite it worked some times, so I could set correct res: 3840x1024 32 bit). Does anyone know if this is a driver and needs running or only configures the box with the 4 resolutions?

Maybe some people are already using the digital edition and can help me aout a bit.

USB is for power only, no detection of hardware AFAIK.

Check that you have plugged it into a powered USB port, if so, then you will get a power light on the TH2G itself.

Do you have a light for power at this time?

Mine acted weird like that until I moved it from a powered USB hub to a port on the back of my computer.

Here we go ...

So no defined statement other than it has to be a powered USB Port, all my hub's ports are powered, so I wouldnt expect this top be a problem if and when I try one ...

But it is a concern ...

Jkeefe, did you have the power light on the unit when it was on your hub ?

The light was doing weird things - red, green, off, red again, green, back to red. I would get a 3840x1024 desktop and then all three screens would go black. Don't know if moving the plug to the motherboard port helped, or I juest rebooted enough that my computer unconfused itself. Either way, I haven't had any problems since.

There may have been a conflict with residuals from the analogue triplehead2Go, as well.

Interesting, just trying to acertain whether or not it has to be in a MB port, I would believe going by Matrox that it just needs to be a powered one, and I know my hub meets that spec, as I have other devices that only have a need for USB power that are in it.

I didn't get to try mine, as I sent it back RMA, awaiting the supposed corrections mentioned in another thread.

I have the same problem for my TH2Go.
I found a solution :

Before starting ur Computer, just unplug the power adaptator of your Hardware and plug it again.
The TH2Go should be recognized.

Sorry for my english, french inside ^^

SGs solution is what I do as sometimes I woould boot and the monitors would not power on and the TH2G would stay red

I actually have 2 th2g and they both behave the same

Solution is too remove PC power before I turn on pc

it worked for me but i've returned the TH2Go because red dots were appearing on middle display.
After some days the Middle display is not recognized anymore.

To return the TH2Go is at your charge...
And they send you back a new one, wich i hope will work.

Guys,

I have been talking to Matrox Support in the back end and was just sent the following: We are working together still as an FYI

------------------------
The USB cable that is used with our GXM products is used to communicate/detect and power the unit. We have noticed that some laptops and motherboards seem to have some power budgeting issues on the USB ports.

What you have described below sounds like a power budgeting issue.

If applicable, you can always try using the USB ports that are sometimes located on the monitors/panels themselves. This is sure way of sourcing power from a dedicated source.

I don't believe thats the case, braddo:

E.g. when I go start button, restart, the screens will be black after restarting.

If I shut down PC normally, put off monitor (with USB hub where I have connected TH2G), put on a few seconds later, start PC everything's normal.
Off course, I tried different USB ports before with no difference, it's only esier to put power off in this way.
