Setting up three displays with MATROX - HELP

[cwolf78]

ok, I am setting up three Samsung 22" syncmaster displays through my Matrox T2G-D3D-IF Triplehead2Go Dual-Link Digital Input device. My PC is running Vista x64 with a XFX 9800GTX card. I have installed the latest drivers from Nvidia (which seem to be more current than the ones from XFX) as well as all the latest drivers and software from Matrox.

Here are some of my issues. When I set the resolution to 3840 x 1024 I get the center monitor full and the two side monitors with a scaled 4:3 looking desktop. In 3840x768 everything is widescreen and the desktop is continous across all three monitors.

Next issue, I cannot access the higher resolutions that are available to my machine (according to the Matrox compatabilty software) namely the 3x1680x1050 (5040x1680)

Here are two issues I can think of that may be causing me some problems, but I have no real proof that it is either.

1) Right now I have a different Samsung monitor mixed in with two newer models. One is a 226BW and the other two are 2253BW... I have another 2253 on order.

2) I am using a 'heavy duty' DVI cable with the old monitor (226BW - which is the one that in the center from my description above) and the smaller 'stock' DVI cables that came with the two new 2253BW monitors (the ones on the sides from my description above)

If anyone has any experience with the Matrox series Triplehead2Go Digital I would be very appecaitive of their input. Thanks !

1- You need to update the firmware in order to use widescreen resolutions.

2- With this firmware update, you are limited to 1440x900 resolution per screen.

3- You should have done your homeworks before buying this stuff.

Did you read my original post ? I have installed all of the new firmware and drivers from Matrox.

2- With this firmware update, you are limited to 1440x900 resolution per screen.

According to the Matrox website and the compatibility software available from the Matrox website my machine is capable of 3x1680x1050.

Montreal, Canada, August 5, 2008/PRNewswire - Matrox Graphics announces new triple widescreen modes for the TripleHead2Go Digital Edition: 3x1680x1050 and 3x1440x900. The new modes allow gaming enthusiasts and professionals to benefit from the advantages of widescreen technology across an astonishing desktop set-up.

3- You should have done your homeworks before buying this stuff.

Is reading about the required capabilities/hardware from the manufacturer not considered doing my 'homeworks' ?

Also, the question of why I may be getting a 4:3 scaling issue on the two monitors on either side was not addressed by you inaccurate info about what my max resolution should be. I believe this is a simple setback, be it a driver I have overlooked or a cable that needs to be upgraded.

Did you remember to set the resolution you want to use in the PowerDesk software? Step 6 and on this page. If you did that and it's still not going you can try contacting Matrox's support they are usually pretty good at resolving issues like this.

The WSGF is also a really good community of TH2G users.

I did follows those steps... unfortunately the new resolutions are not available in the PowerDesk software.

I will check out the WSGF right now. I emailed customer support yesterday and I am waiting for a response... I might try calling later this afternoon. Thanks for the pointers !

I got it fixed. The tech support was very good... the tech I talked with established a remote connection and helped me narrow down the problem. I ended up having to roll back my video driver ...

5040x1050 is pretty cool
