Projection Screen

[MartinK]

Hi Benno,

TV's is a difficult one. First of all, there is the refresh frequency usually somewhere around 60Hz. The TH2GO unit is pretty sensitive to this.

Secondly, what mode is the TV in pixel wise? Does it support e.g. 1024 x 768?
Remember, there is only a few pixel modes the TH2GO will support (see their website for an overview). If the device connected is out that support range or fails to adopt to the supplied signal then you get what you are experiencing: No Picture!

I am assuming the TV's you are using do have a VGA or HDMI interface.
So, what is the brand and model TV you are trying to connect? And what interface are you using with what mode?

Also, if you bring up the GXM user interface what does it say in terms of devices it thinks is connected to? I bet it recognizes your monitors but if you connect the TV's it does not.

A lot of questions but actually meaning areas to look at and possibly correct.
From my experience I would start with pixel size and if that is correct then the next thing to look at is refresh rate.

The projectors I am using have auto sensing so they will adopt (within limits of course) to the supplied signal. But, I had a situation initially where the supplied signal was out of bound so I had to make changes before they would project a proper picture. Sorry to say, but your setup requires a lot of trial and error and thus a lot of patience.

Just let me know how you are progessing and don't hesitate to contact me.

Cheers,

Martin

Hi Martin,

The TV's are Samsungs, Full HD, 37" LCD
They also have autosensing, given the fact that when I connect them directly to the graphics card in the PC, an excellent image turns up!

Somehow I also think it's the resolution or the refresh rate of the Matrox that is causing the problems.

I cannot connect the TV's and then start configuring, since there is no picture...
So I have to try doing this with a normal monitor connected to the firt DVI port and the TH2GO to the second.

Any tips?

Rgds,
Benno
