Ryan,


Sounds like a nice setup you have going there, but the TV is going to be fussy about resolution. You need to plug in a regular monitor to adjust the resolution to something higher than 800x600, preferably 1280x720, make sure the screen comes back up on the monitor, then reboot the computer with your tv plugged in.

Please let me know if you have any more questions.


Thanks.

Matrox G450 and DX9 support.


The Matrox Millenium G450 is a DirectX 6 video card, so it doesn't support the features of DirectX 9, hence, there is no way to make it work. You will need to get a newer video card.
