FiosTV + LCD Monitor = Snow, HELP

[evilmonkey]

Just got Verizon FIOS TV installed and I am using an LCD as my tv. The Fios box has hdmi on it so the installer gave me an HDMI to DVI adapter. My problem is the picture comes through for a second maybe and then all I see is snow. This keeps repeating with no end in sight. Any ideas how to make this work? I'm using a 22" acer LCD. Currently the Fios box is set to 720p so there should be no issue, even tried 1080i but that was out of range it seemed. Any help is appreciated.

*edit*
The box is QIP-7100 P1 if that helps
