Using a Flat Screen HD monitor with Power Mac 9600. Monitor says no signal. I used a DB15 to VGA adaptor cable for years with CRT monitors but when my last monitor died I had to try to move to new LCD monitor. Have changed the adaptor to new one thinking that was the issue. I set the switches according to the accompanying product guide but still says no signal. Anyone have any ideas if direction I might go to solve this.
My Mac is a Power Mac 9600 with 233 MHZ.

Does your HD monitor support the resolution your Mac is using?

What OS? What monitor? What adapter? What GPU?
Set the adapter to separate horizontal and vertical sync?

You can get GPUs with DVI ports which are compatible with HDMI displays.
