Re: video spliter question?
It seems like the resolutions you are wanting to run at, and are running on the native screen are not compatable with the monitors/projectors you want to run them off.
Remember, some older TV's won't display properly a HD resolution, and some projectors maybe the same, OR you have the Hertz rating set to high, and your projector/TV's can't run higher than 50/60hz and your video card is outputting at 75-80hz, as an example.
The reason why it would go off after Windows starts is because the bootup runs at 640x480 at 60hz, whatever you have the Windows resolutions/hertz settings set to.
Then when Windows is starting, it could be switching to a higher hertz that the original display allows, but the other displays can't accept it and so move to standby.
So check the source resolution, and the source hertz ratings, and change them to suit the displays you are using.
Only problem with the splitter method, is after you do this, every display will have to have the same resolution, whatever size the output is, which may look terrible on a larger monitor, but great on a smaller monitor.
