Sounds like the the monitor detect line is causing your issue. The
Hitachi CP-X250 has VGA in & out. Hook the Dell to the VGA out port of the projector.
Most likely you have a defective lamp or it is near the end of its life. It's also possible that the high voltage power supply is going out. You might check the lamp hours - you can find this in the advanced menu. Also check the air filter, if you haven't cleaned it, the airflow might be restricted, shutting down the projector.
A usb cable will not work that way--on your projector, it's used for data...you need to obtain a monitor cable which will plug into the vga connector on the laptop and into the connector on the projector (rgb in 1) or (rgb in 2) If you use the #2 rgb input, make sure the button IS NOT pushed in! If it is, the projector will be switched to OUTPUT mode on the #2 connector. Also, on the laptop, normal operation is "laptop only"...when you push the <alt F4> buttons, it should then switch to "laptop + external display(projector)", another <alt F4> push will give "external display only" mode. Then, another push will return you back to "laptop only". NOTE: Sometimes, you have to turn on the projector first, then immediately turn on the laptop--not to get technical but different equipment can get finicky about syncing up...just something to be aware of...
I am not a 100% sure, but that would be my first thought on what the problem is. I would call Hitachi support and go through troubleshooting with them to find out the cost of the repair.
