We are using a Dell XPS 8700 Desktop Computer running on Windows 10 Pro. It has 24 GB Ram, Intel Core i7-4790 Processor CPU @ 3.60Hz, 64 Bit OS. Video Card is a GeFOrce GTX 750. We use this computer in a church with Easy Worship Presentation Software and are running 2 In Focus 124 A Projectors with VGA Hook-up through an Altinex DA1907LX Booster/Splitter. After startup and opening Easy Worship 20 to 30 Minutes everything freezes up. We have to manually shut off and re-boot. I know the VGA cables are 100 foot cables. What might be the problem and solution to our problem? I have checked with In-Focus, Easy Worship, and Dell and they have all given me the run around i.e., check with Dell, or check with In Focus. You get the picture. Please help!!
