Yousefjuma Posted February 13, 2016 Report Share Posted February 13, 2016 Hello everyone, I hope you all are doing fine. We have faced a problem during a project previously that we couldn't figure out the solution for, and that's what are seeking now. We had a simple setup of 2 stacked projectors connected to display PC that is controlled by production PC. The connection between the projectors and display PC is fiber optic, subsequently, we were using DVI-Fiber optic converters at the projector and production PC ends. The projectors should be receiving signal of 1400x1050 60Hz. But for some reason, Windows is just offering the option of 1400x1050 24Hz only when we are connecting both projectors simultaneously. Which, of course, isn't supported by the projectors. However, when there is ONLY ONE of those projectors connected at a time to the same display PC with no changes in connections or whatsoever, Windows gives options of 1400x1050 60/75Hz. P.S. We had imported EDID info from projectors to the DVI-Fiber Optic transmitter/sender. Systems specifications: -Projectors: Christie Roadster S+ 20K -Graphics card of Display PC: we tried on two different Display PCs one with ATI FirePro V8800 and the other with Nvidia GeForce GTX 780 -DVI-Fiber Optic converter: Gafen DVI FM 500 We would really appreciate your suggestions on how to solve the issue. Thanks in advance. Quote Link to comment Share on other sites More sharing options...
