Ok, I have a question. I know enough about A/V to be dangerous and am pretty well versed in Computers so I think I may have a solution to the problem but I want the experts advice.

Here is my setup first off: (1) Windows 7 with (2) Nvidia Gt520's, (2) Optima Eh1020 1080p DLP Projector With Hdmi, (2) sets of HDMI extenders over Cat5, (1) 1x2 HDMI splitter.

Ok, long story incredibly short. The church I work at hired a company to install a two projector setup over HDMI. The company was responsible for everything but the computer which I built. Due to multiple issues I let go of the company this week and began to get the system up an going correctly. In the 3 weeks since the installation has finished which took over a month (should have been first hint) we have replaced all the Cat5 lines as there were multiple places that had been cut due to it being forcibly pulled through the conduit, replaced a projector and replaced multiple splitters due to them not working.

The biggest problem is the splitter now. This signal consistently kicks in and out, or just doesn't work at all. After looking at the entire setup, Im pretty sure, in fact positive from even the little knowledge of A/V that a simple HDMI splitter will not work on a computer due to the lack of an EDID. Plus since the setup already features a HDMI over Cat5 setup the use of an independent splitter seems dumb so this brings me to the actual question.

In my searches online for a slitter with an EDID I came across an HDMI over Cat5 splitter that is HDCP capable and an EDID. So would this be a correct solution to my problem? HDMI 2 Way Splitter Extender over CAT5e Extends HDMI 150 Feet over CAT5e

Thanks ahead of time!

Could you go into a bit more detail about the setup? I can't see where the splitter fits in. You've got four outputs, two cables and two projectors and no apparent reason to duplicate a signal in hardware.

Computers will happily ignore EDID and send out whatever resolution you want, Microsoft even has an article on one way to do it in their own website. I don't have any experience of what happens when windows can't find an EDID but I'd imagine the result will just be that it gives a list of default resolutions, I can't see how it would cause the sort of intermittant problem you're describing.

ya def. We are needing to put the identical image on both screens and the presentation software we are using, ProPresenter, only has 1 display for primary display, 1 display for stage display and 1 display for a monitor. Hence he need for the duplicate signals.

Thanks for the EDID link, I'll give that a try.

If you have another suggestion for set-up that would be much appreciated!

I'd be inclined to duplicate the screens on the PC if possible. I'm not familiar with the nVidia control panel but won't it let you set one card to mirror and one card to extend? Or for each individual monitors?

If not then you could try Ultramon, it'll let you mirror one screen on another but I'm not sure how smoothly it would handle high quality video.

From what I can tell it doesn't give me that option like I would have Catalyst Control. Unless there is someone who has found it in the Nvidia control panel.

Thanks, for the ultramon idea
