No display on projector or monitor
Might be being a bit thick but here goes:
In our drama theatre we have a computer connected to a simple video splitter which then goes to a monitor and an Epson projector.
All was perfectly fine with this until last week when, suddenly, there was no display on the monitor or the projector. I've replaced all cables. I've swapped the outputs to different ports. Nothing.
Both monitor and projector work fine when connected directly to the computer and other computers/laptops work fine through the splitter. Something tells me it's some setting on the computer that is stopping the display. I just don't know what it is!
UPDATE: No display on projector or monitor
Hoping for some help this time around. There have been a few developments.
We've tried three video splitters now and found the following:
- Attached the monitor to the computer - works
- Attached the projector to the computer - works
- Connected the VGA cable that usually goes from the computer to the splitter to the monitor cable - works
- Done the same to the projector cable - works.
When I put a video splitter into the equation, I either get a blank screen or a screen flickering wildly. That indicated refresh rate. Changing the refresh rate to all available options made no difference at all.
I'm at a complete loss now. Everything we've done points to the video splitter and yet we've swapped them for splitter we KNOW work.
