I'm sorry about the issue. What's the model of your projector?
If you test connecting the projector straight to the laptop (without using the splitter), does it work?
Have you tried with another cable for connecting from projector to laptop?
Please let me know. Thank you.
Sorry, I missed the part where the projector is working without the splitter.
Do you have windows xp, vista, or 7 or 8 or 10?
If you set the display option to show only on the external display (i.e., not duplicate, not showing anything the laptop's screen), does it work on the projector?
If you connect the splitter to the laptop, then connect only the projector to the splitter (don't connect the TV), does the projector work?
Please let me know. Thank you.
1. Do you mean previously, all the 3 screens showed up at the same time, i.e., the display showed up on laptop's screen, TV's screen, and projector's screen at the same time right?
2. And now, you can make the display to shows up on both TV and projector at the same time when making it not showing up on the laptop's screen right?
3. If you connect the splitter to the laptop, then connect only the projector to the splitter (don't connect the TV), then the display works both on laptop's screen and projector's screen right? Then don't disconnect anything, but connect the TV (connect the TV last) to the splitter, then what happens? Does the TV not show anything? Or does the display switch automatically from projector's screen to TV's screen?
I'm sorry. If you connect a TV and a monitor (instead of the projector), do they work fine?
You've tried with another laptop and another cable, so I think there is something wrong with the projector, even though it works standalone. I don't have any suggestion, so let me open the issue to other experts. Thank you for your patience.
Hello, and i think i know what the problem is......the SPLITTER went BAD.
They are cheap, and the components that actually do the splitting are VERY VERY cheap.
DO NOT USE A SPLITTER...use a SIGNAL REGENRATOR. instead of SPLITTING the signal, a regenrator accpets the signal, THEN MAKES A COPY OR TWO OR THREE, and then sends it on. There is NO dB loss this way, and its more reliable.
Hello Alain, I noticed that your issue is still outstanding and wanted to offer any additional assistance. Quiksilver may be correct about the splitter. It isn't the optimal way of setting it up but you said that it has worked before. Have you gone into Windows and ensured the signal was being sent to the projector?
You can hold the Windows flag key and press "P" to bring up the menu. Select duplicate or extend, whichever you need, and see if it'll show. You can also choose just the projector or the TV and see if you can switch back and forth. This would be helpful to know for testing purposes.
It's possible that it could work but my thinking is if you had it working before then it should still be able to work now.
And just to clarify, did you test the signal to each device while they were both connected to the splitter?
I found this signal amplifier/splitter from Monoprice, and should do the trick.
