I would guess it could be a cable or source issue. Is it a blu-ray player, satellite box, PC etc.....are there output settings on the source that you can change? Eg, sky tv, set it to output 720p or 1080i. Is there an amp in between source and projector.
If you post a more detailed explanation of your complete set up, start to finish it will be easier for someone to spot the issue.
If I went on to a car forum and said "my engine is making a funny noise, can you help?" Thats not really enough detail to go on. I'm not having a dig, just struggling to know what the route of the problem might be.
Ok I'm using a xtreamer media steamer. I have a amp which projector connects to also my streamer is also connected to the amp not directly to streamer. I used to have emitter in past and no trouble but this time there is
When you go into the info part of the menu on projector, what does it say, eg, 1080p 24fp and does this match what the output of your source is. Check if your amp is on hdmi pass through or is it scaling?
I don't think it's the emitter as it still flickers when the emitter isn't connected. All the emitter does is tell the glasses which lens to open and close and at what time - if the picture flickers without any glasses on then it's something else - not sure though.
Have you tried running the hdmi lead from media player direct to the projector?
