Ok..I removed all the 4 HDMI cables which are a mix of 1.3 and 1.4 and plugged each one directly from laptop to projector and all worked..hence nothing wrong with cables.
Anyways..I just plugged all of them again and for some weird reason now it works
Also opened my 3D DLP glasses and my 3d works well. Again first impressions were that 3d on my plasma was better. I had spent many days downloading a 15gb rip of avengers 3d and frankly it seemed to suck.
after trying few more rips..finally i settled on my LG demo video and this one really shone on my 3d - I got two versions...one SD version and one long HD version...the longer one that starts with a guy playing tennis....was really good.
now I got some questions:
Clearly when I compare the same movie between my plasma and projector..plasma seems to be better.
since I always have XBMC issues, I usually use GOM player since it seems to play everything flawlessly.
My monoprice too has a 3d effects increase and decrease button..but not sure if it works on native 3d....or just 2d to 3d conversion.
so net net...am happy with 3d but yet to get that full pop up effects. Problem may not be entirely with the projector or the monoprice.
does the application with which I play 3d also make a difference?
what other things do I need to keep in mind to enhance the 3d experience?
Also one other thing I noticed..these 3dLP glasses..though heaver than my cheapo samsung for plasma tv - are very comfortable and 3D is much better - not interms of popups but the picture is very clear. When I watch 3d using my cheap samsung glasses on my panny plasma..I clearly see that thing - distortion or ghosting or whatever its called wherein you see shadows everywhere.
will watch more movies and update my experience.
