I shall try and take some pics soon.
In the meantime I have some more observations. Previously I was projecting onto a newly plastered wall, so the swirl marks were hiding some detail - I've quickly rolled on a coat of white emulsion so I can see the image better.
Now I can see the blend zone, which I think is still mainly due to colour balance, BUT there seems to be a darker strip just on the right hand side of the blend, which is a bit strange.
I tried each PJ individually so I could see the fade out, and found that the left image fades to black on the RH side, but the right image fades a bit then seems to stop before it reaches black - so the overlap doesn't seem to be symmetrical for some reason. I think this is the reason for the dark strip I can see.
I seem to have to slightly adjust the image position of one PJ to get the alignment of the blend perfect when changing between different aspect ratio material. This possibly is becuase I don't have both PJs yet projecting at EXACTLY the same size, or some other mismatch like that, so I'm not too worried about this at the moment.
On panning scenes, or rolling credits, I can see that both images are not perfectly synchronised, i.e. there is a very slight lag on the second PJ. This could be down to the speed of my PC (I think its a 2.4GHz P4) or possibly the graphics card? The computer is not fast enough to play back HD material properly anyway and this lag is very apparant when trying! (Although VLC makes a better job of playing back WMVHD than WMP).
I discovered lots of controls to adjust the aspect ratio detection in the advanced settings of panoramix. So I'm able to tweak this now to avoid the 'flashing window' syndrome without having to set a fixed aspect ratio.
For some reason my graphics card (a Radeon something or other) doesn't want to display 1280x720 even using powerstrip, so at the moment I'm using 1280x768@72Hz. I'm not sure that the 801s can really resolve 1080p even using the full phosphor height, but 720p (actually 768) is very clear. Having said that, I havn't really put much effort into trying 1080p, I still have a little bit of phosphor height left to play with so it MAY be possible.
Thats enough playing for one day,
