Probably I will change my GPU to be on the "right side" of the sync issue. ATIs 5450 seem to be a good choice.
There is something very interesting with NVIDIA cards: The capability to tweak every sync parameter (Advanced sync in control panel - Warning!). I remember having tweaked 60Hz down to 50Hz for some resolution that was capable of 60Hz only. In fact you can set any refresh rate you want.... I have never found such a feature with ATI drivers. Any comment anybody?

I have the 1090T 6-core Phenom overclocked to 3.7GHz. So far, it is the most powerfull CPU from AMD.
Because of flexibility (ffdshow, AVIsynth...), I only use software decoding (coreAVC 2.0).
What I can do with it:
- Play 1080p movies (overlay, reclock).
- Play 720p movies @double the frame rate (48fps, screen @50Hz, overlay, reclock):

- Play stereo side-by-side 2x720p movies with color correction (AVIsynth LUTs, VMR9)
- Play stereo half-side-by-side 1x1080p movies with color correction (AVIsynth LUTs, VMR9)
I didn't push my CPU farther (yet to be done), but I guess thats the best I can do with this hardware.
Trick: Although ffdshow/AVIsynth are supposed to run multithreaded, core#6 is often more loaded than the other 5.
So I always run Zoom Player with affinity to the first 5 cores (imagecfg.exe).That leaves more ressources on core #6 for ffdshow/AVIsynth.
I dont know if this is usefull with Intel processors, but with AMD its a big difference in stability!

About screen brigthness: Thats the point I am upset in my setup. I still dont understand why the infitec (Dolby-3D) technology is known as killing the brightness. See for example http://www.barco.asia/projection_system ... erview.pdf" onclick="window.open(this.href);return false;
Barco announces a ridiculous 7% transmission when using Infitec, as opposed to 38% when using polarizers (dual setups).
38-40% are the numbers we are accustomed to when using polarizers. I have tried both the polarizing way and the Infitec way. I must say that the brightness is exactly the same in both cases (color correction included).
What may benefit to the polarizing approach is the silverscreen gain that you have not when using Infitec. But I happened to see that this advantage is only if you are seated right in front of the screen (2.4 gain - 240% of the light). Even in that case, the screen sides may reflect less than 100% of the light (unless you use a curved screen - that I tried too).
Even if you use a narrow angle of placement for the audience, the side seats may perceive less than a 1.0 gain! You do not have this problem with Infitec. Everybody gets the same brightness, all accross the screen width, wide angle of seat placement.
Pictures are better than speaking... When I took a photo of my screen hotspot, he only words that came to my mind were: "Oh, my God.... I wasn't aware of that disaster..." (*):

"right side view" is for a seat exactly in front of the screen's right edge, which is a reasonable angle of viewing for the audience.
Dont pay attention to the wrinkle, they have been removed:

@blackshark
Have you tested the overlay on both screens? If it works (unlikely), that would be the perfect solution to my last issue...
(*) EDIT: Numbers are reported from photoshop assuming a 2.4 gain in the hotspot.
