Hi Everyone, I believe many people out there are very interested in playing games on Projector with 3D Glasses. I hv search for numerous website for projector that support more than 100Hz and SVGA. Looks like Acer have a model that support the above specs. The model is 7765PE. Anybody have try that out? Please give us posted for the result on any projector that work with 3D Glasses. | ||

Most likely these specs indicate which input frequencies the projector accepts on the analogue VGA-input. From there the VGA-signal goes into an analogue-digital-converter and gets - in all likeliyhood - a treatment which will destroy any shutterglasses-stereo-format. I doubt the actual DLP interface and chip goes much higher than 60 Hz refresh. I fear that in order to construct an above-60Hz-stereo-capable DLP the basic technology would have to be changed. This is a job for Texas Instruments, not for the projector-manufacturers. Anyway, everybody who gets his hands on any DLP - keep trying. Christoph | ||

I recently tried with the Davis DL X10 and DP X16. I was told that if you enable "video mode" in the projectors' setup menu, they would sync to the vga input and thus bypass their internal frame rate converter. As Christoph suggests, it worked with up to 60 Hz. All faster settings produced a garbled stereo image. Apart from the low refresh rate resulting in heavy flickering, the stereo image was excellent. No ghosting AT ALL. I was told by the Davis guy, that some (non-Davis... Davis is shutting down) projectors might work. It's due to the colour wheel: Davis' colour wheels have four fields: Red, Green, Blue and White. Other projectors, however, use a six field colour wheel with RGBRGB. Meaning that at the time the Davis' colour wheel cycle through RGB once, these other projectors do it twice. Assuming a fixed rotation of the colour wheel (I don't remember the figure... think it was a hundred and something revs per minute), these projectors would be able to achieve the double refresh rate - i.e. 120 Hz. Unfortunately, the projectors he mentioned were expensive - plus 10.000 € or US$. But there might be low-end projectors out there using this type of colour wheel. Unfortunately, I don't know how to find out which. Now I'm wondering, if one could double the flickering rate of the glasses while staying at 60 Hz field sequential image... Then each shutter panel would flicker twice per field, resulting in a darker image, but probably reducing visible flicker. Any opinions on this? Anyone care to draw a "shutter double circuit"?

NB! Moving part of thread I'll move the last suggestion to "General 3D Discussion" (hasn't got much to do with "News" or ACER projectors. Alex | ||

it's not only about flickering. at the times of the flicker the shown image has to be changed from the right image to the left image etc. if you stay at 60hz, and just double the flickering rate, you will just see the first copy of the image with your left eye, the second copy of the same image with your right eye, then the image will change, and you'll see the right image with your left eye, then the same copy with your right eye etc. no 3d is possible that way. |
