You should wait not because you are a European, 🙂 but because you are being premoderated for a while. After several posts (10? 20?) premoderaion will be disabled for you by board moderators, and your posts will appear immediately.
Yes but you must wait for the americans to reply your posts... Maybe you should sleep at days and write here all the nights.
Btw, I haven't ripped apart my Benq yet, but I think that the grounds of the controller board and power supply should be connected together (with the green wire propably), otherwise the thing doesn't work properly. It doesn't have to be connected to something with metal though, just interconnected. I think (was it from Kolima's experience) that with regular PC workstation (with grounded PSU) it worked without the ground wire but not with laptop. It's upto ground wiring in computer PSU's how it will work (don't panic, just think clear).

Yep. My most productive time is a late night, so I don't generally have any problems with time zones. 🙂
Another NON-fan of the 10-or-so moderated-post-thingy. I can understand 4 or 5... but 10-20 seems a little paranoid to me.
ouch Vm..the guy is gone and your STILL dissing him 
lol
any who i think ppl are being moderated to crack down on terrorism and so on.....well..its possible..🙄

Games, gaming, video and ghosting on the Benq
Hi guys
doing my research I was concerned re some of the comments earlier on regarding ghosting and dithering.
Here is a review on one of the top gaming sites for the FP767 16ms response time LCD.
http://www.avault.com/hardware/getreview.asp?review=benqfp767lcd
Happily they report very little ghosting in games and dvd/video playback. They did not notice any dithering artifacts or colour issues...
Very encourging as I want to set up a massive gaming screen.
Hope this helps 😎

Is it true that you cannot use this benq 557s or 567s unless you split the fresnels to get a decent image?
And what on earth would an lcd do that would only work when splitting fresnels and putting one in the image path?
LCD's use polarizers, which block light in certain directions. Sparing the physics behind it: fresnels make the light path more compatable (more light passes through) with the polarizers on certain LCDs.
Why splitting? Because for coll./cond. fresnel, the only place the light path is normal(perpendicular) to the surface of the fresnel is in between the two fresnels. If you split them and place the LCD in between the two halves the majority of light passes through the LCD with a normal(perpendicular) trajectory, causing an optimized amount of light to pass through the polarizers, and the LCD.
It's kinda like that...

In addition to splitting fresnels you also have to tilt the Benq 557s/567s LCD 20 degrees till 6 o'clock for the optimum contrast. That's the optimum viewing angle with that AUO panel. Wonder what is the optimum viewing angle with CMV1515, anybody used it as normal monitor?
Built my projector using 557s
It works fine.
Contrast superb
No Ghosting.
Massive improvement on DVD quality once upgraded to a ATI9800 Pro from a GF3.
I use an Ikea blind as a screen and an Elmo 4000w OHP.
Hotspot in the middle of screen. Eliminated by cleaning mirrors and lens. Caused by condensation on the OHP mirrors.
Next is to get 3d working with shutter glasses.
Will post results when I can.
Thanks for all your help guys.😀 😀 😀

Unclebob have you compared your 557s split fresnels with not split fresnels of some other 15 inch?
The 557s and 567s are available to me for $270 ship everything but I am now hesitant because I was planning on keeping the fresnels behind the lcd (OHP style) for a sharper image.
The other option is cmv1512 for $410 shipped. Should I just go this route since its 24 bit and slightly better contrast.

Hi Unclebob:
Try this Link for info to 3d. He is using A Benq 567 With 16 Ms Response time...

More work is Needed, but it's a Start...

Mov Lab - Thanks (same interests then) its me!
Nvidia helped but not enough. No one bothered to tell me what the numbers in the config file would do. 🙁
So I've upgraded to at Ati 9800 Pro and the edimensional drivers. The only issues the best implementation of these is XP. So I am upgrading to XP get this to work.
But I have not had time to complete, I'll post when I do. 😎

Have you tried this with a stripped down Benq LCD? Then I have to disagree with you.
3D works fine for stills on this set up and I have had it working for Postal2 and Mafia set at the most minimum of effect.
The minimal effect is not enough for my personal enjoyment. The the Nvidia drivers lack the sensitivity that is needed when instead of a 15 to 21 inch screen and being 20 odd inches away you are working with a 100 to 120 inch screen and are sitting 72 to 100 inches away.

I removed all the filters when I stripped the panel as the polorisation was stopping me attaining my goal of a 3d projector as when used with shutter glasses the LCDs in the shutter glasses polorise light as well allowing no light to pass...
Image quality on DVDs seems to be far more dependant on the video card used than anything else. "Lord of the Rings" is cinema quality on the ATI compared with the Nvidia Geforce3 with this set up.
I have no complaints and a great deal of wonder and complements when I show people a film...TV card and sports next 😀

Hello Again Unclebob:
"Thanks (same interests then) its me!"
This Is Great! Seems Were the only people interested in this here...
I Had all This Working With My Nec , But it Died, and I Got A sony 19 LCD... Can't Test Right now.
Using XP Pro, And Building Ace's Projector...
I Have Some Info, and will post it. This would be editing the registry, for proper Viewing with 100 " Screens...
I'm Working on Another too... Using Page Flip, and Using A Modified
Type of A (Zscreen) atached to the lens... I can Get DVD Movies To Play In 3D On The Fly, And I'm Very Happy With This...
I Don't Post Much, As Iv'e Been Very Busy With the Pats Games. I work For Them, So Now That The Bowl Is Over, I Have More time here...
Cheers,

Unclebob,
I really haven't tried the shutter glasses with the projector though I've got them (glasses and pj and Nvidia video card which should support the stereo drivers). I think I removed all filters (polarizers and microlenses or whatever they were) when I stripped down my Benq. There are still two polarizers left, and no TFT works without them. First one polarizes the light, then the TFT array modulates the polarization of the light so that the intensity of ligh output changes when the light goes thorugh the other polarizer. If the final polarizsation direction (horizontal / vertical) is the same as that of the glasses (when ON / letting the eye to see the image), I agree, the 3D effect will be obtained.
Btw. how is you pj built, is the light source in front or back of the TFT (regarding it's original position adn sides), does the light come and go as it did when it was monitor? Or have you turned the TFT around? I use the TFT as it was as monitor and use a mirror to mirror the image (and you don't need the mirror if you turn around the TFT). It may be that if you use it the other way the polarization is wrong for the shutter glasses. It may also be that left and right eye images will be swapped (maybe that's your problem?). Then you sould add an inverter circuit between the glasses and VGA output for the line which is used to control the shutter.

Thanks for responding. Stripped down the benq, build a case for the tft to fit on top of a ohp. Did not strip down the TFT and would not be sure how to do this as it all seems to be in one piece.
No issues involving polarisation. Perhaps because I'm viewing a projected image and not the tft directly.
Simple but effective.
