Full Version: Benq 567s circuit boards

Hi folks, I am in the midst of creating a (hopefully) sleek design to box my first projector. I am using Joe's Bakery as a template for the design but I am running into a slight problem. I would like to place my optics in a sled but the front of the circuit board on the 567 would run into the "angled" bottom of the box. That power supply board is huge! To anyone who has this panel, is it possible to separate the controller board from the power supply board? The CMV monitors have a wall-wart which would help placement significantly in my configuration. Any ideas on how to tackle this problem?

got a link to the origional layout? ms paint makes a quickie diagram maker too.

It is possible to separate the boards using 14-pin header and extension chord. It's just regular header stuff like on the IDE of floppy disk cable. However, I wouldn't use this monitor to make a projector. I did it but wouldn't recommend to anyone. The CMV CT-529a is much better.

Aer you basing that purely upon the contrast specs? I have heard differing opinions on this. Many people say that the benq actually gives a better image projected which is why I went with it; ironically the CMV is less expensive! Have you done a side by side of these monitors?

I have used both at my desk and in my projector. I think people have found FP567s v2 to be an excellent one. I have seen photos of dismantled v2:s and they were different. The other had older (v1) style TTL controller and two FFCs while the other was with LVDS interface (single FFC) and different controller. So the v2 with LVDS might have better panel too, v1 and v2 with the TTL interfaced panel are not that great. They have the ~ 10-15 degrees optimum viewing angle whereas CMV's best viewing angle is almost zero (maybe not exactly, I think it may be 5 degrees down but it's contrast is very good at zero angles).

Also the response time of CMV at midtones is far better, there's much less ghosting. Still I can't for an example view ice hockey perfectly, the spock can't be seen all the time clearly. It may though be the result of the deinterlacing algorithm used by my DVB viewing program(s), I use ProgDVB (with Cyberlink codec) and Hauppauge program which uses WinDVD codec. I don't know how Viewsonic N6 could work (anyone using CT-529a with Viewsonic: can you watch hockey games fine?).

Also the colors on v1 Benq tend to be easier to overdrive ("burn") whereas CMV with not too much brigthness and contrast gives perfect color depth (skintones look natural). These are the three main reasons for selecting the CMV, the price is (maybe) fourth good one.

Wow - thanks for the insightful feedback. It seems like you have compared the two monitors at length. I too was not overwhelmed by the image on the Benq (as compared to my laptop monitor - an old HP - nothing special). The benq rep said it was because laptop monitors are always manufactered to a higher specification ...

But, be that as it may be, the Benq is now mine and ready for stripping. It is good to know that that power board is seperable from the controller board via a 14 pin header. By the way, is it "like a floppy cable" or is it actually a floppy cable - I have a bunch of those lying around as spares! Thanks for your feedback.

Also, many on this forum seem to think that the benq is superior to the CMV in real-world performance (like joe from joe's bakery). I have a refurbed unit - I wonder if my unit is not up to par with the other benq's out there? I couldn't find any new ones to compare it with.

Sonic,
I also purcased a referb. 567 v2 from benq. So far all I have done is hook it up to my computer to test out and surf a little using it. I am really impressed and my wife now wants to get rid of our 19" monitor and get a flat screen.

My only worry in this whole process it when I get my nose close to the screen I can actually see the each pixel. I hope it isn't that noticable on the big screen.

Don't get e wrong, it looks good. Just not as good as my laptop monitor. It could have something to do with the laptop screen being a smaller size, but the colors just seemed truer on my laptop. It looked more like film. The benq was brighter though. I played a divx on the laptop ("Shattered Glass") alongside the benq and in the opening scene, there is a slow motion camera pan. On the benq it looked "jerky" - it was quite smooth on the laptop. It could have something to do with the dithered output of the panel.

Then again - my particular monitor might be junk. On the windows desktop (XP) the lettering has subtle shadows that are much smoother on the laptop than on the benq. I might be spliting hairs though ... probably won't matter on the final projection. Also, my sony trinitron flatscreen looks much better too.

Regarding the screendoor effect - my understanding is that it will be visible when you are close to the screen (all lcd projectors have this problem). It can be minimized by "blurring" the focus ever so slightly if you don't need a pinpoint accurate screen (for text, etc.)

I understand what your saying about the screendoor effect. I was listening to I-Tunes last night and set the visual effects to full screen and was totally blown away at the color and the detail. My wife and I sat and watched it for about 10 min. I just couldn't believe the detail it was giving off. I was sitting back about 3-4 ft.

Chances are that if the laptop screen is smaller than the monitor and it's the same resolution, it probably will look better...smaller pixel size. Some companies put some coating on their laptops to make them look brighter/sharper and whatnot...

Try looking at a Vaio S150...13.3" WXGA screen...beautiful....bright, wish I could use it in a PJ, or find an affordable equal that had a controller....oh well.
