Hey, anyone?

What happened to PM (private messaging)? Is it there or am I just blind. Or perhaps have our hosts pulled it, assuming we are talking privately about pricing info and recommendations about other dealers? http://www.avsforum.com/avs-vb/images/icons/icon12.gif

Has anyone tried to play BENQ 7700 with a HTPC (DVI - HDMI 720p 50 Hz) ?. Last night i saw the Benq7700 in a friendly home but we couldn't lock the signal in 1280x720 50 Hz via powerstrip (i live in Greece-Europe), and we REALLY need 50 Hz. Can anyone confirm this ?

If you are looking at the 7700 face on, with the lens pointing at you, which sides do the air get expelled/ taken in?

And what has anyone thought of gaming on the 7700 so far?

According to the manual, there are two intakes in the rear and two exhaust vents at the front.

The intake's actually on the left side of the projector (lens side) and there are two fans that exhaust out the front.

Enjoy!

Mike and Presenter.... I have read your review between the Benq and the Toshiba.... Very nice review and thanks for the effort. I was wondering how the third lesser heard of PJ in this rough price category fits in..... The Sharp Z2000. I have read some good and some bad news (kinda like most PJ reviews). Was wondering how it holds up to the other two?

You cannot dispute the evidence of an intelligent creator! Take a glass, some milk, some chocolate syrup and set them all on your counter. Now call me when it becomes chocolate milk all by itself.... Also, I want to be there when you drink it :-)

Engine, my vga/bnc adapter didn't work at all. The dvi - hdmi is obviously far better since it doesn't convert digital to analog and back again.

The 7700 will not do 50 hz. It seems the MT700 can.

The sharp z2000 is a fair bit more, and only has a 1 year warrenty. It compared well to the 8700, but the 7700 is apparently quite superior to the 8700, so it might be hard to justify the extra price of the z2000.

man, If this projector would only have a longer throw. I need a 110" diagonal screen at 16 feet back - looks like this proj will only go back 14.3' to give a 110" screen - BUMMER

I was planning a 110" screen at 14 foot, but this thing looks so good I am going up to a 133" screen, just cause I can't get a 144", which is where it really looks best. Unless you have some good reason for a screen that small.

Art - The PM link is in the subject bar, just below the "Alliance Member" Ads (& just above the thread listings).

It's hidden in plain sight.

Sorry I couldn't see you & Mike - I would have loved to have seen the comparison. Thanks to both of you for the info.

Have you tried to connect 7700 via hdmi with htpc in 50 Hz?
Why do you say that it can't sync in 50 (is it in the manual?).

I sincerely hope it syncs with 50hz, otherwise it's DOA in Europe in my opinion

Benq PE7700 does sync 50Hz via hdmi. It shows 720p50 in lower right corner, when I switch my Nvidia 6600GT to 1280x720@50Hz

Could someone post the dimensions of the mounting holes on the PE7700?

I'm trying to plan ahead so I can retrofit my old Infocus mount with a new plate.
I believe I read that the holes are 6mm, has anyone had any luck finding suitable screws at Home Depot or Lowes?

The pattern's not square, so it's a little difficult to dimension it. I got 6 mm bolts at Lowes, but then got longer ones later at Ace Hardware, where there's a larger selection.

Enjoy!

Greetings Todd_zilla

If you are running 100" or more diagonal, I'd go for a high contrast white like the Firehawk. I'd go high contrast gray for under 100", as the smaller the screen, the grayer the blacks. (Actually 100" would be the "go either way" size.

Also though, I believe (not sure) that the Firehawk will do better rejecting side ambient light, but that is a guess.

If you go very large (say 120"+) and your viewing angle is narrow, some might suggest a high gain screen like the Studiotek. (these are all Stewart brand screens, which are premium priced. Dalite and other offer "not quite as good" but similar screens for less.

(To give you an idea, Dalite's high contrast white has a gain of 1.1 vs 1.3 for the Firehawk, etc).

I myself am replacing my old 140" dalite matte white, with a 128" motorized Firehawk, which arrived yesterday and is going up next monday. (I am excited!) -art

There is another review you can give us Art.
So, what are you doing with the 140?"

Art - are there (roughly) equivalent materials for the Da-Lite screens? I'm planning a 7700/MT700 PJ with a 133" screen and have been struggling to find useful info for screen selection. I posted an inquiry in the screen forum, but I don't think there is much traffic there. At this point, I'm considering a Da-Lite "perm-wall".

Basically, I'm planning a 133" screen at 15' throw in a 16 x 20 room with good light control. There are, however, eggshell cottage white walls and ceiling which I understand could affect the equation. Thanks for any advice you may be able to provide.

With DaLite, I would either go with the High Contrast Cinema Vision or High Contrast Matte White. Both have a 1.1 gain.

Enjoy!

Thanks for the info Mike. I was looking at the Da-Lite cinema-vision just last night, and it sounded like it might be a good fit.

Greetings Jack?

That's a big screen - my 140 is very marginal with a matte surface, and "off white walls". the 7700 has an extra 100 lumens but that sure isn't much, and the contrast enhancement stuff does more for bringing out low level detail than dynamicing up the brightness. I expect my new 128 Firehawk, which is high contrast (hc) and has a agin of 1.3, will buy me about 40% more ft candles than the old screen. But I'm also taking my walls to a dark rust color, which probably will elmiinate about 90% of the reflected light.

Based on my experience, you will definitely want a high contrast "white screen". In the Da-lite lineup, you'll want to consider either the Cinema Vision, or the HC Cinema Vision. or the HC Matte white. Problem is - I can't keep them straight as to which is availlable on fixed screens, which on motorized, etc.

Anyway, I would think first, the HC Cinema Vision (assuming you are sittting within the left and right edges of the screen. You get slight gain, slight rejection of off angle ambient light (walls - in your case), and a gain of 1.1. You can use all of the above. (If you can darken your walls - 30% of the theater experience is that you are only aware of the big screen, the rest of the theater basically appears black, or close enough you dont notice them.

The straight Cinema vision will do even better in terms of rejecting ambient light, and giving your image more overall brightness. The BenQ 7700 has really good contrast and on a standard 133" the dark gray that "blacks" create should be "black enough" to skip the HC version The extra gain might help you.

However if I had to guess, I'd pick the HC Cinema Vision. The last two on your list from dailite would be the HC Matte White, but I don't think that one is availlable on fixed wall. It is similar to the HC Cinema Vision, but I am lead to believe that the CV is better.

Lastly you could go with a higher gain screen (say 1.5 or so) but I don't know off the top, which one that is. Anyway the HC CV and the CV, as well as one of the HC mattes, should be available on the perm wall, or if you want to spurge on nice trim (a lot more $) the Cinema Contour screen, (similar name), with Pro-Trim. Avoid the Imager, which is iffy at large sizes since it uses velcro to adhere the surface to the frame. Certainly the perm wall makes it affordable.

Got it? -art

Thanks art! Sounds like either the Cinema Vision or HC Cinema Vision are the screens of choice in my situation. I've still got a week or two to study this. I do appreciate the advice from everyone.

Has anyone tried the Carada screens with this projector?

They have a 1.4 gain white and 1.0 gain white.

I actually went with a 120.5" SliverStar XWF screen. It took up all the space on the wall and had it been one inch bigger either way, there is no way it would have fit in my basement. I have been told it will be an excellent screen once I fire up the PJ on it. Speaking of which hopefully the second batch of the 7700s will be in next week. Must be doing well since everyone seems to be backordered...

Yep, I backordered mine this week, Joe. I have another slightly-OT (but specific to this projector, and the MT700 for that matter) question:

Is anyone going to do a constant height setup w/2.35:1 screen with this projector? If so, which lens, and have you received it and gotten it working yet? I'm waiting on buying a screen until I build my dedicated HT and can hopefully get a lens and 2.35:1 screen.

Two side notes to this:
- The Vutec Silverstar doesn't come in 2.35:1, does it?
- Will the short throw be a problem? Maximum zoom (ie max throw distance and max throw ratio) is 1.78 for this projector, according to the PC calculator... is this too short for a horizontal stretch?
