I need a small (<10" wide) 1080 Projector with ZOOM

post #1 of 14
Thread Starter 
I purchased the PA75Ua and while it looks great, it projects a 160+" image that spills all around my 120" screen when mounted in the ONE SPOT it can be in my living room. (yes, NOT Movie Room; my LR CONVERTS to a nice big MR with KITCHEN) I actually prefer it that way, but it does present aesthetic challenges that a MR does not have) smile.gif

Anyway, anyone got any ideas? The PA75 is certainly feature-rich enough for me. If I only had a ZOOM!!!

anyone..? anyone......?

That's a 120" wide or diagonal screen?

16:9 Aspect Ratio?

What is your exact lens to screen distance?

Not that any of this matters if you didn't properly plan this out.

120" on the diagonal, 16x9, 162" - 164"

This is a projector lift that I built into my ceiling. It lowers down so that the projector is clear of a large beam in the line of sight of the screen.

The 162" - 166" was built to spec to my original projector (an old inFocus). When it died, I bought an Optoma HD 65. I was able to use the zoom on it to adjust it perfectly. With regard to the comment about whether I planned it out properly, I guess you're right. If my job was AV Design, I guess I didn't really plan that well. But as an video hack, I simply thought that 12 yr old and 6 yr old technology worked well at that distance so today's technology should be a snap. I guess that was poor planning.

Despite my poor planning, if anyone has any advice on what I can do NOW, I'd appreciate it. smile.gif

Again the problem is that due to the width between ceiling slats, the lift only supports a projector that is 11" wide or less (not <10" as I indicated on this post originally-I re-meaured)

Here is a list of the projectors which can hit that screen size, from that specific distance...


There is not a search parameter which can knock down to the width you want, but this model comes close at 11.2" wide:


All these projectors really should be inverted when mounted for the least amount of keystone to be used.

The Acer is a really close fit, but the throw distance can only do 13' (156") to a 120" diagonal screen, not 13.5' (162") to the screen...

The list of 720p projectors which are close in size is better... The list is shorter, but the size is a lot closer across the board:

You may also want to look at 1280x800 projectors which may be more business oriented, or not, but have a pretty wide selection of models, and many are smaller in size:

ie: http://www.projectorcentral.com/Optoma-W304M.htm

The space is terrible, but I get that you are stuck in your situation as it is unless you choose to rework the space so it is a box that hangs tight to the ceiling, then drops, which would really open up your options, but leave a white 'box' on the ceiling.

Great info. Thanks. I have an Optoma HD65 which works great now. It blew a bulb so I went to the site and searched for small form factor 1080 PJ's. When I saw some at around $500. I realized the bulb for my HD65 will cost $150 or so and I can sell it w a new bulb for around $300 ($150 net). So that's when it occurred to me that I could upgrade to 1080 for the net price of 2 more 720 bulbs. Seemed like a no brainer.

Anyway, after looking at more prices I think 'll mount the LG PA75U just under the beam you see in the pic. Then I'll shut the projector lift and live with this new setup until the high end 1080's come down in price.

Since the PA75 has no bulb, what is the expected maintenance on it?

After taking a closer look at my projector lift and the vertical motor that lowers it, I can actually make a couple modifications and just barely squeeze in the InFocus IN116. This looks like a great projector. Is it as good as it appears? What compares to it in the $500 range?
post #8 of 14
The IN116 is a business class projector, not a home theater model. This likely means it has a 2x color wheel, perhaps with a white segment which is bad.

It is lower in contrast than dedicated HT models and has higher noise levels.

It is 11.8" wide... so if that works, then this would work and would be my recommendation:


This is a brand new projector designed for home theater. Bright, at 3,000 lumens, but HDMI 1.4 compliant, and a 18,000:1 contrast ratio which means it likely can be tweaked a great deal. As far as I can tell it is the replacement for the venerable HD66 from Optoma.

It is 11.3" wide, and can hit a 120" diagonal from 13.5' away, which is what you need.

This model is about as 'ideal' as they come for your setup and is designed for home theater use.

very cool! I have 2 concerns:
1. This PJ is native 720. The others I have been looking at are native 1080.
2. This PJ had 1280 x 720 res native. the others are all between 1280 x 800 and 1920 x 1080

On the other hand, this PJ has 18000:1 contrast which is WAYYY higher than all the PJs I've been looking at in this price/size rage.

So is the native res less important than contrast ratio?

Thx so much for the help!!

If there is a 1080p projector that you can use which works from the distance you want and your budget, then great. The BenQ W1070, Optoma HD131Xe, etc. are all solid models, but they run $800+ and they are the cheapest 1080p models out there, so I'm not sure what you've looked at specifically that is 1080p. Please provide links if you have them.

Certainly, 720p native is a better option than 1280x800 since that isn't a A/V resolution, but designed for PCs. Better to use a 16:9 screen and stick with a 16:9 projector if you can.

so 1280x800 is NOT as good a 1280x720??

All of the ones I was researching were 1280x800 but climbed to do native 1080. This one looks reasonable for what i guess MUST be native 1080:

Acer H6510BD $699 $650 1920 x 1080 3000 10k:1 1.07B (30bit) Man/Dig
post #12 of 14

Any PJ claimed 1080p and any resolution below 1920x1080 is down-sampling the pic(much the way many flat screens claimed 1080p @ 1366X768 which isn't 1080p, but WXGA). I had a 1280x800p projector and if using an HTPC it would be fine for anything up to 720p, 1280x800 is a PC resolution and a 16:10 ratio. 720p material will have bars at the top and bottom. They generally don't have any sort of advanced calibration and lack many of the features of projectors that are only $100-$200 more. The HD180x(if it fits your location and budget) is a good suggestion(and can be had for ~$480).

If the projector is designed for home theater use primarily vs. business use, than 1280x800 can be very good, but most of those projectors will be designed for business use. This means that it has weaker video processing, likely a slow color wheel, poor color, poor black levels, lower contrast ratio, and perhaps is noisier. To gain lumens (brightness) it sacrifices image quality. So, you have to read reviews and be very aware of what you are looking at.

Don't confuse yourself on this.


1280x800 is 1280x800. 1920x1080 is more than 1280x800 so no projector can NATIVELY create a 2 million pixel image when it only has 1 million pixels to work with. It must throw out 50% of the information. So, native resolution is all that matters. Whenever you read 'supports 1920x1080' or similar, then that's smoke and mirrors. What you want to know is the actual native panel resolution, and 1920x1080 will always trump 1280x800 or 1280x720 as far as resolution goes. There are still many other factors which matter including contrast ratio, color accuracy, motion processing, shadow detail, etc.

The Acer is very entry level, and not one of the brands I would use or recommend, but it certainly has been well used by others. Just because I don't recommend it doesn't mean that it is terrible. I'm just not a person who quibbles about $100 or $200 to go from a questionable company to a more established company. BenQ and Optoma are both projection industry leaders. I tend to stick with their products and quite often the reviews support that. Dell, by example, often discontinues support for a projector as soon as possible after manufacture. Panasonic may support a projector for a decade or more after manufacture. These projector manufacturers also have a far longer history of making quality product vs. certain other manufacturers. But, you can read plenty about the Acer right in these forums if you want to know more and it is in your consideration list and works in your space.

Good stuff. Thanks. This all started when the bulb to my Optoma HD65 went out. It seemed that I could re-sell my Optoma and buy a new 1080 PJ for a couple hundred net (versus spending $80 to get a new bulb). Anyway, after all this discussion, I ordered a bulb. I will re-visit this topic when the new bulb goes out. Thanks again!
