re: lens-shift/keystone. I'm preparing my attic for a theater, and was going to get the optoma 33. Based on the pictures/dimensions from the optoma calculator for ceiling mount, it said to allow for 9.5" from center of lens to top of image. Assuming I can hit that exactly, do I need to worry about keystone/lens-shift? Or am I wrong in assuming if I set it up exactly as they recommend, that the image won't be distorted?

Does anyone know if there are any projector that has rabbit ear antenna inputs? Is there such a thing?

I've never seen one. You'd put the rabbit ears into something else, and that would go to the projector.

Well lets face it....everything is a comprise. Otherwise would have separates and custom built rooms with sound panels.

With a DIY home theater I don't think "the best sound quality" is the only factor. A receiver in these rooms delivers more than the audio. So....I think it fair to look at reasonable features, connections, etc.

Of course don't get junk...and make sure they reasonably match with your speakers.

I'm thinking I will try the switch first and make sure that the projector through RGB is actually a problem. Now I have to upgrade a 5 year old computer. :lol:

Dave,
My Mac does have HDMI, so no experience with the PC input. The Mac did try to sync at 1080p50 instead of 60 for some reason, and the PJ didn’t like it. I had to go in and choose the connection manually. (manually? the horror!) But come to think of it I really haven’t played video from the Mac, yet. I will soon I’m sure, it has one of my TV tuners and there are 2 shows recording there instead of on the Tivo. Oh, I still have to try playing a PAL DVD from my player, too. Those get sent as 50Hz from my Denon and the PJ should be able to play it, but the Mac failure at 50 is curious.

I do have a Monoprice HDMI box as my receiver is well older than HDMI. I’m worried it is the problem with my BDp sync that I detailed above, but I haven’t done proper troubleshooting on that, yet. But it does seem to work fine with the Mac and the Tivo. I have pretty good short cables from the sources to the switch, then a thick cable running up to the PJ, all Monoprice.

Sdallnct,
Actually, I didn’t say that just for you. (a little, sure ;)) I’ve been a bit worried that I’m blowing money on a minor upgrade for no real reason. Stopped worrying about that yesterday watching the Packer game, and after a BD movie on Sunday. Very glad about the res, now.

Does your Onkyo have preouts? You could still use the HK amps. I was all ready to upgrade my audio first since that is my first area of concern usually, set to drop about $1500 (my estimate) on the Emotiva XMC-1 preamp, with amps to come later. Then it was delayed…for over 3 years, with specs changed dramatically about 4 times in that period. It no longer resembles what they originally claimed. Part of that was their silliness, part HDMI craze, part Cirrus Logic which has been a bane to the HD audio community for the last few years (just ask Cary Audio). I have been happy with my receiver, it can run my Klipsch (high efficiency) very well and it is still running perfectly over 10 years later. It’s hard to justify an upgrade to separates when I can play at reference level with a receiver, cleanly. Not that I do play that loud.

You need to install it perfectly per the specs, then no distortion or keystone needed. Sounds like you have it understood just fine.

It's just bizarre that basically every <$2000 DLP maker won't include any shift, and makes such large offsets necessary. But as long as you have space, it works.

I looked at the 3 (optoma, epson, panasonic) in that range and none have lens shift. Need to go up to the $3k range for that, and there aren't enough other benefits in that range to justify the extra cost for me. I've got the room and the patience to spend the extra time to hit the mark exactly, thanks for confirming my thoughts.

Re: Might be time to upgrade the projector. Any new developments?
 
Not sure which you are looking at, but the Panny AR100 is $1500 or less and has shift in both directions. Epson 3010 or 8350, too, IIRC. Those are all LCD, where they do put in shift, for whatever reason. But, yeah, it isn't necessary if you have the space. Then you can buy on tech and other features that you prefer.

I know that I don't have any problem from the BD player or the TV. Everything is bright and smooth. Are you saying that you were able to change the computer settings in some way to make the output 60fps? I wonder if I can do that, and if so.....how.

Spiky 01-17-12 02:05 PM

Re: Might be time to upgrade the projector. Any new developments?
 
Just went into the prefs and picked the 60Hz version of 1080, it gave me all sorts of choices. Can't guarantee your software/graphics card will do exactly the same, but...

System Preferences: Displays on OSX
Control Panel: Display on WinXP. (I assume similar on Win7)
Or you might have a direct control panel for your graphics card on Win. I have some Intel control panel in my work computer. It will call it Hz, not fps, same thing.

kvrdave 01-17-12 02:16 PM

Re: Might be time to upgrade the projector. Any new developments?
 
I will give that a try, thanks. Looks like a new video card with HDMI out is only $30 so I'll likely do that as well, simply because the HDMI vs. RGB would be worth it.

kvrdave 01-17-12 02:25 PM

Re: Might be time to upgrade the projector. Any new developments?
 
Checking it from work with Logmein, it appears that I was at 60Hz, but that the display was set to the resolution of the old pj. I just put it up to 1080 and I'll see if that jars something loose tonight.

are those 1080p 3D? those are the 3 I was looking at. Maybe I ruled them out for other reasons... been a couple months since I settled on it

Spiky 01-17-12 02:47 PM

Re: Might be time to upgrade the projector. Any new developments?
 
All 1080. Only the 3010 is 3D. Either that or the HD33 is probably a great unit for 3D for that price. I didn't mean to question your choice.

Ha! I know...and yea...I believe 1080p would be a worthwhile upgrade. My front row is right at 10.5 feet and a 94" screen. While I find it good for BD, everything else I move to rear row.

And I know it is getting close to time. My HD70 has served me well. Funny it was the first 720p pj to retail for under a grand. Now just a few years later you can pick up a nice 1080p for under a grand. My 2nd bulb in it has over 3,000 hours on it and I recently upped the brightness a notch or two. I get my annual bonus that is my "blow" money in early April, so I likely hold off till then. But I 99% sure I can make the Mit HC4000 work and be able to get it for a grand by then. So essentially it would be $700-$750 (if you take the money spent on a new bulb). Tho by then they may have a new model for only a couple hundred more...so will see. I just love DLP....and very unimpressed with LCD (I know, I know, it more about the individual units now), so I don't see switching over.

I doubt the Onkyo has preouts. It is a really low end mode...the 508. It is fine. I'm not worried about it. I like you, was just really happy with the warm sound of my old H/K. But I was the only one that noticed and truth be told, can pretty much only tell on concert video's and such. I can't honestly say I can tell a difference on Movies or watching a football game.

Edit: Just spent some time reading about the Epson (LCD...the horror). I do like that it is brighter (I would expect LCD to be), but what really caught me is how quite the unit is. Impressive.

It will simply tell you if you can have the size you want at the distance you want. It shows a range of about 92" to 184" diag screen at 18' throw with the AE7000.

How I do determine if the projected image will clear viewers' heads? Also, do you all have an extension cord permanently connected to your projector? I would imagine projectors' cords are nowhere near long enough to reach an outlet.

Damn it. You guys have me shopping for an upgrade too now. My Mits HC1500 is on it 3rd lamp and I'm now looking at the Mits HC4000. I don't want or need 3D but the increase from 720p to 1080p plus longer lamp life has me itching to upgrade. I just replaced the lamp this past summer so I have until next year until it will need another at which point I'll pull the trigger on a new PJ. So that gives me too much time to shop and compare. Its gonna be long year now that the thought of upgrading has been implanted in my brain.

I had one put in near where it was mounted. Otherwise it is tough to live with an extension cord. Honestly, I never thought about clearing the newer's heads because I sit almost directly under it, but that is definitely something to look into. That would suck if you came out on the wrong side of it.

:lol: The bug spreads like wildfire.

I think I need to commit to changing the bulb every year, whether I think it needs it or not. It makes such a big difference, and otherwise I tend to not notice it getting dim. And mine definitely will since I use it so much. My last panny bulb I let go to 5,000 hours and it was milk white on the lens.

You can probably get a couple-three hundred for an old PJ with not too much lamp life used on it. I know!! Still not helping!

Well, you could grab string or something and stretch it across from where the bottom of the screen would likely be and the lens. Move it around for various possibilities. And yes, I have a drop ceiling with many wires running in it, including extension for power to the PJ.

I'm not sure I understand what you mean. Are you planning a 2nd row of seating? For what I did and put blue painters tape where my screen would go and then use chairs with phone books to see how it would work. It helped determine my riser height as well. Tho I wish I had make it just a touch higher.

Yea...the HC4000 is on my short list. I'm pretty sure can make it work in my room. I believe the lens off set is less than my HD70. I have no need for 3D either. Until it becomes good with passive (cheap) glasses I have no interest in trying to have 10 pairs of those expensive glasses laying around.

No, just one row. If I hung the PJ from the ceiling and tried to utilize the whole length of the room for throw distance, the PJ would go behind the seating because I wouldn't want the seats to be 19 feet away from the screen. I'd like them a few feet closer unless people's heads are going to partially block the light from the PJ.

Why so far back? And depending on zoom could be ok.

See, I just don't understand enough about projectors. I assumed in order to get the biggest possible image I had to put the projector as far back from the screen as possible. Does zooming it mean I can put it closer to the screen and still achieve the same size image? Does zooming it make it blurrier (like zooming in on DVD makes the picture ugly)?

Spiky 01-17-12 11:34 PM

Re: Might be time to upgrade the projector. Any new developments?
 
DVD zoom is digital, electronic. This is also the definition of crap.

Assuming a decent lens, optical zoom is far superior. Most PJs, maybe all, have zoom. As with any zoom lens, it would be better to not be at the far ends of the zoom for best pic quality. But for 90% of the range, the pic really should not change at all, maybe 100% depending on the quality. A common issue is the brightness goes down at maximum zoom.

Try the Projector Central calculator, it shows the zoom range for a certain screen size for a specific PJ. You can adjust the settings in the calculator to see what kind of location you can use. Try to keep it out of the last 5-10% of each end of the range when comparing distances.

Probably the biggest issue is one of brightness. Most less expensive projectors have trouble that far away. But than you need to clarify what you mean by "biggest possible image". What exactly are you talking about? Most max out their image at about 120-121 inch measure diagonally. I'd say 100" is about the most common. That is a damn big screen considering just a few years ago a 50" plasma was really big and still considered a good size.

Don't forget you can also "help" with screen size with seating distance assuming you have a quality image. I use a 94" screen. But my front row is just 10.5 ft away. It "feels" like a bigger screen. My 2nd row is 12.5 ft away. Of course the closer you are the better image you need. My projector is right between the two rows about about 11.5 feet. And it has a really small zoom. I choose this as it is roughly in the middle of the zoom range for the size image I wanted. Plus it makes messing with the proctor (which you rarely have to do) easy since no seats in the say.

When I go to 1080p I might up to 102" or so. You can see in my image in my signature I'm constrained by the two doors on either size. But I have a couple inches to work with and can make the black boarder a little smaller.

But again, Anything around a 100" is really big (and good). 120" like many get is getting huge. Which again, can be good. But I think that is reaching the max of many of the inexpensive projectors we are talking about around here because of light level. Most good reviews on projectors will at least mention a projected max size.

Edit: Just as an example, the review on the pj I'm looking at mentions it can handle a 120" screen.

http://www.projectorcentral.com/mits...tor_review.htm

And note how they mention placement, lens offset and throw. Better reviews will mention this as every projector is different.

"The HC4000 is a 1080p DLP projector with a great picture, but not a lot of bells and whistles. It has a bright cinema mode--bright enough to use it on a 120" diagonal screen in a room with decent light control. The projector has a 1.5:1 zoom lens. But it lacks any form of lens shift and has a steep upward throw angle offset of 33%. For a 100" diagonal image, this means the bottom edge of the image will appear 16" above the centerline of the lens. This makes it a perfect choice for a ceiling mount, as it will not require the use of a drop tube in most circumstances. A low table mount between the seats would also be simple to set up. The zoom lens gives you some flexibility in throw distance, so it's a great option for folks with complicated ceilings; for example, I have a ceiling fan in my theater, 'conveniently' placed in the ideal spot for a projector (I still have to thank the builders for that one). Thanks to the HC4000's 1.5:1 zoom, I can place the projector in front of the fan and still get a 100" diagonal image."

Exactly...give yourself room to work with the zoom. Not only for quality which is a good enough reason, but also to give yourself wiggle room in case you are a little off on your measurements.

I'm looking at the JVCs.

There are new models such as the DLA-RS4800 and DLA-RS55 (http://pro.jvc.com/pro/attributes/PR...omparison.html) and somewhat older models, such as the DLA-X3 and DLA-X7. Then there are the DLA-RS series models. It's quite confusing.

The 4K DLA-RS55 looks really nice from the little bits of info I've been able to find, but it's pretty expensive. And then there's the Sony VPL-VW95...

My 2nd row is 12.5 ft away. Of course the closer you are the better image you need. My projector is right between the two rows about about 11.5 feet. And it has a really small zoom. I choose this as it is roughly in the middle of the zoom range for the size image I wanted. Plus it makes messing with the proctor (which you rarely have to do) easy since no seats in the say.

When I go to 1080p I might up to 102" or so. You can see in my image in my signature I'm constrained by the two doors on either size. But I have a couple inches to work with and can make the black boarder a little smaller.

But again, Anything around a 100" is really big (and good). 120" like many get is getting huge. Which again, can be good. But I think that is reaching the max of many of the inexpensive projectors we are talking about around here because of light level. Most good reviews on projectors will at least mention a projected max size.

Edit: Just as an example, the review on the pj I'm looking at mentions it can handle a 120" screen.

http://www.projectorcentral.com/mits...tor_review.htm

And note how they mention placement, lens offset and throw. Better reviews will mention this as every projector is different.

"The HC4000 is a 1080p DLP projector with a great picture, but not a lot of bells and whistles. It has a bright cinema mode--bright enough to use it on a 120" diagonal screen in a room with decent light control. The projector has a 1.5:1 zoom lens. But it lacks any form of lens shift and has a steep upward throw angle offset of 33%. For a 100" diagonal image, this means the bottom edge of the image will appear 16" above the centerline of the lens. This makes it a perfect choice for a ceiling mount, as it will not require the use of a drop tube in most circumstances. A low table mount between the seats would also be simple to set up. The zoom lens gives you some flexibility in throw distance, so it's a great option for folks with complicated ceilings; for example, I have a ceiling fan in my theater, 'conveniently' placed in the ideal spot for a projector (I still have to thank the builders for that one). Thanks to the HC4000's 1.5:1 zoom, I can place the projector in front of the fan and still get a 100" diagonal image."



Exactly...give yourself room to work with the zoom. Not only for quality which is a good enough reason, but also to give yourself wiggle room in case you are a little off on your measurements.

Man, there's a lot to consider.

Meh...Projector set up is not plug and play like a TV. However, it is a one time event. Spend some time on research, than a weekend of set up and you are done. And have an awesome set up for you to enjoy.

But, surely you have some idea of what you want. Number of rows or number or seats. Surely there is some limit on size of screen or exactly where to mount your projector? Or maybe you are limited on where you put your seating? Or where power is for the projector. One you have decided on one or two of the variables either by force or preference, the others will start to fall in place.

For example, if you use my room as a test, a little thought and things fell into place quickly. The screen had to go on one of the two short walls as one long wall was all windows and the other built in book shelves I wanted to use. If I put the screen opposite the doors than the two doors would have limited the number of seats. So the screen pretty much had to go between the two doors. Once that was decided I figured the size I could put there and measured that I had room for two rows of seating. Then determined what 2-3 projectors were in my budget. Then which one had the zoom and offset that would work...and the rest is history.

Yeah, it isn't quite the same as buying a LCD and throwing it on a table.

But there is one more thing to consider:
100.
Inch.
Screen.

Any more questions, just ask. :)

Re: Might be time to upgrade the projector. Any new developments?
 
Well, I know which wall to put the screen on. I just don't know if the pj should/must go all the way against the back wall or maybe more toward the middle of the ceiling. I suppose putting it against the back wall means I could run the cables up the wall (or if I'm really industrious, try to hide them in the wall... but I'm no carpenter). Hiding the cables if it's ceiling mounted would be a bigger challenge because the second story of my house is on top of the room where I want the pj.

As far as seats go, just one row will do. I don't want them against the back wall as I think 19' would be too far away from the screen... unless sitting any closer than that would make the screen look fuzzy or pixelated.

As far as screen size goes, bigger is always better. If I can fit a 120" screen and it looks sharp and bright, that would be great. But I guess if the pj doesn't output enough lumens, then I could end up with a washed out image from the pj being too far away. I do most of my viewing at night, and there are black out curtains on the windows, so at least ambient light won't really be an issue. Most likely I'll stay away from the $1,500 and under projectors and go for something around $3K. They all seem to have much better contrast ratios, light output and lens shift. The Panasonic AE7000U is on sale through 2/7/12 for $2,600 at projectorpeople and visualapex. Very tempting.

Well there you! You have already figured out a bunch of it!! 120" screen will be good. You shouldn't have to worry to much unless you try to go much bigger (but I would think ceiling height would begin to be a factor). And that is a good PJ, so again, you are likely set there or least that type of PJ.

I wouldn't put the pj that far back. And without looking, not sure it would would that far. 1st thing I'd try is to see if you can run cords in the between the ceiling and upper floor. Might be pretty easy as there likely won't be insulation in there. Of course, might not work at all if the joists are not running the right direction.

How high is the ceiling? And do you plan on painting it? Drywall is not that hard to work with. Assuming you put the ceiling in the middle somewhere, taking down and putting up a couple sheets of drywall wouldn't be that hard. Or hire a handy man to do it. And if your painting the entire ceiling anyway...well...

Or you can get some of that track stuff. Tho that stuff is sometimes expensive. But it is paintable. But if your spending $3,000 just on projector, I'd seriously consider just taking redoing the drywall on the ceiling. Even hiring a drywall guy, I wouldn't image they would charge even $500. Than you can run the wires yourself. Or heck get an electrician to do it and add an electrical plug in the ceiling. Again it would be an electrical minimum charge, probably $250 or so....

You can do this all yourself. I didn't know anything either. Running the wires, how to mount, anything. The guys here were really helpful. And doing a little Google search and such....I ended up building my own screen, my own mount, running all my wires (the only cop out I did was just use an industrial extension cord instead of installing a plug - but that was lazy, I looked up how and wouldn't have been that difficult).

All this talk makes me miss my projector - I used to chime in on these threads - like kvr I had an Infocus X1 to start. I went to an Optoma HD72 after that. Miss my projector. :(

I had to move to a rental home though and hanging the screen and projector wasn't practical in the finished basement in the new house.

I switched to a 50" Panny plasma early in 2011 after the move...the blacks are nicer than my old HD72, and I don't have to worry about ambient light nearly as much...but I miss my 105".

I was a DLP guy. At my old house, it was easy to put the projector up high - we had an arched ceiling - and get the picture just right.

As far as mounting it - The biggest thing with putting it on a stand on the floor (I did that with my X1) was that if someone bumps the stand or something you have to re-adjust the projector - I spent a lot of time fiddling with it. Plus people inevitably put drinks or other stuff on the stand - I was always worried something would get spilled on it.

If you are worried about lumens, look at the LG Spiky and I just bought. Never seen a projector this bright.

Also, to compare, I have complete light control, and the Panny 900 was plenty bright at only 1300 lumens. That is with a 122" screen and the pj mounted about 13' back. The AE7000 does have more lumens than the 900 did, so it ought to be plenty impressive.

:lol: I remember getting into it because the cost of plasmas at the time was so freaking expensive, but that is what I was looking at. I couldn't imagine going with 40" though, and for about half the price I had the X1. Nice, heavy screen door effect and all. It's amazing how much better they have gotten. But I remember those old threads.

Yea...the HC4000 is on my short list. I'm pretty sure can make it work in my room. I believe the lens off set is less than my HD70. I have no need for 3D either. Until it becomes good with passive (cheap) glasses I have no interest in trying to have 10 pairs of those expensive glasses laying around.

You should do what I've finally done. I started a donation jar. It was even my friends' suggestion! They said they wanted their own glasses and would be willing to contribute to them. As the jar fills up, I'll take it to Coinstar in exchange for an Amazon gift card and order as needed. :D

As others have said, using the zoom shouldn't affect the picture quality. Just remember that you're have to adjust the focus after adjusting the zoom.

And I know that this is sort of bringing up an old topic, but I believe my inexpensive, under $1,000 Optoma projector has some type of lens shift. That's the ability to just move the image over, right, either vertically or horizontally? If so, then yes, mine does have that ability, and it's quite handy.

Ugh. I'm always fiddling with mine. Each time I put it up, it feels like a new experience. Since I only use my projector outside, I take it down after each use. It's way too humid where I live to leave it up all the time. But because of always taking it down and I'm sure just the outside conditions, I'm always fiddling with it trying to get it *just* right. The latest issue I'm having is that the image looks slightly crooked. I have a mount similar to that spider-looking one that was posted earlier. I think I need to adjust one of those arms. It must have gotten moved or something. I need figure out how to get it straightened out again.

Its unlikely your Optoma has lens shift. I know of no inexpensive DLP that have lens shift. I don't know exactly why. Must have something to do with the chip. Many a low cost LCD do, but none of the DLP's do (least none of the true, highly rated, inexpensive HT one's).

You do have keystone adjustment. Which can help, but at the expense of resolution. Tho there is often fighting at HT boards about how much. Many say if you just need to "touch" of keystone adjustment, do it. The resolution loss would be unnoticable. But if you really have to do a lot of adjustment, move the entire projector.
