If you play around with the various variables in the ProjectorCentral calculator, you will notice that for a given screen size, the offset is constant, regardless of the amount of zoom. I can confirm that is correct. (offset doesn't change w/ zoom).

One other item to note - for a given screen size (100") - for the Viewsonic, the available mounting range is 10'2" to 15'7". Note that the offset stays the same. Also note that for the 100" screen size, the brightness of the image will vary between 34fl at 10' and 25fl at the 15' mounting point.

For comparison, the Epson 8350 is much more flexilble in its mounting options, but that isn't necessarily a good thing. For a 100" screen with the Epson 8350, the zoom allows mounting anywhere between 9'9" and 20"9". Quite a range. However, the Fl of the image varies from 34Fl at 9'9", to 14fl at 20'9" is a very large change. In the case of the Epson, you probably would want to mount the projector based more on desired light output, rather than the easiest installation point.

Depending on your room and viewing conditions (lights, windows, wall color), your desired light output from the projector may dictate the mounting position more so than other factors.

One last consideration - I believe the ProjectorCentral Calculator is pretty accurate with regards to the math calculating throw distance, zoom range, and offset. However, the Fl calculations are taken straight from the manufacturing supplied information as well. You should factor in the fact the Fl output of a projector varies greatly over its life and depending on the calibration/mode (eco, full brightness v. theater selection).

CoderGuy, an owner of a Viewsonic Pro8200, and frequent poster, has a link in his signature to a calculator that has a little more real-life calculations for the Fl you can expect out of a projector.

So if all else is equal, ideally you want to mount your projector near the front of that mounting window, right? This way your ideal image calibration will use less brightness than if it were at the back which could lengthen the overall life of your lamp, correct? Again, all other things equal. Seems like a basic idea so I want to make sure it applies.

That is generally true. Unless perhaps you are in a light controlled environment, w/ a high gain screen (although you probably wouldn't have a high gain screen in that environment).

Some owners have installed a Neutral Density filter because the projector is too bright in their installations. I suppose in that case, mounting the projector further from the screen might be desirable. However, in the case of a ND filter, as the bulb dims as it ages, you have the flexibility of removing the ND filter. If you mount the projector at the furthest distance, you wouldn't have that option as the bulb ages.

I am lucky enough to have a completely light controlled environment and my previous screen was a 1.1 gain with my previous projector which was about 1500 lumens or less. The new PJ is 2,000 lumens and my DIY screen will be about 0.85 gain so I'm thinking that this setup will compliment each other nicely and I should be able to get away with just about any distance within that range. I plan to put it closer to the front so that I can adjust my brightness on the low end which should hopefully spell slightly longer lamp life but I doubt it will be anything substantial either way. Just brain storming out loud I guess.

I was watching a movie when suddenly the lamp on my Pro8200 turned off, I look at the PJ and saw this LED light configuration:

Power LED blue: solid
Lamp LED red: flash
Temp LED red: off

according to the manual this means " temperature is too high. the lamp will turn off. The fan motor is cooling the lamp. " the fan is working fine and the air it's moving it's fairly cold when I put my hand next to the PJ.

The thing is that it has been in that mode for the past 30 minutes so I'm beginning to wonder if this is normal and I just should wait it turns on again or if I shut unplugged it (it wonk let me turn it off, I've tried)

I have the PJ ceiling mounted so it has free space around it for air flow.
post #905 of 1081
ok I really couldn't wait any longer so I unplugged the PJ the I plugged it back(It was definitely cold) and it turned on and off normally.

if any one have any suggestion to avoid this in the future please let me know.

my lamp has only around 155 hours of use, this is the first time I was using it on normal in the past I've always used it in eco-mode.

I noticed your location - are you running this in an air conditioned room?
post #907 of 1081
good call on his location, it sounds hot. smile.gif
another thing, how is the power source, maybe get a battery backup, so if power goes through spikes or lightening you are protected.
This PJ needs plenty of space on the sides so it can allow the high air to move away from PJ.
Keep the environment clean, no smoking, etc, because it travels upward to ceiling, and you don't want to get the vents full of dust and smoke.
I'm in hot climate, so I turn my air conditioner on if it's around 80 degrees, just to help keep the PJ from overheating.
At least, the system works if it gave you the error message saying it's too hot.
If it happens again, maybe take it down from ceiling and try it on table, or bookcase to see if it also does it in different locations, just as trouble shooting method.

I want to put my 8200 into a soffet or an enclosed projector booth, how much space does this need for adequate cooling?
post #909 of 1081
Ok, still going through the RMA process after a week! Dealing with viewsonic is beyond BRUTAL!!!! I will have full details when I am finally through all of this, but I just wanted to give the people on here a heads up.
Also, the warranty page on viewsonics site is still down. Can someone please confirm this for me? Hopefully im wrong. Or at least some other literature on the warranty might be out there. All I know about it is some tidbits that I read on here, nothing actually set in stone.
Thanks.

I really would not recommend this. You could roast a marshmallow with this guy. The box would probably need some heavy air flow and cooling and would also need to be a good size. I think it says in the manual that it need something like 18" - 24".

I find this projector to be fairly quiet, even not on eco mode. is there another reason that you would want/need to enclose it?

no, we actually don't need air conditioning here.
I'm on one of the highest altitudes on my country and the temperature ranges from 18°C - 26°C (64°F - 78°F) most of the year. It gets colder this time of the year.

I have everything hooked up to a power strip/ surge protector.

the PJ has like 4 feet free space to the sides and like 10 feet to the front and back. the room is almost 10 feet tall.

I just enable the high altitude mode on it and will leave it that way in case that helps it.

It might be just an airflow issue with the room so I'll test it out more and open the 2 windows I have on the back of the room behind the PJ if necessary those don't really affect the amount of light in the screen.

If indeed you are at that high of a altitude, the high altitude fan mode should always be on. This is likely the cause of your overheating because the air is thinner and less able to cool.

now I'm wondering from what altitude is that mode recommended? I'm currently at about 4,317 feet over sea level.

I'll take a look to the manual see if it mentions it there.


Edited: the manual does not state at what altitude that mode should be turned on.

I believe 4,000 ft would be considered high altitude for this PJ's purpose.

Maybe I will put it under the soffet. I am trying to get the projector as high as possible so I don't have do any digital keystoning.
post #916 of 1081
Guys. Isn't there a way to force 24hz on this projector? I'm trying to get smoother 24fp playback. I can't find the settings.
post #917 of 1081
I'm not sure if you can 'trick' the projector to sync at 24p, but two panasonic blu ray players wouldn't allow 24p as an option to the projector, while the option was available on my plasma tv.
post #918 of 1081
Gotcha...after trying last night, I think I actually set the refresh rate on my HTPC to 59hz. I may have been a little confused. The HTPC will only do 24hz @ 1080i. So, I may have to keep troubleshooting from XBMC, it's actually not that bad really.
post #919 of 1081
Anybody build a hush box for this projector?

I live in a mild climate at sea level, in a cool basement. Mostly want it for protection of the projector (kids play down there). And because it makes a very high pitch noise even when turned off. Probably around 14,000hz.

Thanks.

Viewsonic has been a pleasure to deal with over my parents 8200. Their machine blew a bulb that destroyed the color wheel. They sent a refurbished model with a newer build date. That model had a stuck ON pixel in the middle. Support was kind in that they RMA'ed that 8200 and my parents are awaiting a delivery scheduled for early next week. Viewsonic has gone above with regards to my parents pj. There is no reason to use the warranty page on viewsonic other than calling the 877 number from their Customer service page here : http://www.viewsonic.com/us/customer-service/ . the 8200 beats my backups pj's-Benq5000 and Optoma HD80. My parents are running with the hd 80 now. Hope your situation works out.

Thanks for all the posting in this thread. I haven’t had a chance to read all the pages from the beginning but I would love to see more ideas on mounts. Specifically those of you who mounted it in the back of the room on a shelf or like the pictures I saw of it attached to the bottom of a shelf upside down. This is the route I want to go.

Im having some trouble finding the right way to set this up in the back of the room due to the throw angle. As of right now the best place is on flat on the floor with the front foot up about ½ inch. At some point I plan on having guests or kids around and I don’t want it sitting down there.

One other question: When I unboxed this it said make sure you have the following components, HDMI, VGA etc. Then it said optional Filter screen? But then I read somewhere it doesn’t have a filter?

To the poster 1 page back getting the screen from amazon. You know Elite has a rebate deal on the 8200 right now for a screen that size right?

Mine is not ceiling mounted, and I have used my pro8200 in lots of rooms. Generally I can go back 9-12 feet back and place on couch, or bookshelf, or stacking drawers, or table and get it to work. I have to tilt it a little or if I use on higher bookshelf, flip it upside down , and in menu reverse image. Maybe others can suggest bookshelf mount they are using. As long as I can go straight back from screen, I can get it to work, I will have to experiment, but I do find a place to put it, and it's not on the floor.

As for "free" elite screen, did you look at the shipping/handling charges on it, it's SUPER expensive , I can't remember but something like 80-90 dollars. I got 2 screens that work for me , and favi screen that I can get about 100 inch wide screen on it, and the epson dual 80 inch screen, both have tripods, that can both also be wall mounted and taken off tripod. I'm not saying to get those screens, just look for sale on any screen you researched and got good user reviews. Both got very good user reviews on amazon. I got the favi 80x80 (which opens up to about 100 widescreen, and only have to open it so it does give widescreen, not all the way) for 40 dollars from 3rd party vendor 11 months ago, and I picked up the epson dual 80 used from B&H that was in perfect shape (they have rating system on used stuff) for 70 dollars. These screens make the image POP and are tons better than white wall.

.

Really..... How ? Maybe I'm missing a setting or something but I have a room that is 18 ft long with around 8 ft ceilings. i can mount or place straight on. no angle needed. When I raise or flip it upside down I get the trapezoid. Are you using keystone correction?

When I raise to bookshelf level it's throwing half on the wall half on ceiling. If I flip it over its throwing half on wall half on floor. Like I said so far the only cool place is the floor.

Hello. I am new to the world of projectors. Just sold my plasma for a pro8200. Putting it into a 17.5 X 14ft room.(screen will on longer wall), 8 ft ceiling, 13ft viewing distance. First of all, thanks to all the people here for so much great info...i looked through as many threads as i could, and apologize if my questions have already been asked/answered:

1) The room will be lightly dimmed with a few lamps at all times (rarely watching with all lights off). My question: how much screen gain is good for me? I was thinking of an elite 106" with 1.1 gain. is this good? or should i go more grey?

2) Whats the deal with a 1 inch projected border around the image? Is it always gonna be there? Where should i put this border on my screen?

3) should i mount projector to ceiling first, or the screen?

4) My keystone was at 10 out of the box...is this where I should keep it?

5) For best image quality, should i zoom in or out (does zoom in mean make the image smaller?) In other words, does image look best when i make it biggest or smallest?


thank you in advance to everyone

jasoraso! Thank you for your helpful reply! Sorry I couldn't reply back sooner. But here goes...
Look what came on Friday!


Thanks for the confirmation of the offset and the range of where I can place the projector. Also good point about the amount of light that is actually hitting the screen and how the zoom/wide end of the lens decrease/increase the amount of light that gets to the screen.

Here's a picture of my room and the measurements that I wrote in on it, excuse the distortion, I used a fisheye lens to fit the whole room in:



The ceiling is 8', the possible mounting spot is about 14-15' from the screen (which will drop down in front of the wall mounted PRO-151FD, the screen I am looking for now is the AT Elite Motorized 100" screen (1.0 gain). As you can see I have a ceiling fan right int he middle of the room, and it comes down 17" (max, the light handle thing) So I have a couple of questions about this:

1) With mounting the projector as shown, and given the seating arear, will the PRO8200's fan be audible? I'm not worried about it on full lumen mode, watching sports during the day, more worried about ECO mode, watching movies at night during quiet scenes, the fact that it'll be mounted right above, or slightly in front of the seating area is what worries me.

2) Per my picture, will the 16-17" offset drop like the RED line in my photo or gradually down like the GREEN line in my photo?

3) The screen I am looking at is showing a "10 inch top black border" and with a 4" casing, leaves me at the picture being 14" from the ceiling. So it looks like I'll have to tilt the projector up slightly to make up for the offset, and use digital keystone. I've read that this is generally pretty bad, what is everyone's experience on keystone with the PRO8200?

The digital keystone is probably my biggest concern and I really want this projector to work. The worst case scenario, I would have to refund this projector in favor of a more expensive 3LCD projector for all the horizontal and vertical tilt shift lenses.

Mount the projector first, then the screen. This is one of the few drawbacks to most dlp projectors.


You are going to have a problem with the ceiling fan. The light path is the green line. Dropping the projector down so the center light/fan isn't in the light path is going to put the image pretty low on the wall. Keystone won't help in that case, since you have a physical obstacle in the way of the light path.

You can drop the pj 20 inches and still have plenty of space on your wall. My parents screen is a 92 in diagonal and the frame is filled perfectly without any key-stoning. They also have a ceiling fan in the left of the screen. there is almost 2 feet between the screen and floor. Just drop the pj under the fan and you will be alright ( the only part of the fan visible are the chains which drop a foot into the picture. My parents aren't tall.). As bse53 stated mount the projector first.
post #928 of 1081
Posted this in a different thread but did not get any response. Can someone check the below and let me know if you'd think it would work in my setting:

I have a dedicated theater room that doesn't get used that much, but I am looking to upgrade from my current projector which is an Infocus ScreenPlay 4805. I am considering the ViewSonic Pro8200 or perhaps an Optoma HD20 but no option is off the table. However, I want it to conform to my current setup which looks like the following:

1/ Based on my current ceiling mount, I expect a throw distance of around 14' (give or take a small amount depending on the length of the projector)
2/ Screen is 16X9/106" diagonal, 1.1 gain. The screen material (not the frame) currently starts at 10" down from the ceiling

Overall room has a ceiling height of 8' and length of 15.9'.

Projector calculations seem to indicate that the ViewSonic would require something like 18" from top of ceiling to screen which is obviously much lower than mine is now. I'd obviously have to tilt it if that were the case but I am wondering if that is a lot of projector tilt? The other issue is that the projector calculations move multiple variables when one is changed so I cannot input my variables as they are without others changing.

Thanks.

Hey everyone. I have a problem with my projector, hoping someone has a little knowledge of it. Was checking the menu during bluray playback and noticed under the info tab that the resolution is 480p. I have checked all settings on my player, power cycled all equip, bypassed my receiver, cycled through projector inputs, played several different bluray movies, still will not show 1080p. The picture does seem just a bit fuzzy but not all that bad really.

Any ideas what else to try?
Help please!
