The 2nd Official Infocus 4805 Thread. - Page 2

post #31 of 8120
I've never seen anyone recommend a 5000 over a 4805. SDE is supposed to be much more noticeable on the 5000, since the spacing between pixels is much greater.

Move the candle

I had a candle in front of mine and had this effect going on, from the heat being left off or something (im not engineer)

1) The unit appears to be like-new. No visible signs of usage. Menu shows 0 hours on the lamp.
2) Firmware revision is 1.1.3
3) The laptop screen resolution is 800x600, connected via the enclosed VGA-to-M1 cable.

I just projected the image to a wall for the first checkout, but even so I was wowed by the clarity and vividness of the picture. However I did notice one problem: The right 1/3 of the screen shows a slight image distortion. The best I can describe it is as rising smoke or rolling clouds, moving from the bottom to the top of the screen. It is faint but noticeable to me, my wife didn't see it at all until I spend a couple of minutes pointing it out to her. Am I experiencing this (from the FAQ):



If this is something that can be fixed with an upcoming firmware upgrade, I'll hang on the the 4805, otherwise I'll try to send it back for a replacement.

Thanks!

I'm glad you decided to make a new thread. The old one was just so overwhelming to usnewbies. I think I have mine ordered and on the way, but it's still in "processing" so I'm crossing my fingers. I really want this projector, and I really need it cheap.

5000 sucks, get 4805. See my post on the 5000 thread.

I have my 4805 on a table and after it heats up you can see the waves on the screen....so I took a small battery powered fan that I had and put in on the other side of the 4805 and blew the hot air away from the lense...problem solved. My battery died the other day, and I have not charged it, but I don't really find the heat waves that distracting.

I don't get it - why did we start a new thread? How was the other one confusing? Now, we have a short thread with little info. How is it less confusing when you just post and look for responses anyway? Does the new thread make it OK to post questions that were answered last week, ispe dixit?
post #36 of 8120
The 4805 vs the 5000 is more about DLP vs. LCD.

DLP gives more contrast, better blacks, less SDE than older tech LCD like the 5000.

I haven't seen the 5000 myself, but from what I've read you'll probably be happier with the 4805.

I agree. There was some good information available in the original thread. It would be nice if people posted relevant questions or information too instead of cluttering good threads with worthless posts to increase their post count.

BTW from everything I have read on the 4805 vs 5000 on this forum, everyone recommends the 4805. It seems to perform better with movies and video content. I am buying one tomorrow.

Huh!? Since when does the 5000 have 1080 native resolution??!!

I don't know why people keep asking this same identical question. The 4805 is head and shoulders above the 5000 in overall PQ.

I won't repeat all the reasons again here. Do some research!! Read a few of the many threads on this comparison instead of blindly asking over and over. Sheesh.
post #39 of 8120
Cavu, I agree, but calm down. We don't want ya having a heart attack...unless, of course, you're putting me in your will to get all your AV stuff.
I got my refurb 4805 today and bulb was new, unit looked good out of box, and all manuals, cables, etc. was all there. No factory box, who cares? No problems so far, but I'm just in initial stages of playing around with it. I'll post again in a few days after this has seen some heavy usage and been "unprofessionally optimized" by my own humble hands and knowledge.
post #40 of 8120
how do you guys just getting your refurbs know that the bulb is new? Thanks.

I think they are just looking the hours from the about menu. But that could be reset by anybody. Unless there is a secondary counter that is not accessible from the user end it's tough to know the accurate hours on bulbs. I hope all the guys that bought this PJ from S refurb will report their experience.
post #42 of 8120
could someone suggest a cheap wall mount? it's probably given, but i want the pj as close to the back wall as possible
post #43 of 8120
I got in on one of the 4805s recently...I had to get rid of a few dust blobs but otherwise its been great except for cable TV.
I have a Comcast HDTV/DVR box and am feeding the 4805 via component video.

I am getting some noise with it.


DVDs via component look great , ive only fed it interlaced. I swapped out cables first and that did nothing, my LCD TV looks great off the same set-up but the 4805 gives me some noise in spots...its pretty distracting.

...ive tried everything...help me out here.
post #44 of 8120
Just got my refurb today, and am quite pleased with the unit and the pic quality, but I have a couple of dark almost black specs that show up on my screen while watching a dvd. They appear to be little specs of dust. I cleaned the lens exterior, but that didn't seem to help. I've read about dust blobs but these look different than the pictures I've seen. The dust specs appear to be in focus, as I can see the strands of dust quite clearly. Any ideas?
post #45 of 8120
I got my refurb today as well. I am more than satisfied with it. It seems to be in alright condition. Mine has a scratch (i have no idea - it's on the side of it opposite of the power switch) I do have a couple of dust blobs that are outside of the viewing area (odd). I thought that it was lightspill, but has the characteristics of dust blobs methinks. I'm still loving this thing...


As for the mount - I went to lowes tonight and picked up some galvonized (*sp) tubing and a piece of lucite. I have a couple more items to pick up - but I have almost all of the items I need to build a DIY mount, and so far I only have a few bucks invested.

Would anyone happen to have a printable mounting schematic of the 4805 - to make drilling the lucite easier?
post #46 of 8120
Umm Mr Moderator sir.... before you delete it - can you please move that awsome post with pictorals on cleaning the dust blobs out - over to this thread? I think the poster started a thread of it's own with that post.

For extra credit - can you do the same for the color wheel cleaning guide?

post #47 of 8120
EDIT:'Adamesq', please take note that you/I/we cannot offer an objective view on why or why not the thread should have been restarted. The new people think it's a great idea, the older people are boggled by it and possibly also frustrated.

*flashback*I remember starting into the old thread at around 500posts or so. It was daunting then, let alone now!*/flashback* Using search is the appropriate means to finding most answers, but lately I've found that I need a search within my search. Finding Bob's numbers for example, the 50ish/28ish stuff, it was damn near impossible. There are numerous references, but I'll be damned if any of them were useful to me. It took me over a half hour of looking through the search results to find the info I wanted. It would have taken so much less effort (albeit distributed effort) to just ask.

The problem with the old thread as I see it is that there was far too much 'noise'. It was useful and also entertaining, but it was a bugger to find facts in. Enter the FAQ. Wonderful piece of work. Glad it's at the top of this thread too! It doesn't have all of the nitty-gritties though, which can be required if you are trying to apply the facts to a specific and non-standard application. Maybe we can write a 4805 ultra-FAQ, with each section including links to the appropriate source material in the old thread(s) for more in-depth reading.

That being said, most questions can be solved with an < 3min thread search. Don't be lazy new people!

Question:
How many 4805 users are using light controlled rooms WITH accoustical and reflective light treatments?

I am working on treating my theater, and it's proving difficult since it is a rented house and major modifications aren't within the scope of my lease.

So far I'm trying to source some rigid fibreglass in my vicinity, and find some good black fabric to tack to the walls and ceiling around the screen.

post #48 of 8120
Quick first impression on my new (refurb) 4805: I love it! I think, though it's too soon to say, that it may have cured me of RBE - which was the only real problem I had with the X1. Yeehah!

Lamp looked new prior to startup (but I can't really tell), lamp hours were at 0.
No problems/noises.

Throw is shorter (or is it longer) than the X1 (by a greater margin than I expected), I'll have to move it closer to the screen.

Off to watch my first movie - The Muppet Christmas Carol, just released yesterday.

If you actually get that order I'm gonna be pissed... they cancelled mine. Wound up with one from Cr********d. $300 more, but new.

Yes sucks to be me.

You read my mind....
post #52 of 8120
The way you can tell the bulb is new is because the bulb housing is not scorched. Sure they could reset the hour counter but they can't "unscorch" the bulb housing. The bulbs are new; at least mine was.

I'd like to comment on the discussion about the x1 vs 4805. People who think that the 4805 is "not a step up" from the x1 have obviously not seen the the 4805 pixel mapped over dvi. The picture is unfreakin' belieavable. I've had my 4805 for 3 days and I just got my dvi cable tonight. The x1 pq sucked in comparison to the 4805 pixel mapped. Let me say that again. THE X1 PQ SUCKED IN COMPARISON. I too was unsure as to how much better this unit would be then my trusty x1; night and day people. Don't get me wrong the x1 is a great PJ but the 4805, wow.

BTW i'm using theatertek and the nvidia pure video drivers. One word: AWESOME!!!

OK I need to stop drunk callin.... no seriously I'll have the more or less same setup. Ordered my Montego DDT sound card for gaming yesterday too. Wish I could take Friday off from work.
post #54 of 8120
All I can say is WOW. I just got my SP4805, I upgraded my 4800. I didn't think there would be that big of a difference but there is. The colors pop so much better on the 4805 and the blacks are amazing. Just thought I would share my thoughts. I now know why the old thread got so big and I'm sure this one will get even bigger. Best money I ever spent, or should I say made. I sold my 4800 for $50 more then I spent on the 4805 gotta love eBay around the holidays.

Just curious, did you ever do a color wheel cleaning on the x1?
post #57 of 8120
What's the best connection(s) to use with a Comcast DVR 6412 box to a receiver to the 4805? I DON'T mean just for the HD channels, but for ALL the channels. What I'd like to use, if possible, is one connection only, straight from the back of my receiver to the PJ, and have the PJ treat all the sources (DVD/Cable/Gaming/Etc.) as one, with the receiver making all the necessary decisions on what source signal to send. I had my old PJ set up this way with s-vid cable only, and while easy for configuration, it's lousy for quality. I know, I know, it wasn't the best way to go, but I needed a quick setup and then got lazy. This time, I want to do it all the right way the first time, even if it takes more effort and/or time. Thanks for any suggestions.

Ja Phule,

I cleaned the color wheel three times over the 1300 hours I owned the x1; every 400 hours which was probably overkill. I also had flashed it to the 4800 firmware and calibrated it with DVE.

There is just no comparison. DVI is what makes the differnce, no digital to analog conversion and true 1:1. The picture is just so damn clear. I thought that TFE superbit looked good on my x1, it blew me away on the 4805. Can you say reference material!

I need to calibrate the 4805 but can't pull myself away from just watching it.

I've got a question for you Ja Phule. I've read your FAQ and I see that it says we should change the color offsets if your running dvi. But then it says that the 4805 is set for pc color offsets. Since i'm running a htpc I should not have to change the color offsets to the bob williams ones right?

Thanks
post #59 of 8120
I got my refurb on monday and love it.. noticed the firmware on mine is at 1.13 and now current is 1.2.1 up to you if you upgrade or not, I plan to, but from what i can tell, it doesn't add a whole lot. BUT i like to be current. On that note could someone give me the full name of the executable for the 1.2.1 firmware update, capitalization and all if ya know it?

I knew I was going to get my refurb on Black Friday, so i bought a Oppo Digital dvd player, ok a little over kill, but I'm loveing the picture so far.

Also I purchased an dvi to M1 adapter for ~12 bux shipped third party not from infocus, and it works well as far as i can tell, everything was ready to go when the pj showed up monday.. well cept for the sreen, i went the parkland route, and Like it quite a bit (as some point i might try the magic mud and paint it) but for now my 4x7 or so foot screen is awesome.

Also managed to find a cheap OTA hd receiver (well sorta) less than 50 bux shipped (17 or so for shipping) e bay and all..

But a heads up if your looking for one, I got an old Voom box, aparently if they were activated prior to them going out of service, you can use them for OTA.. which is fine for me, since Im all about the cheap.

Oh yeah.. just curious.. are there any hidden service menus on the sp4805, if so are there any useful settings in there?

It depends what levels your pc is actually sending from its DVI port. I believe you want to use the studio dvi levels if you are viewing movies on your pc using VMR9, since VMR9 outputs video at studio dvi levels. If you're using Overlay, stick with pc dvi.
