I recently noticed the dreaded blue discoloration on my Sanyo Z3. I have had it about 3.5 years with 3400hrs on the unit (1400 on my 2nd bulb). It is out of warranty, so I am looking at purchasing something new.


I have been comparing the Optoma hd65 and the Sanyo PLV-z60. The Sanyo would be an easier setup, in that I believe my current ceiling mount would work and it does have lens shift.


I have been reading about organic and inorganic LCDs. Are the new inorganic panels less prone to wearing out as were the ones in the Z3? Are LCDs in general suppose to last longer nowadays or is DLP the way to go? I am hoping to find a projector that would last a lot longer than 3 years.

DLP everytime. Having owned 3 LCDs and all exibit discoloration issues within 500hrs, I'm done with them.

Hey,

I'd look for used 1080p units off Videogon (or here on AVS) before I bought a new 720 anything...people are going to flame me for saying 1080p over 720p (b/c there ARE a lot of GREAT 720p) but in 2009, you can pick up a used 1080p for not much over the 4 figure mark (you can even find a used RS1 for what 720s were going for a few years ago)...just my opinion, but 1080p was made for big screen home theater.

If you buy off videogon (I never buy used for warranty and bulb life factors),make sure the bulb has low hours or you could end up paying for a new bulb as well. If the HD65 works in your room get that. You only have to set it up once.

I don't think I would buy a used projector unless I fully expected to purchase a new lamp soon. I would seriously consider a factory refurbished one however. I've bought many electronic items refurbished and NEVER had a problem. I might worry more about a refurbished projetor than an ipod, but I'd still probably buy one anyways.

If you suffer from RBE don't get the HD65. It's quite bad in that respect, much worse than a true 4x speed DLP.

 

[ditch-digger]

dlp for me, i have seen both types...and prefer dlp for the best image.






imax is dlp........

My Sanyo Z3 is still flawless at 900 hours, but I've been looking to upgrade to something better anyway. It's just a question of getting a DLP with lens shift ...


Bought the Z3 in 2005 because DLP had no affordable shifting capabilities. It's going to be 2010 soon and DLP still hasn't adressed the issue in the under 5K market. That's frustrating as a potential customer.

 

[K-Spaz]

I'm surprised that lens shift would be so important to some folks. I have a less than ideal situation also. But I forced the DLP to work for me and fact is, after doing so I would be inclined to tell people to go through all the setup even if they had Lens shift. The less you do to the image the better.


I guess it all comes down to the old comparison of a Prime lens on your SLR vs a Zoom. I'll take the prime w/1.4 or 1.8 fstop and fight with the framing every time.

 

[TrickMcKaha]

You ask a good question re the longevity of LCD now that inorganic panels are available (if you shop carefully enough.) From what I have been reading, people don't know for sure, yet, because the inorganic panels have not been out long enough to be certain. Most people think they will last twice as long as the organic ones, and any other parts in them that do deteriorate from heat etc. should be fairly cheaply replaceable.

I don't understand the need for lens shift. A great DLP like my Sharp DT-500 still looks better than any LCD remotely close to its price range even if I use the keystone. I notice no negative effects using it with this pj. I don't use it, but I have tested it. So, I see no point in lens shift.

 

[BlackRiderX]

I would need a lot of keystone correction to switch to DLP, and I could do without the loss of resolution and PQ. Better to just stick to LCD in this price class in my situation.

 

[K-Spaz]

BlackRiderX

I don't know what loss of PQ you're talking about. And also don't know what loss of resolution. ?? Hmmm?


They're all pretty much the same res, either 720 or 1080, unless it's a multimedia pj.


I can understand if you're handcuffed by the lack of lens shift.

Digital keystone correction adjusts the image proportions by shrinking the image at the edge furthest away from the screen before it is generated by the projectors image panel(s). Hence, the image will lose resolution towards this edge. Digital keystone correction may also introduce artifacts, such as jagged edges.

This is what I am talking about. I've simulated the offset of a dlp unit with my current lcd projector and it's lens shift capability. Tilted the machine upward and applied keystone correction as needed. I had to zoom the entire image even more to fit the screen, resulting in resolution loss on the sides of the picture.

 

[jarrod1937]

Any form of keystone correction is exaggerated imo. I've been through many projectors, and i avoid any keystone correction available... yet the results are near perfect every time.

You may not know this, but lens shift also degrades the image. Its akin to the optical zoom on projectors with lesser optics, resulting in color aberrations and uniformity issues. And as with zoom, becomes less of an issue the better the optics get.

Truthfully if you got a dlp in your room, you will see that you will have to work harder to place it, but its not impossible for almost all rooms out there to get a relatively low keystone setup.

 

[BlackRiderX]

I personally can't really see color aberrations and uniformity issues, I can see resolution loss with keystone.

 

[BowerR64]

IMO the DLP has a better image but i myself prefer LCD because of the rainbow effect. I dont care for that at all.


Once i started to see it thats all i think about now when watching a DLP projector. The LCD i have is fine and i can actualy just sit back and watch the movie.


Some people cant see it so its not a problem.


Having 2 projectors and using them both at different times i really notice it alot more.

DLP TVs generally offer the best bang for the buck in terms of screen size—you can't get a 60-inch LCD or plasma for anything close to the price of a similarly sized, lamp-illuminated DLP

And there's a reason for that...RPTV's images look cheap compared to any plasma or LCD and off-angle viewing is terrible. They were the first technology to provide a big screen and soon will be no longer made as LCD/Plasmas drop in price.


I've owned both DLP and LCDs PJs. Had panel mis-alignment on all LCD PJs after about 200 hrs - more noticable as they got older.


The DLP always had a clear bright picture, but looked "digital", not so film like...but this was on a 480P version.


Lens shift is a key ease-of-placement feature and goes a long ways towards easily obtaining a clean picture free of geometric distortion and "key stone" type of processing. -- Think about it, if you could move the lens up or down 2 picture heights & L/R by 1/2 picture width - that makes it easy to place the PJ on a rear shelf, to the side of the couch...


DLPs typically don't have lens shift and have a long throw, which combined makes their placement difficult.


Recently Optoma introduced the HD82 which seems to be the best all round solution IMHO- DLP, Lens shift, Vertical Stretch, quiet, DarkChip 3, only prob is that its $5K.

 

[buddahead]

IMHO'LCD has blown past DLP for image quality.In fact I see DLP going away soon.They only make up 5% of fp sales now.Why invest in old technology.And for MTyson question why someone would need lens shift'wake up dude.
