message: I tried to print this article, and got page 3, 4, 5 as blank pages out of total 7 pages.
I tried Adobe Acrobat printer too, and got same error.
Then, I switched to "Printable Version", and this problem went away.
I don't know how to fix this by myself, only thing I can do is to report this.  —Preceding unsigned comment added by Hoonham (talk • contribs) 04:28, 16 December 2009 (UTC)

thread_title: This article has printing problem

message: I tried to fix some errors in the DMD section.  For example the article said that each mirror represented a single pixel.  That is generally not true in modern DLPs due to Wobulation.  I think what I wrote better reflects the current state of DLP TVs, but it still implies that DMDs come in 1920x1080.  My understanding is that the vast majority of DLPs sold as 1080p sets, do not have a 1920x1080 DMD in them, but one half that size.  I could not find the website where I read this and was working from memory, so I did not want to get into too much detail about it.  Maybe someone else could make it a bit clearer which sizes modern DMDs come in, and how they correspond to the HD resolutions.128.117.194.163 21:30, 24 July 2007 (UTC)

message: The Cons section essentially states that "LED is the end of all troubles." Does someone have a citation for this? Supposedly according to a different part of the article LED DLP projectors are not even released yet. Iamthebob 02:17, 28 July 2006 (UTC)
replies: text: LED DLPs are released.  I just got my Samsung HL-S5679W yesterday.  It is the end of all of those troubled listed in the CON section, but my particular set introduced some new problems in Color banding which probably has more to do with the image processing than the fact that the light source is LEDs.

replies: text:  The article makes a zillion references to LED driven DLPs eliminating rainbow effect, but is this actually true? All the LEDs do are replace the color wheel with a sequence of flashing lights. The image is still an additive process with different colors being projected at different times. I'm sure that the LEDS can flash faster than a color wheel, so as to even further minimize the rainbow effect except for those with superhuman vision, but the way the article is worded implies that the rainbow effect is just not even possible with LED DLPs. I don't believe that to be true. 216.85.117.123 00:22, 12 September 2006 (UTC)

text:  I added that material. Your understanding is basically correct -- you'd need superhuman vision to see a rainbow effect with a LED DLP. Feel free to edit if you feel I didn't get that across clearly. Jerry Kindall 20:50, 25 October 2006 (UTC)

thread_title:  Are there actually cons? 

message: All the contributions of User:65.118.181.114  are about a not-yet-out NuVision DLP projector with LEDs, and therefore probably classifiable as commerical spam.  That's why I marked some of them with citation needed (fact) tags.  They should probably just be removed unless somehas has a published source. Dicklyon 21:42, 12 September 2006 (UTC)

replies: text: wasn't me in the 1st place, but looks like there are some. 
LED section looks more like a marketing for the Samsung and that other led company than actually discussing the principle and merits of LED vs other light sources.  — Preceding unsigned comment added by 98.247.34.84 (talk) 20:39, 14 March 2016 (UTC)

message: In this section of the pro/con area, it says plasma displays use fluid as the projection medium...
"Unlike their LCD and plasma counterparts, DLP screens do not rely on fluids as their projection medium and are therefore not limited in size by their inherent mirror mechanisms, making them ideal for increasingly larger high-definition theater and venue screens."
That doesn't make a bit of sense.  It seems like two different points are being made at once.  Might be clearer said this way??:
"DLP displays are limited in size only by the power of the projection lamp and the mechanism's ability to dissipate the heat from a higher powered lamp.  This is in contrast to LCD projectors, which create an image by using liquid crystals to block unwanted light.  They are size limited by their ability to adequately block that light, and their ability to function with the higher levels of heat a higher powered lamp would generate.  LCD and plasma direct view panels are size limited by manufacturing constraints and the physical constraints of maintaining the integrity of the panel."
I mean, plasma displays aren't actually fluid based as the original paragraph claims.  They are just a grid of (in essence) tiny fluorescent tubes.  Instead of using a white phosphor as in fluorescent lighting, they use colored phosphors.67.167.249.170 (talk) 22:02, 19 December 2009 (UTC)

message: Guys, i'm sorry, but I think the pros/cons section is definitely original research. At very least with the things that can be said sourced and objectively, change the title of the sections to be more neutral. JoeSmack Talk 17:51, 20 December 2009 (UTC)
thread_title:  Pro/Con = Original research 

message: The article reads "There is a maximum rotational speed limit for the wheel, typically 10,000 to 15,000 RPM." and goes on to describe how this is related to framerate. Is repeating the colour pattern on the colour wheel not an obvious solution to this problem? It also contradicts an earlier passage that says up to 10x rotation speed is available. This passage seems out of date or just plain incorrect, but I'm not an expert and don't have a primary source to reference.

thread_title:  Max RPM? 

message: TI's page on DLP trademarks says:
:The DLP® trademark is not an acronym for the words 'digital light processing' and should never be followed by '(digital light processing)'.
On the other hand, a paper by Hornbeck puts a TM after Digital Light Processing.
It looks to me like the opening paragraph should draw some appropriate distinction - perhaps, for instance, it should refer to digital light processing as a technology and DLP® as a TI trademark for its line of products implementing that technology.  However I don't know enough of the whole picture to write it myself.

replies: text: It looks simpler to me to simply ignore the DLP® trademark. In fact, it should never be followed by '(digital light processing)', as TI puts it.  This clarifies that we are not talking about the DLP® trademark in this page. --Pot (talk) 22:40, 14 November 2010 (UTC)
replies: text: But if we are not talking about the DLP trademark, how do we know that we are talking about the right thing?  For some reason, I always thought it was Digital Light Processor, but it seems that neither term is used in the TI web page. Gah4 (talk) 03:36, 10 June 2019 (UTC)

message: The use of a replaceable light source means a potentially longer life than CRTs and plasma displays (this may also be a con as listed below).
This is not true compared to CRT projectors, because the tubes are exchangeable and have a higher average lifespan then the bulbs used in DLPs: . --80.109.39.94 (talk) 01:43, 4 March 2011 (UTC)

message: The entire opening section is mainly of an X is Y form, rather than Y <verb> X form. It comes across as stilted and verbose. Compare:
:The single-chip version of DLP and 3LCD are the two main technologies used in modern colour digital projectors, with the two technologies being used in over 95% of the projectors sold in 2008.
Rewritten without is:

thread_title:  The color wheel "rainbow effect" 

message: A beamer equipped with a DLP device worked well when new. Over time, individual pixels were not working anymore (turned constantly bright). The number of defective pixels grew to the extent that picture quality was not any more acceptable. The beamer had to be replaced. The new beamer is an EPSON model using three LCD arrays for picture generation instead.
Assumption and questions:
As each DLP micro-mirror is supported by a thin, fragile metal suspension band / hinge, it is easy to understand that metal fatigue can set-in by bending the mirror frequently. This is particularly true, because gray-scale pixel information is displayed by pulse width modulating the mirror deflection, with the mirrors switching thousands of times per second.
* Is this assumption correct? 
* Do other users have similar experiences?
* Should this type of aging be mentioned under Cons?

It desperately needs to be rewritten to 
#1 remove all advertising/marketing/spammy language 
(everything that sounds like it came from a mftr "product line pamphlet")
#2 reset all verb tenses to give the article a neutral tone
#3 remove competitive language and replace with comparative language referring to other display technologies  — Preceding unsigned comment added by 24.6.93.78 (talk) 03:19, 30 October 2014 (UTC)
