M4600 IPS Screen Corner Tint

Well to be more specific, i return my first m4600 with one IPS replacement. Later i decide to buy another one that i have to express depot once, which they told me they replace the IPS and everything is fine but sure enough they are wrong. Then i have techs came to replace IPS screen twice, cable, motherboard and videocard for the second laptop. i then got a replacement for that one because i need a laptop for like two weeks so i agree for a replacement instead of return. they send me a replacement with the same problem which is the laptop i am using now and my third one. this last one got the IPS replace once. i grew tire of all this down time i have to gave so the next thing they offer me is the WLED.
LOL it sound crazy but true story. i have like tons of email,chat logs and case numbers for all this chaos.
The only person i know that had a good result is Beamerphoto but i never hear from him when i try to contact him about his screen information.

 

If anyone agree for a downgrade, make sure you get something to confirm that you will get a partial refund.
I been on the phone for one hour, department to department keep sending me around. Everyone say no refund and i am stunt.
Seem like i am getting my IPS screen back ASAP before thing get worse and waiting for a different resolve.

 

Hi all,
please find below RGB panel characteristic

So M4600 IPS Screen Corner Tint is not a issue.
I think HP's also have this phenomena,as HP use LG IPS panel too.

 

Well if that is the case, all the screen should have the same identical spot/placement of the tint color.
But for me, all the screen is different, my first one is worse. where color tint can be see from far away. then each replacement change a little bit, as in the placement of the tint spot moved and the intensity of the tint color reduce.
so by all mean i dont think there should be color tint. as far as i know only beamerphoto got a perfect screen but he hasnt answer to this thread yet. also he is the first one to report the problem so if his replacement got such tint he should be able to point it out. Even the dell engineer guy came to beamerphoto place had to agree that there shouldnt be color tint.

 

@Andy_BR: I am not convinced by this explanation. But I will search for such topics on the Internet. Also I will wait for M6600 users to make reviews of their IPS displays.
Besides, why green effect in left corner i waaaay bigger than pink/magenta in the right? I probably would accept this, if this tint was in as limited area as in pink corner.

 

@Andy_BR are you working for dell ? lol it seem like it to me because on another thread you ask for defective machines service tag number ? and all your posts only regarding dell precision issue that other member report here.
Some other question/concern i have:
1) how come the picture you gave only describe the 15.6 inch ?
2)if it only effect the 15.6 inch then why is that ? and how can manufacture let this happen.
3) if you can answer all the question above then where did you get all the information from ? bc that picture doesnt state any thing, at least nothing that any manufacture willing to back up

 

Hello,
wow, before I read this thread I was one of those "possible acquirers" of IPS display, because (and maybe all this story might be a reason) I found yet another type of "hard" discount on dell laptops that brought back the IPS upgrade to only 124€, compared to regular FHD WLED display. Maybe they are actually trying to sell out their not so good ips stock as fast as they can, hoping that a majority of the customers will not complain because either they don't mind about this tint, or they don't want to go through all endless support: they will change 2 or 3 times then quit and stay with a tinted ips.

With Optimus unusable and overall greater power consumption and difficult 10-bit support and cost, the IPS becomes less and less desirable. Especially for those beeing plugged all the time: why not keep WLED and buy an external LG IPS display at 200 or 300€? As it would be a standalone display, it will beat out any laptop built-in display, because it can be fatter, heavier and drag more power without restriction. I think I will go this way, after seeing all that happened to you all.

And BTW I think Beamerphoto has just quitted the post or the entire forum, because his problem is long-solved, maybe because he had good help from dell, and, as he seems to live in the US, home of Dell, maybe they actually shipped him some early release monitor (from prototypes or demonstration models or whatever), that was made in a different process, as early models do. Meanwhile, mainstream IPS monitors that are now manufactured all have this defect, and maybe the amount dell has already purchased from LG is enormous, and we will never know about that. In that case, they would have no choice, especially if their internal contract did not specify this defect as a sufficient reason for "mass and generic" refund from LG, for each faulty monitor returned by a customer. So all they have left are crappy solutions like replacing over and over again the same monitors, hoping everyone will tire out or downgrade to WLED - and not be refunded! This may be the result of a transition to mainstream production of a high-end technology, that has gone faulty. Before, for a built-in monitor like that, you had to put almost 4000€ in the laptop (like HP elitebook 8740w). Now with discounts you can have it at 2000€, and sometimes less. Maybe the "technology gone cheaper with time and larger production" phenomenon went too fast, and jammed a little bit.

You may try another thing: look for another laptop with reported good rgbled (as this is the primary source of the color gamut, not the IPS technology itself: IPS only refines the spectrum, the base of the spectrum is done by replacing the phosphor white light by proper RGB lights), wether IPS or not, and try having your laptop sent back and refunded completely, and buy the other one with the money. An idea of cheap RGBLED: the XPS 15 L502X. Ok, consumer grade and not professionnal, but with student discount for example you can have almost the fastest quad-core proc on the market, FHD RGBLED, and 4-year warranty and 2 batteries for like 1150€. Ok the display is glossy, not matte. But I am far from having looked to all the options, and I am sure other manufacturers have similar computers with different monitor models that may already be reported as not having that defect - and maybe not having any big defect at all...All of this is Dell/LG's fault after all.

By the way, this is the second time I hear of Dell using (on purpose?) components that have a slight generic defect: my old D830 died because of the G86M Gpu of the NVS 135M built-in graphic card, and apparently they all had a defect that shows up only with slight overheating and very long time of use. But when it shows up, your GPU dies very fast: actually, the defect is activated by temperature, but the activation temperature keeps getting lower, in a matter of days or weeks, until your GPU cannot start at all at room temperature. Mine "fried" this way after 3.5 years, while my (premium, business etc) warranty was 3 years. Great...If I could be invisible, and hear "private" conversations, this (your problem, and my problem) is precisely the type of problem I would like to know the exact - complete - cause and whereabouts. The real ones...

So, good luck to all of you. And thank you all for making customers aware of that problem...before they buy!

 

It is a pity that we scared people away from IPS RGB LED display. I would really like to hear from other users, for example those owning M6600 if they have such problem.

 

I think the RGBLED IPS is only made in 15 inch size, there is no variant in 17 inch...at least in france you cannot have the RGBLED IPS display unless you chose 15 inch...am I correct?
And as other people said, it is not because of 2 people having problems, it is about 2 people having a problem that would never be solved even through endless replacements. Allow me to have certain doubts about the fiability of such an expensive upgrade then!
And as I said also, I will have an IPS...as a standalone external monitor for use in my home with the M4600
And anyway I am too poor to buy it now, I have to wait 2 months, so maybe within 2 months this IPS bug will be corrected!
For such a big acquisition I prefer beeing 100% sure of what I buy, or at least as documented as possible...

 

As far as I remember the M6600 thread, Dell-ManoG announced lately that IPS display is also available for this laptop.
