Diff between 15.6HDF TLF LCD and WLED

This is my first post in this forum. While going through some threads, i saw on most of the 15.6' XPS systems, 15.6HDF TLF LCD screen was mentioned. I believe that 15.6HDF TLF LCD is different that WLED screen. There was no option to choose LCD screen while configuring the laotop online. I ordered my XPS with WLED and when i was tracking my order, came to know that they have shipped with 15.6HDF TLF LCD screen.
Does anybody know the difference between these two OR are they same?
When called Dell SUpport, they straight away said to return the system. What the heck..

 

The difference is in maximum screen resolution. There is also significant difference in color appearance as the WLED isn't capable of the same amount of gamut. Maybe that should be degree of gamut. Back when I got my SXPS16 I ended up getting two identical systems with the exception being one had the WLED screen and one had (still has) the RGBLED screen and the difference in them was night and day. The WLED one was very nice, the RGBLED blew me away. I just got (like 30 minutes ago) the new XPS15 with the B+RG LED screen and it is exactly the same quality and mind blowingness as the RGBLED on my SXPS16.

 

Hi Paresh,

Today I completed and order for an XPS as well. I'm having the same issue as you, when I was selecting and completing the checkout for the laptop, it showed "15.6" HD (720p) WLED Display"

Afeter I completed the checkout, in the email they send to confirm the order now says: "15.6HDF TLF LCD"

I'm really worried about receiving a screen with lower quality I paid for. What happened with you? Did you get it solved???????

Thanks!

 

Juan you paid for the low quality screen if at checkout it said 720p WLED.
They gave you a much higher quality screen.

OMG, I hope you're right. For some reason I thought that a WLED screen was superior to a LCD...... I really know very little about screens and laptops in general.

Thanks for help guys.

 

You're confusing different types of technology. LCD is a Liquid Crystal Display. Every laptop has a LCD screen. LCD panels are composed of millions little 'liquid crystal' pixels that either block light or let it through depending on the voltage applied to them in order to create the image the computer sends it.

WLED (White Light Emitting Diode) is a type of backlight, or the source of the light that passes through the LCD. Other types of backlights used in LCD displays are CCFL (mini florescent lamps) or RGBLED, which uses separate Red, Green, and Blue LEDs to create white light.

All current-gen XPS laptops use WLED backlights. Dell calls the premium display on the XPS 15 B+RGLED, though that is just another term for 'WLED' (as all WLEDs are actually blue LEDs that are covered in a yellow (red+green) coating to create white light).

The main difference between the two LCD panel options on the XPS 15 is the resolution. The cheap standard panel is a 1366x768 (also known as 768p or HD) panel, and the premium panel is 1920x1080 (1080p or FHD 'Full HD'). The 1080p panel is higher quality and has much better specs besides just the resolution, but that is outside the scope of the terminology used.

Note that HDF is not FHD (though I've never heard of HDF), so likely you will get the regular 768p WLED panel that you paid for.

 

Exactly what I was going to say.

 

Hi Juan,

Sorry to disappoint you, but you are getting the screen you had selected and not a 1080p one. Here's how the XPS 15 screens appear on the website and the order confirmation e-mail.

15.6" F(ull) H(igh) D(efinition) (1080p) B+RG = 15.6FHD TLF LCD L501X
15.6" HD (720p) WLED = 15.6HDF TLF LCD L501X

 

Was about to mention that...

Technically, the screen you ordered (the 1388x768) is considered a high-def display too since its above 720p. Whether it s full high definition (1080p) is another thing altogether.

 

If the B+RGLED is the same as WLED then why does it look just like an RGBLED display as far as color gamit goes?

 

It's just a much higher quality WLED. A true RGBLED would have well over 100% color gamut. Honestly though, I think the "B+RGLED" brand WLED is better than a true RGBLED, as it uses less power, is less complicated, and the colors are more accurate (having a color gamut over 100% is not really a good thing, as it reduces color accuracy).

 

Hi, what is the detail that appears on your lap top when you Go into Device Manager Click the + next to Monitors right click Generic PnP Monitor click Properties go to Details in the scroll menu click Hardware it should show : MONITOR\XXXXX


In my order appears: 1 320-1673 15.6FHD TLF LCD L501X

I just want to be sure that i get the RGB Screen, not the cheap one.


Thanks in advance.

 

everyone getting the HDF are getting the "cheap" one of 720p
everyone getting the FHD are getting the "good" one of 1080p "B+RGLED"

hope that clears things up... there are only those 2 types of displays for the XPS 15...

 

I don't know why people are saying that the choice on dell website for xps is between hdf(720) and fhd (1080), here is a copy from the options - both look to be 720 - so people were trying to chose recommended by dell - that's why they think they are getting a cheap version when the other option appeared. And they assumed that the recommended by dell - prices vary is a good one - but both are WLED. Looks like the design studio - is just for the back cover - and display stays the same - i don't see the choice of higher quality display. So whatever I guess appears at check out - is the same cheap thing...

So there is not much choice? Or maybe the choice was there - but not now?

This is the choice posted by dell:

a)Silver Anodized Aluminum 15.6" HD (720p) WLED Display with 2.0 MP webcam [Included in Price]

b) Design Studio 15.6” HD (720p) WLED Display with Facial Recognition and 2.0 MP webcam Personalize Prices Vary - Dell Recommended

 

aab, the FHD (1080p) choice was available a few weeks ago, but Dell sold out of them. I think the estimate is that they will have them again towards the end of January.

 

I wanted the 1080 display so bad that I thought I ordered one from Dell today - a refurb that I got a same as new warranty on. The description said: 15.6 inch Full High Definition + True Life Display. My confirmation of receipt of order has the same description. Then when I get the Order Details, it says differently. It's described as Liquid Crystal Display 15.6 HDF,True Life, LG Philips, LCD Nimoy. This is very upsetting because I wouldn't have ordered this laptop if I thought it was 720 display. Nowhere in the description does it tell the resolution. The 14 inch display is described as High Definition WLED, and I presume that is definitely 720.
So I "chatted" with an agent before they could send this order because I was ready to cancel. He was confused also and checked with tech support who says I am supposed to be receiving the 1080 resolution. I assume it would be WLED even if 1080. I have 21 days to return the laptop in when I get it and if it is not 1080, it goes back.
I think the screen resolution description on the Dell site is clear as mud. The only number resolution given on the XPS is the 17 which has 900. I debated between Dell and Asus and have a feeling I should have bought the Asus with the known 1080 resolution. At least the resolution was stated in the description.

 

Midwestuser: I'm in the same boat as you. Did the same exact thing. (cancelled a much cheaper inspiron 17r, with a coupon, in order to do this). I'm hoping it works out.

 

It's Backkkkkkk On The Website For New Orders Too!

 

It's not back yet here in Canada. Hopefully, it comes back in a few days.

 

1 P5XP1 Module, Liquid Crystal Display, 15.6HDF, True Life, Lg Philips Lcd, NIMOY
1 1K0R2 Liquid Crystal Display, 15.6HDF, Light Emitting Diode, True Life, V3, Lg Philips Lcd

that's the 720P screen right?

 

"1 P5XP1 Module, Liquid Crystal Display, 15.6HDF, True Life, Lg Philips Lcd, NIMOY
1 1K0R2 Liquid Crystal Display, 15.6HDF, Light Emitting Diode, True Life, V3, Lg Philips Lcd"

that's the 720P screen right?
-------------------------------
That is the same parts list as my computer and I have the 1080 screen.

 

Darn! I ordered a day too soon. I can't believe it but according to Fedex my laptop is supposed to be here tomorrow. Just ordered it yesterday. I'm not going to hold my breath waiting. Fedex generally runs a few days slower than stated.

I have a feeling it will be going back Monday because I just know this is not the right display. The price I paid was nearly what I would have paid for a new one because some of the things configured on the laptop wouldn't have been my choice. If the display isn't right, it's going back.

 

I couldn't find it on the website tonight. I probably ordered a few days too soon. I would rather have new but if mine is the 1080 screen and everything works OK, I won't complain. I'm a little afraid of refurb but bought the complete care warranty.

 

I got my laptop today and it was not the 1080 display. After talking with 8 different Dell representatives I finally got an RMA and I printed out a UPS label to send back. Also ordered another laptop. They are specified now as to HD720 or FHD1080 on the website. My order had been for FHD.
They offered $100 of to keep the laptop, but I put a SD card in it to look at some of my pictures and was not impressed.

 

okay yeah, because I can confirm mine IS the 1080 screen.

I had thought I got lucky and dell screwed up.. I got the fast-track option 3
(i7-740/435m/640gb/6gb) and thought it only had the 720p screen.

I guess I was wrong, in the best way.

also, your service tag show up as an inspiron duo? because mine does...

 

I just ordered the XPS 15" with the 720P LCD... Can anyone let me know how the Quality of the lower 720 LCD is? I remember having a 14" Inspiron and when I recieved the laptop I returned it because the LCD was really grainy.

I wasn't interested in the 1080P on the 15" because I hate the small resolution and prefer the 720P, however I'm concerned about the quality. Thanks.

 

I just received the xps 15 today with the 720p lcd. I sent it back. I didn't notice the graininess or the pixelation that I had read about. The screen was really bright but with an extremely bluish cast. I put a SD card in from my camera and it really showed it on the pictures too. I'm sure that if I had played around some to adjust the monitor that I could have made it better but I ordered 1080p and expected to receive that.
In the stores I have seen what appears to be much better displays on much cheaper laptops. I thought that the background was even bluish compared to a true white. Overall it was a better display than my 3 year old Gateway which also had a bluish cast to it.

 

Yep. Same fast track option, same issue with the service tag showing Inspiron duo. I thought I was crazy with all the posts saying "HDF" is 720 (which appears to be the case) and getting the 1080. I guess we got lucky (I was expecting 720 as well), and with the 1080, the deal is even better. I just hope this doesn't lead to any issues if the screen malfunctions, etc. (What would they replace it with???)

 

well when i ordered, the choices were 720p wled or 1080p wled.. THEN THE NEXT DAY, it changed to:

720p wled

or

1080p B+RGLED....

so i called and they cannot change it to the BRG, i'd have to return mine when it gets here, and wait another 3 weeks (i got the SSD HDD so it evidently takes longer)

1 320-1673 15.6FHD TLF WLED LCD L501X

i am under the impression that is a 1080p, WLED, is what dell told me today

they offered $150 to keep the 1080p WLED, but did saythe B+RGLED had better resolution so i might be getting a 720p *standard option* LCD for $40 more..

EDIT:

1. part number i have "supposedly" is for a B+RGLED 1080p
2. my description on my order is "not a complete description"
3. it is a "coincidence" that the term WLED IS on the incomplete description (he once suggested it meant WITH LED, but later retracted when he noticed 720p was WLED

 

The SKU description has been updated and the panel on XPS 15 is B+RGLED, not WLED. Hope this helps.

 

Would you mind explaining then, what exactly the difference between B+RGLED and WLED is??

 

hello,
i obught my dell xps 3 weeks ago and i wasn't aware about the screen thing until i saw it here so basically my order confirmation says :
1 320-1672 15.6HD TLF WLED LCD L501X
and my invoice says :
1 320-1672 15.6HDF TLF LCD L501X
and what i got was a screen with a maximum resolution of 1366x780
my question is did i get the right screen o did i got screwed.

thanks.

 

No answer... kinda what I figured. There's no difference but the name.

 

ok i just saw this post i guess that answers my question because i remember when ordering i just have one option the 720p.

Please feel free to correct me if i'm wrong, thanks again.

 

You figured wrong. Just saw your post. Requesting information as we speak. I will post back what I hear.

 

B+RGLED is FHD (Full High Definition, 1080p) B+RGLED (92% color gamut with 3 color LED backlight (red, green, blue)
WLED speaks only to the color gamut via the backlight (white LED backlight)

One difference is they are attached to different panel resolutions. The WLED offerings are HD (720p), while the B+RGLED offerings are FHD (1080p or higher). It is not that one means a higher resolution per se, but that the WLED's we offer are lower HD resolutions than B+RGLED's.

Maybe this helps?

That is totally untrue, B+RG is regular WLED, the only difference whit WLED is the name. And the fact whatever dell calls "B+RG" is higher quality, but its still WLED.

(the name probably comes from the fact that WLED is not actually made of white leds, but blue led wrapped in red-green fosfor thus emitting a white light, well, close to it)

 

Disagree with some of what you say. To keep it simple, "W" in "WLED" stands for white. "B+RG" in "B+RGLED" stands for blue plus red and green. Taking it one step further, yes, the LED's in WLED panels are not truly white LED's, but "...White LED's are actually blue leds with a yellow phosphor..." Our B+RGLED panels have seperate red, green and blue LED's. Our WLED panels have blue LED's with a yellow phosphor, which makes for a "fake white" LED, if you will. 45-75% color gamut is common to extreme limits for a WLED, while B+RGLED panels typically produce a color gamut of up to 95%.

 

Yeah, he seems to be under the impression that it's a RGBLED like in the Precision series. Oy veh.

 

If "he" is me, I am nowhere close to being under that impression.

 

can someone please confirme my answer if it's right or wrong because i was with dell costumer service and the said i got what i ordered is it true or not.

i know my question is dumb but sometimes the first step to have knowledge is asking questions.

 

Your question is not dumb. I kind of answered it in the quote above, but it is not clear that it is a response to you. So, sorry for the confusion. My bad.

You got what you ordered and paid for. The WLED screens we offer on XPS are all HD (720p as opposed to 1080p or higher FHD, or Full HD). If you want a higher resolution, you should order one of the B+RGLED screens, as those options happen to have higher resolutions- again, B+RGLED is not about screen resolution, but about the color gamut that type of display technology can produce.

 

Thanks for responding, I'm not trying to start an argument, just get an 'official' answer, and when there was no response... Anyway, if what you wrote above is actually true, then what is the difference between B+RGLED and RGBLED? I'm 99% certain that if the B+RGLED panels do, in fact, "have separate red, green and blue LED's" that Dell would market it as RGBLED, which is a term that actually means something.

 

No worries.

Now you got me. Back to requesting information. Will post back.

 

This is B156HW01 v4, the lenovo branded 95% color gamut matte screen, it's very close to the xps screen (probably v7, months later im still trying to find out what panel it is... But dont worry about that, eventually i'l find the correct datasheet...)



every single other datasheet i have (1392 right now, sorry no RGBled displays in here) says this: "LED Backlight with driving circuit design"

What im most confused about, the studio 17 display, dell advertised it as "B+RG", the datasheet, however:


Both of these displays have around 90-95% color gamut, it is true that displays without these fancy "B+RG" whatever it means name always have been stuck around 75%, even the macbooks.

 

This thread is just getting me more and more curious about the exact technological differences between RGBLED and B+RGLED (or any variations) displays. So far I've read that B+RGLED is just enhanced version of the WLED, but if that was the case, why is the color gamut of the B+RGLED so much more vastly superior than that of the WLED and much closer to that of the RGELEDs?

 

I'm still pretty sure that B+RG is an enhanced WLED. Maybe not exactly the same, but based on the same basic single-LED technology. Also, 95% is about halfway between ~70% WLED and ~120% RGBLED, not "much closer" to one or the other. I'll reserve final judgment until Bill's upcoming response, .

 

No answer yet, but I do know that RGBLED is superior to B+RGLED. Cynical Me thinks seeker_moc has it nailed, and B+RGLED is a marketing term while RGBLED is industry standard terminology. The only outlying piece to connect- in my mind anyway- is if B+RGLED is truly just "enhanced WLED."

 

Hello,
First of all thanks: Dell-Bill_B for answering me, also now my dilemma is that i bought my laptop on 12/19/2010 and at that time there wasn't any option for the 1080p display, is there a way i can get my display upgraded. or it will violate my warranty.
Thanks again.
