RGB Backlight Bleed

Where should I see it, and how much?
Want to get an idea if I'm getting a normal amount.

Mike

 

You shouldn't see any.

 

Turn lights off in your room and run black background. If you don't notice it under normal use, then you should just use it. There is no end to it if you are trying to be overly sensitive. My 2 cent for ya.

 

Just trying to figure out if things are in order.

Mike

 

None of my M17x-R2's have had backlight bleed. At least not to any degree that I'd notice.

 

I'm seeing some at the bottom of the screen and a little on the right. It's noticeable on dark screens. It's clearly there with an all black screen.

A bit frustrating since I expected to see none.

Mike

 

I have had multiple M17x's and none of them were "perfect." Same with my Dell monitors. You just have to deal with it. Good news is that it's impossible to notice when the light's on. Backlight bleeding is common with all LCD's and not considered as defect.

 

I think I found my problem. A few of the hardware diagnostic tools have ided my monitor as the CCFL version. R610K€170CT (SEC 5443).

I thought the SEC 5443 was all I needed to know I was getting and RGB LED.
Turns out the R610K€170CT also caries that designation.

Guess I'm gonna have to give Dell a call...

Mike

 

Yup chiefs.

Check out these threads for anymore info and a little read.

What does your order show up as? Do you know the part number?

 

Yup that's CCFL. No wonder you saw backlight bleed.

 

I have CCFL and I can see light bleeding, it's uniform (from light to left) in the bottom part of the screen

 

The CCFL has bleed problems. If you have to turn the light off to see it you can consider having one of the better screens actually. Get them to replace it with a RGB led and get someting extra out of it.

 

I called up Alienware tech. support and they don't have a clue. The guy didn't even know what an RGB screen was. Kept telling me that's not what I ordered, but couldn't tell me what I did order.

Sounds like I have to call the returns department.

ok sorry to be a little off topic... but is it just me or does the RGB LED screen reproduce colors VERY beautifully and vividly... but has very light blacks? i find the conventional lcds have darker blacks... and the blacks on the rgb look like an old black tshirt does after washing it too much... or is it just me?

 

someone in here posted color profiles for the LED display, try to find them cos color profiling is a very important part in the game, actually is like having a ferrari with a badly tuned engine

 

in all honestly... although i consider myself a M15x veteran... i'm a compete M17x noob... i just got it 2 days ago, and haven't even had the chance to really tinker with it (working like an animal lately).

So yea i have no idea what you mean... are you saying the RGB black darkness levels can be improved by playing around with the color profiles? and who might i ask for good profiles with the RGB properly tuned... as i've read it has to be tuned, but i haven't seen any posting about proper tuning yet... mind to help me out? theres alot to absorb in just a couple of days ... I'm still trying to learn about the issues/fixes for this beast... and trying to get to know the machine better.....

 

it's here and welcome to the m17 Forum

Thanks buddy! Will rep ya when i'm aloud

 

I'd love to see a side by side photo of the m15x and m17x, get an idea of RGB vs WLED.

Mike

 

So if there's any backlight bleed at all, it's not an LED?

 

I don't know that I would say that, but if there is, I'd make sure to check the part number.

You can use a number of hardware info tools. I used hwinfo32

It doesn't tell you outright that it's CCFL, you have to know the part no.
+ R610K€170CT (SEC 5443)

backlight bleeding is common in all LCD's, but different types have different bleeding ammount (LED Backlight has very few as an Eg.)

 

Hello all,
I just got my M17x R2 a few days ago. I have few questions regarding RGB Screen too. I think the color looks great but the black level look just like what Jstarnino said "old black t-shirt". I also find that the brightness uniformity is uneven. If I put the screen on all black, I can see that some part of the screen will look brighter and some darker. I can also see very small amount of light bleed from all 4 edges. I have a sony laptop with wled screen and it doesn't have any light bleed from the edges at all. I was wondering if anyone have same problem or I got a faulty screen. Thanks!

 

I'd be curious to know too. However, I wouldn't be surprized if you don't get a perfectly black screen. It probably has to do with the fact that the RGB screen is so bright. Making some picture adjustments might help address that problem.

As far as bleed, I don't know, haven't seen it in action, maybe Joker will chime in. I'd suggest making sure you have the right LCD by checking the part number via Everest or similar tool.

I ordered mine with RGB, but ended up with CCFL. It was probably due to an Outlet clerical error.

Mike

 

I really wish I could find any sort of comparison between the RGB and the CCFL. I tried googling everything I could think of and tried searching the forums but could not find a single one with pictures and good comparisons between the two. Maybe it’s partly because it’s hard to show the difference in photos being viewed on screen? Or maybe it’s my searching ability?

I just ordered one and decided to go for the RGB but I’m worried about the few comments I’ve read about black levels. That is probably more important than color quality or brightness for me since in games the screen can be black quite a bit depending on the game. Many times it seems like people can’t tell what they have anyway so was it even worth the cost? I just wish I knew what to expect. I guess it doesn’t matter much since mostly I will be plugged in to an external anyway. However, I’m not thrilled about “wasting” money though if I made the wrong choice.

 

Oles.

A side by side pic of my R1 and R2 CCFL vs RGB LED screens.

I'm the worse photographer and the pic doesn't do the LED any justice. However just something for you to look at chiefs.

Cheers.

 

Thanks for the pic... It does show that the RGB can do more color than the CCFL. I can't really tell if blacks are an issue on the RGB.

Mike

 

Which one is which? The left one looks brighter but the colors look like their overdriven. The colors on the right one look more accurate, but not bright enough. Might just be the photos though, I know it’s hard to take a realistic looking pic of a screen, only to be displayed on yet another screen. I’m not even sure which one I like better from that shot, lol.

What’s your opinion since you have had the pleasure of having them both side by side?

 

Yeh the LED one is much much brighter compared to the CCFL screen. The 1st 2 main things you will notice are the brightness and vibrant colours. As for the blacks they seem fine to me. Deep and very vibrant.

The CCFL screen though is still very good and agreed that the colours are perhaps more accurate as they are less vibrant and bright. However I would still go for the RGB LED every time lol.

Cheers.

 

Hi there chiefs,

The left sided one is the RGB LED screen and the right one is the CCFL.

In person they both look great. I really like the RGB LED one however. Seeing it in person just blows you away. Once you look at it closer up it is just WOW. The sheer brightness of the screen and vibrant colours may kill the accuracy of the colours as compared to the CCFL however if you turn the brightness down a couple of notches that can fix it right up.

I personally love the RGB LED screen and its super brightness as I mostly use the machine in brightly lit rooms or where sunlight shines in through the windows. So having this screen is awesome.

I used to enjoy the CCFL screen too though. That was tip top before I saw the RGB LED one.

Cheers.

 

Cool, thanks! I would never completely judge a display from a picture, I just wanted some reference. The brightness is really noticeable assuming that they are both at same settings (max or min etc). I know there is a color calibration thread around here so that doesn’t bother me too much. It is nice to know that the CCFL is still a good screen. Knowing my luck they will give me the wrong one!

 

Yeh both screens were maxed out brightness.
I do notice though that like all of the older LCDs; the CCFL one does need a little time to warm up and become brighter. Like to hit full max brightness potential.
Whereas the LED one BAM just instant super bright self always lol.

Cheers.

 

Yeah, I must say I was impressed with the CCFL screen, it was good for CCFL. I wonder if it's also an 8-bit display.

Regarding RGB Colors. If you where to put up a color ramp on both screens, can you more easily distinguish the shades on the RGB? Nokia Monitor Test is a good way to check.

Regards,

Mike

 

Tried the Nokia test chiefs. Saids I needed 64bit version or something so I couldn't run it unfortunately.
The colours on the RGB LED are fine really; just they are very vibrant as compared to the CCFL. You could say that they are super bright. For the CCFL though the only thing it was lacking was more brightness. If that was able to match the LED brightness then OLEs. Although we do know that LED backlighting is brighter than standard LCD CCFL backlights. Thats one of the perks of LED backlighting to begin with.

Cheers.

 

i got the same thing reborn. it says check your operating system for the correct bit version. but i have 64 bit windows, and that's the 64 bit program. someone made a mistake there haha.

 

Ehahaah yeh I just went back and double checked to see it was or stated that it was 64bit version LOL.
Thanks for the confirmation.

Cheers.

 

I was having trouble running the program, but had luck running it from inside the zip file. I don't know why, but if you can try view archive then double click the app inside.

Mike

 

There's two main benefits of the RGB LED screen: >100% color gamut and it's >300 nits which makes it as good as modern day HDTVs. I have an HP DV6 next to my M17x right now and the difference is night and day.

 

Ehahah yup ever since I saw this RGB LED screen I am thinking all future purchases where screens are concerned must be LED Hmmm maybe I should have bought that dell 24 inch LED last week which was on special for $198 down here. Its gone back up to $300 odd. Oh well. I think I want something bigger in the future.

Your right though chiefs, it puts Sony Bravia in the lounge to shame LOL.
I love the brightness of this screen. So soooooo awesome. I can use it anywhere now.

Cheers.

 

Hey there chiefs,

Yeh I tried running it that way as well and it failed. Not sure whats going on.

Cheers.

 

Dang, if it’s really that good I may be tempted to not use a larger external (cheapo one) and try to live with the laptop screen.

 

Since you've seen both m15x WLED and m17x RGB screen. What's your take on the PQ difference? Would you say one is much better than the other? How close would you say the PQ is between the two?

Mike

 

hey there folks.

My RGB screen has backlight bleed in the bottom( where the taskbar is). starts from the right edge and ends to the left . its very noticable when the screen is black. its like a soft blue line.

do u know if this covered by warranty?

 

So bringing back this threat to answer my own question to let everyone know

that yes the issue is covered by the warranty. AW replaced my screen as it considered as faulty because of the bleed.

 

I think every M17x RGB display has bleeding so replacing it wont do.

 

I just got my M17 on 11/16 and have noticed zero bleed. It's easily as good as my Macbook screen which I've held as the gold standard...till now.

 

You guys might want to check out this thread regarding the RGBLED: http://forum.notebookreview.com/ali...ely-calibrating-m17x-r2s-rgb-led-via-ccc.html - Crylo has put up some configs to get the best out of our screens....it is obviously, down to the individual "owner of the eyeballs" but i think it improves the picture no end....its more life like and realistic and not quite so bright....

Regards to bleeding, the only time i thought it was an issue on mine is maybe at the logon screen...perhaps a little too bright around the bottom left and right corners of the screen....but this is backlighting here so i wasnt expecting a 100% black image to be displayed....i ould imagine to achieve that, the panel itself would have to be an IPS panel......

 

Macbook Pro DOES HAVE backlit bleeding. Currently there is no way to have non-bleeding backlit on laptop display I believe

 

It's all about uniformity of backlight. Some are even(what we consider good) while some aren't.
