Studio XPS 16 1080p RGBLED Settings?

Yeah I see that too.

I think it's a trait of these screens.

 

Still waiting to pull the trigger on the 1640 with RGBLED...have been reading these threads for almost 2 months, and the color accuracy bothers me..starting to think save 250 and get the wled.
Color aware programs sound like they are fine, but non aware programs, and the windows gui are oversaturated from what I read. I have read conflicting reports about windows 7 being color aware...
Also everybody says to calibrate the monitor..does this have to be done with a external sensor, or can it be done with a calibration DVD

 

i have read many online reviews and seen and talked to many sxps 16 RGBLED screen owners and none of them have expressed any concern about the colour accuracy. so im not sure if this problem is just evident in a few screens, or most people just dont notice the colour inaccuracy.

 

It's mostly a matter of can you live with the incorrect colors or not. I've learned to live with it. I took the overall color saturation down in ATI CCC to get the Reds a little better under control, but you lose the vibrancy of other colors. It's pretty much a compromise in one way or another. I would get the WLED myself since it's cheaper and I bet the colors are spot on.

 

Hi all

Sorry for not having been able to answer before
My profile is ok with my (european) copy of the XPS 16 1080 RGBLED screen (I'm not home right now so I can't check your Coca Cola picture Limstift, though).

However, make sure that:
- your web browser is color managed (Firefox 3.0 and 3.5 are, but you need to manually activate the support)
- don't mess with Catalyst Control Center (put everything back to default values and don't ever use it when an ICC profile is used)
- you should have a LUT loader: that program will adjust the gamma curves of the video card, based on information stored on the ICC profile. Even if you tell Windows which ICC profile to load, it won't upload the LUT to the video card (I've read somewhere that Windows 7 RC1 might finally be able to do it without requiring an external loader, but I have to check this). Anyway, this is easy to check: when logging in, you should get your screen colors automatically change a couple of seconds after logging (per channel gamma correction); if you don't see anything happening on that front when logging in, find a LUT loader...! (the one that comes with Eye One is "Logo Calibration Loader", but others should work too).

So, for the others that don't know how the ICC profile should be used:
- feed Windows with that profile (depending on the version, it's somewhere in the control panel / display properties or whatever)
- lower your screen brightness to 40% (I use the Fn+arrow keys for that)
- get a LUT loader (needed for all versions of Windows, except maybe Windows 7 RC1 --- to be confirmed)
- configure your applications to use that same ICC profile (Firefox, image editing software...)

 

i called DELL and complained about difficult colours on my RGBLED. they send a technician who will replace it to a WLED screen. (i got a free 9-cell battery for the lost money between WLED and RGBLED, so thats OK)

ive seen my friends WLED screen on his Inspiron 17" and it had actually more accurate colours......im happy i did this choice

 

Firefox 3.5 by default uses ICC on all tagged images.

cedm what does red and green look like for you in the color wheel that was posted a couple of pages back:



They look awful on my screen with your ICC active - why would that be?

 

wow, just a battery to make up for the difference?

 

do like me. change to accurate WLED screen.....

think RGB technique is little to new, after they fix this issues, RGB will be awesome .
(but then Toshiba comes with their OLED screens who will be even more awesome )


@vin200.........its really OK, it was myself who said it was OK. i dont bother to nag about more. DELL have been sooooooooooo generous in the past.

but, if there is some who actually comes up with a good way to set this colours. i will of course keep the screen.

 

Everything looks perfect here (on both Windows 7 RC1 and Ubuntu). Do you have a LUT loader? (it is mandatory)

I didn't look at the image profile of your chart (it might not be tagged, which might also explain a lack of accuracy).

Something to consider also: you have the XPS16 with the 4670 video card; I have the 3670. The output of both video cards might be different.


Otherwise: the RGBLED screen is a must; it's gamut is really impressive. People who are serious about colors should get that one (but calibration and profiling is needed, as all other screens!)

 

cedm: Where can I get a LUT loader? I have the 3670, and the colors doesn't look good with your profile.. Isn't the LUT Loader just a program that loads the specific gamma value at start up of the OS?

 

first of all.... The human eye can see 7,000,000 colors,(and some of these are eyesores). so 16.7 millions colours is far to much for a human eye to perceive.

so everything from Nokias 16.7 million TFT screens to RGB is basicly overrated.(in fact when you look on a movie with a RGB screen all colours blend in in each other and create similar colours as on a 262K screen, just more nuances).

 

Limstift: google is your friend I use Logo Calibration Loader that is provided with Eye One / iMatch, but others should work. Under Linux, I use xcalib, which also seems to be supported under Windows (I don't know if other tools would be better than this one).

KSMB: you are missing something. Even if a screen advertises 16.7 millions colors, it does not mean that it can produce, for instance, all greens that the human eye can see. 16.7 millions colors does not mean that it can cover a useful and large range of colors. That's where the RGBLED screen of the XPS16 is useful: it's color range is much larger than usual laptops (the other nice laptop screens currently are: the new MacBook pro 17 and a 20" AW Sony; that's it). When I look at a photo on my RGBLED screen (converted from RAW to an Adobe RGB color space, wider than the usual sRGB), it's really just like looking out of the window (and not at some kind of lavish postcard).

 

well, when i compare my True life wxga+ to my RGBLED i see no BIG different in colours. they looks just a bit different, no major plus on the RGB actually.

maybe its because this RGB screen does not have 100% accurate colours, i dont know. (im convinced that the RGB can become best, every reviews says so)

i do know that nearly every people have bought the RGBLED screen with a lot of expectation (even me)....he he

 

but most people are really amazing by the screen. just a handful of people (mostly in this thread lol) seem to not like it.

 

can someone with a decent camera (preferably DSLR) upload their RGB screens with a colour spectra test image....please

@vin200, can you upload your screen with some cool colours ??? (just want to see how it looks....cheers)


for example, download a Coke can-image on your RGB screen....does the Red looks good or perfect ?????
(best way is to have a Coke can in your hand and then compare it to your RGB screen, then you really see how close you are)

 

It's a 1500.00+/- laptop guys, designed for some good gaming capability and all round computing. If your going to micro-analyze the color spectrum of the display and nitpick every nuance with scientific instruments and calculations than maybe:

YOU SHOULD GET A DIFFERENT LAPTOP. SPEND THE MONEY, BIGTIMERS.

Because this is one of the best displays available on a relatively powerful inexpensive laptop. I'm sure 95 out of 100 people think the display is great. Find something as good as this for the money...buy it. I couldn't.

 

cedm: I installed the software that comes with the Eye One-unit, and the results are pretty good. The LUT Loader (Logo Calibration Loader) really does a good job with the colors, they're more accurate now. My only worry now is that the temperature or WB seems a little too warm. Is there someway to make the temperature colder, or is that information stored in the ICC profile? The whites are even more yellowish/brownish now.

 

Has anyone else noticed when you first turn your laptop on the Dell logo on the POST screen has a black background. It's as if that black box is a lot darker than the rest of the blank screen around it. When the POST screen and logo disappears the screen stays at the grey blacks rather than the nice inky blacks of the Dell logo background.

Could it be that the wide gamut of this screen is messing up our black levels and we are actually getting dark grey instead of black?

I'm sure blacks are not what they should be on this screen.

 

iaTa: I agree, but don't dare to criticize this laptop or all the fanboys will soil themselves & cry hard.

 

Why would the post screen be used as a reference for "true" black?
When I use a black background in paint or some other graphics background it is as black as black can be. Much darker than the post screen. I'm not understanding why you are using that as a reference.

 

Because the black that I see on the POST screen, windows loading screen, paint with black fill, movies etc etc are all grey black - not proper black. There must be something about that logo which is making the screen display its true black. If you see what I mean. Something is definitely squiffy here. I'll try and get a picture of it.

Blacks are so important on a multimedia screen and in its current state the blacks on this screen are crap.

 

i still think the screen looks great but yeah unfortunately black levels are very noticeably sub-par

 

No I'm talking rubbish about the Dell logo - the POST screen is just brighter (almost a greeny colour) as someone mentioned earlier.

Still the general black levels aren't good though.

 

Black level: Reduce brightness (to 33-40%). First the screen might appear a bit too dark (by comparison with 100% brightness), but as soon as your eye forget about the previous state, things get back in order

Limstift: indeed, compared to the standard state, loading the LUT with my profile gives warmer colors (in fact, colors are a bit too cold by default). I have kept by purpose the native white balance of the screen (it seems to be a good practice when calibrating/profiling laptop screens). You will get used to the new white balance quickly.
Otherwise, you may want to try this other profile which has a forced 6500K white balance (don't forget to re run your LUT loader or rebooting when assigning a new profile on Windows) -- see attachment.
BTW: don't forget that Windows is not color managed; so your Windows deskop/menus/borders may shift to inaccurate warmer colors, but color managed applications (those who can use the ICC profile) will display accurate colors

 

You don't need a LUT loader with Windows 7 as I've just found this:

http://forums.macrumors.com/showthread.php?t=651014

That changes my whole OS on the fly, not just colour aware apps.

Now to get testing these profiles.

EDIT: There is something wrong with the white balances of both profiles. Even the 6500K profile is a lot warmer than the default Windows sRGB profile? Also the red on that colour wheel is still very orange and washed out?

EDIT: Some whites are cooler with the 6500K profile (like in the Windows GUI) but whites in most photos are a lot warmer. The screen also loses a lot of vibrancy using the 6500K profile.

EDIT: The reds in most of my photos are a lot more vibrant so I don't quite understand why the red in that colour wheel is so washed out. This colour profile stuff is pretty complex isn't it.

 

im a HUGH DELL (& Sonyericsson) Fanboy and im actually able to criticize me own laptop, (usually i have major problems to even say one bad word about my laptops....he he)

the RGB screen is not 100% accurate...period. (but thats many other screens as well)

 

iaTa: you are right, by following the procedure of the link you have provided an external LUT loader is not needed anymore. Good! And regarding the white balance: nothing is wrong with the profiles it's just that your configuration seems too distant from mine (esp. the video card).


KSMB: no screen is 100% accurate unless calibrated and profiled. There is nothing wrong with the RGBLED. Period. You may have some personal issue with it, that's _your_ problem.

 

What are people using to calibrate this screen? Hardware or DVD...It seems crazy to have to buy a hardware screen calibrator for hundreds of dollars just to get this screen right...

 

@cedm..........think you both right & wrong.

think this RGB screens NOT are 100% properly manufactured. (sure, the best calibrating software in the world would maybe fix the screen almost accurate....but ive tried good calibrating softwares)

one thing i actually think might works better is to use a hardware calibrating method. (done with a special type of sensor). example, NECs MultiSync Photo Edition. anyone who have tried this type of calibrating ??????

 

I think it would be nice if calibration tools included RGBLED as a screen option rather than the basic LCD/CRT selection

 

Hey, I'm gonna start using Photoshop and everything on my new SXPS and I'm kinda new to photography so umm... What's an LUT loader? Has anyone found a way to make the colors more accurate? I mean what I did was but Brightness at -35 and saturation at 80. But if there's better settings, tell me Thanks!

 

To get a properly calibrated and profiled screen, you need an external hardware probe.
Software calibration tools may help a bit, but it's nowhere close to hardware solutions.

 

Finally I've reached the level of accuracy I aimed for! I used the profile posted on the board earlier (GMC - Dell Calibrated 1 19-04-09.icm). I've tried several others, but this one proved to be the best with my specific panel. To get it working properly you should download a LUT Loader (the one in Windows 7 doesn't work good enough). I downloaded the calibration software that comes with Eye One (hw calibration unit) which also includes the LUT Loader called "Logo Calibration Loader". You can find it at http://www.xrite.com/product_overview.aspx?ID=758&Action=support&SoftwareID=724

 

Where is that ICM Limsift.

I've searched but I can't find it.

 

Here you go

 

Cheers bud I'll give it a go.

Out of interest why do you say the Windows 7 LUT loader is no good?

 

I've tried it and it doesn't give the same accuracy. The Lut Loader I mentioned does a better job.

 

Ok I just tried that LUT loader and it produces exactly the same results as the Windows 7 method that I posted on the previous page.

Also that profile that you posted is awful on my screen - white's are so red.

I think I'm going to go back to using no profile at all. cedm's profile is the best out of the bunch and does make photos look really good but it puts some other things out.

EDIT: Hmm the plot thickens. Reds in Firefox just didn't look right with cedm's profile and as we are using a LUT loader / Windows 7 method I wondered if the profile is effectively being applied twice, once by the LUT loader and then again by Firefox. So I disabled colour management in Firefox and everything looks spot on now - no more orange reds and washed out greens. Why was this happening as surely I shouldn't have to disable colour management in Firefox?

 

Hmm. That's strange because I'm not able to reproduce the effect of the LUT Loader with just using the Windows 7 method. Actually the Windows 7 method makes no difference from just having it deactivated (and no LUT Loader, just the color profile).

Anyway, cedms profile when using the LUT Loader produces a more greenish/yellowish whitebalance than the profile i'm using. I ended up with that one mainly because my RAW photos looked more accurate. Yes, the whites are a bit redder, but I think that's better than the yellowish/greenish whites that comes with cedms profile. Anyway it's impossible to get good whites with this screen, seems like the RGBLED has something to do with that. Even my iPhone has better whites when compared side by side. The uncalibrated whites aren't better so I don't see the point of not using a color profile.

I have color management enabled in Firefox and it works great. I'm just using the LUT Loader, no Win7 method.

 

Can you please explain me - how exactly you fix yellow white problem?
my screen has the same problem with yellow white.

 

You won't get perfect whites with this screen and that's basically because of the RGBLEDs. I've a more "reddish" white that I find more comfortable, but that's of course individual. You can try downloading the profile I posted earlier along with the i1match suite which includes the needed LUT Loader.

Good luck

 

Your eyes do adjust to the white levels. I'm using cedm's profile permantly now and the screen is just stunning. The black levels do let it down a tad but as was stated a couple of pages back if you turn the brightness down a bit they aren't too bad.

Overall I'm pretty chuffed now. Thanks to all.

 

Does someone know if it's possible to edit the values in an ICC monitor profile? It could be interesting because one profile gives me perfect greens and a another one gives me perfect reds. If I could manually take the gXYZ values (greens) from the profile with good greens and replace it with the corresponding values in the profile with good reds, I would probably (if i'm correct) get good greens and reds in the same profile.

Anyone?

Thanks

 

Ive also been playing around with calibration on this screen for about a month. Im not not 100% happy. I have the spyder2 pro calibrator and software which has given me confusing results.

- Reduced saturation on CCC to 70. Left everything else as default in there. Then ran the calibrator and it just seemed to warm everything up and told me to increase the backlighting to about 35% (using fn arrow keys)

- Left everything as default including saturation then ran calibration. Result, horrible. Everything was still over saturated but just warmer.

Clearly I have no idea how to use this calibrator with this screen. I thought I could just set the CCC settings default, in fact the every setting to default, run the calibrator and BANG its perfect. I was wrong.

Can you someone please explain how CCC and Sypder pro work together?
What settings do I leave CCC on, or can I just disable that whole thing and let spyder2pro do it?

confused... very confused.

 

I did same and am really happy with mine. It is quite stunning. All the CCC controls are set to default - including saturation - and brightness is at 40%.

 

I've been reading this thread for opinions if the RGBLED is worth the extra money.

I've been reading that the bios firmware update also improves picture quality. I wonder if anyone can test this?

 

bilsy1982: not sure why you get those results. could you post your ICC-profiles? would be interesting to test them on my own panel.

 

Could anyone explain step by step how o adjust the settings (ICC/CCC)? I am new at this want to know how to calibrate the screen to get the most/best out of this monitor.

 

when, i turn my brightness below 60%, my screen flickers ever so slightly once on a while. does anybody else have this? its kinda annoying. its almost not noticeable but still annoying.
