T400 LED brightness & calibrated profile

good deal. i was scared your calibration was for a Samsung panel =)

 

so, anybody lucky with this calibrated profile starting auto-magically on vista ?

 

if you read through my posting in this thread, you should be able to find the info you need.

 

yeah, I know what you mean. I read this thread like 5-6 times.

The MS hotfix is installed and the profile is selected as default ( 6500, reddish on ) but everytime I restart windows it doesn't load the profile automagically.

If I go to DisplayProfile and double click on that reddish profile the screen becomes more reddish - it effectively applies the profile you created. For which I am thankful.

Can you please suggest sth, maybe I am missing sth.

 

assuming you've followed my instruction on page 2 and set the default profile to the one you've just downloaded.
If you're using integrated graphic card as i do, do the following

If you're using discrete graphic, I'm pretty sure that you need to disable ATI Control Center on startup from starting up(I don't remember the name of the service, but you can find it out in "msconfig"->"startup"), maybe 1-2 more other related services as well.

Basically what you need to do is to disable the graphic card software on startup to prevent it from resetting your the LUT value whenever it needs administrator permission or wakeup from desktop lock, sleep, hibernation, etc...

hope this helps.

 

shinew, ok, I know what you are saying by saying that the intel/ati staff is trying to load its Look Up Table (LUT) at the start. But, I disabled those three apps from running on startup from the registry Run field - so I don't have to use msconfig. It is the same staff, I know.

Look, removing those keys from registry doesn't mean that you get rid of them - still the intel staff is loaded - right click on the desktop - you will see the intel customized "Graphics Properties" from the menu. It is still loading all that staff even with registry keys deleted. So, it is still fighting for the LUT. And I see this - just after login screen is reddish (the 6500K profile is reddish and is supposed to be the normal daylight temperature color) and then it becomes bluish at some point, almost immediately.

so I do not know how to make it not load the intel staff

 

I don't think you know what I'm saying. You need to disable the services on startup to prevent the software from resetting the LUT. If you're using integrated graphic card, just follow my instruction and it'll be fine, editing registry won't work.

 

shinew First of all, there is nothing special in your post on second page of the thread. BTW, you know that every service in Windows has its associated registry key as well. Everything in Windows is stored as registry entry. And the registry is stored as a raw file called SAM file…
Strictly speaking, those three intel applications are not windows services at all. It is just they are standalone executables that get loaded by Vista at startup because of the registry key: HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Run
They got there at the install time by the driver installer.
You are referring to msconfig application. It does the same thing when you disable a particular application to run at start time – it simply deletes the key from registry.
I told you right ? I deleted those three intel applications. So they are not loading. But problem is you cannot completely stop intel staff from loading by deleting those keys.
If you think that you prevented intel driver from loading its LUT – go check it. Right click on the desktop and see that there is a menu, not generic windows menu, but intel’s staff – Graphics Properties. That means that intels drivers and libraries are still loading at startup. It means that they are still loading the LUTs. You can check this by executing the DisplayProfile and double clicking the 6500 icc profile that you were helpful to share. You don’t even have to switch to 6600 icc and then back to 6500 to actually load the profile. Just double click the 6500 one after fresh reboot and see how your screen gets more reddish.
That is my point – windows is still loading whatever it is loading but not your profile. And it really sucks.

 

if you click on "Graphic Properties" by right clicking on the desktop, you will restart the intel graphic driver software and it will reset the LUT, you'll need to use displayprofile or restart to bring it back to the default profile. But why would you want to do that during normal use?

I'm certain that I'm loading the correct profile, 6500K & 6600K are very different that it's easy to tell. One could also confirm it easily with display profile.

If your laptop wakes up and it displays the correct profile briefly then immediately gets reseted(I had the same problem bf disabling the services on startup), that means there is still intel graphic related services running in the background. By disabling those 3 services on startup, it solved my problem. It seems like you're also using the integrated graphic so there shouldn't be any reason why it won't work for you, yet you're insisting on trying to do it your own way without success. I can only hope you can work something out. good luck.

 

no, now you didin't get it.
Look, the intel staff is loading completely different profile - not yours 6600 blue one, ok ? it loads whatever default WCS profile it has. That is it. It really doesn't matter do you right click it or not - it simply loads its default profile and not the one you think it is loading...

 

i give you props shinew. it took about three postings from this guy before i was able to read into his intentions. i wouldn't have made it to three postings before writing him off as rude. + rep point for you.

if they are all that constructive,...just think about

shinew, still open to constructive discussion, if any

 

hi, i look at the calibration for the t400...
will it work with my T61 with 14" WXGA+ ?

 

Thanks rxblitzrx!

unless you're using intel 4500MHD integrated GC, LG panel with LED back lighting, don't bother. It'll not be accurate enough to make it valuable to you.

 

hi, shinew, I want to use your profiles but found the links are unavailable.
Could you provide again in other available links?

Regards.

 

hey,heavenfire
email me,i will post it to u
[email protected]

 

I could just access the links just fine, maybe your ISP/country is blocking it? I'm traveling at the moment, I can upload it to a more permanent location once I return home.

 

I found the links available later (maybe it's due to my ISP...) and I have downloaded them. Thank joey and shinew very much.

Regards.

 

Just curious b/c notebookcheck stated the new macbook pro screen is 370!
I don't know much about luminance, but everyone states that the T400 screen is amazing. I always like the brightest screen possible (for watching movies and stuff)

 

the maximum brightness on my t400 is around 270, so the t400 is probably not as bright as the new macbook pro. although i usually use it around 100-150.
btw if anyone is bothering profiling their monitor and care about faithful color reproduction, the screen should not be too bright.

 

Anyone think it's worth waiting for RGB-LED displays? Right now I'm not too happy with LED displays and CCFL displays offered by Lenovo but then their chassis are more "business quality" than Dell's. That's all I want: a well-built chassis and a nice display - hard to find.

 

Thank you for calibrated screen profiles.
I am T400(WXGA+ LED LCD) user.

But sometimes it is restored linear gamma data. (at Hibernate/Stanbay/FastUserSwitch/UAC-elevation, or etc...)

I have developped "auto_lut" that reloads/reflects gamma data at those events.
I have opended to public this software in sourceforge. (as public domain software)

http://sourceforge.net/projects/auto-lut/

Thanks,

 

Been looking for something similar myself and frankly it seems the only think out there that meets those specs is the 15" Macbook Pro. And I dont want a Mac.

Hard to understand how it has come to this. One would think that Lenovo would have offered at least ONE hands down, outstanding screen option with their high volume-high profile product. What a waste of a marketing - and profit - opportunity....

 

at this point it is probably worth waiting to see if lenovo offers a decent led screen for the t-series with their t410/510 update in january

if they don't offer something then, it is fairly obvious they just don't see thinkpads as needing decent screens

 

Is there any for for Win 7? Thanks

 

any what?   ICC profile?
