hmm how are you able to clone monitors with different resolutions ?
HP LP2475w, IPS 24" Official Thread! (Now Available from OcUK)

Via the Nvidia control panel, I had the HP as my primary, and the Compaq as secondary. The Compaq was actually displaying the same 1920x1200 image, but it involved a "pan and scan" feature (following the mouse), which meant it was only displaying 1280x1024 section of the full image at any one time. Simply selecting "clone mode" did the trick for me.
I thought it was necessary to have both running at optimal resolutions to get fair results. Selecting the Compaq as the primary monitor forced the HP into an equivalent resolution, which wouldnt have worked for the test.

Some hope perhaps after all
Maybe if its good with just abit of tweeking one can get away with it at 1st and then perhaps buy a calibrator later on
Correct. Spent a couple of days tweaking mine by Mark 1 Eyeball and have never touched it since. Great picture without any further outlay.

What brightness level did you leave yours on?

Finally settled on 15-20. Quite a drop from the default of 90!

I set mine to 20 also. My new desk comes tomorrow, will send pics once setup.

Its not too bright is it? I mean one can set it so its fairly dim.... I only ask since I prefer low light in my small cave like room lol

default is too bright but lowing to 20 is perfect.
I have 63 backlight hours clocked. Does anyone know if this green-to-pink colour variant goes away over time?
It's the one thing holding this monitor back from perfection, in my eyes. Not enough to warrant a return, but it's a constant distraction when working with Word documents side by side (with one page being darker than the other).

Same preference here, one reason for buying this monitor was it's low brightness performance as assumed from the tftcentral review. In this post ( http://forums.overclockers.co.uk/showpost.php?p=12689686&postcount=548 ) I measure 82 cd/m2 at a brightness setting of 20. Iirc brughtnes = 0 equates to a measured value down to somewhere in the 60's, which is dim for even a CRT. At this point absolute purity of white suffers a little but contrast remains good and the monitor remains quite usable.
In my case after a couple of hundred hours I'd say no. The left side is less blue than the right and while I hardly notice it in day to day usage the difference is definitely still there. When I spoke to HP about it they seamed more than happy to arrange a replacement, so I'm giving it a couple of months while LG sort out their production / quality control. It's a gamble but I feel the pro's of this monitor make such a gamble worth while, worst case I keep what I have which I'm generally happy with

Get a replacement. I use mine all the time for reading pdf's - it's one of the main reasons I upgraded to a larger monitor, so I could have two A4 pages side-by-side. I have absolutely no colour or brightness variation across my screen; no striping, either, our any of the other problems a few people have listed.
IMHO, your monitor is faulty, so try a replacement. Nothing to loose on such an expensive bit of kit.

Brightness greatly depends on how much ambient light there is in your room, I have 2 profiles saved in HP DA for this very reason (one around 1-5 brightness for when the room is very dark, and the other around 17).
Sent my first one back becuase it was fairly bad, replacement also showed the issue, but not to the same extent. By around 60-100 hours it was gone completely, and it's stayed that way (currently at 479 hours).
Right then. I'll get in contact with HP and see what they have to say.
It's nice to knownthere are some people who dont have any issues with it at all. I just hope they're not the minority; if I keep having to send monitors back, I may just as well grab a refund, wait for the next Hazro update, and save myself a heacache or two along the way.
As it is, I'd prefer the screen's tonal shift to simply resolve itself, but there's really no guarantee. I have no idea how bad it is compared to other peoples'.
Would leaving it on a white screen for a couple of hours, at full brightness/contrast, burn a consistent tone across the screen? Could that be a solution?

Well, I guess it's worth a try, but the "green-to-pink colour variant" across the screen just seems plain wrong to me.
I'm at home now, so sat in front of the HP once again. I've just loaded a few pdf files (viewed 2 pages across the screen at the same time) and checked hard for variation of colour, contrast and brightness across my screen. There just isn't any. FWIW, I have Brightness at 15, Contrast at 60. Not sure what yours is running at?
Like I say, you can try some "high settings" for a while, just to see if it improves, but it sounds as if something is wrong to me. Any chance of posting some photo's of what you are seeing, and maybe a jpg of the backdrop you are using to test it with (i.e. a photo, or Word doc. or something.) I'd be more than happy to try it on my HP and report the findings, if that would be of any help before you send it back.

Someone spoke to an LG.Display rep at an electronics fair recently and this is not a fault apparently, but something that is meant to go away with prolonged usage (which in my case it has).
I have a photo of this green-to-red colour shift. As always with these monitor photo shots, it's hard to really capture a problem as subtle as this. But here goes:
I set my screen to full grey, with low contrast and brightness. You should see a green tint to the left, and red to the right.
The photo isnt as accurate as I'd like, but it's the best I could get without inducing the "rainbow effect" in my pictures. To my eyes, the actual screen isnt anything near as bad; the red seems highly exaggerated in this example. I found it impossible to get a clear shot, but you should see a murkish green tone to the left, and a slightly crimson tone to the right - both are quite subtle, but when you compare one end to the other directly, it should be obvious. For those looking to recreate the effect, these tones will usually show up particularly well on constant greys and whites, with any brightness/contrast setting. Just for reference, my colour settings are R:235, G:220, B245.
IRT nomadd: I believe you when you say you dont suffer from the problem; by now, you would have noticed it in one of your pdf's. Thanks for checking though.
IRT philjohn: Do you by any chance use high brightness/contrast settings, and work with spreadsheets often? If so, this could have facilitated a faster burn-in, and helped standardize the colours much faster, due to the fact your screen is constantly working with the same colour (white). I'm on 85 hours now, and for the most part I've been browsing websites, playing games and watching movies with it, all of which involve an inconsistent and active use of different colours. In this time, there's been little to no change.

I see some feint green in the upper/bottom left corners of your picture, viewing with a calibrated crt. I can only see a slight blue tint on the right tho.
@cataferal,
A quick edit for you, nomadd is the problem free pdf person
As sadbuttrue, I see a blue shift to the right when I view your pic on my CRT but my colour vision is not the best.
A good way to expose the problem was mentioned way back in this thread, view the BBC main web page full screen giving white borders left and right with a good splash of colour in the middle of the screen, or indeed just place anything that breaks up the background colour in the middle of the screen. This prevents the brain from 'smoothing' out the colour transition.
Anyway, your picture is similar to what I see with 360 hours on the backlight clock.

Hiya,
I received this monitor last week, and it displays the same mild pink/green cast. I have tried to photograph it...
And the two shades side by side...
Obviously there is only so much that the camera can show, and to be fair I only see it when I look for it, but will use it more to see if it goes away

Good photos! My screen looks exactly the same. I'm really confused as to why they let a problem like this through the QA process - particularly for a business, wide-gamut (typically photography orientated) monitor which is therefore advertised for it's colour accuracy.
IRT ecat: Absolutely. I have the BBC News website set as my homepage, so every time I open Mozilla i'm reminded of the problem. If you're on 360 hours with no change, It doesnt bode well for me...
(also, edit made).
I'm not going to whine about it any more. I think it'll just have to go back. It's looking quite likely that I'll end up with the same defect, but I'll just keep sending them back until they get it right.
