I am really struggling to get this monitor calibrated properly, i don't have a calibrator, and have just been adjusting values that people have suggested but it always seems to have a red tinge to the screen, any ideas? i loaded the LUT manager up and used the file that Philjohn recommended but forgive my noobness i don't know what the LUT manager does? have i set this up wrong?

I know this is a silly question but have you tried using the monitor controls to turn down the red ?

Even with a colorimeter attached the first part of the calibration is to manually tweak the red, green, blue to give the software an even starting point. So tweaking is a valid fix

It's worth pointing out that the calibration settings for one monitor may not yield good results on another monitor. After all, if all monitors performed exactly the same there would be little need for 3rd party calibration devices.

So yes, using a profile from another monitor can be useful, as a starting point if nothing else, but it is not a panacea. If I have time tonight I'll post my calibration, it may work better for you, it may be worse. The only thing I can be fairly sure of is that it will be different to the one posted by philjohn.

Hey ecat of course you are right about each monitor being slightly different but assuming they are all built using the same process etc they should be quite similar so is it fair to assume that the main difference for colour accuracy comes from the graphics card?

I know that philjohn settings are based on an nvidia gpu, which gpu are you using? What calibration tool do you use?

Humm, in relation to desktop and other 2D work, when using the digital output I can think of no reason why the output of one graphics card should differ from another. That is of course so long as all the sliders and options are set such that no additional processing is performed. In this pure digital in, digital out form there is no place for any variation, the color (200,50,100) presented to the graphics card should appear at the output as (200,50,100).

In the case where the data is processed, so long as the processing is identical, the outputs will once again be the same. In the digital world, so long as everything is functioning within a well devised design envelope, there is no such thing as random variation or manufacturing tolerance. One = 1 and Zero = 0.

LCD displays are, how best to put it ? LCDs are :eek:

. 1920 x 1200 x 3 little holes. 6,912,000 little gaps each filled with liquid crystals that contort in response to 256 levels of analogue, or PWM, drive signal in order to control the light emitted from a half dozen fluorescent tubes of potentially dubious origin. And all of this, every twist, every turn, every tremor performed in full view.

There is I think a lot more scope for variation in the world of the monitor than there is in the world of the gfx card

ATI 4850 and Eye 1 Display 2

Thanks for that explanation ecat, it makes a lot of sense =D I hadn't thought about it that way until you described it.

I would be interested how your calibrated settings compare to those posted by philjohn.

Tis the one thing that completly turned me off from this HP monitor I was wondering why are so many people jumping on the Hazro/HP bandwagon and then I read a few post afterwards all of em buying calibrators !

I think for the Casual Surfer/Gamer its all about the TN panels, its a shame the HP isnt quite designed for the normal folk id hate to take a TFT out the box and have it silly bright and need a calibrating tool to adjust it !

The Ocuk 24" PVA panels are all but gone, the Hyundia suffers ghosting issues and trail effects and other issues that mirrors the Dell 2407/8 PVA issues....

The hazro/HP needs calibrating and has other issues too boot, any other 24" monitors that are even remotly worth getting?

the BenQ FP241W is a great monitor apparently, I am not sure i can handle the colours on this HP panel, for some reason it seems to be hurting my eyes when looking at text (in vista) and no matter what I change I still seem to get very saturated colours especially reds, I know this is due to the Wide Gamut but I am not sure I can get used to it. I am thinking of getting the BenQ screen and see what that's like.

Part of the reason why people calibrate the Hazro's and HP's is that they are fairly expensive monitors (I know they're not Eizo, Lacie or NEC expensive, but they're still a bit pricey) and people who spend that much on a monitor do so for several reasons, and colour accuracy is normally one of them. When you are making an investment in a screen (e.g. for work purposes) spending the extra on a calibrator is a no-brainer for colour-critical work.

You're welcome but please note all the caveats regarding identical settings for processing.

Anyway, some profiles.

1) An older profile for reference, I forget the OSD values:

http://www.i2net.me.uk/files/MonitorCalib-14-10-2008/Monitor_20-09-2008_1.icc

2) A profile I just created, brightness is very low but this is how I like it :

Brightnes: 10
Contrast : 100, I find this good for gaming though I've read a value of 80 may be more suited for day to day work.
R: 205
G: 197
B: 220

http://www.i2net.me.uk/files/MonitorCalib-14-10-2008/Monitor_14-10-2008_1.icc

3) And just for fun a very silly profile, I have no idea how it came about but you can see the blue is way out. Its useful in that you can immediately see you have the profile loaded correctly. You can then repeat whatever procedure you followed with a valid profile

http://www.i2net.me.uk/files/MonitorCalib-14-10-2008/Monitor_21-09-2008_1.icc

Looking at 1 & 2 the profiles are almost straight lines with the red, green and blue components sitting almost on top of each other. If I understand correctly, this means the monitor itself requires little compensation in order to match the recommended gamma curve. In 'Real Life' (tm), this means that color adjustment with the sliders, adjustment that suites Your Own Eyes, is valid in that it should scale correctly over the full range of available colors, at least with my monitor

Disclaimer : My color vision is not rated as anywhere near the best in the world. Also, I've only been playing with the colorimiter for a few weeks, so I honestly may be talking total garbage :eek:

Edit:
Q) Why can you not see the color aberrations in 3 ?
A) It's a screen shot and not a photograph. When you load it on your setup you will see the aberations :nod:

Just calibrated mine with an eye-one display 2, results if anyone interested:

Contrast 100
Brightness 10
RGB 226/209/230

Resulting in 6500K, 2.2 gamma and 120 cd/m2

EDIT:

I'm a noob when it comes to monitor calibration. Been playing a round a bit and seems you have to perform calibration a few times as changing something normally has secondary effects. I've found more settings that are more comfortable to (my) eye yet still result in 6500/2.2/120cd/m2:

Contrast 80
Brightness 11
RGB 248/229/253

Just been looking through some photos and amazing how they suddenly look completely natural. TBH if you spending £400+ on a monitor I reckon it's a no brainer to spend £130 on a decent calibrator...

martian_aphid · 14 Oct 2008 at 19:20

thanks for the calibration results ecat/fat dog. I would like to get a calibrator but can't justify the purchase at this moment in time, but hopefully in the future =D

Hey Fat Dog, any chance of posting your icc profile for download? Thanks.

C0mdot · 15 Oct 2008 at 20:43

thanks everyone for 19 pages on this and extra thanks to those who posted calibration settings. i look forward to going through it on friday when mine arrives from OC.

if i'm not happy with those settings, i'll probably buy an eye off ebay, calibrate, then sell it back on ebay. if i buy cheap enough i won't lose more than postage cost. good idea?

better than robbing my university, i've never even been in that department. (presumably art have one...)

Trana · 15 Oct 2008 at 21:25

I am intrested in this monitor.

I am chosing between
BenQ G2400WD
Samsung 2493HM
HP LP2475w

What worries me with the HP is the response time but especially that I have heard that text isnt sharp on this monitor. Can you who have this monitor tell me what you think about the text?

I use the monitor for webbrowsing, gaming and watching movies.

Can anyone help me with this choice.

C0mdot · 15 Oct 2008 at 21:38

i was also looking at the benq and the samsung's 26" bigger brother before i went for the HP.

the HP's input lag isn't perceptable. it is i think 1.5 frames whereas the 24" dell is perceptable at 4 frames.

go on youtube and search for 'input lag' and you will get the dell vs a CRT.

Tell me what you think when you recieve yours. I bought Samsung 2443BW two weeks ago but returned it cause it made a sound when I lowered brightness. The picture felt average as well. Dull colors and bad viewing angle. What especially irritated me was the the top was much darker than the bottom. To find a good monitor seems almost impossible. :confused:

it'll be my first TFT. my opinion is therefore rendered pretty useless.

i can take some photos of it and post them here. i have a good DSLR so you can see for yourself.

Response time isn't an issue any more, you will not notice 6ms vs 2 for a TN, but you will notice the increased viewing angles over a TN.

As for text, I've got no issues at all, here's a photo of my start menu to allay your fears.

thanx. that would be much appriciated.

That looks good, John. I hope that the negative thoughts were from overcritical persons. I am just an average guy.

Thats why I was so surprised when I recieved my 2443BW-TN. People have told me that you wouldnt think of the vieingangles unless you are a professional graphicsartist but it really buged me a lot. It was like taking 3 steps back compared to my19" CRT. Nothing was better apart from the size.

this is why i've held off getting a tft for so many years.

as for response time, yeah the HP has a great response time, it's comparable to good TNs. the ghosting is also very minimal. have a butchers at this- http://www.tftcentral.co.uk/reviews/hp_lp2475w.htm

happy days.

here are some pics just of the setting up of it.

will post some pics showing whether it's any good or not later... will have to get my tripod out to get decent pics.

took about 2 minutes to set up.
