Yes
I've just ordered a new ips led monitor. I'm under the impression that monitors need calibrating every 6 months or so as gamma and colour change due to the fluorescent backlight. Is this advice not relevant to led backlight as there light doesn't change as far as I'm aware.
 
I calibrate every 2 weeks and before any major image manipulation session.

Any change in ambient light levels requires it as well.

Also remember monitor needs to have been on for at least 30 minutes before calibrating.
 
Never had to calibrate my dell monitor, so sold a colormunki as it was pointless having it.
Suppose it depends on how much quality your after and if your doing your own printing.
With older type monitors yes there could well be a case made for calibration but these IPS monitors are far better.

What I have done is make sure the computer (windows7 professional) is that its all set up for photos in colour management.

Also it depends on how good the graphics card is as well in the computer not just relying on calibration.

Bit like having a Rolls car body with a Travant engine.

The light output from LED's change just like anything else so calibration is as relevant to them as it is to IPS/LCD/CRT/whatever. Monitor calibration isn't only intended to correct for changes in the screen itself but also in the ambient light that you are viewing in as that has an effect on the colour, saturation and contrast of what you see on the screen. This is why most (if not all) of the good calibrators have that feature.
 
I calibrated (Colormunki) my Dell LED monitor when I got it and the before and after examples showed a marked change in saturation.

Better at what? If the calibration is wrong they're no different than anything else. Do you really beieve that IPS monitors don't vary from one to the next and they all come out of the factory exactly alike?

So, you think Windows knows how your monitor is performing as compared to the nominal standard specification? How does it compensate for the ambient light your viewing in? Don't believe this changes what you see on screen .. put your monitor in the airing cupboard and see how much difference there is compared to your living room.

Using a calibration device takes account of all the variables in your viewing system - both hardware and software - as it compares the actual screen brightness and colour against a "standard". There are no assumptions made about performances of anything being "nominal".

I'm not sure I understand this analogy unless your suggesting W7 is a Rolls Royce and the Colormunki an old Eastern European car. Personally, I'd use that analogy the other way round.

Oh, and it's Trabant, BTW :)

Please stop nit picking my and other members postings.

Your own observations would be more acceptable in your own posting not criticising others. Respect other members views and thought and their own experiences. One persons findings may not the same as yours but that is no reason to do what you are doing.

I think he's right to comment because you keep repeating information which is incorrect.

ALL monitors need calibration, without it, your PC will be displaying something which is non-standard. It may be close, but that will only be by luck rather than judgement.

Whoever has told you that you don't need to calibrate is plain wrong. A number of people have told you this in the past, but you keep repeating it as if those who tell you you are wrong don't know what they are on about. They do.

The only time you get a comment is when you give blatantly incorrect information and refuse to accept that you may well be in the wrong.
 
Yeah I certainly agree with Andy (arad85) and Steve (Bristolian) here. Realspeed - you should probably avoid posting in threads about monitors, your advice is unhelpful and your information is inaccurate. Although having an uncalibrated monitor may be fine for you (and me atm for that matter), it is not for many others. They DO need calibrating. My two IPS screens have VERY different colours. I should calibrate them really, but not willing to spend the money on the device needed just yet with my finances as they are.

I'm not going to respond to this ... it's been covered by others ... except to say, don't take it personally ... it's certainly not intended that way :)
 
To all
I only post as I find not what I think. Calibration of monitors is old hat, you don't even see products like Colormunki being advertise very much because modern IPS screens don't need it.

If you have to keep calibrating then there is something wrong either with your computer set up-graphics cards or monitors.

So to start with lets take your computer, if you have an old computer then you can't expect to have the best output, I would suggest upgrading the processor to start with and Intel core i7 is what you need and only cost £250. Next a good graphics card, you can't get a good picture by relying on the motherboard grsphics so get something like an MSI GTX560Ti Twin Frozen one, it will only set you back £170. My IPS monitor was £170 so the total cost just for those components is only around £600. If you wanted the whole setup unbuilt like mine expect to pay about £1500 or more or have it built which would cost I expect about with vat £2000/2500 at least including operating system and good speakers (needed for video reproduction sound).

So lets start with a decent computer and reasonable monitor anything less isn't worth talking about. Shop bought prebuilt computers are rubbish so don't even put them in the same class, you have to build your own dedicated computer if you want to do photographic work which is what mine is

I am not going to back down on this subject as I know my own equipment which doesn't need calibration.

Ok to be fair I would agree that maybe in most cases members are working with far less/cheap and incapable computers/monitors and no doubt do need calibration.



My front screen totally unedited and my uncalibrated monitor. Yes I know its not level but just wanted to post EXACTLY as take. And that is after it has been through Image Shack to be able to post on here

Oh dear.

Yes, because the processor obviously has an impact on colour production.

Either you are a troll or just plain... No wait, that might get me in trouble.

OP, go to an old peoples care home, speak to the oldest person there, ask them for their advice, then if you want to get worse advice, go for a grasshopper, then maybe a brick wall, before listening to realspeed.

You really should do you know, because you're making yourself look very silly! :lol:

Just about everything in this post is wrong.
 
You'd have thought, with 5 people telling him he is wrong and 0 people agreeing with him, that he'd consider that he might be a bit wrong :lol:

Yup - uncalibrated. Looks completely wrong - the colours are too saturated.
 
And as I have posted before. I have the same GFX card and iirc IPS monitor in a custom built editing PC which needs calibrating regularly to keep it accurate. Also costing a 4 figure sum.

I agree with the others that image you posted is way over saturated.

Calibration old hat, total testicles I'm afraid.
