Dell Precision IPS Screen Calibration (m4600 - m6600 - m4700 - m6700)

I never tried, the Eizo is connected to my desktop.

Can you explain how you get the banding again, I didn't quite understand it... banding under which profile from which application?

 

hi
i'm going deeper on the banding subject in this other thread:
http://forum.notebookreview.com/del...sion-m6700-owners-thread-195.html#post9232600

 

I noticed on several Dell M6700 IPS that the LCD can have color temperature tint, always blue on the bottom right and red in bottom left.
I tested three of them, using my xRite I1 display pro, after calibration 120cd/m2 6500K :
1. delta 16cd/m2, 379 Kelvin
2. delta 21cd/m2 950 Kelvin
3. 16cd/m2 430 Kelvin
I know i'm not alone with this problem, but it is a pity for a so much expensive option (the IPS screen) in France (more than 700 euros !!!). A bit disapointing...
I don't know if it is the reason but Dell removed the possibility to get the IPS screen in France. Hopefully, mine is the "better" i saw.

My question is how to combine the result of the .icm file (xRite have a exe to load it when starting the session) and the software PremierColor ?
Because i saw that premier color change the brightness level (ok, so i recorded in PremierColor all the color spaces, sRGB, adobeRGB, etc... with my correct level) and unload the icm profile : while starting the session, after PremierColor is loaded, the calibration is not effective, the colors are not good. I have the re launch manually the xRite exe to load the icm profile and get the correct colors.
The only way i founded to avoid this is to uninstall PremierColor !
But sometime, it could be usefull for me to limit the gamut of the screen, so if someone know how to combine calibration and PremierColor, it would be great !
Thanks in advance...

 

regarding premier color - I also tried it and saw that it does funky stuff and messes with my calibration, so I uninstalled the software altogether.
To be honest, I think Dell has very limited knowledge of color management and thus brings out bogus software like "Premier Color" that sound good but are of little use.
I can imagine that PremierColor messes with the colorprofile in the GPU so you're better off just leaving all settings that are related to color alone (nvidia, dell,..) and just leave it to your calibration software

 

What do you guys think of thinkpad wide gamut display?

 

No comparison, it is in many other laptops aswell.

 

You cold have stopped here for all intents and purposes since that's the only software specifically caters to quality monitors, color space, etc. Nevertheless, Photoshop is also important.

It is, and you're not.

Just like distortion in music, banding is just what happens when you reach the limitation of what your monitor is capable of. Your monitor is a device capable of displaying a lot of colors (millions in fact), but it isn't capable of displaying all the colors your eyes can detect.

When it reaches its limit it "approximates" the colors (ie, shades) in between which results in what we call banding: Clear lines withing the gradient.

When a superior gradient is displayed, you should see no lines--just a smooth transition from black, to gray, and then white. With a good display system you would not be able to tell when the gradient changes--no lines.

Think of it like the difference between a ramp and a stairs: With the ramp, the inclines/declines occurs smoothly. But the stairs changes more abruptly, in "steps". Those steps are the bands which we can see as lines.

There's information between those step, but a lesser monitor misses all the subtle changes in between. When you view a radial gradient, it would show as circles within a circle. Those circles define the band, the we talk about--the region of the gradient it can't resolve.

A ten bit monitor fills in many of those gaps a lot better, but the steps are still there. They're just much smaller and a lot harder to see.

 

So sorry for this DUPLICATE POST

 

Have any of you color experts upgraded to a QHD+ screen? Can it be color calibrated? Is it good for color correction?

Looking at my signature, is it worth taking the plunge and upgrading from the M4600 w/ IPS to the M4800 w/ QHD+?

Does the QHD+ get the full color gamut and allow for calibration? I know the ultra high-res works for the Adobe suite, but how does it work for Autodesk Maya? Fuzzy? Can that simply be remedied by changing the resolution?

Does the Haswell chip and DDR5 GPU make it no contest?

 

Yes and no.

No! These are pretty to look at displays. Not highly accurate, 10 bit displays for creative artist. They are not for you.

So many questions. Same as above.

Don't be fooled by glitzy advertising and the like. If color accuracy is what you're after then consider only IPS panels. For this use, everything else is inferior.
