Both are 10 bit Panels but look-up-table(LUT) configurations between them are not exactly the same. Pay attention to my recent posted images and read it between the lines. The color mapping board(STDP8028) currently is not available across two Dell Precision IPS laptops. Without advanced LUT/Color Management, it would not be useful for most color critical works.

 

Update: US site had the 2760QM as of yesterday.

 

Correct, both are 10 bit panels. The HP literature says that the 10 bit card and 10 bit panel are connected by a 32 bit per pixel interface. Why the switch to saying 32 bits per pixel? 8 bits per color channel + an 8 bit alpha channel. See how well HP obscured the fact that only 8 bits of color info goes to the panel?

 

Please cite your source material or measurements. Tell me how you know it would not be suitable for color critical work. Otherwise you are just stating an opinion or making a prediction. Remember, people read these threads and make 4 digit purchase decisions. They count on what we say what we KNOW, not what we PREDICT.

 

For sake of 4 digit budget decision, both NEC P/PA solution and EIZO CG series remain the primary choice for the price to performance ratio. They offer their own developed ASIC solution with features like RGB Backlight Uniformity, 3D LUT as well as Wide Gamut to sRGB conversion < Maximum Delta-E less than 1.5>.

 

What is the max amout of ram supported at 1833Mhz ? 32gb, 16gb, 8gb?

 

Please back up your statement - "Without advanced LUT/Color Management, it would not be useful for most color critical works. ". This is not about external displays. Talk about the display on the laptop.

I already have a good understanding of how color managed workflows are built and used. I have worked within them for over a decade.

I feel that your statement "Without advanced LUT/Color Management, it would not be useful for most color critical works. " is simply your opinion. I keep asking you to provide some kind of measured proof that the HP solution with an added chip is better than the Dell software only solution. I still maintain that according to HP's own spec sheet that the data going to the panel is reduced to 8 bits. Yes, I know the HP panel is 10 bits.

Thanks for the links, but I am not a novice here. I do like to see people back up their statements with personal observation or cited measurements. So far, you have done neither. You just keep deflecting the questions.

I will have a Dell here in a week or so and will get proper measurements from a few colorimeters. I look forward to you comments on my observed results and measurements of an actual Precision with the IPS panel in real life.

 

I did not evade your questions. I already made lists of examples. And you are the one who don't understand the essence of the color calibration. Please be advised that windows would not take full advantage of wide gamut display.

Would you take initiative to download various ICC profiles for DELL U2410 (STDP6038, 14 bit Internal Processing), ASUS PA246Q (STDP6038, 14 bit Internal Processing), ASUS PA238Q (STDP8028, 10 bit Internal Processing) and made fair comparison between them ? Pay attention to their Greyscale Performance after the calibration. Freeware <DispcalGUI+Argyllcms solution> may enlighten you in multiple aspects.


STDP6028,12 bit Internal Processing, 8 bit LUT( 12 bit LUT claimed by either ASUS or DELL though)



EIZO's own developed ASIC, 16 bit Internal Processing, 14 bit LUT



NEC uPD78F1144A, 10 bit Internal Processing, 10 bit LUT



STDP8028, 10 bit Internal Processing, 8 bit LUT ( 10 bit LUT claimed by either ASUS(PA238Q) or HP(Elitebook Series) though)
