U3219Q, input color format

Thank you! We have received the required details. We will work towards a resolution. In the meantime, you may also receive assistance or suggestions from the community members.

RGB for all.

If whitepoints do not match IN THE CENTER OF SCREEN, match them using RGB gain controls & brightness under Custom Color OSD mode, visually or with a colorimeter (i1displaypro family recommended using DisplayCAL & proper spectral correction fir that display backlight)

Hi

Thanks for the response. I checked the color calibration report for all 3 monitors and they are all different as far as color uniformity is concerned. Are they supposed to be different. ? I am seeing that all 3 monitors look different with same identical settings. Please see attached pic. Could it be related to color uniformity? I tried different preset settings but cant get them look like same. 2 of monitors (Left and Right) look more yellowish than the middle one? I have tried them to connect to different systems but the result is same. Can some define the problem and how would I know which one is faulty if they all look different for the same settings.

Sorry for the delay in response.

We have received the emails.

As asked previously, can you share the invoice of the monitor so that we can have it checked.

Hi 

I have sent you the invoice on email with subject : Service tag:

* Yes, that is correct. Even when the same model, no two monitor panels will look exactly like the other. Every monitor panel is unique and the factory default for each one is based on specific manufacturer guidelines, not a cross comparison of other same model monitors. The only way to get a closer match is to purchase monitor calibration hardware colorimeter and software. User yumichan is the monitor calibration pro. Just read through his post by clicking his name.

can you give up some more details?

Hi

The calibration report says , '...Precise and Consistent Onscreen color for EVERY dell u3219q monitors'. So I would expect that the all monitors would display same colors with identical settings. Plus as I said I can't get preset modes to match the same display for all 3 monitors.

As far as calibration hardware is concerned why should the user but another piece of software/hardware after spent so much money on the monitors so that all can look/display same color content?? Why can't dell ensure that before delivering the monitors.

Please help, I need to all 3 monitors to looks/display same color for identical settings. 

Regards.

Hi 

Please let me know what details you want.

Uniformity looks the same on 3 monitors. No visible color shift across screen on each one.

What you see is different whitepoint on each one. Use RGB gains in custom mode to match them, visually or with a measurement device.

Using center as reference and if photo is accurate (which may be not even if you have a superb $5000 DSLR because metameric failure too long to explain here),
-left seems low on brightness, raise it a bit till match. Minor whitepoint tweaks with RGB gains in OSD.
-right whitepoint looks off in green, lower it a little using RGB gains, raise brightness a little to match, then minor RGB tweak again.

"The calibration report says , '...Precise and Consistent Onscreen color for EVERY dell u3219q monitors'. So I would expect that the all monitors would display same colors with identical settings. Plus as I said I can't get preset modes to match the same display for all 3 monitors."

To what target? to what requirements? mean? median? With default settings of after calibration (*)?
That's the game they play... so you cannot argue if it is not written. Your only possible way to complain is return for retund, those 3 REALLY are within specs beause the reason I wrote as questions. In the end is user/customer who does not know or understand the meaning of what is wrote.
(*)any monitor with reasonably good color uniformity across the screen could match your quoting... but not all of them with factory settings to "what you want" /"to your desired calibration target"

"As far as calibration hardware is concerned why should the user but another piece of software/hardware after spent so much money on the monitors so that all can look/display same color content?? Why can't dell ensure that before delivering the monitors."

'Cause THERE IS NO UNIVERSAL calibration target... although you may argue that "sRGB gamut, D65 & 2.2 gamma" are a "common target". Again read what I wrote as question: what target does Dell aim to? Is it written? Now you understand. Same applies to other non premium manufacturers.

"Precise and Consistent Onscreen color for EVERY dell u3219q monitors" IS TRUE as long as for MY desired target (which can be D50 for softproofing) I can set monitor to THAT desired target using OSD buttons or HW calibration id available (for UP series).
I mean, they were no lying, it's just that users do not understand the precise meaning of those words "in color management"/"calibration".

Please help, I need to all 3 monitors to looks/display same color for identical settings.

Do as instructed, use RGB gains in custom color mode to match their white point "visually" or with a measurement device. Other from that WP mismatch it looks from uploaded photo that monitors have no issue (color uniformity etc)

Hi ,

Thanks for your detailed response.

Its not that I want Dell to deliver monitors as 'I want or as I desired '.  But I would like if the monitors are set to same 'preset' mode then all should look like same. I guess that's what preset means. I am ok if I get monitors with all set at different 'custom mode' with different RGB values then I know all will look different. But if all have same RGB and set to 'standard' mode then I guess I can't say what 'standard' preset mode means. I have tried changing the values and I can get left and right monitors to look pretty same but I can't make the middle one look like other two or make other two look like middle. 

I will need an expert to tell me what values of RGB will make all look like same. Need help please.

Hi 

Please see attached pic and can you please tell what settings I can do to make the left one look like the right one (which looks more bright). I have tried multiple RGB gain settings and can not get it look like same. I am no expert in monitor color calibration so any help is much appreciated.

Its not that I want Dell to deliver monitors as 'I want or as I desired '. But I would like if the monitors are set to same 'preset' mode then all should look like same.

I understood but:

I guess that's what preset means.

Not really if target for each preset is not an objective set of values with small tolerances.
What calibration target is standard mode? "Usually" it means native white, 2.2 or sRGB like gamma and native R G & B coordinates. That sentence, that target defined AS IS has different results for all panels.
As long as display after such factory calibration validates as a fairly linear display with no grey neutrality errors on "native gamut, native white, 2.2 gamma"... calibration report will run OK.
Do you understand? Marketing and loose defined "targets".

Or for example let's say that there is a "sRGB preset". That's a more objectively defined target. It should have D65 white and R,G&B coordinates should be sRGB ones with SOME tolerance (error).
If tolerance is high, each two devices may differ between THEM but be under tolerance WITH REFERENCE.
For example, imagine a road coast to coast. Put a city in the middle of it. That is like our white reference D65. Marketing guys says that you can have a house somewhere 5miles away from that point. But some houses will be 5miles away to East and some others 5miles away towards West. They are UNDER TOLERANCE (less than 5miles) but actual distance between them is 10miles.
Do you understand the trick? Tolerance errors should be very small to get wat you want because inter-device values can go up to 2x tolerance.

In the case of "standard" preset, reference is not even the same point in map. Each monitor has its own, "native" white, panel "as is" with its maximum brightness and constrast.
They are loosely defined calibration targets that most consumers do not understand.

I am ok if I get monitors with all set at different 'custom mode' with different RGB values then I know all will look different.

It's the opposite, if out of the box they do not match on "Custom color" preset with R=G=B=100 (native white) there must be a RGB gain combination for each one that makes them match with some tolerance (under some error).

"I will need an expert to tell me what values of RGB will make all look like same. Need help please."

For an accurate match you'll need a colorimeter... or you can try by eye. I wrote before some hints to match WHITE from your 1st capture. Thats what you can get with RGB gains in custm color mode.
Your 2nd capture "may" imply ("may", because IDNK the settings) that there is a grey/gamma mismatch (but maybe it's just white mismatch and I cannot know for a photo). Grey/gamma is difficult to correct without colorimeter but you may try your OS "visual calibration". Depending on your GPU you may get banding on gradients after that.

Colorimeter => i1DisplayPro or if you renounce HW calibration in future monitors and speed, i1Display Studio will be accurate too.
IDNK U3219Q's backlight, you need to know it bafore measuring with a colorimeter.
If it is just a plain sRGB display colorimeter need to be corrected with Whiet LED backlight.
If it is some of these new P3 monitors... it is more complicated because ther eare several backklights that allow it. But it seems that Dell uses W-LED PFS phosphor backlight. These corrections are available in i1Profiler (bundled with i1displaypro) or even better DisplayCAL (free).

Go to Custom color mode, make sure RGB=100 for all of them. Try to keep 1 value at 100 (R or B or G) and play around till you get a match. You may need to raise or lower brightness on some monitor at the same time
