The joys of the emerging range of wide gamut monitors.

I had a trusty pair of Dell Ultrasharp monitors (2410 and 2412) for
many years. Then they both died within a few months of each other. I
rushed off for their modern equivalents and found myself with a pair
of Dell UH2516D monitors.

Joy oh joy! They had a color gamut encompassing AdobeRGB and even
exceeding it. For calibration they had an internal Look Up Table (LUT)
which all the experts have been saying for years are necessary if a
monitor is to have superior color calibration capabilities. I also
found that they accept 10-bit color rather than the mundane 8-bit. As
I said "Joy oh joy!"

I walked into buying these expecting good but not expecting anything
special. And then the specs blew me out of the water.

But then I started reading, and what I found applies not just to Dell.

and
https://photographylife.com/how-to-c...amut-monitors/
or http://tinyurl.com/yb9ykg42

.... and so on.

Color calibration needs an X-Rite I1-Display Pro with software
supplied by Dell (clearly based on X-Rite software).

I have to say that this has been a problem. The monitors come with:

AdobeRGB
sRGB
Rec709
DCI-P3
Cal1
Cal2.

Only Cal1 and Cal2 can be calibrated in the monitor. At least that's
the theory, but I have so far found it impossible to calibrate the
second monitor for which both Cal1 and Cal2 stay resolutely stuck at
AdobeRGB. On the first monitor I have managed to set Cal1 to the
native full resolution of the monitor and that is a glorious sight to
behold. All the others look dull by comparison.

So far I have spent some 12 hours trying to make the second monitor
behave without any luck. Dell have been very helpful and I have spent
some 6 hours on the telephone to a lady in Malaysia. That's in
addition to the twelve hours. Dell have got to the point where they
are suggesting a clean install of Windows but there is no way I am
going to do that on my present machine. Fortunately I have my old Dell
i7 XPS Inspiron on which I can experiment.

Dell think my problems are due to something in my machine, and they
may be right. However I have read of others having similar problems
and I wonder who is wrong: Dell or Microsoft?

Just for the hell of it, here is the game I will be trying over the
next few days. Installing firmware takes about half an hour. Each
calibration takes more than 20 minutes so I hope it rains. :-(

1. Repeat attempt to calibrate DELL2Cal1 and DELL2Cal2 using existing
connections.
2. Run ‘sfc\scannow’. Repeat attempt to calibrate DELL2Cal1 and
DELL2Cal2 using existing connections.
3. Try to determine whether problem arises from a computer/system
fault by exchanging Screens so that DELL2 replaces DELL1.
4. Return DELL1 and DELL2 to their original positions. Disconnect
DELL1 and after resetting DELL2 reinstall DELL2 firmware.
5. Connect DELL2 to Inspiron i7 Dell XPS 8300 (Windows 10 Pro).
Install DUCCS and after resetting DELL2 reinstall DELL2 firmware.
Attempt to calibrate DELL2Cal1 and DELL2Cal2.
6. Execute clean reinstall of Windows 10 on Dell XPS, install DUCCS
and after resetting DELL2 reinstall DELL2 firmware. Attempt to
calibrate DELL2Cal1 and DELL2Cal2

'DUCCS" is Dell Color Calibration Software'.

Before anyone gets snarky, please be aware that short of Eizo and NEC,
Dell seems to be about the best of the bunch.

Had I set off wanting to achieve those ends at that sort of cost,
that's what I would have done too. But it all sort of fell into my lap

I think that #3: exchanging the screens for each other should be your

fine where it is. Swap the two, and see where the problem goes.

Yikes - good luck getting that one sorted out with MS, Dell, and
X-Rite. It's bad enough when there's only two blaming each other.

If you assign the same calibration to both monitors, do they look
identical? Or at least close enough? If so, I'd stop right there.

I had a trusty pair of Dell Ultrasharp monitors (2410 and 2412) for
many years. Then they both died within a few months of each other. I
rushed off for their modern equivalents and found myself with a pair
of Dell UH2516D monitors.

Joy oh joy! They had a color gamut encompassing AdobeRGB and even
exceeding it. For calibration they had an internal Look Up Table (LUT)
which all the experts have been saying for years are necessary if a
monitor is to have superior color calibration capabilities. I also
found that they accept 10-bit color rather than the mundane 8-bit. As
I said "Joy oh joy!"

I walked into buying these expecting good but not expecting anything
special. And then the specs blew me out of the water.

But then I started reading, and what I found applies not just to Dell.

... and so on.

Color calibration needs an X-Rite I1-Display Pro with software
supplied by Dell (clearly based on X-Rite software).

I have to say that this has been a problem. The monitors come with:

AdobeRGB
sRGB
Rec709
DCI-P3
Cal1
Cal2.

Only Cal1 and Cal2 can be calibrated in the monitor. At least that's
the theory, but I have so far found it impossible to calibrate the
second monitor for which both Cal1 and Cal2 stay resolutely stuck at
AdobeRGB. On the first monitor I have managed to set Cal1 to the
native full resolution of the monitor and that is a glorious sight to
behold. All the others look dull by comparison.

So far I have spent some 12 hours trying to make the second monitor
behave without any luck. Dell have been very helpful and I have spent
some 6 hours on the telephone to a lady in Malaysia. That's in
addition to the twelve hours. Dell have got to the point where they
are suggesting a clean install of Windows but there is no way I am
going to do that on my present machine. Fortunately I have my old Dell
i7 XPS Inspiron on which I can experiment.

Dell think my problems are due to something in my machine, and they
may be right. However I have read of others having similar problems
and I wonder who is wrong: Dell or Microsoft?

Just for the hell of it, here is the game I will be trying over the
next few days. Installing firmware takes about half an hour. Each
calibration takes more than 20 minutes so I hope it rains. :-(

1. Repeat attempt to calibrate DELL2Cal1 and DELL2Cal2 using existing
connections.
2. Run ‘sfc\scannow’. Repeat attempt to calibrate DELL2Cal1 and
DELL2Cal2 using existing connections.
3. Try to determine whether problem arises from a computer/system
fault by exchanging Screens so that DELL2 replaces DELL1.
4. Return DELL1 and DELL2 to their original positions. Disconnect
DELL1 and after resetting DELL2 reinstall DELL2 firmware.
5. Connect DELL2 to Inspiron i7 Dell XPS 8300 (Windows 10 Pro).
Install DUCCS and after resetting DELL2 reinstall DELL2 firmware.
Attempt to calibrate DELL2Cal1 and DELL2Cal2.
6. Execute clean reinstall of Windows 10 on Dell XPS, install DUCCS
and after resetting DELL2 reinstall DELL2 firmware. Attempt to
calibrate DELL2Cal1 and DELL2Cal2

'DUCCS" is Dell Color Calibration Software'.

Before anyone gets snarky, please be aware that short of Eizo and NEC,
Dell seems to be about the best of the bunch.



I think that #3: exchanging the screens for each other should be your
first step. Dell1 is working fine where it is, Dell2 is not working so
fine where it is. Swap the two, and see where the problem goes.

From somewhere in the Internet I have gained the impression that it is
recognised (but not by Dell) that there are problems calibrating a
second screen. It may be that the fact that I have already calibrated
DELL1 may mean that I will have problems calibrating DELL2 no matter
how I do it. Time will tell.

Is your intent to use both monitors on the same computer?

Yes.

Yikes - good luck getting that one sorted out with MS, Dell, and
X-Rite. It's bad enough when there's only two blaming each other.

If you assign the same calibration to both monitors, do they look
identical? Or at least close enough? If so, I'd stop right there.

I've now got it sorted and both monitors look the same. More to follow
tomorrow - a valuable lesson for all and sundry. Well sundry anyway.
