This is sortof a twisty topic and problem-its almost twofold, and i m looking for some input. I've brought it up and got some help in an earlier monitor thread, but i want to really try and get to the bottom of this, and am hoping for some input from the community here.
Prologue:
Back in da Day, i did all my work on a laptop that was hooked up to an old Westinghouse TN panel (i think it had 98%srgb coverage according to my sensor). These worked well together. The laptop screen was crappier (78% srgb coverage), but most of my editing happened on the Westinghouse (I\'ll call it monitor A to keep things quick)and it was well matched to the jpeg representation on my tiny camera screen, my srgb workflow (after making it print friendly) and my printing labs(bayphoto) were dishing out prints that looked to be an excellent match - tones, colors everything. I got what i shot and i was happy. Also note that, between different programs, there was no difference in showing the same file on the same screen.
Since then, I've moved on to a desktop computer, a new IPS monitor (Asus pa246 (wider gamut i think covers almost all adobergb)- lets call this monitor B) and things are a bit different. Things look pretty good still, but there is a discord and i m hoping to correct it. 1. the monitors don't look much like each other. 2. Different programs aren't handling the images in the same way (dpp looks different than say photoshop and LR).
The goal:
To be happy again. Meaning i want my primary monitor(B) to look like my tiny camera screen, look close enough to my secondary screen that i can make a comparison, and that to look like my prints. I also want all my applications to display images the same way. Incase this comes up, I currently don't intend to switch to Adobe RGB as my working color-space, because srgb is working out alright and i don't yet feel the need.
Hurdles:
It started when i noted that this picture i recently took of some trees in DPP looked brilliant green, but adobe based products made the same exact picture look a bit ..dead in comparison. This is not a RAW comparison, this is a jpeg comparison. I pulled out my camera to show me a jpeg representation and really monitor A was the only one that was really close. I started from scratch.
what i've done so far
Step 1.
Disabled windows color management, made sure gfx card wasn't trying to color manage, then calibrated both monitors (each has its own profile)using Spyder4 Elite colorimeter. Confirmed profiles in windows control panel. Light source is constant, no mixed light. Monitors are studio-matched.
STEP 2.
i generated a high quality JPEG of a well toned/colored raw image using DPP in jpeg format(JPEG because DPP doesn't see tiffs, and trying to compare raws would be silly) and copied the file twice so i could open the same file in three programs for comparison without any potential issues.
Step 3.
I opened up the copies of the same file in DigitalPhotoProfessional (DPP), ADOBE Photoshop(PS), and Lightroom (LR)at 100% (wouldn't want to see smaller representations differences showing right?). First things i noticed, PS and LR look identical. Both monitors look quite different, but i m not going to address that yet. The first problem i want to address is to make sure all three programs display the same jpeg in the same way.I noticed the jpeg looked more saturated in DPP, so i went to that first. Opened up color management in tools, set profile to the Monitor B profile, things look similar [not exactly the same mind you]on monitor B now between the three programs, but monitor A is really going out of whack displaying the blandest colors ever (also no longer consistent with the camera screen). I find i can also really go back to the pumped up color if play around with color/profile settings in PS, but haven't figured that out in LR yet. Either way, i m most concerned with getting calibrated results so my colors/tones are good and hopefully my prints correspond
What still needs to be done:
I can get a JPEG to look similar (not perfect mind you) on all three programs. I'ld ideally want to make all three look identical AND match my camera display pretty closely, but i can't seem to do that with my monitor color calibrated. On the same monitor, this should be possible for the same file with the same imbedded profile. I need advice on this, how to really make all three programs look at the same calibrated profile "the right way" for each individual monitor.
As for the second issue, Dpp doesn't really seem to care about monitor A, because the colors on it look dismal now and no longer represent the camera LCD jpeg. I am assuming that DPP is taking the single Monitor B profile and trying to apply it to A as well, but i really don't know. When i switch DPP display profile to srgb, Monitor A looks consistent with my Camera LCD, monitor B looks oversaturated in comparison, which no longer looks similar to PS and LR. At this point my goal is to get the two monitors to match a bit better and ultimately to match the camera jpeg representation, just because that gives me a simple one step surity for: A. will look like B. will look like C, and further color adjustments are easier to envision given a consistent baseline.
I feel like i should be able to do this, without an issues - but for whatever reason i can't. Could someone walk me through the steps, and maybe point out where i need to make adjustments?
Best regards,
Devinder

Things that are solved so far
1. I went ahead and read the Manual for DPP, which really helps solve one of the issues. Monitor profiles are only really true to one monitor at a time and DPP does not seem to support multiple monitor. So when i guessed that it may be applying the one monitor profile to both, I think i had that one right. Switching back between monitor profiles gives pretty faithful comparison so i m fine with staying with my monitor B for all primary photowork when it comes to DPP. Next i m going to investigate if this holds true in Adobe products. Will edit in results on this post.
2. Second bit was me being silly. Original monitor profile from DPP was looking almost perfect, but it was an older calibration. Set DPP to draw display profile from OS, which automatically took on latest Monitor calibration, which Photoshop also seems to be taking and Voila, pretty much picture perfect colors between the two programs, Just have to be careful in the case of DPP, which only successfully renders One monitor at a time (set perma to Monitor B i spose)
3. Figured out that Photoshop is pretty good at reading profiles from BOTH monitors where DPP is not. Same with Lightroom. Both A & B give satisfactory results as far as "close to each other" expecially considering difference in monitor types in the srgb space. Also found that monitor B is a bit more saturated of the two, and sadly this is further from what i see on my camera screen. I think a true test will be when i get real print results from Bayphoto... this will have to be eventually, so i get to write off that potential headache to the future. If the colors i see on paper represent Monitor B better than they do the camera screen, perhaps i ll make adjustments to THAT!If its teh other way around, I'll have to figure out how to deal with that later too, maybe by forcing "SRGB" mode on the monitor? I donno yet. Problem for another day. For today, atleast for Photoshop, i m going to consider prepress color settings and perhaps desat screen by 20% option because that looks pretty good on monitor B. Also looked at a couple monitors (less than srgb space) These comprae well to my monitor A as expected and monitor B definitely looks a tad daturated in comparison. Either at some point my calibration is off or i need to just tone it down.
Still looking for input if anyones got any...
No ideas so far eh? thats unfortunate... I'll try ask around =/
