Why you can trust Tom's Hardware
I was initially bummed that the 42M2N89 cannot be calibrated, but once I measured it, I came away impressed. This is a seriously accurate monitor, as in professional level.
Grayscale and Gamma Tracking
Our grayscale and gamma tests use Calman calibration software from Portrait Displays. We describe our grayscale and gamma tests in detail here.
It is safe to say that OLED panels in general are very color accurate. None of the monitors require calibration and only benefit slightly, if at all, from adjustment. The 42M2N89 has no visible grayscale errors with all dE values under two. Three is the generally accepted level where issues become visible. Lower values are considered visually perfect. I noted two slight aberrations in gamma, slightly light shadows and slightly dark highlights. But these errors are also visually acceptable. This is excellent performance. Because I could not calibrate the 42M2N89, there is no post-calibration test result.
If you switch on the sRGB gamut, it shrinks the color space correctly and the grayscale is unchanged. But gamma becomes more skewed with a visibly lighter shadow area in the 10 and 20% steps. This is a visible error that cannot be corrected. Color-wise, sRGB mode is fine but its gamma issues mean a slightly less punchy image.
Comparisons
Since the 42M2N89 can’t be calibrated, I’ve posted the 1.34dE grayscale error result to both the before and after charts. None of the monitors here have visible grayscale errors, so this comparison is essentially a wash. They all look the same to the naked eye.
The 42M2N89 is only off the 2.2 gamma standard by 0.45%, which translates to a 2.19 actual value. The PG42UQ matches that result with the other monitors slightly more off-target. All have a tight range of values so again; the gamma comparison is largely a wash. They all look the same to the naked eye.
Color Gamut Accuracy
Our color gamut and volume testing use Portrait Displays’ Calman software. For details on our color gamut testing and volume calculations, click here.
The 42M2N89 absolutely slayed my color gamut accuracy tests with near-perfect results. In the DCI-P3 realm, which corresponds to the Standard picture mode, only the 60 and 80% red targets aren’t perfect. None of the points are off by more than 2dE, which is astounding performance for any monitor. The 42M2N89 is better than many of the professional screens I’ve tested.
In sRGB mode, red, magenta and blue are a tad under-saturated, but the errors are barely visible. The overall average is still well below 3dE, which is excellent.
Comparisons
Like the grayscale results, all the OLEDs are supremely accurate. The 42M2N89 takes the crown in the gamut test but a visual comparison of all monitors would reveal no differences. It truly doesn’t get better than this.
Philips claims 95% coverage of DCI-P3 for the 42M2N89 and it delivers. Like nearly all wide-gamut monitors, the deficiency, however small, is in the green primary. But the error here is so minute that you won’t see it in actual content. All the displays here are fit for color-critical applications. The 42M2N89’s sRGB mode is a bit weak with just under 90% coverage so I would likely choose a different monitor if I needed an accurate sRGB or Rec.709 gamut mode.

Beat me to it. I don't know why / how monitor manufacturers continue to ask for obscene prices when there are same/better products for cheaper.oofdragon said:It's a TV And on that note you can find the LG 42 OLED 120Hz around $700
The 48" LG can be had for $500 less too -
Greg7579 Christian, I need your help. I am a Medium Format (GFX) photographer and have enjoyed editing and viewing my own extremely high-resolution files on 32 inch 4K professional IPS monitors (various ASUS pro monitors over the years). I am about to build a top-end gaming PC, but I do not game. I just want a fully loaded extremely top-end PC because I just do, and also because Adobe Photoshop and Lightroom use a lot of AI masking and features now, so I will be running a 4090 GPU and the best ram and CPU that can be had. Now the monitor....Reply
I almost ordered an ASUS mini-LED at 3-5 grand this past year but held off. I've followed the OLED invasion that you wrote about and know you love OLED. I have an OLED 80 inch TV in fact.
But I'm about to order the Dell 6K you reviewed, and I know you talked about the drawbacks of IPS and the HDR performance of that Dell IPS monitor. But 6K is 6 K.... And I'll be viewing and editing thousands of those huge GFX raw files. Plus, the Dell 6K IPS has double the PPI of this Phillips OLED monitor.
I am so tempted by this OLED invasion. and this monitor. I know my images will look stunning on it.
But 6k is 6k.... And the Dell PPI is way better....
Plus, I won't be able to get back 4 or 5 feet from that 42-inch monitor. I will be at normal desktop viewing distance.
I have heard some productivity guys say not to go with OLED unless you are a gamer. They talked about fonts and how the screen looks with windows 11 and all the Microsoft and Adobe programs having certain issues. One prominent tech guy said to not even consider OLED for Windows productivity work.
Is this monitor OK for productivity and for my photography? I don't care about not being able to calibrate it. The color specs are awesome.
So, what do you think, Sir.... Should I get the Dell 32 inch IPS 6K or this (or one of these) 42 inch OLED?
I don't care about the cost in this case - 1400 vs 3500. I care, but it is not an issue in this case. The Dell is twice as much, but it is 6K....
Would you be willing to tell me which way to go in my case? Should I get that 42 inch OLED for what I do (not game). -

6k is 6k ? get 8K oled .... 32 inch 8K resolution OLED monitors are coming this year.Greg7579 said:Christian, I need your help.

I don't think 8K OLED desktop monitors are coming this year. I might be wrong about that. Hope I am. But how is OLED for productivity? Photoshop? Lightroom? Windows? MS Office? The web? I'm not a gamer but will have the powerful PC.newtechldtech said:6k is 6k ? get 8K oled .... 32 inch 8K resolution OLED monitors are coming this year. -

with high brightness monitors it does not matter anymore being matt or glossy ... -
