At 99% certain it's your fault. Color managed applications are meant to be used with a ICC profile assigned to monitor that matches it. You cannot use sRGB or AdobeRGB preset with "UP2716D.icm" profile (native gamut)... so if you do not calibrate and profile your monitor (actually a widegamut is useless without it) you should use sRGB or AdobeRGB ICC profile for monitor while in that menu presets. All of this should be done before starting Photoshop.

P2715Q is a sRGB monitor, not full ISO Coated coverage

UP2716D is a widegamut monitor, almost full AdobeRGB & ISO Coated. It is best suited for photo, editing, print... and such things.
As a general rule, a widegamut monitor without an i1DisplayPro colorimeter is a waste of your money, so you need 200 euro for that device. If no budget, get UP2516D... if this is out of budget too, do not buy a widegamut.
In order to simulate CYMK profiles like IsoCoated (or some printer+paper ICM profiles) with that Dell you'll need a color managed enviroment like Adobe CC suite, using that programs softproof capalibilies.

If you need to simulate a CMYK profile without color managed enviroment (why???) you'll need a NEC PA242W (cheapest option) with SV2+Multiprofiler software, and use LUT3D emulation capabilities of that NEC hard+soft solution.

If you cannot get 2560x1440 over HDMI, your laptop is the culprit at 90% certain. Ask Dell as you did, IDNK max res. over HDMI with Inspiron 3537.

As usual, my thanks to yumichan for the assistance. The Inspiron 15-3537 HDMI is version 1.4a. So the highest resolution you will get at 60Hz is 2048x1152.

AFAIK 1.4a can drive DCI 4k @24p, 4k @30Hz and 2560x1600(or lower resolution) @60Hz (like older U3014 & U2713H)

Thank you. I will rethink it.

Yumichan, OK, I will calibrate that monitor if needed, probably leave to professional instead of buying colorimeter. And yes, I am working in color managed software.

But I am confused: that monitor is advertised as factory calibrated. Well, if that calibration isn't good enough and I have to calibrate again, what's purpose of factory calibration?

And I am sorry, I can't see on that wikipedia link that 1.4a can drive 2560x1600, a just see it for 1.3. For 1.4 is written 4096×2160p/24 Hz, which doesn't mean too much for me, I don't know how to calculate which resolution would be supported at 60 Hz.

If it's correct what Chris said, that I can get 2048x1152 on 60 Hz, I have to rant. I bought my Inspiron 3537 1,5 year ago and it wasn't cheap. First surprise was that it haven't DisplayPort and if I can't get 2560x1440 resolution, which I think is standard these days, what does it mean? That I have to buy new computer every year to keep up? It's insane.

Calibration should be done several times in a year, 6 or more times because white & grey balance drifts.
Factory calibration gives you emulated gamut (smaller than native) for sRGB and AdobeRGB gamuts and their gammas, these two OSD modes, no more. It is done at 50% brightness and as ALL calibrations on ALL monitors... it drifts (WP + grey balance). Factory calibration is "meant" to D65 white (which won't be accurate) for sRGB and AdobeRGB so if D50 white is needed... you do not have it.

No i1DisplayPro => No widegamut. Get a U2715H/U2515H instead (sRGB 2560x1440)

HDMI is backwards compatible in resolutions, it would be useless otherwise.

The HDMI out on the Latitude E7240 (released 9/13) and the XPS 15-9550 (released 10/15) have the same 1.4a 2048x1152 60Hz limitation. The sales site for the Inspiron 15-3537 did state 1.4. But you are correct in that it did not state the maximum resolutions =

Hi,

I bought UP2716D and yes, it works on 2560x1440 resolution, thank you both very much!

Now I have other question: Colors in Adobe RGB and sRGB presets are not accurate at all, especially sRGB. When I look in Adobe Photoshop or other Adobe software, where RGB color settings are set to sRGB, red color looks orange-brownish, not close to clear red. In Standard color preset colors look much more accurate, maybe little oversaturated.

Without calibration, I expected that colors might not be 100% accurate, but I didn't expect it can be so wrong.

So I checked graphic card drivers, they are up to date. I tried to reset monitor to factory settings, not helping.

Can I do something else to make it work? Is this normal or monitor's issue?

Yep, my fault, you helped a lot, thank you so much!

I added Adobe RGB and sRGB profiles in Windows Color Management, set sRGB as default and now colors are looking accurate in Adobe programs. They are looking same in Windows File Explorer and little weird in Chrome, I am not sure is it color managed or not, there is lot of different infos on web about it.

I found old thread when you answered similar questions about U2413 monitor. I will buy colorimeter as soon as I can, but in meantime, maybe you have some suggestions about brightness/contrast settings, like you had for U2413? I need sRGB for my photos and sometimes Adobe RGB for graphic design.

Here is that old thread I found:

Without an i1DisplayPro: sRGB profile is for sRGB preset, AdobeRGB profile for AdobeRGB preset and "UP2716D.icm" is for "standard" (or even "color temperature") preset.
You must set one of these as default profile before starting a color managed program.

Windows image viewer is color managed (matrix profiles only, I think), "Photos" on W10 is not color managed (bad), but you can restore old Windows image viewer (good).
Thumbnails in Windows Explorer are not color managed (bad), WIndows desktop is not color managed (very good, you can simulate other screens with a good monitor with HW calibration and LUT3D emulation)

Firefox has color managed and could be configured to do full color management to sRGB for images or colors without profiles (good), all other browsers had no support (or very limited) for color management. So for Windows/Linux users with a widegamut monitor my advice is to use Firefox, always (OSX users should use on Safari, Firefox can have issues with faulty color management bundled with OSX... Windows is much better, no desktop color management).

Custom configurations of a monitor are for THAT monitor.

Thanks again!

I configured Firefox to have color management and i see big difference between Firefox and other browsers when I am in AdobeRGB color space. When I am in sRGB, everything looks pretty much same as in Photoshop: Windows explorer and Photos and all web browsers. Maybe little duller/darker in web browsers, but I am not even sure anymore, too much staring in colors these days. :)

So, if everything looks same for me in sRGB, I guess that my photos on web should look similar on other people's screens and all web-browsers, is that right?
