Question

two color profiles in two different monitors

I have an old Cintiq without hdr and a new monitor that does. I work my illustrations on the Cintiq and like to have the same document on the other secondary monitor to see the overall work. But of course, if I turn on hdr on the new monitor I see it very desaturated. And if I take it off a tad saturated (which I would have to calibrate). Changing the Photoshop color profile does not correct the problem, because if I activate the Window's calibrated hdr profile of the new monitor, on the Cintiq it shows me the colors logically oversaturated.

Is there a way for photoshop to show on each monitor a color profile? So I would not have to be removing and putting the hdr on the new monitor. Since I want to have it active for other purposes.

Another option would be to buy a Cintiq with hdr... I know... But it would not be a very cheap solution...

Sorry for my roosty English BTW

I just managed to see it the same as on the Cintiq by putting in the window that is on the new monitor with HDR the test color (CTRL+Y) "RGB monitor".

I admit I don't quite understand why. But I will test on different monitors and devices to see if it looks the same as on my Cintiq.

I hope this is helpful to someone who was in my situation.

Proofing to Monitor RGB disables all color management. It nulls out and cancels out the monitor profile. It sends the RGB numbers in the file directly to screen, without any correction for the monitor's characteristics.

 

So just be aware that what you see on your monitor is not what it will look like on any other monitor.

 

Also, I would think an 8 bit jpeg, extended to a much higher dynamic range, will display with considerable banding and posterization. A jpeg will already have a certain amount of inherent banding under normal circumstances. But maybe that's not a problem here.

 

As for the HDR aspect I have some reading to do. I don't have any HDR displays myself. It seems to work fine by itself, but I don't know if it's possible to combine with an SDR display. Someone else will have to answer that.

Photoshop does use separate monitor profiles for multiple monitors, and this has always been fully supported in Windows.

 

When you run a calibrator to profile your monitors, you do it separately for each monitor.

 

However, I don't have any personal experience with HDR monitors. It's possible this throws a wrench into the machinery, I don't know. One of the things I need to find out.

 

But the question is, what is the final use of the file? HDR is for screen only, and obviously needs to be seen on an HDR monitor to make sense. If it's for print, HDR is wrong on every level. Then you need to mimic the dynamic range of ink on paper.

I'm working on an illustrations for a game on a web. No print. I would like to get the highest quality for people viewing this website with HDR and non-HDR monitors.
I work in sRGB IEC61966-2.1 (8bpc). When I export a jpg of the work, on the monitor with HDR I see it fine, but the phoshop window on that monitor looks desaturated the illustration. ¿?
