U2724DE, Feature Request, Multipoint grayscale adjustments
Hello,
I would love to see Dell implement an option in the monitors OSD to also have a multipoint grayscale adjustments for the RGB channels, for us the coloring nerds.
I have a U2724DE and it's been doing great, but on the other hand I'm also using CalMAN to perform screen calibration services, and when I measure my screen Dell at home, I can make it look "alright" but nowhere near perfect especially if this screen only has a 2 point calibration for the RGB(Gain and Offset) alongside some very basic chroma of only Hue and Saturation.
Well, I did the best as I could, but I can still see errors along the multipoint measurements, for example a big spike from 20 to 40% on the grayscale, and then another spike at 80 to 100% on the grayscale with a DeltaE of >5 which is noticeable.
So my suggestion is for a extra feature via a firmware update to also include the multipoint adjustments in the monitors OSD menus.
Example:
Include a new option in the "Color Presets" menu called "ISF", or "Expert" or something similar(whatever it is) that will actually allow the end user to also have control over each individual picture settings.

This is not a "new firmware feature"... it's a fully writable 1DLUT of N points (likely 256 x 3channels), an optional API for 3rd party integration and (firmware) a M point RGB correction that firmware will interpolate to populate the N point LUT.
Other price segment than current Ultrasharp line...
Giving its current price "coloring nerds" will buy an i1d3 colorimeter and fix this in GPU (1D o 3DLUT) and of course do not use calman to test factory calibration.

Hi, and thanks for your reply, highlighting some details.
However, there are some important reasons why coloring nerds would also like to have these features available from the OSD, and prefer to make a hardware calibration instead, which is why I think these should be available options from the monitors OSD, and not having to rely on a software correction using some 3rd party tools, etc. which is always an option if nothing else works, but it's not an optimal one for certain.
Usually this comes to the fact that these monitors are usually connected to more then one systems, running different OSs, so some of them may not necessarily support the CalMAN software suit(MacOS, Linux) and the only available solution to have a uniform calibration across all connected systems is to have the screen hardware calibrated, from either the OSD of the monitor(manually) or from via an API connection to the 1/3DLUT table of the monitor on a hardware level, and make the adjustments there, without having to rely on software corrections via .icc profiles.
I have the full set of CalMAN hardware, and software, and given the limitations from the monitor itself, I can only do a 2 point grayscale(Gain and Offset) on the "custom color" setting which is nowhere near the desired level of accuracy that can be achieved if only there were more options available on the OSD itself, and to my understanding, the OSD is something that is done on a firmware level, but please correct me if I'm wrong.
