In the end, I gave up on the 10 year old September 2009 Radeon HD 5450 and bought a more modern video card, October 2016 GeForce GTX 1050, on which it all worked. For some reason, the Radeon HD 5450 does not support this most famous СVR. Apparently support of some resolution is not enough, something else is needed in the video card. It is a pity that this information was not found anywhere on the web and had to act at random. Thank you all for your help and DELL for a great monitor!
Yes, this information on different resolutions in the table is interesting, but I do not know how I can use it. I would at least localize the problem. Suppose the monitor is all right. Next is a video card connected by HDMI. So far, I have not understood whether this card can theoretically work in conjunction with such a monitor at max resolution or not. The documentation on it says that it supports 2560 x 1600 and has PCI-E 2.0 x16 interface. That is, it seems as it can, but in practice nothing comes of it. When I add custom resolution through the registry (DALNonStandardModesBCD1 hack) , then nothing changes, this item is not added to the list of resolutions. Adding through the utility "CRU.exe" also does not change anything in the list of resolutions. Maybe the problem is in the Win-7 or chip set of the motherboard. While this remains a mystery.
I've got the same problem with an MSI HD 5450 video card. The maximum resolution is 2048x1080 even on Windows 10 x64 and Linux OpenSuse Tumbleweed 2020. I will buy a basic nVidia GT 710 and hope this will work !
