I applied the patch for AMD/ATI Pixel Clock Patcher all values current state "already patched", value Low-resolution limit current state "found".

That GPU is too old. HDMI with that GPU is limited to 165 MHz pixel clock, which is not enough for 2560x1080 @ 60 Hz. AMD didn't officially support higher pixel clocks with HDMI until the 7000-series, and the patcher can only increase the HDMI limit for 5000-series and newer GPUs. You can try adding a detailed resolution for 2560x1080 @ 50 Hz instead of 60 Hz if the monitor allows lower refresh rates. If not, you should really get a newer video card, even if it's a cheap low-end one.

I had followed you advice and added 2560x1080 @ 54 Hz in detailed resolutions (CRU 1.4.1) which is under 165 MHz pixel clock after this I saw it in display resolution settings and applied it. It work pretty well, now I am write it to you in 2560x1080 @ 54 Hz on ATI Radeon 3000 onboard. The monitor flicker free, so I do not think the lower refresh rate make any harm for my eyes.

I failed to add any higher values than 165 Mhz. The monitor can work 2560x1080 @ 75 Hz with some video cards and I think with a pixel clock patcher it should done the best (not found it for now).

For general users it almost impossible to make it work, but to upgrade their PCs even if they are satisfied with the current perfomence of their PCs. It was such a headache, I never thought before manufactures use some connections standards to limit the monitors compitability. I always thought only the GPU speed will affect a maximum resolution.

For now I am happy that with your help I done it

Are you know how to initially power on my PC with 2560x1080 @ 54 Hz? For now it 1920*1080 in bios and after windows 10 loaded it becomes 2560x1080 @ 54 Hz.
