Can you suggest me "stop-by-step" what I've to do in my case?
just like you're explaining it to a child...
infinite thanks
The detailed resolution you showed me has totals 4400x2250 and pixel clock 237.37 MHz:
237370000 / 4400 / 2250 = 23.97676... Hz
Your screenshot shows 23.97797 Hz:
23.97676... - 23.97797 = -0.0012023...
That's how much it's off by. So you need:
23.97676... - 0.0012023... = 23.9755653... Hz
If you put 23.9755653 Hz into the pixel clock calculator, it will give you the pixel clock and horizontal/vertical totals needed to get close to that refresh rate:

Both CRU and the NVIDIA control panel have horizontal/vertical totals that you can enter manually. CRU also lets you type in the pixel clock instead of the refresh rate, while the NVIDIA control panel only lets you type in the refresh rate.
The easiest thing to try first would be to simply change the custom resolution refresh rate to 23.975 Hz, since it's off by around 0.001 Hz.
If you want to tweak it further, try entering the values given by the pixel clock calculator. Keep in mind the projector might not be able to handle certain horizontal/vertical total combinations, so you might want to test with the NVIDIA control panel first.
If I put the 560 horizontal blanking in the pixel clock calculator, I get something close that should work:
237.78 MHz 4400 x 2254 @ 23.975558603 Hz (-0.000006697 Hz)
Simply change the custom resolution totals to 4400x2254 and the pixel clock to 237.78 MHz, and it should be closer to what you want. Keep in mind that measurements are not exact either because Windows is not a real-time operating system, but this should reduce the number of frame repeats.
Here's another guide that goes into detail:
