Any data to support this statement?
Why don't online UPS fix the input lag problem?
Because at the output they give out not a pure sine wave, but with steps (teeth).

When viewed normally, the sine wave appears to be perfect, but when magnified, we see steps.

Computer switching power supplies are very fond of modified sinosoids.
One solution to the problem is to use a toroidal balanced transformer. It smoothes the steps in the sine wave and eliminates electrical noise.
It it was harmonic distortion then a regular UPS disconnected from outlet would solve the problem, but it doesn’t.
No, it's not. When the UPS is running on battery power, the sine wave is greatly distorted, it becomes similar to a meander. This is because the battery is slowly discharging electrical current.
The UPS works best when plugged into an outlet. You can go to any audio forum and see for yourself. People specifically remove batteries so that the sinusoid is not distorted.
In addition, we found that the input lag is caused not only by the distortion of the sinusoid, but also by other factors.
Electrical noise (sine wave distortion) is 50% input lag.
A little later, we will test our theory and say what the reason really is.
Ya for audio. It filters the RFI/EMI out, same with power conditioner. If input lag was caused by that then power conditioner etc would work.
If it was sine wave distortion then a online ups would fix it too.
The problem is much more complex then that.

Does a toroidal balanced transformer solve this whole problem?

The program shows a mouse delay of 160ms.

Where does it show 160ms delay? Am I blind?

I think he mistaken timestamp with latency column. 160ms would be insanely bad.

Yeah, actually his results are pretty good, most lower than 10ms if im reading it right.

Yes, that's right. I did not understand this program and already wrote a post.
But this program does not accurately display mouse delay. Sometimes with the same values in the program, the mouse behaves differently.
I will test again in the future.
