Part 2 The results continues:
Normal safety isolation transformer isolates the hot and neutral. The ground must not be isolated according to electrical regulations.
This creates a major safety hazard! Do not try it! Some (even some balanced ones ) audio power conditioners have ground lift switches. This is the only safe way to do it, that I know of. But they are very very expensive.
Why did I buy a balanced isolation transformer and not a normal safety isolation transformer?
3 reasons:
-Balanced power improves power factor, which is one aspect of power quality.
-Center tapper earth (0V), reference ground. Very important for sensitive equipment like computers, which need a clean and quiet ground.
-Removes grounding currents
This unit does also have electrostatic shield for transients spike protection (elevators, air conditioners, a refrigerators, etc.)
Power factor improvement is only achieved with balanced power. The power factor Indicates the degree that current and voltage are in phase to each other. 1 to 1 is the optimum. You can google power factor improvement if you find better solutions, but this is the one I found, it's the easiest and cheapest way to implement.
If you want to try balanced isolation transformers, don't just blindly go and buy balanced isolation transformers. First you need to make sure you have electrical input lag. Most of the time, the cause of the input lag is the hardware, the internet or the program itself.
Tests to verify your input lag:
1. Offline too (Ethernet cable out), on desktop.
2. Outlet. Different outlet?
3. Time varying input lag? If yes, then high likely cause is electricity.
4. Test with resistive load device. like incandescent lightning or clothing iron/heating element. You can plug incandescent lightning to power strip.
Do not plug clothing iron/heating element to power strip. It might overload the power strip (max 10 amps). Add it to the same circuit.
If you get improvement with this, then you most likely the input lag is caused by electricity.

Resistive load
When you add incandescent lightning or clothing iron/heating element to the circuit, it improves power factor.
Conclusion:
The balanced isolation transformer did fix my problems. No more vibration or hum. Noise (EMI) is still high in wires, though. I will most likely change the EMI/RFI filter. It can be changed to a better one if desired, just a new part. But overall I am satisfied with the product.
I still use compensating resistive load (incandescent lamp 60 W) on power strip after the balanced power supply.
I did a test with a game to see if balanced power improves performance of computer, while gaming.
Test games were Elden Ring and Elite Dangerous. I don't play fps games.
I noticed that my computer was a bit quieter. I didn't notice any picture improvements.
I wish I could verify if this works for electrical input lag but I can't because I don't have it yet.
I can only give advice on what I think could solve the electrical input lag.
