FIFA/EA FC Input Lag Questions

[mimaradam]

Hi everyone,

I have a question about input lag for FIFA/EA FC on PS5.

As you may know ea fc is locked at 60fps on PS5. I am using an lg cx oled which its input lag is measured at 13.6ms for native@60Hz at game mode. I also have an ips monitor for work purposes which is asus proart pa278qv and it shows as 8.6ms for native@60Hz. I tried some matches both on the same console, same network etc and found the gameplay exactly the same in terms of latency even if there is a 5ms gap. So based on this I have some questions;
1. Is 5ms not a margin to be observed?
2. Dell Alienware AW2523HF, which supposed to be one of the lowest input lag as 0.5ms. But this monitor is measured at 8.4ms for native@60Hz. So this means Asus pro art and this one have both similar input lags for EA FC even if the Dell is advertised as a gaming monitor? So shifting from Asus to Dell will have zero impact in terms of input lag? Or are there some other parameters that the general responsive feel of Dell will be better?
3. Does monitor size affect the input lag? as most of the monitors are 24" for fifa esports
4. Are IPS, TN and OLED panels have different responsive feel while playing even if their input lag measurements are exactly the same?
5. If a monitor is 2k native, Lowering its resolution to 1080p on PS5 give less input lag, or it stays the same?
6. And finally if 5ms difference (between LG cx tv and a dell alienware gaming monitor) cannot be observed, isn't the input lag for tvs over monitors a bit exaggerating (for 60fps)?
So i believe these 0.5ms input lag for the gaming monitors are only important for the PC users then. So this makes me think why the FIFA esports players on PSS5 are using these kind of gaming monitors if there is no difference with the other monitors like Asus pro art i mentioned above, or the tvs on game mode?
