Real fighter pilots said, that if you know where the contact is, you can see at 4-5 miles.
- DCS, 2 miles, impossible to see.
- DCS 1 miles, open formation line abreast, super difficult to see, you have to zoom a lot (not real, you should see super easily)
- Dogfight, you i´m following the tail till get some distance (no more than 2 miles) and dissappear...
In this cases, doesn´t matter what monitor you have, it should be easy for everybody to see contact.
This is a very specific scenario, forget medium distances, or trying to see contacts at 5-10 miles, SA...
