it's a trade-off.
there are several image type provided by dcs, tv color, ir, tv bw derived from ir, new flir
not sure you still remember the bug that sometimes the whole monitor was covered by big black plate (not only jf17 had this issue, i remember hornet had/has it too)?
this was caused by using tv color (although post processed to bw), and this affect the game experience
so we have to use tv bw derived from ir which looks quite similar to new flir.
