Check this out, I´m so happy because thanks to the help of Hakero1 and the circuits of Eviltim and Jeroni Paul now I can put my old tvs to good use. I adjusted camera exposition but the color looks amazing first person. FYI the gtx950 can output 15khz no problem.
Only thing that worries me a bit is that the tv is 18 years old, although very little use... guess I´m gonna buy a couple more for spare now that they are being sold for almost nothing or even given away.
