Evga geforce GTX 780 3gb sc best card

Product Name: Evga geforce GTX 780 3gb sc best card
This is the card used on my living room pc , can play light gaming csgo at 160-250 fps , never tried other games(guess cs 1.6 doesn't even count as light best gaming, which has 300+fps) The problem for this card, is that miracast not working , this happens when I upgraded it months ago , saw some one mention that miracast is dead or something, but it's very useful when I use the pc to cast movie on my tv, ironically the new video card I installed also not working with miracast , anyway sell it since no use for it.
