I started my first build and now since i finished it i'm trying to connect it to a t.v, i also have a graphics board installed ( a nvidia geforce GT 740) And when im trying to connect it to my tv using the hdmi on the motherbaord nothing shows up, and so i looked online and saw that if you already installed the GPU (Which i have) that you have to use those sockets, But on the motherboard indicated led lights it says the gpu isn't detected (is that because i haven't downloaded the drivers?) And before i buy new wires i want to know which ones can i use. The motherboard had a dvi-d and hdmi, and the graphics card has a dvi-D (which i would prefer not to use) and a mini-hdmi, is it the motherboard or graphics can that i need to buy for.
