So I recently purchased a Sony 4K TV and I cannot figure out why my Video Card will only allow me to display 1920 x 1080. I know the card can go higher as I used to use a Dell 30 Inch monitor and could display the highest resolution on it.
My video card is a Radeon HD7800 card with 2 GB of RAM. I am using a HDMI 1.4 cable through my Onkyo receiver which also has up-scale capabilities but yet the maximum resolution I am getting on the TV is only 1080p.
Any suggestions would be great appreciated.
