Connecting a PC to my Samsung TV

I am trying to connect my computer to my Samsung UE32EH5000K TV.

It has a HDMI/DVI input port which is where the manual suggests to connect the PC to.

I am current using a vga cable with a vga - hdmi adapter to connect it to the TV.

When I follow the instructions regarding connections and editing the name of the source it still says that there is no connection.

Anyone know a way to solve this issue?

I haven't tried using a dvi-hdmi cable from my computer yet, but I thought it should still work with a vga + adapter, anyone know if this is the case?
