Okay so this might be a stupid question, but I honestly have no idea when it comes to displays or any of that. The monitor I have is an acer V233H, and it says on the box "1080 HD", yet doesnt have a hdmi port. So, I went out and bought a DVI to HDMI adapter. Before this, I was using vga. I cant tell a difference in the picture quality though. Is there a difference in the qualities of the two?
