On my PC there are two DVI outputs, I have been using a DVI cable with my LCD monitor in 1920x1080 without problems. I bought a DVI to HDMI cable (DVI on computer, HDMI in monitor) but the whole screen doesn't show, there is a bit missing from each side and the top and bottom.
I am using windows 7, its like my computer is displaying 1920x1080 but the monitor shows a resolution slightly lower. I have a nvidia 460SE, in the nvidia CP when I am connected through my DVI-HDMI cable, all the selectable screen resolutions disappear leaving me with no selection.
I have a nVidia 460SE running on a Samsung SyncMaster P2450H on Windows 7 64bit. I have just discovered that I am using a DVI-HDMI with more pins in the DVI part then my original DVI cable has. I believe I should have bought a DVI-D-HDMI cable instead
