Without fully understanding what you are saying and guessing that you have (or wanting to) a 720P resolution monitor displaying that resolution through HDMI/DVI connection! It is compatible and should not create any issues.
first of all, thank you rolli59 for responding to my quest. what I would like you to note that my monitor's display resolution is 1360x768, I just bought a HDMI to DVI cable connector (HDMI from my graphics PCI-E card to DVI at my samsung PC monitor with a description in the packaging of 1080p which to my limited understanding speaks of resolution display. so my question is with the HDMI-DVI cable with 1080p resolution against my monitor's maximum resolution, would it not cause any compatibility problem in the future?. thanks for being patient with me.
