How do you know it? I went on an online website and bought a 1m hdmi cable, but it doesn't specify if it's 1.3. or 1.4 because it came in a plastic wrap. i think 1 m is perfect and if longer than that it can't fit my desk. How to I know? Is there a program where I can check? I dont want to get dvi or display port becasue my LG monitor only can have freesync thorough HDMI
