A:Answer It comes with an HDMI cable and a DisplayPort cable. However, if you want to max out the monitor and use it to its fullest potential, plan on buying your own short, certified cables. With mine I couldn't get more than 120Hz out of the DisplayPort cable that came with the monitor. Once I bought a DisplayPort 2.1 certified cable I was able to do the 240Hz. Personally for a monitor that has a regular list price of about $2,500 I think Samsung should have supplied high-quality certified cables with the unit.
