...you wouldn't have to worry about dealing with that particular issue, since the 120 & 240Hz specs only apply to LCD or LED-LCD HDTVs.
Don't let them up-sell you on expensive monster cables. You would get by just fine with entry level cables that handle the HDMI 1.4 spec just fine. Many folks here order from Monoprice, Blujeanscable & Amazon (Amazon basics) with great results that are definitely on par with the highly marketed Monster brand (etc.).
i understand the benefit of going high end on the HZ, theoretically. But what I am seeing is that no source can deliver over 60 HZ and certainly not 240HZ. And while most H+DMI cables can handle 240 HZ and beyond, the box stores try to up sell you on high end cables as if you have to be consistent with cable lable (HZ rating) and TV (HZ rating). What is the truth?
