oh gaming on console?
i also saw this but they recommend samsung get 6k series above

Another bit of cleverness on the part of Samsung is careful manipulation of model number nomenclature to convince the buyer that he or she is purchasing a high end model. For example the 7 K series in Europe and USA is marketed in Australia as the 8 series but is in fact an entry level SUHD TV, albeit with a few enhancements. With a recommended retail price of around $5000 for the 65" version, that's a lot of bucks for what is essentially a mid range television - hence the appeal of the series 6 with its lower price tag and comparable ability to produce screen uniformity, blacks etc.

Well i replaced the J8000 series with this model and it compares very favourably.IMHO the quantum dot technology of the 8/9 series has no visible improvement in colour of normal programming once calibrated.For me normal programming is a 1080i feed of the foxtel sport channels and a few shows from the streaming services.I tested this model along with the 8/9 series in at HN with colour transition slides and all models have a degree of mild banding but it would be hard to pick from a normal seated distance.The quantum dot may be of benefit in HDR material but i never bought this TV for that so for me i'll call it a marketing gimmick and not worth paying extra money.You do lose the one connect box with this model which translates to 3 hdmi 2 usb on the back of the tv v 4 hdmi 4 usb 2 back 2 one connect on the 8/9 series.The one connect box is certainly a better solution for wall mounting the tv.The operating system is the same on all models and it is glorious.Fast,intuitive and a joy to use Samsung is at the cutting edge of TV operating systems in my book. One note i will make about the US reviews for the KU6300 which would seem to be the same TV they give it a bake for outputting 24P content at 60htz and introducing undefeatable judder.I tested the TV with my demo blu ray disc "Baraka" and it was output at 24p with no judder issues so that would seem to be a difference in the Australian and US.
