I don't know much about TVs either but Dolby Vision appears to just be their name for HDR, which Samsung have. 3D? Meh. But definitely buy another model if you want it.
PS I love how all these websites showing how great HDR is have "Simulated for illustrative purposes" plastered all over them. What that translates into is the end effect on you TV viewing is quite possibly almost negligible.
Shows as new.
I was referring to the 65" model, but think I confused my discount vouchers (Bing Lee is 20% off not the GG) so 7% smaller (65") but only 15% less cost ($2500). Bing Lee Don't seem to have the 65" model but the 60" model is half the price of the JB HiFi 70" - not bad.
I would also lean towards the Modulator. In TV end terms no other end box - no extra receivers required. The negative is no IR capabilities, which you may or may not require.
But if you do want IR in the future. I would suggest looking for one with IR Return so you can upgrade in future to use remotes in other rooms. Maybe look at the Resilink 1603. https://dpanda.com.au/digital-modulators/548-resi-linx-hd-1603.html. The negative with the IR is to use it you need to add their hub & IR targets, which starts to mount up in price. But at least you have it for future.
Sorry haven't had much to do with HDMI over network. Very interesting!!
