Hi Guys, I've looked through the thread and there is some useful info, which I think helps me, looking to perhaps take advantage of the Costco cheap deal, but concerned about a couple of things, reviews don't rate the speakers, I'm upgrading from a sony 50W829b which is known to have reviewed very very well back in the day and the speakers are fine, think the XF9005 sound would be much worse ? and the other thing has been much talked about, but I'm still not 100% sure what it means, full HDMI Ports only 2 and 3, I understand the bandwidth 60hz thing only on these 2 ports, but are we saying that SKY Q and a Fire-stick 4K, there is no advantage in putting these in Ports 2 and 3 because they wont be reaching these frame rates anyway ? 2 or 3 should be for my my PS4 Pro or PC ? But ports 1 and 4 I don't lose out on HDR or Dolby Vision or anything else? Am I upstanding this correctly ? Thanks in advance, any quick advice would be great, deal time running out I would imagine,
