Question

RE: Planning to Purchase a 4k tv - need opinions

Sep 14, 2016 6:16PM PDT

Considering several models of 55" or 65" 4k TV's (Sony & Samsung primarily). Basic question - should i consider a higher end 4k tv with a smaller screen size (i.e. 55") or a larger 4k tv (i.e. 65") which may not have as good of specs. We typically sit around 10-12' from the tv?

The chart at https://carltonbale.com/does-4k-resolution-matter/

At 15 feet it's not so much the 4K at play but the color and contrast at play.

Here's the chart and then you need to really look for HDR. Samsung is pushing their Quantum Dot over OLED but if I were to go on spec alone, and still would need to see each model to check it out for deep blacks like we had in plasma I think Sony may get the nod. Besides Samsung's Smart TV gaffes are legend.

Here's that chart:

To get the full benefit of 4k, you need to sit closer to the TV than the diagonal measure of the screen. (Few people actually do this, I imagine.)

With a 65" TV and a 10-12' viewing distance, the resolution of a 4k TV should not be distinguishable from a HD (1080) TV, unless your eye can resolve much finer than 1 arc minute (0.3 milliradians).

HDR/WCG (high dynamic range/wide color gamut) would work at any range. I doubt that the entry level HDR sets do it well (they have 8 bit panels, vs. 10 bit for high-end), and they don't do WCG at all.

If you watch a lot of sports, you'll need to consider whether the TV is good with fast motion.

I'm not trying to be a wise guy. I think that your question is a little naïve, and that you'll have to do more study to have much hope of getting what you'd like. Which will depend on what you use the TV for. (My primary viewing is movies, from BD or UHD BD disks.)

Thanks for your comments. I was comparing a Sony x850d in 55" to the Sony x750d with a 65" screen. Primary watch streaming movies, sports and general tv. Just trying to decide which of these may work best, or if there are some 60" models is should consider. Budget is up to $1,400.

Sony XBR-X750D-Series 65

The Sony XBR-X750D-Series 65 seems to be HDR10 ready. I'd stop here as what is HDR10 is where it's at.

The 55 inch from what I read does not have HDR10.
