...apparently you sit closer to a 4K/UHD TV monitor than a 1080/HD TV monitor.
Unless it’s a bigger one.
Unless its two times bigger or more. ...Well that's based on my extrapolation of data from this graph<https://i.rtings.com/images/optimal-viewing-distance-television-graph-size.png> on this webpage<https://www.rtings.com/tv/reviews/by-size/size-to-distance-relationship>... If you watch a 30 inch 1080/HD TV at 1.2 meters, then its worthwhile watching a 30 inch 4K/TV at a distance of between 0.6m and 1.2m in order to receive the benefit of 4K/HD over 1080/HD. Alternatively, fixed at 1.2m from the screen, then watching 4K TV's in the range from 30 inch through to a 60 inch is worthwhile compared to watching a 30 inch 1080/HD TV at 1.2m Thus, as a rough guide, it is not until the diagonal screen size at least doubles with a 4K TV, that you should consider sitting further from the screen than you would with a 1080/HD TV. Also see the chart that they provide on optimal distance. I've reproduced it below: Screen Optimal Distance Size 1080p 4k 25" 0.98 m 0.46 m 30" 1.16 m 0.52 m 35" 1.35 m 0.61 m 40" 1.56 m 0.71 m 45" 1.74 m 0.80 m 50" 1.93 m 0.89 m 55" 2.14 m 0.98 m 60" 2.32 m 1.16 m 65" 2.50 m 1.25 m 70" 2.72 m 1.35 m cheers, Ian.
