probably differences in biases/interests Posted by Snowmobile [Email] (#686) [Profile/Gallery] (more from Snowmobile) on Fri, 7 Nov 2014 07:46:31 In Reply to: +1 on LCD motion blur and 4k resolution., dmz789qqq, Thu, 6 Nov 2014 14:53:11 Members do not see ads below this line. - Help Keep This Site Online - Signup |
I'm not a TV guy at all, but I do appreciate good computer displays and have an ee background. I can appreciate the points made by both sides here.
If we look at computer monitors, it really does make a difference to have a fine pixel size when dealing with artificial images that are not dithered/antialiased. My laptop screen res is approx 720p and I can see pixelization in text etc but it is ok.
4k is 3840x2160
1080p is 1920x1080
720p is 1280x720
I can imagine some people with good distance vision (some are much better than 20/20) would be bothered by artifacts in computer generated images on TV's but me not so much. I guess the debate can be where to draw the line, and how one uses it makes a difference.
Going with Justin's parallel for a moment: there was often debate surrounding CD/LP and fixed vs "infinite" resolution. The reality is records do not have infinite resolution and properly generated digital recordings are dithered, so there is information at fractions of a bit. What matters is how much information is above the noise floor. Most of the reasons people like one or the other better are related to the implementation. With the right source material, a good record player sounds fantastic, and a good CD player sounds fantastic, but most people have experienced neither.
Images are similar. There should always be dither (or antialiasing for text, CG stuff etc), so we can see information below the pixel size. Failure to do so is poor implementation. Whether or not the resolution is good enough probably is more a factor of the source material and our own eyes. Probably other factors (motion, latency, colour qualities, viewing angle) become much more important than resolution, and the balance of those depends on the intended use...
