All TVs have a native resolution so that every broadcast or format they receive will be displayed in their native resolutions and will only be able to display video at their respective native resolutions and no higher. This basically means that a TV set is better at displaying HD broadcasts that are in its native resolution. The LG 43" Class (42.5" Diagonal) 4K UHD Smart LED TV w/ webOS 2.0, Model # 43UF6400 has a native resolution of 2160p which is four times as many pixels as 1080p TVs. Major network signals are broadcast in high definition at either 720p or 1080i and your cable/satellite box can be set to output a specific resolution. So when you watch HD content (720p, 1080i and 1080p are all considered HD) on the LG 43UF6400, it uses a process called upconverting (or upscaling) to convert incoming sources to fit its 4K screen. Think of upscaling as a stopgap measure in the absence of true 4K players and content, just as with DVD players that upscaled their content to 1080P, upscaling noticeably reduces the appearance of blockiness and jagged edges, and while a 1080p upscaled image may look good on a 4K TV, it will not look anywhere near as sharp and detailed as 4K content nor as good as 1080p content on a 1080p screen...^IFV
Sorry, there was a problem. Please try again later.Upscaling will improve the picture, but not necessarily to 4K quality. Here's a link with details: http://hometheater.about.com/od/hometheaterglossary/g/upscalingdef.htm
Sorry, there was a problem. Please try again later.No, companies are standard broadcasting in only 720, or 1090p right now, they are up and coming with 4k in the couple years but it does not upscale 1080p hd into 4k. If your watching a 1080p video on this 4k tv, its going to be 1080p. You have to be watching 4k content to watch it in 4k. If you want to watch 4k content i suggest the roku 4 that is 4k based and comes with a hdmi 2.0 cable. I wouldn't upgrade your hdmi cables because you have to reason to because 4k is not available on cable providers tv boxes.
Sorry, there was a problem. Please try again later.It tries to compensate for the low quality by using a processor in the TV that scales the quality to 4k. Of course it wont look as good as true 4k content but I still think hd content on this TV looks better than on a regular hd TV.
Sorry, there was a problem. Please try again later.If you buy an antenna you're going to get about 35 channels only a few of which are HD like channel 4, 6 and 12 (local). You will need to have cable or AT&T or other provider to get HD content or better yet, do Netflix and Hulu with a $30 antenna. I just bought a 4K, 1080 P smart TV and only get local programs on the one TV that just has an antenna. On the TVs that are connected to AT&T, I noticed motion much more w 4K and the picture is good with HD but any content without HD is lacking.
