    So if a had a tv which was 20” would it have the same total amount of pixels as a 60” tv? So would the 20” tv would have a higher pixel density of pixels then the 60”? (The size 60” and 20” are just made up. I’m not sure if they are actually sizes used.)

    There is a difference between Ultra HD and 4K. Ultra HD is 3840x2160 whereas true 4K is 4096x2160

  • @frizzyacademic

    Isn't 4k/UHD four times HD (720 x 1280)? Rather than Full HD? I've seen Sony dipicting it that way.

    • @oleast
      @oleast Před 9 lety +1

      FHD = 1920 * 1080, UHD("4K") = 3840 * 2160. UHD is has twice the pixels on the vertical and the horizontal axis as FHD -> 1920 * 2 = 3840, 1080 * 2 = 2160. That also means that 4 * FHD = UHD, 4 * 1920 * 1080 = 3840 * 2160.

    • @Leuel48Fan

      HD (720p) x 4 = 2K (1440p)
      Full HD (1080p) x 4 = 4K (2160p)

    • @Julianna.Domina
      @Julianna.Domina Před 9 lety

      4K is 2560*1440, while full HD is 1920*1080p, and 720 standard HD is 1280*720p. Quad HD or QHD on smartphones and tablets is 4 times 720p and 2 times 1080p, earning it the title of 2k.

    • @oleast
      @oleast Před 9 lety +1

      New American Fishkeeper 4K is NOT 2560*1440! True 4K is 4096*2160, but people also refer to 3840*2160 as 4K. qHD = 1440p 4*HD = 4(1280*720). qHD =! 4K...

      Only technical or semantic: DCI 4K (the original 4K) is 4096×2160 while UHD 4K (QFHD or UHDTV-1) is 3840×2160.

    I don't think it's worth buying a 4k screen at least not for a few years. When gaming consoles are capable of handling 4k resolution games, and tv programs are recorded in 4k.

    4K is the amount of pixel that can fit on one screen
    Basically simple equation: 1080px4=

    • @oleast
      @oleast Před 9 lety +1

      No, it's not. It's the number of pixels on the axis of the screen with the most pixels on it... A UHD screen (not really 4K; but close) has 8294400 pixels (3840 * 2160 = 8294400).

    This is so annoying! If someone says 4K, you won't know what resolution they're exactly talking about!

    4096x2160 =Cinematic standard, Apple's definition of 4K and some others.

      Ok, 3840 x 2160 is going to win out and be referred to as 4K/UHD interchangeably because its 16:9. The other one has a weird non-standard aspect ratio, so no need to confuse consumers.

      @musicalhistory4392 Před 9 lety

      Poundtho-1440p is almost 50% higher then 1080, or almost double the actual resolution. But its main goal is to be 4 times 720p or basic hd, but 5k displays are already edging the market(IMac and Dell), so to point out that these displays are really insane. 2k is only useful on a computer to be able to see 1080p content and share a good portion of screen. Just as 5k is coming to be, on a phone you don't see it, and it's all for Specs!!!
