4K Television Set/ Ultra HD Television/3d Television

Its the latest among all the techie person or the electronic gadget lovers, big screen tv with a huge price tag on top of it – yeah am talking about the “New hero” in town the 4K TV’s and the UHD TV’s. I thought I will explain you clearly the differences and explain you what the big buzz is all about.


4K Ultra HD TVs (also known as UHD TVs) deliver four times as much detail as 1080p Full HD — that’s eight million pixels compared to two million pixels.

What that means in terms of potential image clarity is more fine detail, greater texture and an almost photographic emulsion of smoothness. But this is just for starters. Prior to a roll-out of TV services, broadcasters are working out what else they can upgrade under the 4K banner.

Two types of resolution of 4K are
1. Consumer Standard:3840 x 2160 (at a 16:9, or 1.78:1 aspect ratio)
2. Industry standard: 4096 x 2160 (at a 1.9:1 aspect ratio)

What is UHD tv?

There are no big differenes between 4K and UHD TV as the UHD TV are the derivatives of 4K. The Consumer standard as I have mentioned above is the UHD TV. So the name given for the Consumer standard Version of 4K is the UHD TV.

Why do they come only in Big Sizes

Screen sizes are likely to stabilize at 55-inches and upwards. That’s because as the screen size shrinks the advantage of having such a pixel dense display starts to diminish. There’s also an irrefutable relationship between screen resolution and viewing distances. While seating will vary from home to home, generally speaking a large 4K TV will provide an upgrade for a smaller 1080p screen. However, the 4K resolution will ultimately be about more than just definition.

High frame rate UHD broadcasting could have an even greater impact than resolution when services begin — and the benefits of HFR are not restricted to larger screen sizes. When this second generation 4K UHD breaks cover, expect high-frame rate 4K TVs to drop further down the size scale.

Thank you for your valuable time and pls do give me feedbacks about my Technology Blog. See you all next time with some interesting topic.
