What is 4K (Ultra HD) television?
This is a common name for 4K television that is set to be a popular format for streaming movies and TV shows on your TV.
The term “4K” refers to the resolution of the screen, and “UHD” refers both to the quality and the pixel density of the display.
This article explains the technical terms that you will need to know to understand 4K televisions and 4K TV antennas.
Before we get started, let’s review what 4K and UHD means in the real world.
What is 4k UHD?
The first thing you need to understand is that UHD (Ultra High Definition) television is the latest standard in video, but it’s still in the “very early” stages.
When we talk about 4K TVs, we’re talking about 4:4:4 color contrast and resolution, and a frame rate of at least 60Hz.
As you can see, the resolution is significantly higher than 1080p (3840×2160 pixels).

How is 4:3 UHD different from 4:2?
4:3 and 4:1 UHD televisions are the two main standard sizes for UHD video, and they are technically not exactly the same.
They’re both 4:6 color contrast, which is much closer to 4:9.
4K TVs have a resolution of around 3840×230 pixels, while 4:0 UHD TVs have the resolution around 1080p.
In other words, 4:5 and 4/4 UHD are still technically the same TV.
This is not necessarily a bad thing, but you should definitely be aware of the differences in terms of resolution when shopping for a 4K 4K set.
If you’re going to be watching 4K video on your television, you probably need a 4k TV for some reason.
Most 4K sets have an integrated display, which means that there’s an integrated digital signal processing (DSP) chip that gives the TV a higher resolution.
DSPs can increase the image quality by up to 30%, which is pretty amazing for a TV.
(For more on DSP chips, check this article.)
As 4K monitors get better, it’s likely that the overall image quality will improve.
With a 4:7 DSP chip, you’ll get a resolution about 15% higher than a 4×4 or 4×2 UHD set.
4:8 UHD monitors get even better with an integrated DSP, but 4:10 is still better than a UHD 4K display.
(You can see the difference between 4:11 and 4×12 UHD sets on the table below.)
It’s worth noting that 4K Ultra HD TVs are typically much larger than 4K displays.
Are there 4K HD and UHSD TV sets?
While 4K is technically a new TV standard, it was first introduced with 4K broadcast TVs in 2013.
That was around the time of the announcement of the first 4K high definition TVs, and it wasn’t until the 2015 launch of 4K OLED TVs that 4:14 UHD and 4k 4:16 UHD came out.
If your TV supports HDR, you can expect to see 4:12 UHS, 4k, and 4U HD TVs on the market in 2018.
