4k TVs are worth it now!

Recommended Posts

Although they didn't make sense in the past, 4K TVs aren't stupid anymore. Here’s why.

Most TV’s that were sold until not too recently were 1080p TVs. Which have a resolution of 1920x1080. A 4k TV has 4 times the number of pixels as a 1080p model does.
 

From the beginning resolution increase is never enough, by itself, to justify the price of a brand new Ultra HD TV.


There were many reasons why 4k was just a selling point until recently.

Let’s go over some of them.

The demise of high-end 1080p TVs

LCD TVs to look their best need a couple key features. A high refresh rate and local dimming.

 

Local dimming improves contrast ratios, contrast ratios are the difference between black and white. How dark the black is, vs how light the white is. This can make an image have more depth and realism if the contrast ratio is higher vs smaller. If you want to learn a bit more you can check out this topic: 

To put it as simply as possible, high-dynamic range (HDR) expands the range in which your TV creates light. Bright parts of the image can get much brighter, so the image seems to have more "depth" and realism. Wide color gamut , for its part, expands the range of colors your TV can create, deeper reds, greens, blues and everything in between.

These two improvements, available only on high-end 4K TVs for now, can do more to improve picture quality than mere resolution ever could. Of course, those TVs also require HDR and wide-color TV shows and movies to take full advantage.

The bottom line is resolution is not enough, but thanks to the TV scientists out there, we not have an amazing improvement to picture quality that is included with the resolution upgrade that makes it all the worthwhile, HDR, and WCG!

But, don’t be fooled by thinking that the resolution upgrade alone was ever enough for the standard viewing experience. Please make sure to check out my other TV tech videos here if you want to learn more!
