In recent years, screen technology is developing stronger than ever with outstanding technologies such as: 4K, 8K, SVA panel, Quantum Dot, HDR, 144Hz fresh rate, …
Today, I invite you to learn about HDR technology, a technology that helps the screen display extremely vivid and true content.
#first. What is HDR?
HDR (High Dynamic Range) translates to Wide Contrast Range.
HDR is a technology that allows images to be displayed in which the bright and dark areas have a huge difference. That is, the dark areas will become deeper, and the areas that need light will be brighter, more prominent…. thereby helping the overall photo or video.. become more beautiful.
In other words, HDR technology was created to record digital content (images / videos) in which the subject is recorded with an ultra-wide color range along with high contrast (dynamic range), bright areas. / dark separation, clear.
Yes, looking at HDR content displayed on an HDR-enabled screen, you will immediately see, the image in front of your eyes is very realistic, vivid, colorful, the details of the dark areas are surprisingly magical – sir you!
Compared to SDR’s abuse of HUE, HDR most fully expresses all the colors and details of the subject, making the visual experience a new level.
#2. Hardware devices that meet HDR
The two most important things to experience HDR content are:
The first: The image or video file itself is recorded with HDR mode. For example, the video below (or you can find on YouTube clips shot with HDR, or blockbusters on Netflix).
Second As the display must support HDR technology, don’t worry because its current price is not much more expensive than a regular screen.
Then that’s it! Because the rest is easy to find, most hardware from 2015 onward supports HDR.

The graphic card Nvidia Geforce GTX from 950 as well as AMD Radeon R9 380 have HDR support. If you need 4K resolution, buy a monitor with G-Sync HDR comes with Nvidia series cards from 1000 and up.
For AMD cards, you should choose a monitor that supports FreeSync2 and a video card from Pro Duo or RX 590 or higher to best support 4K. And of course, the connection standard must be from HDMI 2.0 or Displayport 1.4 or later.
If you play games on Xbox or PlayStation then just missing the HDR screen is enough, because they have supported HDR for a long time!
#3. Color, Contrast and Screen Support
It can be said that HDR is the most advanced display standard at the moment, requiring the screen to support 10-bit colors (1 billion colors) compared to the original Blu-ray standard that once only supported 8-bit. (16.8 million colors).
In terms of contrast, to display HDR content well, you will need a screen with a brightness of 500 nits, even 1000+ nits, as well as a super-low black level of 1 => contrast ratio of 500:1
Note that background panels on popular LCD screens that do not support HDR, only IPS or VA.

IPS panels commonly found on iPhones are out of the question: vivid colors, good color reproduction, excellent viewing angles, etc., while VA panels are less common but have better contrast ratio as well as response speed. response time is higher.
#4. Epilogue
Okay, above is the basic information about HDR, through this article, I believe you understand what HDR is, right?
Whether or not to invest in an HDR experience is still very much down to your pocket, as well as your aesthetic requirements.
I have this advice, if you want to “play” HDR, you should buy a 50-inch 4K screen, because with a lower configuration, it is difficult to distinguish whether the content is HDR or because the screen quality is good. (OLED, Quantum Dot).
As for gamers, you should choose an HDR monitor that supports G-Sync or FreeSync technology, GPU support Ray tracing like Nvidia RTX 3000 series or AMD Radeon 6000 series then it’s over.
