HDR Capability Checker

Acquiring the knowledge of how this tool works.

You always wondered whether your screen would be able to actually show these rich colors and rich contrasts that the contemporary content creators would like to see through. And that is what this HDR Capability Checker can allow you to discover. I would like to show you a tour on how it works and the implications of all those technical terms to your view.

The Hdr Question and Why You Have to Learn about It?

The term HDR can be discussed as the abbreviation of High Dynamic Range, and this is the revolution in the perception of visual content. Help yourself to think of what one may see in a picture and what the other may see in reality. The traditional screens (using what is known as SDR or Standard Dynamic Range) can only show a limited range of that which our eyes will perceive. The HDR displays are much nearer to the reality because they show brighter whites, darker blacks and more variety in between.

Whenever you watch an HDR film or even play an HDR game you are not just seeing additional pixels, but additional depth, more of the shadows and highlights that truly jump out without rendering it in a washed-out manner. The only thing is that you need both your hardware (your screen) and your software (your browser) in order to have the advantage.

The HDR Detection of How This Tool Works.

This checker utilizes some smart tricks to find out what can be done with your system. It is not just a guessing game but you are actually querying your browser/hardware what it can technically do. It is what is happening in the back scene:

1. Display Hardware Detection

To begin with, we can not accept the reality that you have a monitor or a screen that literally supports HDR. We do so using such magic as CSS media queries that enable websites to ask your browser questions concerning the display. When the tool queries regarding dynamic-range: high it is, in fact, querying the browser whether this screen can support HDR. This is communicated to your display hardware by your browser.

The same thing applies to the color test. The range of colors that the display can display is the technical name of color gamut. Think of it as a palette of a painter, some palettes contain only simple colors (that is sRGB) whilst others contain much more vivid and different colors (that is Display P3 or Rec. 2020). Reviews your palette, on which you are working.

2. Screen Resolution and pixel Information.

It is a comparatively easy part. It determines the number of pixels of your display and the density in which it carries. Another interesting value is the pixel ratio - it tells whether a person has a high-DPI display (e.g., Retina display). The thing is that ratio 2.0 means that there will be twice the number of pixels in every direction compared to a normal display, and everything will be sharper and more detailed.

The number of bits used to denote colors is referred to as pixel depth. The more bits one has, the more is the number of colors. A 24-bit display can show almost 16.7 million colors and a 30-bit display can show more than a billion colors (usually found on the HDR display). It is what causes a gradient that is smooth and one that has color bands that can be identified.

3. Browser applications and Software.

You have half the war in the possession of an HDR-capable hardware. The browser should be able to provide that equipment with HDR content. It is at this point that interest enters.

Canvas HDR tries to find out whether your browser can write graphics in HDR in Canvas API using the Display P3 color space. This is significant to the web based graphics applications and games which would like to utilize wider colors.

WebGL HDR deals with graphics of 3D. The most recent version is WebGL 2.0 that enables an in-depth display of 3D in your browser which is needed in games and in engaging visualisations that can desire an HDR display.

CSS color color definition CSS color can be used to define colors in wider color spaces and interpreted and rendered by your browser as a stylesheet, as well. It is the manner in which web designers can declare such hyper-vibrant colors that go beyond the ordinary RGB.

The HDR Video is to check whether the browser can decode video formats of HDR. We just check the support of HEVC (H.265) codec that is the one that HDR10 content usually uses. This is to inform you that you may watch HDR videos in the browser or not.

4. Color Advanced Format Detection.

Display P3 This is the wide-color gamut of Apple standard, but has become a standard of high-end displays as well. It also exhibits up to 25 percent more colors than the standard sRGB, especially colors in the reds and the greens. Once this seems to be endorsed, everything extra-vivid you have seen on the movies and in high quality professionally edited photographs can be on your screen.

HDR10 is the most popular HDR format of video content. It is an open standard which is compatible with majority of TVs and monitors with HDR. It means that in the case of the availability of this it is possible to decode and provide the HDR10 video content, i.e. Netflix HDR, YouTube HDR, and HDR gaming.

Dolby vision is a high-quality HDR and is more developed than HDR10 because of its dynamic metadata (it alters HDR settings per scene to scene). It has low percentages of support and also offers it with more advanced displays and devices.

5. Graphics and Hardware Acceleration.

We also check your graphics card information (GPU) through WebGL. This tells us the producer of the graphics card in your computer and what model that is. To be more precise, we ensure the presence or absence of hardware acceleration. Hardware acceleration Hardware acceleration is the phenomenon that the graphics card of your computer is doing the heavy work of graphics rendering, and that is what allows you to play HDR video, as well as being able to play games smoothly. In cases where it is disabled or where you are rendering software then you might not get the best experience possible with HDR even in cases where your hardware theoretically supports it.

Visual Test Patterns What Does the Visual Test Patterns Show?

Not only are the boxes on top colored but they are actual tests. The grayscale gradient determines how good a screen is with regard to being able to alternate between pure state black and pure white. Proper HDR display should be able to exhibit smooth transitions that do not show banding.

The color boxes are comparison of the standard sRGB colors to show P3 wide gamut colors. P3 displays are to be far more bright and full-bodied in comparison with the corresponding sRGB boxes. Upon looking so similar, then most likely you can only show in sRGB.

Why Does All This Matter?

Knowing the HDR of your system will give you the impression of the content you can actually produce in the quality you can. Being a content creator, you must know whether you see the colors in the right way or not. Suppose you are purchasing a new monitor, this tool is capable of testing the information that is stated in the spec sheet. And in case you just need an optimal video experience of streaming services or games, it is better to know that you have the HDR support and, thus, your settings are supposed to be modified.

Absence of the HDR support does not depict that your screen is bad, it merely suggests that it has been produced with other intentions. Most jobs can be managed by use of normal displays. Nevertheless, as a photography or video editing lover, a gamer, or just want the most immersive viewing experience, it becomes quite clear what the difference between an HDR and a regular is.

The Technical Side The Way we do It.

This tool is in all web standards as it is interested in the technical implementation. CSS Media Query Level 5 is applied to identify the hardware, Canvas API with color space parameters, WebGL to retrieve the information on the GPU, and the ability of the HTML5 Video element to verify the codecs. It is all in your computer (not a single bit of information is exchanged). The device simply asks your web browser to provide it with information regarding your computer and your web browser will get it via your operating system and display drivers.

It is an excellent example of how web technologies have developed in our contemporary world to give the websites all the knowledge they know you can and can not do with your system and hence the best experience that impresses the most out of what fits your specific hardware.
