How to distinguish true and false 4K TV, I believe everyone wants to know
4K TVs are currently the most popular and sought-after products in the television market. When shopping for a new TV, many consumers automatically go for 4K models. However, not all so-called 4K TVs are genuine. Some only support 4K playback but lack true 4K resolution, which is often referred to as "pseudo 4K." With so many options on the market, it's important to understand the difference between real and fake 4K TVs.
The term "4K" refers to a video resolution of 3840x2160 pixels, containing approximately 8.3 million effective pixels. This is four times the resolution of Full HD (1080P), offering much sharper images and more detailed color transitions. Compared to 2K (1080P), 4K can display up to 80% more color depth, making visuals more realistic and lifelike. It also provides a wider dynamic range and finer image details, resulting in a more natural and immersive viewing experience.
So how can you tell if a TV is truly 4K or just a "pseudo 4K"? One way is to test it with H.265-encoded video files. If the TV doesn't support 4K playback in this format, it's likely not a real 4K TV. Another indicator is the pixel arrangement: genuine 4K screens use an RGBW layout, while standard TVs use RGB. You can check the product specifications or promotional materials for this detail.
You can also use professional tools like the TV Screen Tester app, which includes a 4K resolution test. By analyzing test patterns, you can determine whether the TV actually supports 4K resolution. Additionally, the China Household Electrical Appliances Association recommends using a magnifying glass to inspect the screen. Fake 4K TVs may show blurred colors or visible white lines when viewed up close.
It’s also important to note that owning a 4K TV alone isn’t enough to enjoy 4K content. You need a 4K source, a device that supports 4K decoding (such as a Set Top Box), and sufficient internet bandwidth. Currently, 4K content is still limited. Most TV stations don’t broadcast in 4K, and 4K Blu-ray discs are rare. While some online platforms offer 4K videos, they’re mostly clips or demos rather than full-length content.
However, the situation is changing. As 4K technology matures, more companies are investing in 4K content. For example, Guangdong Power Grid has launched a 4K TV network application plan and is working on establishing a dedicated 4K ultra high-definition channel. It's expected that the first official 4K TV channel will launch before the end of the year.
If you're considering buying a 4K TV, it's definitely worth it—especially as 4K content becomes more widely available.
