1. Why does TV have a feature to upgrade image quality to near 4K standard?
The feature to upgrade image quality to near 4K standard is a technology that enhances the quality of low-resolution input content to almost 4K resolution. For more details, please refer to the article.
The shortage of 4K content sources is one of the reasons causing users to worry and hesitate when purchasing a 4K TV. Specifically, at this time, users only have access to a few videos with 4K content such as those viewed on YouTube and through various applications (Netflix, Film+, etc.).

However, popular TV channels and video viewing applications (FPT Play, Zing TV, HDViet, etc.) do not yet support 4K.
Major TV brands have equipped their TVs with cutting-edge technologies to enhance image quality to nearly 4K standard, addressing user demands. The leading brands in this regard are LG, Sony, and Samsung.
- LG employs the 4K Upscaler technology, incorporating 6 steps to refine images (analyze, enhance, upgrade, optimize... input signals), resulting in sharp, smooth frames with vivid, lifelike colors.

- Sony competes vigorously with its 4K Reality PRO technology, utilizing multi-core processing to enhance sharpness, reduce noise, and replicate images to closely resemble 4K frames.

- Samsung UHD Upscaling is the technology featured on Samsung TVs to elevate image quality close to 4K standard. This technology operates through 4 distinct processing steps, including signal analysis, noise reduction, detailed analysis, and increasing pixel density, resulting in sharper, more detailed output signals.

However, this technology has its limitations; it improves image quality to some extent, making it sharper and clearer, but it cannot magically transform low-resolution images into 4K resolution.
