4K offers four times the number of pixels than a standard Full HD (1080p) TV. HD TVs come with a resolution of 1920x1080, while 4K displays provide a resolution of 3840×2160. As a result, 4K TVs boast many more pixels compared to HD displays.

Q: Is a 4K TV Really Worth It?

4K TVs boast more pixels and have an advantage when it comes to colors. 4K TVs offer more features like HDR and a clear difference in color, sharpness, and clarity compared to a Full HD TV.

Q: Are 4K Smart TVs Repairable?

Like other internet-connected gadgets, Smart TVs do occasionally have software problems. Mostly, these can be resolved by updating the television's firmware or operating system. If you have trouble with a particular app, updating or reinstalling it often fixes the problem.

However, hardware issues are more challenging. There are many TV repair companies, but it's always worth checking with the manufacturer first to see if your device is still under warranty or can be fixed directly.
