4K TVs are becoming the new norm with the Chinese OEMs launching affordable 4K Televisions every few months. From being a cutting edge technology a few years ago, 4K TVs are now mainstream. However, with 4K TVs, we have 4K TV not upscaling issues as well.

Just because you have a 4K TV doesn’t mean everything you watch on TV is 4K. To experience true 4K you need to have 4K content as well. 4K content is still a rarity because most of the videos are still in Full HD resolution due to the size and cost of making 4K content.

To overcome this situation, TV manufacturers use 4K upscaling. Upscaling makes standard definition and Full HD videos look better on a 4K TV. However, if you are noticing the videos coming to your TV are taking only a quarter of the screen, it means your TV is not upscaling successfully.

If you are also troubled by this issue, here are a couple of troubleshooting tips to fix 4K TV not upscaling problem.
