How to Convert 1080P to 4K in Real UHD Image Quality

Posted by Delaney to convert video for TV, 4K video converter | November 16, 2017

Nowadays, computer monitors, TVs and even the latest mobiles support 4K. But let's face it; though Netflix, Amazon, and Sony are offering movies and TV shows in 4K resolution, it's still far from enough. Not until there is more 4K content, you can't get the most of your device. There is a solution: 4K Ultra HD TVs, as well as a number of Blu-ray players and Home Theater receivers, include the 4K upscaling ability that can improve the incoming 720P/1080P to as near as 4K.

But TV upscaler is not perfect:
1. Lost HDMI signal when upscaling to 4K content - "I just bought the UN65MU8000 tv but it frequently loses the hdmi signal when I click to play 4K UHD content (both from Netflix or Amazon Video). I have to unplug the hdmi and re-plug it back in for the TV recognize it again."
2. Blank TV screen - "I have a Samsung UE65HU7500 4k. When i upscale video to 4K play on the tv, the screen becomes blank."
3. Messed up quality - "I try to play a HD video after i set the system to 4k, but the video playback is totally messed up and blurry. Any idea on what's changed/going on? I think it should give me better output."

Expensive 4K TV has good 1080P to 4K upscaler engine built-in. They will generate quality close to 4k from 1080P, 720P or any other videos you input, unless the import video is really poor in quality. But those TVs come at extremely high price (for example, the Sony FWD100Z9D is priced at $60,954.66), while with most others, you may have above problems. Those problems aside, the TV 1080p to 4k upscaler allows you to play 4K on TV only. What about other 4K displays? In this guide, we will show you how to convert 1080p to 4K resolution and turn everything into the UHD quality, so that you can play 4K on uhd TVs or upload to YouTube, Vimeo and other 4k host sites. All you will need is a piece of HD 1080p to 4K upscaling software.
