How to optimize your setting with the best 4K upscaler?

Upscaling 1080p to 4K is not an easy task, as it requires a lot of processing power and intelligent algorithms to interpolate the missing pixels. However, with the right software and settings, you can achieve amazing results that can rival native 4K content. Here are some tips to help you get the best results when upscaling:

tips to get the best 4k upscaled videos
  • 1. Use high-quality source material: If you upscale a low-quality video, you will end up with a blurry mess. It is better to use 1080p source video to get 4K upscaled videos.

  • 2. Adjust the setting carefully: Take advantages of settings like sharpness, noise reduction, and color correction.

  • 3. Use qualified hardware support: Upscaling is a resource-intensive process, and it can take a long time to complete, especially for long videos. A qualified hardware matters a lot. 

Following these tips ensures excellent results when upscaling 1080p to 4K. Remember to use high-quality source material and select the appropriate upscaling algorithm. Adjust settings meticulously while considering hardware acceleration, and avoid excessive adjustments.

Why do I need a 4K upscaling program when my 4K TV can already do it?

The short answer is that if your 4K TV already has a native 4K upscaling feature, you don't need a 4K upscaling program. Because manufacturers all have their own 4K upscaling algorithms, the output video quality of each 4K TV may vary significantly from one brand to the next. Some may give satisfactory results, while others may not. If you're not happy with the results, your only option is to use a software 4K upscaling solution; after all, changing to a new 4K TV isn't realistic.

Does 4K TV upscale 1080p videos to 4K?

Yes, most 4K TVs today from major manufacturers such as Samsung, Sony, LG, Panasonic, and others include this 4K upscaling option. 

Does upscaling 1080p to 4K really improve quality?

However, it is important to note that upscaling does not generate details that are not present in the original source. It will not be better than native 4K.

The original 1080p content had a resolution of 1920x1080 pixels, and when it is scaled up to 4K (3840x2160), what happens is that each pixel in the original content is represented by multiple pixels on a higher resolution display. The noticeable improvement in picture quality is due to a number of factors: advanced upscaling algorithms, viewing distance, screen quality, fill factor etc. And UniFab Video Upscaler AI acting as the best and cost-effective 4K upscaler, driven by AI technologies and powerful algorithms, can make the best of upscale 1080p to 4K ensuring true details are preserved.
