This means that video upscaling tries to estimate what a lower-resolution video should look like if it was the higher resolution that the TV or video projector is capable of displaying. The video upscaling in a TV or video projector automatically activates when the content of a video signal doesn’t have enough pixels to fill the screen. What Video Upscaling Isn’tThe video upscaling process doesn’t magically make lower resolution into higher resolution. Video Upscaling Using Source DevicesIn addition to TVs and projectors, video upscaling is also incorporated into many source devices. Blu-ray Disc players: All Blu-ray disc players provide 1080p video upscaling for DVD playback and some also provide 4K UHD video upscaling for better playback results on a 4K UHD TV.
