2024 Best 4K Converter for TV | Fast Convert Video for TV

Get the best 4K converter for TV to upconvert 720p/1080p for 4K TV, or compress 2160p video to lower resolution for general HD TVs at accelerated speed.

4K, also entitled "4K resolution", is a new digital trend in recent years. There are many 4K resolution standards used in different areas, for example DCI 4K (4096x2160) used by Disney, Fox, Paramount, Sony Pictures Entertainment, Universal and Warner Bros. Studios.; UW4K (3840x1600) employed by Ultra HD Blu-ray discs and 4K PC gaming monitors; and also UHDTV 4K (3840x2160) commonly adopted in smart-hit 4K TV/computer industry. But no matter what, where there's 4K, there are some 4K video mismatching problems more or less, for instance:

- I've purchased a brand-new Sony 4K smart TV, and wonder how to play my previous 1080p movie videos on it clearly? Do I need a 4K converter for TV??
- I want to buy some 4K Ultra DVDs. But I don't have 4K TV equipped at my home. Is it possible to watch 4K DVDs on my TV with non-4K display?

4K TV industry runs faster than that of 4K film and video production, which leads 4K TV owners have insufficient 2160p video sources to watch. So here come the questions:

Q1. Can 4K TV play non-4K (like 1080p and 720p) videos normally and clearly?

Yes, they can be played normally in full screen. But the playback quality depends.
Any video that meets the video format/codec requirement of 4K TV can be played successfully. Because all 4K TVs are built-in with advanced video processing chips to upscale general SD or HD videos to 4K resolution automatically.

Real-time scaling algorithm, together with processing speed, affect the final image quality. So you may find out that different 4K TVs may display one 1080p video with discriminating visual effects. Also, it's nonsense and unadvisable to put poor original video at lower SD resolution e.g 480p/380p/240p on 4K TV. Because even the best scaling algorithm cannot make up the huge sacrifice brought by direct scaling.

Q2. How to Play 720p/1080p at Its Best on 4K TV?

If you want to have your 4K TV present 720p, 1080p video better, just upscale 720p, 1080p to 4K in advance with a third-party 4K converter for TV, which can not only optimize video quality of scaled 4K, but also release much performance pressure for 4K TV, focusing more on 4K signals receiving and imaging.
