User Manual Samsung UE55RU8000UXXU 55" Dynamic Crystal Colour Smart 4K TV

the Samsung RU8000 has a native refresh rate of 120Hz. It supports the FreeSync variable refresh rate technology. At 4k, however, the range is narrower, as the TV only supports resolutions up to 4k at 60Hz. Hope this helps.

Hi there, it sure is.

The RU8000 comes with a UHD Processor, so you'll get both true 4K, and 4K upscaling for non UHD content.

Yes, it has the option to set it at this resolution!

You can certainly use Apple Airplay2 on this TV, so long as the TV and IOS device are both using the same Wi-Fi. We hope this helps.
