You get 4k Ultra HD pictures that are delivered with over 8 million pixels. Picture quality is 4 times sharper than what you would get from a regular 1080p high definition television. The Dynamic Motion Rate 120 feature makes it a great TV for fast-moving sports content or video games.


Gamers will also appreciate the V-Gaming Engine™ feature that optimizes gameplay on consoles like the Playstation 5 or Xbox. It provides improved 4K HDR picture quality, more responsive gameplay, and smoother graphics.

Smart Features

It comes with a variety of free streaming channels so you don’t have to pay extra to enjoy great content.


Besides the Smart Remote, you can also use voice controls to control and navigate through the M6. It’s compatible with all the popular voice assistants like Alexa, Google Assistant, and Siri. You can even use it to control other smart devices in your home like lights or to check who is at your front door camera.


The M6 is ready for next-gen gaming consoles like the Playstation 5 and Xbox Series X with three HDMI 2.1 ports. It makes it compatible with all the newest 4K devices.
