    Amazing

    The picture quality is amazing. It looks like the people are literally jumping out the TV. That’s how clear it is and it’s very light wait.

    Excellent QLED TV Performance for The Price

    I bought this TV for my living room where ambient light and glare might be issues. This TV does a great job at handling both. Most importantly, I was looking for an economical option that offered QLED technology in a 65” diagonal screen size. This product fit the criteria. For the price point the picture quality is phenomenal and gets even better with some adjustment, Google AI search “best picture settings for Toshiba 65M450SU“ it will help. I was pleasantly surprised also by how great the built-in speakers with Dolby Atmos sound. If you will be using this TV with an Apple TV 4K, DO NOT enable the Toshiba’s “Ambient Mode”. It will cause problems with CEC power on & off control (e.g. Apple TV powers on, Toshiba TV does not). Also for audio control select HDMI CEC in lieu of TV via IR option. Overall I would highly recommend this TV to others.

    Toshiba M450S

    The screen is amazing - we replaced a 65" TCL that had pixel issues after 5+ years. We played Avatar - the picture looks 3D. Amazing - also is better sync with the sound bar than the previous TV . thanks to the sales man who recommended this model.
