First of all the picture quality is suburb. Do not believe about 240hz refresh rate. It basically talks about the motion smoothness. When turned on however, it looks weird and the sound seemed to be behind. So I had to turn off all the features it provides. It is locked at 60hz. I was expecting that because no screen is capable of 4k at 240 atm. I bought it for the dolby vision and image quality and not disappointed there. 4 stars only because the advertisement is misleading and that is not cool.
