Bests & Worsts Reviews from Amazon

We are replacing a gen 2 Sony 40" XBR LCD tv from about 15 years ago that is edge lit by florescent lights. This new 43" LED LCD has phenomenal color, but it is much darker than our 15 year old florescent LCD...even on custom picture, brightness turned up, and automatic dimming turned off. If it had the ability to be as bright at the 15 year old model, I would give it 5 stars. UPDATE: Feb 25, 2020: We've been able to get it brighter by reducing the Black Level settings. Now we are having a 'picture jumping or stutter' problem with fast camera cut scenes, like on Food Network "Diner, Drive Ins, Dives". I've disabled both of the motion smoothing features and it still is happening. Not 100% sure we are keeping it. UPDATE: March 7, 2020: I've been able to solve the majority of the problems with the picture being too dark. We were still having issues with picture 'jumping or stutter', so I reached out to a high-end a/v store in the area. He said it's a great tv and we should buy new HDMI 2.1 cables, so I bought an 8K HDMI 2.1 Ultra High Speed 48Gbps on Amazon ($19.99). It has helped but not solved the picture stuttering completely. I have turned off all the motion smoothing settings and it doesn't make it any different. The a/v store is now suggesting that it's the quality (or lack of) from our cable tv provider (Comcast Xfinity). 4K HDR10 content on Amazon Prime and Netflix does not seem to have the stutter issue.
