Amazon delivered my 65 VT50 Thursday. I was a little worried coming from a Samsung LED that the panel was going to be too dark for me. And then when first powering it on I was really worried! This panel needs to be calibrated as soon as you power it on or it will look extremely dark! I was used to Samsung who's panels come out of the box with a certain wow factor in my opinion. That being said once I played with the settings it easily blows away the ES8000 LED it replaced! The blacks show way darker and with much more detail. I am currently in the process of moving soon so please excuse the mess in the photos! I would have mounted it and possibly had it professionally calibrated but it makes no sense when I will be moving and the viewing conditions will change.
Ascetically it looks great! I have a light room with 2 large windows and a large sliding glass door and you can still easily see everything during the day. There is some glare on the screen when light hits it, but its not bad.
As for the buzzing you can definitely hear it when you stick your head near the top corners of the screen but once you're 2ft or more away you don't hear a thing. This was a little bit of an adjustment for me also coming from an LED that was dead silent with no fans.
Overall I am extremely satisfied with it! I don't care for THX or THX light room mode. I think the light room THX makes the whole panel look washed out...
Still waiting on Amazon to deliver my HDMI splitter so I can do a side by side comparison of the Samsung ES8000, so more to come.
