Yes, there is flashlighting on this set. You will NEED to turn down the backlight in order to get rid of the flashlighting. You will notice flashlighting on letterboxed videos for sure, you will need to adjust settings and eventually you will be able to have a 100% black experience (letterboxed vids too)
Yes, that is the same experience I have from the two HX820 sets I've seen. At least on those two sets there was a little flashlighting in the bottom corners when watching letterboxed movies in a dark room (not very pronounced however, sometimes depending on content you really have to look for it to see it). Also the flashlighting is not visible when watching normal 16:9 content (even in a dark room), and not when watching letterboxed movies when the room is lit (even if the lights are quite low). I should also add that when watching off angle more than ~ 20-30 degrees, blacks gradually turn grey/blueish. But that is common for all LCD TVs due to poor viewing angles for the LCD technology.
Also turning down the backlight helps to reduce the flashlighting a bit, but not completely. Unfortunately, turning down the backlight also results in black crush (i.e. loss of contrast in dark areas, where dark grey also looks just black). So ideally I like to keep the backlight at 7 (i.e. default setting), since then there is no black crush, and the image looks fine for most content I watch. But in Cinema mode when watching movies I have set it to 5.
Finally, I might sound a bit negative above, but that's probably because I am somewhat of a perfectionist always looking for things to improve.
So just to clarify, in general I have to say I am very pleased with the picture quality of the HX820. Compared to other TV sets on the market it is definitely one of the best out there, and other sets have similar flaws too (most have many more flaws!). Many people just don't know what flaws to look for and how/when to spot them. Hence they often do not notice them (poor bastards, they don't know what they are missing!
). Also, I must add that the HX820 set itself really looks amazing!
But it will
be nice when OLED TVs start to arrive at decent prices, and we can all forget about flashlighting, backlight bleedning, clouding, black crush, low contrast, bad viewing angles etc that are all common for LCD sets.
