I have recently bought this TV. I knew it wouldnt be as good as my 720 Panny plasma with regards to blacks and pixelation. Watching DVB 1080p its very good most of the time with some pixelation on blacks, 4K is great however I was watching this 1080p stream last night and noticed how bad the pixelation was. The actresses face was clear but with a black circle of pixelation around her, as if her face had been planted in the middle of it. I have set the picture settings to recommend for true movie and dynamic so is this normal for Netflix and the TV? Also using wifi with no buffer at all even on 4K thanks

I just read netflix blacks are bad and are pixelated as they are downgraded but this is bad. It was streaming at 1080p according to info. I can also see it in the likes of corrie too in dark scenes everything else is fine.

I have just found out its called macro blocking and its bad on streaming so probably why it looks like this on netflix?

When Macroblocking Is Most Noticeable
Macroblocking is most noticeable on cable, satellite, and internet streaming services as those services sometimes employ excessive video compression in order to squeeze more channels within their bandwidth infrastructure.
Macroblocking can also occur, to a lesser degree, during over-the-air TV broadcasts. Its effects are more visible in program segments with lots of motion (football is a common example) as that requires more video data to be transferred at any given moment.
Another factor that can cause macroblocking is the intermittent interruption of the broadcast, cable or streaming signal. If this occurs, you may see a momentary still image displayed on your TV or projection screen that is composed of squares and horizontal or vertical bars.
Macroblocking can also be the result of poor video processing and/or upscaling by the playback or display device. For instance, if you have an upscaling DVD player that cannot process and upscale video from standard to HD resolution fast enough, you may see some intermittent instances of macroblocking, again, most likely during scenes with lots of motion or panning backgrounds. Macroblocking might also be noticeable on TV, Cable/Satellite broadcasts (especially in sporting events) where the motion really fast and the and either the broadcast signal or your TV can't keep up. Also, if your internet speed isn't fast enough, that could also cause macroblocking issues with streaming content.

That looks more like banding/posterization to me that macroblocking/pixelling. It's following the contours of the shading.

I would reset the picture mode you're using for that, it may even be worth doing a full factory reset of the TV. That's definitely not normal behaviour for a mid-range TV like that.

Also, why no buffer? Buffering is a good thing. That could potentially be causing issues.

Use buffering for a start.
Have you checked your account settings to make sure it's set to high quality instead of auto ?
A lot of the non netflix films look crap due to low bandwidth/high compression, Warcraft looks like a SVCD rip.

that should have said "Also using wifi with no buffering at all even on 4K thanks " as in not freezing

yes first thing I did. I think it may just have been that particular stream at that particular time of night. I still get the odd black pixelation even on 4K but not as bad as above, that is bad. I review on amazon found same, see photo below

One I saw in currys looked excellent, I guess it must be a streaming issue. Have you tried another device running Netflix connected to it ?
