Edge bleeding/clouding on BeoVision 11?

Hello guys.

For quite some time I have been annoyed the edge lighting on my BeoVision 11. It is visible especially during the evening when the lights are dimmed - but I can even see it during the daytime if I bring up the screen as it is shown in the picture. It is especially light from the buttom of the screen that annoys me. As you can see the upper right corner and the buttom right corner have this problem aswell. Is this normal on the BV11? Are the edge lighting not supposed to be dimming down when black background is shown? I know this is an edge lid LED but I think it is too visible. And here comes the weierd thing. It seems to disappear if I turn the TV completely off (disconnecting from mains and switching back on) Only to be visbile again later. I hope you guys can tell from the picture. I have no tripod for my camera so the picture got a little blurry due to det dimmed lights.

I also have some bleeding in the corners, specially visible with BR films, and the usual clouding when white is displayed on a white background. Regarding the former, i looked carefully at the seal between the panel and the glass, and I see defects in the seal that i believe creates the bleeding. What i found is having some ambient light in the room decreases the problem. I was very bothered by it at the beginning but now i just live with it. I am a bit disappointed by it as this is something that has been eliminated in some other brands a few years ago.

I always watch movies at night with at least a lamp on in the room, as this largely negates any interference. I must say I have never had a problem when actually watching a movie, except when the dynamic contrast comes into its own. This is of course a different type of light problem, but unique to this technology.

The sooner they use local dimming like on the 7-55 and the new UHD panels that are arriving, the better I think. That would be special, and considering the price you would think it would be standard on all B&O LED LCD screens anyway.

Thanks for your replies. Seems like I am not the only one having this problem. I jus re-read the article from FlatpanelsHD. Here is what they said regarding this matter:

"As the picture shows the uniformity of the backlight is close to perfect. Most edge lit LED screens suffer from clouding (spots of light) or bleeding (light “bleeding” in from the edges) in some way or the other, men the Beovision 11 really excel in this regard. On our 15 second exposure you can vaguely see that the top and bottom is slightly darker than the rest of the screen, but this is not visible during operation."

Here is the picture:

I think local dimming is *incredibly* expensive, which is why it's not implemented on the BV11. But, hey, with a BV11-55 costing close to £10K, you'd have thought the cost justified the best possible panel lighting! Isn't that why we spend £10K on a 55" B&O?

Luckily for me, my BV11 doesn't suffer from clouding. I think it's a bit hit and miss, based on the panel. When the recent Haswell MacBook Pro's were launched, there was a multi-page thread on yellow tinting and clouding issues on the MacRumors forum: http://forums.macrumors.com/showthread.php?t=1660649. Some users returned their new MBP three or four times, before receiving one with a uniform panel.

Clouding for me also on my bv11 but less anoying than on my bv10.

During movie or tv watch I don't notice it (wich is the most important) only with the menus.

You can see the tv "work" on dark scenes wich wasn't available on bv10.

Need to be used to it though.

You only see these issues on a blank black screen , I don't think too many people spend much time watching a blank black screen so I wouldn't worry about it too much tbh.

In the old days of CRT you had loads more problems to deal with - colour tizzing , moire patterns , magnets in speakers , picture going out of focus etc etc

Ahh , the good old days ...
