Xf9005 bright line above volume bar

Hello,

I am new to the forum and I would highly appreciate if you could help me with my -less than 2 months old- 65xf9005.I have noticed that when i increase or decrease the volume,15 to 20 cm above the bar, appears a bright line that highlights the hole area on the volume.Is it normal?I have already tried rebooting and factory reseting.I am attaching also photos of my problem.Any help or information will be highly appreciated.Thank you.

You have bought an LCD tv with local dimming, this is called blooming and it is due to the local dimming algorithm and it is somewhat normal for the technology used. It seems somewhat too high but this can be caused by the photo you took or some setting you use

Thank you for your reply i have one question though.Isn't local dimming supposed to light locally?why i have the hole horizontal place enlightened?this is my question.The height is the one i mentioned one my first topic even though the height may be frustrating through the photos.So shall i not be worried?

Yes you have a FALD tv the dim or brighten local zone. The problem is that your tv has only some 40 zones to play with so to brigthen the whole bar it has to light all of the low ones. If you look at the second photo in which you have another object on the left more zones are brigthened

As I said the general behaviour of your tv is normal (you may want to try to switchoff the local dimming if it bothers you but you'll lose the higher contrast it may reach). From the photos it seems too high but again it may depend on the camera itself or the setting of the tv (i.e. on vivid it may appear more that on cinema setting).

To be honest i use the cinema pro preset to watch tv.In the other presets it is not so bright but itnis still there.It is annoying though.

By the way to be more accurate about my problem I mean this bright area in case of misunderstanding.

Yes I have understood and be aware that blooming will be more evident off axis

Unfortunately I do not have a solution for you...I bought an OLED that does not have this behaviour

Sorry for the offtopic.Seems that updating to oreo has solved my problem BUT now when i do a black screen test via YouTube video there is some light blinking in the right down corner of the tv.Do you know what it might be?It hadn't done it until now.

Do not know which effect you see...an example? Did it happen also in normal viewing?

I have noticed it during a black screen test on a YouTube video.It is like in the bottom right corner some backlight trembling white light but with low volume.In normal viewing i have not still seen something since I haven't watched Tv from yesterday.This happened after my update to oreo.
