Using: IFS Dark Room, Light 35-50, everything turned off that can give worse picture quality. For most of the pictures I turned up the brightness to about 55 to show the problem on the right side.
I haved used the TV for about 35 hours, run manual pixel refresher one time.
My B7 had a fault with the panel, so my store replaced with a C8. After watching some movies and series, I noticed that it looks like the TV has some light bleed on the right side corner, especially in the lowest right corner. This is OLED, not LCD, so I didn’t see this coming at all.
I saw this when I watched The Walking Dead Season 8 (episode 8), that is a brutal episode to test your TV I found out later. When watching this episode, I can see that the right side of the screen light up, while the left side is dark and black. I have checked other movies and series, and the problem can especially be seen in dark scenes that isn’t 100% black. This was not a problem with my former B7, as I have checked movies and series I watched on the B7.
The gray uniformity at 5% looks like crap compared with my last B7, and the B7 didn’t have this issue with something that looks like light bleed. I can see some vertical banding at 20% also. There are lots of bands. And there are also square boxes, that I also saw on my B7, but they went away after some usage.
What I discovered if I use a black test screen on Youtube and adjust the brightness from 50 to 52.54, the right side from the edge and inwards, turns brighter before the left side, so I see the problem directly when I adjust the brightness. I never saw this with the B7.
This isn’t perfect black, B7 had perfect black in my eyes, so is there someone who knows what’s going on with my C8 and others who have noticed this? I see that there are some others also who have the same problem, I have tried the manual pixel refresher, didn’t see any improvments.
Can it be something with the voltage, since the 8-series have higher nits, that LG has pushed the 8-series to hard, I think i read that somewhere, but that is out of my league.
I have also noticed much more compressed noise with the C8, and especially on the right side that is brighter, it looks like crap and I didn’t notice this so much with my former B7. My C8 is horrible with lower bitrates, I have never seen so much noise in darker lit scenes, it looks like it doesn't know what to do with darker lit shadows, it reminds me of a Samsung plasma i had for two days that couldn't handle shadows without trying to create something that wasn't there. I already miss my defect B7, and I think is going to be my last OLED for a couple of years if this is a new problem with the 8-series. Because my C8 looks like a cheap LCD-TV from hell!
I know that I haven’t used this TV so long, but I have a bad feeling and I have about three weeks to exchange it. What I’m afraid of is that others also have had this problem, so I was wondering if any of you can see if you also have this problem, because if, I’m out and I’m going to buy a Sony 9-series with lots of blooming
