Terrible Clouding!

I am experiencing terrible clouding with my new Oppo 203. Look at the upper half of the screen in the attachment!

I have an XBR75X910C which is being replaced due to defect, for a bit more I can get the XBR75X940D, does anyone have experience with both that can tell me if I should spend the difference?

Also does the 940D use the same glasses? I have 8 pair.

The 940D well trump the 910c by leeps and bounds. A very good set and upgrade for you.

Wow, I love the 910C picture so I look forward to the 940D, thanks.

Well, I got my third set today and looks like I got a good one. There's still some clouding on the corners, but it's acceptable and not noticeable during content at all.

Furthermore, the TV came with Marshmallow and local dimming seems to be working fine on HDR.

I don't use them in my setup but they are pretty effective at giving you much improved sound quality without the big swings in volume.
Thanks for that, I will give it a shot.
I have the Yamaha A1050 and I haven't come close to understanding all it can do.

I find it interesting some folks are receiving sets with marshmallow installed and yet Sony hasn't pushed out or made available the update on their website. Is this a new set or refurb?

I haven't noticed any flickering with the Sony glasses. I don't recall what my MotionPro setting is in my 3D Mode. I should check it out. Do you notice any difference in ghosting between the two glasses? With my Sony glasses I notice zero to moderate ghosting, but on average I'd say minimal. The ghosting is most prevalent in bokeh blur either really close or far off in the distance from the main subject in focus. It's one of those things if you don't notice it you're fine, but once you see it, you're always kind of looking for it. It may just be the TV, but wondering if different glasses have an impact.

It's a new set. Also, local dimming not working in HDR is fixed for apps, but it still doesn't work for HDMI sources.

Well, I spoke too soon. After this, we put the TV up on the wall and the clouding is back and even worse than on the first two sets.

Interestingly enough, the clouds (I have two columns of clouds, their position has been the same on all three sets I've tried) align with the screw locations for the VESA wall mounts.

I did some experiments with another set before, and taking it off the wall for a day made most of the clouding go away. Now this new set starts to exhibit clouding an hour after I mount it.

At this point, I'm thinking there's just something wrong with the VESA mounting mechanism. It seems as if the weight on the four screws is causing some sort of pressure and causing clouding.

Seems a bit far fetched, but it's the only explanation I have for seeing the same clouding pattern on three different sets and the clouding getting better after removing a set from the wall.

Kinda torn on what to do. With local dimming, the clouding is basically invisible. However, local dimming is still not working in HDR for HDMI sources and I don't have much faith in Sony actually fixing it. I could keep it and then invoke warranty when the 940E comes out and see if that one is better or I could just go the OLED route and live with 10 inches less.

Very disappointed in Sony, though. Last thing I expected after dropping 4k on a TV was going through all these issues.

Ya know, you could be on to something. Come to think of it, I don't remember seeing any clouding issues at all when unboxing my tv and checking it over when I first got it. Now that it's up and mounted I have 4 very pronounced "clouds" on each quarter of the panel. I also have mine at a downward tilt above the fireplace. The thought that this could be the issue for clouding has crossed my mind a couple times but I just thought maybe I was being crazy.

I'll have to run my own test and take the tv off the wall. I'll put it back on its stand, wait a while then turn it on to see what kind of results I get and report it back here. I'll take 'on wall' and 'off wall' pics to post and compare. Only thing is I won't be home till Tuesday to test this theory.

My Sony XBR-75X940D is wall-mounted and I have NO clouding issues. I have a wall-mount from Monoprice (Stable Series Extra Wide Tilting Wall Mount for Large 37 - 70 inch TVs Max 165 lbs UL Certified).

Any chance you could try turning off local dimming, setting the brightness to max, playing a black screen, and taking a picture? At this point I'm just curious about panel uniformity across the board.

I will see what I can do. I will try to get that done this evening.

Excuse the crappy cell phone picture, but here's what my third set looks like. The previous two were very similar. This is brightness at 35 with local dimming off.



For comparison, this was the first set.

Man, I wish the clouding on my Tv was that minimal. Your set has me wanting to have mine replaced. My clouding issues are much bigger and much more pronounced. Not to mention the issues I'm having with HDR content. I was going to just deal with it because the panel is so perfect in every other aspect but its bugging the ***** out of me!

I was considering just sticking with it, but then I also found 5 stuck pixels while taking a quick look. I'm calling BB tomorrow and getting my money back. Guess I'll have to settle for 65" and just go with the LG OLED.

Well I could be way off on this but bought the 940d few weeks ago installed the waiting update and pic went to crap. Picked up my new tv monday with a flawless pic and I'm refusing to let it update. Don't want to change a thing. Colors perfect on standard, no clouding anymore or blooming. Not saying the update has anything to do but not taking chances.

Are you saying local dimming is not working for HDR sources like a UHD player? How can you tell, since the local dimming control is grayed out when in HDR mode? Are you basing this by just looking at the PQ?

Can anyone recommend a reliable test to determine the effectiveness of local dimmming?

I had mine on the stand a few days before I wall mounted it and could discern no difference in the clouding between stand and wall mounting. My feelings on clouding/flashlighting , especially closer to the edges of the tv is the it has to do with the relationship between the panel and how its secured to the rest of the tv and the tightness of the frame around the panel. I can see some minor flashlighting and walk up to any corner of the tv that has it and flex the housing of the tv and it will disappear.

For comparison, this was the first set.

I know this is subjective and my own opinion but I don't find that clouding to be that bad. I've seen way worse on this model tv and other TV's in the past. Anything not OLED is just going to have some kind of clouding especially when you get to these size TV's. It's the nature of the tech in them. Personally, I would be satisfied with that clouding but I totally understand if you aren't. I read you found some dead pixels so kinda moot anyway. I'm getting mine swapped out next Wednesday and anxiosuly hope the clouding/smearing isn't worse than the one I have now.

Does the clouding go away with local dimming on? If yes, then why assess the PQ with dimming off? You would normally not view the set with the dimming turned off. Unless, of course, we come up with a test to assess whether local dimming is actually turned off in certain situations, which would be a bug IMO.

Personally, I would be satisfied with that clouding but I totally understand if you aren't. I read you found some dead pixels so kinda moot anyway. I'm getting mine swapped out next Wednesday and anxiosuly hope the clouding/smearing isn't worse than the one I have now.
The clouding on my set is not as "aligned" as in jr.calzada's pictures. There doesn't seem to be a pattern; it is more random, like the last picture in post # 7447.

I'll check with non-HDR sources, where I can set Auto local dimming to something other than Medium. I'm not sure, though, why local dimming would affect clouding on what is essentially a blank dark screen.

Exactly what I was going to ask. If there is no clouding with LD on, I'm more than happy. Don't really care what the set looks like with it off since I never watch it that way.

Would you mind checking to see if your software version is PKG3.709.0120NAB? TIA. (Found in the Home>Settings>Help)

I've lost track of whose clouding we're talking about, but assuming it's in HDR mode, isn't ALD set to "medium" and greyed out? There would be no way to see if it occurred with ALD off, unless, I guess, the source were somehow tweaked to avoid putting the set into HDR mode, right?

Oh, I wouldn't mind it much if it weren't for the HDR issue. When playing Gears of War 4 I have these four gray clouds floating in the middle of my screen and visible most of the time. Very annoying.

The test is crude, but gives a good comparison. The screen with the Amazon logo in Amazon Video series has a moment where the logo is relatively small and surrounded by a black screen. Pause it at the right time.

I've done this on the following:
- Amazon Video running on the TV, non HDR
- Amazon Video running on the TV, HDR
- Amazon Video running on Xbox One S, non HDR
- Amazon Video running on Xbox One S, HDR

For when running on the TV, did this on both my old set without Marshmallow and the new set with Marshmallow.

Non-HDR sources showed no clouding at all other than a bit immediately surrounding the logo. You can clearly see most of the zones are off.

On non-Marshmallow, all HDR sources show all the clouds clearly, including the ones at the corner. The black is mostly gray and the zones are clearly not off.

On Marshmallow, HDR from the app on the TV shows no clouding and solid blacks. Screen is black. Zones are clearly off. HDR from the Xbox, though, looks the same as on non-Marshmallow.

The setting is locked at medium in the settings, but that seems to be a bug. Also, the picture mode for the Xbox is HDR Video.

@jr.calzada , who has just replied as well, has claimed that the clouding he sees in HDR screens is being caused by local dimming being disabled, even though it shows to be on in medium mode. I simply asked the question how he could be sure it was a local dimming issue and not something else. In his response, he gives reasonable evidence that seems to support his claim. However, I am not convinced that something else is not going on that is causing the issue. Regardless, no one is disputing the fact that he sees an issue, and it is concerning him.
