    Got a c7v and it seems I have to view the tv at 35-85 degrees or else suffer discoloring and yellow whites. Off-angle the tv looks awesome and corresponds to the color temp(cool and blue), but when directly viewed it gets a yellow tinge. It seems to have the reverse problem of VA panels. Is this normal for OLEDs or do I have a defective screen coating or something?

    2017 Oled Yellow/Red Tint . Long thread, my 65" has this too. Seems the 55" is less prone to this, but as far as I know all 65" OLEDs suffer from this.

    This is colour shift, and not the yellow red tint in that thread. The shift is caused by the polarising filter to reject ambient light.
    You are not seeing yellow whites as such rather the correct image when dead on centre. You then get a blue tint when off centre.
    If you adjust your white balance, you can change those yellow whites to be more blue. However, off centre your whites will be even blue-r if you see what i mean.
    It's funny how nobody other than AV Forums Phil Hinton has mentioned this trait...

    Yeah well, could be colour shift. In fact I'm pretty sure the difference in colour tone I see is due to the AR filter...BUT...problem is, the shift is there when I sit directly in the middle of the tv. When I move (pretty far) to the left, the left becomes clear and has the correct colour balance, but then the right gets a bit worse. Same other way around. When I sit right in the middle, the left has a clear colour shift, the right too but little less pronounced.

    Can you link me the discussion where Phil Hinton mentions this color shift issue? Could getting a different unit fix this issue? It seems the color shift affects whites the most and shouldn't bother me when watching movies or playing games (unless when there's lots of snow), but web browsing is very bothersome (sites with loads of whites like avforums and reddit). It's really bad when a 400€ budget 4k tv can display white websites better.

    Many OLED's do have this issue if it bothers you a lot get a exchange.
    It can also be reduced by getting your set calibrated.

    I can't believe rtings.com rates this as "the best tv" for pc monitor usage. Even at 100% brightness the OLED gets decent brightness at best, not to mention you constantly have to fight with the ABL and ASBL (dimming every 60 seconds) when web browsing.

    Found this video on youtube:
    LG 65C7 color shift

    Ignoring the staining that OLED has on the left side (srsly I hope he returned it), I seem to have the opposite effect seen on this video, instead of whites becoming yellow off-angle my oled has yellow whites when directly viewed (even with maxed temp) and proper bluish whites off-angle. It seems there seems to be balancing act in the manufacturing process.
    I am going to check some of the floor models if or how badly they have this color shift issue (and which way the color shifts).

    This is my video. What the video maybe doesn't show, is mine is the same. I get yellow whites when viewed directly too, mainly to the left side. The yellowing shifts when going off-axis, but when I sit perfectly in the middle, it's yellow for 10% on the left, 50% ok, then 40% yellow on the right (less so than on the left).

    Yep, I have had similar experiences although my last was pink.
    Never had a good one, very jealous of those who have.

    Your model has the red/yellow stain issue, which is a separate issue, but it does produces the same problems (off-color whites). My oled doesn't have red/yellow stains but instead has a effed up color shift.

    Strange thing is, when filming/photographing this, it appears reddish. But irl it does look more like yellow. Very hard to photography when viewing directly, in fact pictures look fine but irl it is definitely there.

    Ok, I managed to check all 4 OLED models in the store, specifically the sony a1e, c7v, b7v and e6v, and they all had the same yellow colorshift when directly viewing white content. I am going to check another store.

    My last one had 2 yellow stained areas straight on, but if you moved up to 70 degrees the yellows would change from yellow to white to blueish white.
    I sat on the left side and I’d see yellowish white on the left side my wife on the right side wouldn’t see it as much.
