Grainy image with the QE85QN900B

[leila88]

I bought the 8K QE85QN900B QLED tv at the end of August. It was delivered and set up a month later.

Everything seemed good at first bit now when I watch stuff on streaming (Disney+)and on 4K player the image is grainy. The occasional film (Avengers: Endgame) looks fantastic. Yet a lot of the stuff I watch has a grainy look to it. 

I've fiddled with the settings. I've changed HDMI cables. I've gone back to factory settings. I've switched off intelligent mode, played with sharpness.

Even with the last Star Wars film (Rise of Skywalker) on 4K its got a grainy picture quality to it. This is on both a 4K player and Disney+ via streaming. It shouldn't look this bad, should it?

It could be this was always there when I got the TV.

Even when I watch animation shows which are HD still look really bad with a grainy quality quite evident in the background. 

Gaming is fine. Normal TV looks fibe but I do not use very much.

Is there something to fix this or is it faulty because its such a high powered TV that it can upgrade stuff and its therefore making things look worse?

Is there a fix for this?

Hi members_SfQwD..., I have the same TV. My experience of the TV is on the whole positive. Picture is outstanding with some reservations on poor quality broadcast sources. Software, needs work to improve it as its laggy and freezes sometimes. Had freezing on Disney plus too.
TV is set to movie mode (I don't use any other mode) and was calibrated to 200nits using my Galaxy smartphone, . I have blur set to 4 and judder set to 3 , sharpness either 0 or 1. I belive using the sharpness setting with a grainy picture will only make things worse. The TV is big enough to highlight poor material for example Std 576i BBC 1looks poor compared to BBC 1HD 1080. I find anything below 1080 is poor. I use Freesat.
Not surprising as everything is upscaled to 8k. Native 8K streamed from YouTube is fantastic.
Picture clarity setting has a noise reduction option which I don't use but may help you.
Overall, best TV I've seen and I've looked at plenty. had to mess with settings a lot until found what I liked the best. Hope you can do the same. If Avengers endgame plays well it does sound like its down to source quality and Or settings. E

Hi efx,
Thank you for the advice! I will certainly try what you've suggested!
I have also realised that if I sit further away from the tv I don't always see the grain. I didn't calibrate my TV with my smartphone. Is this something I should do?
I'm sure it is something in my settings rather than source quality as everything looked fine on my 4K tv when I had it!

Hi leila88, I'm sat about 12feet away from my TV and don't notice any graining normally. I do notice some on some films that are older. Probably because there using film so that's acceptable to me. I have calibrated my TV using my phone and I think it was worth it, although this is more for colour settings. Also it depends what phone you have but I'd recommend it if you can do it. I used professional configuration mode mode. This will set the brightness levels etc. for you. Sets the HDR too. I think it only works on Movie mode. Definitely steeraway from STD and Dynamic mode they tend to be too bright and have the sharpness cranked up.
Hope that helps a bit. Good luck. E

Hi efx,
I am definitely less then 12ft away. I'm probably only 8ft away. I can't really move back any further without changing my living room, and that isn't really an option.

I have a Samsung Galaxy S20 4k phone so calibrating should be something I can do.

I usually use STD mode. I find movie mode quite green though I can always adjust it! I have turned sharpness down to 0 with STD mode. I will experiment with movie mode though!
Thank you so much for all your advice!

Your more than welcome. E

I just wanted to thank you for all the advice as it appears I've now fixed the issues after playing around with the settings!

Though I am now getting the occasional blurring with very fast moving images and I've got blur reduction and judder reduction up to 10. But because I've been looking for issues, I now notice it! But it's not that disruptive so I could probably live with it... I probably just need to do an adjustment on my settings somewhere to fix that remaining issue!

Thank you for letting me know. I'm pleased you have managed to get the picture more to your liking👍.

[leila88]

Thank you. And I've now fixed the other issue! Had to turn judder reduction down to 0 to fix!
