Hey all,

On my 55" Samsung QE55Q6FAM I've noticed it has this horrendous swirl type of effect when viewing dark colours in films or in YouTube, no matter what settings i try it doesn't seem to go away.

My old man has a 32" 4K Samsung LCD too (model number i cant remember) but his is the same too,Is this something Samsung specific? :D

I've noticed it seems to be really bad when watching YouTube, In 4K or bluray films however its perfect black.

Low quality source data, there just isn't as much information for loads of subtle colour/tonal shifts, so you end up with big messy banding.

A 64kbps MP3 will still sound crap on even the most audiophile equipment.

Crap in, crap out.

If you watched 4k HDR Youtube videos I assume it all looks great?
 
Sorry for late reply, Yeah if i watch 4k HDR looks stunning, But id have thought 1080p (which this video in screenshot was) would have been more than enough to not look like this :p
 
Can only give generic advice but make sure you are using the correct colour format (include full or limited range RGB as appropriate) and that image enhancements on the display end aren't messing with black levels too much, etc. the default settings on many TVs just try to make them look at bright and saturated as possible to appeal to the average consumer and can do nasty things to the image quality when you really get down to it.

I've found this more noticeable of late, even when correctly setup, with the lower bitrate a lot of places are using "due" to the increased demand/COVID-19 situation - a lot of Netflix content is quite bad for it, especially non-4K, when before it was OK.
 
Check if that's what YouTube is playing, I've had it recently where its not picked the highest resolution and it looks gash. I think they did it due the pandemic and to save bandwidth.
