Q80T / Q90T Owner? What is your experience with Dirty Screen Effect (DSE) ?

Hi all,

I purchased a Q80T last week, a great TV but I had to return it due to DSE which was noticeable during football. I replaced this with a Q90T, however it has the same noticeable DSE. After some research, this clearly seems to be widespread.

I'm running this thread on the Official Samsung TV Forums, AVforums and on Reddit in the hope that we can gather some experience on the issue. Whenever I try to search for people's experience on this, it is fairly difficult to gain a decent number of experiences.

My main questions are:

1) Have you experienced this with a Q80T or Q90T, if so, how much? Is it noticeable during sports to the point of being a distraction?

2) How is it for games? Noticeable on skyboxes / games like FIFA or Sea of Thieves where the colour is uniform?

3) Did you replace the TV and receive an improved panel?

4) Did you have an engineer replace the panel? Was this an improvement?

5) Do you have any pictures of your panel which could indicate the severity of the issue? This may help add to a solid 'bank' of experiences.

I am basically with a Q90T where the returns period runs out in two weeks. I am trying to determine whether it is worth sending back.
 
I have a Q95T, i don't suffer from DSE , i made some tests yersterday using skyboxes in games.

from your pictures , what you are watching is not DSE , but uniformity problems linked with local dimming. Uniformity can be checked with a flat colour surface. DSE is kind of grey dust on a static place, that is only visible on moving /panning scenes with a sky with near uniform colour.

try to set the local dimming to low , it may be less visible. for Q80T owners , it has lower number of local dimming zones and will show more uniformity problems. but i see uniformity problems too on my Q95T. it is not a tv sample problem , it is linked to this technology, the only thing you can do , is too lower the luminosity settings and set local dimming to low... or buy an oled.

It seems to be prominent in showing horizonal and vertical lines down the screen when watching sports and looking at skyboxes though?

Encouraging that you don't notice it on skyboxes. I must admit those pictures were taken hastily before I went to bed. I'm having real issue with games like FIFA, the lines are like a set of vertical blinds that sweep across the screen. Not much change even when clicking to low dimming mode or adjusting the backlight.

I notice a gridlike pattern on mine. It can be really annoying if you know that it's there. It's almost never visible in movies though.
I guess this TV is not suited for ice hockey fans.
