Q90T/Q95T : Purple Ghosting (even with firmware 1460.9)

[BogaMoge]

Hey everyone...

So I have a question about Inverse Ghosting on my 55Q90T while playing on a PS4 Pro and a PS3 (I don't have a PC or a Xbox to test another hardware).
Since update 1460,9 (and after multiple factory reset) :

• no more inverse ghosting on Game Mode (Game Motion Plus OFF), but the picture quality is not what I expect from that TV (light color banding, very bad local dimming and weird dirty screen effects)
• inverse ghosting on Game Mode (Game Motion Plus ON), but some of the worse consequences of Game Mode are less evident
• inverse ghosting present in any other picture mode outside Game Mode (Standard/Movie/Filmmaker), but of course with a lot better picture quality all around.

So, my thing is I'm not strict about response time. Unless I'm playing a competitive online shooter or fighter, I don't really notice the difference. So I would like to enjoy the better picture quality of the picture modes outside Game Mode, but the inverse ghosting (especially in dark games or during night time in open world games) is unbearable.

What is worrying me is that as far as I know most people don't have any inverse ghosting issue after the 1304 patch.
Just to be clear, my "ghosting" looks like a purple silhouette that appears in front of dark objects on light(er) backgrounds when camera panning.

I thought maybe my panel was faulty, but then why would it go away with the patch in Game Mode? Also, the weird thing is that, sometimes, while tinkering with the settings, the ghosting goes away for just a little bit, and then comes back for whatever reason (without me changing anything).

Some games that will immediately show me inverse ghosting :

• Assassin's Creed Odyssey (HDR) : go to a temple by night an camera pan looking at the columns
• Red Dead Redemption 2 (HDR) : by night, look at the trees
• Ashen : inside a dark cave, look at stone columns
• Watch_Dogs 2 : by night, look at the trees in a park
• Dark Souls Remastered : first bonfire in Undead Burg, stand next the bonfire and look at the exit
• Call of Duty - Infinite Warfare  : asteroids in space missions

Thanks for anyone who can help, I'm at a loss here!

UPDATE 3 :

Here is a video taken on my phone of the purple ghosting. Look at the trees and the corpse on the floor :

UPDATE 4 :

Another video, with the purple ghosting even more evident :

Q95T owner here, and yup, extremely bad purple inverse ghosting. HDMI2.0 from PC to TV. 
Can't play any dark game because panning causes the screen to light up purple!
+ some images of how Game Mode ruins dark areas

Game Mode OFF 
Game Mode ON

Samsung never again. I’m tired of wait for updates. It’s inadmissible for a TV of this price.

Heh, same game I used in my example too! 
Agreed, Samsung should be ashamed of releasing any TV with these issues, let alone a premium model.

Turn game motion plus off.

If I turn off GMP the colours became inverted.

1-why should any mode create that kind of ghosting? it is unacceptable whatever the mode

2-with GMP off, the contrast/dimming is terrible (to the point of being unplayable for darker games) and there are DSE effects (especially some weird moving scanlines effect)

So nope, not going to be ok with a subpar experience on a premium tv.

So I was playing Death Stranding on PC and I came across this strange scenario where:
I could notice quite bad ghosting when playing the game at 4K60Hz.

I switched the resolution to 1440p120Hz (still 60fps set as max framerate within the game) and the ghosting went away.

Since the ghosting is kinda difficult to capture on video, I found this specific spot in the game where it's quite obiously visible across some black lines, and I captured that. Then I captured another video showing the resolution switch to 1440p from the Nvidia control panel and launching the game again, and no ghosting is visible in the same area.

Here are the two videos:

Q90T no ghosting 1440p120Hz:

This is on HDMI port 4 with an HDMI 2.1 cable, with PC and Game Mode enabled (Game Motion plus is disabled)

I hope this helps in illustrating the issue. Ask away if you have any questions about my setup.

Samsung needs to address this!
