Good post. I also have black crush with VRR enabled but I have managed to get my game mode looking pretty dang good on pc with VRR disabled.I've reached out to Samsung a number of times regarding issues with this TV.
The more I experiment and try to get a decent image, the more this TV reveals how HORRID the firmware is.
Honestly, Samsung should be ashamed of themselves for releasing such a buggy mess.
Regardless, I am willing to work with Samsung to see this issues resolved. Else I will be chasing a refund, hopefully without needing to contact the ACCC.
The primary issue I have (since I bought the TV for this feature) is with VRR boosting black levels and seemingly ruining the gamma curve.
While also causing light posterization in certain scenes, particularly low light scenes.
VRR also has handshake issues sometimes, resulting in broken images displayed (like some previous posts here show).
Related, Game Mode damn near disables Local Dimming, breaking the proper brightness/darkness and depth that HDR content usually shows.
There's literally NO reason for this. If it is for 'lower latency' then make these things a damn toggle option in the settings somewhere.
I'm sure a lot of us would rather a proper looking image at the cost of a few measly milliseconds latency!
Second issue is, why does only PC mode display a proper RGB444 signal? While any other mode shows chroma subsampling regardless of what signal the TV is receiving.
PC mode FORCES contrast enhancer on while in game mode for some obnoxious reason.
PC mode also LOCKS color space settings and visibly reduces the amount of Local Dimming zones being calculated.
Again, all this breaks the proper brightness/darkness and depth that HDR content usually shows.
Third issue, local dimming when set to Standard or High will suddenly drop in brightness after a few minutes in most display modes.
Once again, this breaks the proper brightness/darkness and depth that HDR content usually shows.
Fourth issue, DSE and purple fringing around the outside of the TV panel.
Fifth issue, purple inverse ghosting (lessoned in the latest firmware, but still apparent when you know it exists).
What kind of botched firmware (and TV) is this?!
We all need to kick up more of a stink over this if you ask me.
For the record, I own an Australian Q95T with 1403.1 firmware currently.
If I'm not mistaken, quite a few Samsung TV models in 2020 share this same panel and firmware, and therefore would presumably share these issues.
More information and transparency is needed from Samsung.
Just waiting for them to fix this mess.
