* FIXED * Samsung UE40MU6120 flicker issue when gaming. See video description
*UPDATE: ISSUE FIXED. Annoyingly the issue was not to do with response times or the refresh rate or anything else. Turns out it was down to a glitch in the TV's settings menu UI. The SHARPNESS setting slider was reading 0 when it was in fact set to 100. Turning sharpness all the way down to 0 (which is what it should have been at) corrected the issue. Only took me four years to figure that out :D *
NOTE: this footage filmed on a phone camera as the issue only persists on the UE40MU6120 TV and cannot be captured any other way
Been trying to sort this out for a very long time and not been able to find any help anywhere. I have my Xbox Series X hooked through to my UE40MU6120 4K TV, and have noticed - mostly in Skyrim and Borderlands, but also some other titles too - that when I move my character or camera in-game I get this odd flicker. It's almost like all the lightest areas of the image, or objects where there are transparent textures - suddenly darken until I stop moving. I don't see the issue when routing the console through my Elgato and then onto a different monitor or to a live stream, so it seems to be the TV and not a console or game issue. It also existed when an Xbox One X was connected to the TV. It persists whether the TV's game mode is on or off.
I am using the official Series X cable, console is set to 4K and HDR on. On the TV, Game mode is on, and the HDR for all the HMDI inputs is set to on.
Any ideas?
