Input Lag: 26.4 ms
With Interpolation: 110.7 ms
Outside Game Mode: 119 ms
The very low input lag is among the best you can find when you set the TV to game mode. In PC mode, the input lag is still good, at 34.9 ms.
The stuttering you see should be viewable on other sets. There's only one clue in your post. That audio mixer. I've seen folk that call themselves video editors burn up over rigs like that. They get upset so you give them time to simmer till they are ready to try again. The rig if it's like others is the cause. Not the set.
I am using the samsung JU6400 for video editing with the hdmi input.
My audio is run through a seperate audio mixer.
The tv lipsync is terrible.I expect a short delay but it is about 200ms.
I have tried game mode but then i see stuttering in face paced scenes and not much difference in lipsync.
Any tips to acheive the minimal delay would be appreciated.
