Hands down, S95C is one of the best OLED displays in its generation.
This video is specific to testing the Moonlight Tizen streaming on a Samsung S95C OLED TV

Results:
Both 4k 120fps 80Mbps and 120fps 120Mbps had some minor but noticeable slowdowns during panning shots suggesting TV processing limitations. For example, compare the turn animation in 00:34
Wired connections remain superior for competitive gaming and 144Hz refresh rates.
Wireless streaming excels for less demanding genres at 4K 60fps 80Mbps.

Recommendations:
Competitive games: Wired connection for minimal latency and 144Hz support.
Every other game: 4K 60fps 80Mbps wireless streaming for visual fidelity, flexibility and smoothness.
Movies: 30fps wireless streaming is more than plenty for most content. 30fps 80Mbps.
Set and forget for other content and regular work: 4k 60fps 80Mbps

Additional Notes:
Explore AV1 integration for potential streaming enhancements in the future.
Consider TV processing limitations when choosing wireless setups.
Wired connections remain ideal for the most demanding gaming scenarios.

Samsung S95C OLED TV Specifications:
Maximum HEVC (H.265 - Main) 3840x2160: 120fps 80Mbps
Maximum AV1 3840x2160: 120fps 40Mbps (not yet supported by Moonlight Tizen)

To find out the best settings for Moonlight Tizen on your Samsung TV, you need to know your TV's model group. You can look it up here: https://developer.samsung.com/smarttv/develop/specifications/tv-model-groups.html

For example, the S95C belongs to the 23TV_PREMIUM3 (UHD) group. Then, we need to check the video specifications for this group here: https://developer.samsung.com/smarttv/develop/specifications/media-specifications/2023-tv-video-specifications.html

We can see that the maximum frame rate and bit rate for HEVC (H.265 - Main) 3840x2160 is 120fps 80Mbps. This is the codec that Moonlight Tizen uses by default. However, Moonlight Tizen defaults to around 100Mbps at 120fps, which is higher than the TV's limit. This means that we have to lower the bit rate to 80Mbps or less, which will affect the image quality. If we are satisfied with the result, that's fine.

We also notice that the TV supports AV1 codec, but only up to 120fps 40Mbps, which is even lower than HEVC. Anyway, it is not supported by Moonlight Tizen yet.
