Just received my 43in 4S
Is there a link somewhere to the optimal display settings I can follow?
I always wonder why people ask this type of question.
Everyone's house lighting may be different +
everyone's viewing preference may be (vastly) different.
So there's no one single set of settings -- on any TV -- that will (guarantee to) be ideal/perfect for everyone.
Also, some people may watch movies all the time -- while someone else may just mostly watch sports -- again the "ideal" settings will be different.
You just need to play around w/ the TV settings until the image on screen looks best/most natural to you. Simple
There's always a chance that --
my optimal TV settings may produce TV images that look sh** to you (and vice-versa).
I also have 43" Xiaomi Mi TV 4S.
I try not to over complicate things, so
on my 43" Xiaomi Mi TV 4S --
I only adjust the following basic settings:
(1) Color Temperature
(2) Brightness
(3) Contrast
(4) Sharpness
(5) Saturation
(6) Hue
(7) Noise Reduction
(8) Backlight
(1) Color Temperature: Standard / Cool / Warm
IMHO, (In my humble opinion)
this is personal preference.
No right/wrong choice. I personally choose 'Cool' -- because I prefer (overall) more white images & less orange/red tint across all objects on TV screen.
Some people say 'Warm' is preferred when watching movies. It's your personal preference that matters.
Set this first. Try all three. Decide which one you prefer -- then go adjust (2) to (8).

For (2) to (6), I make use of info at this two links:
https://calibracionhd.com/tv-calibration-screen-calibration-how-to-calibrate-monitor-fast-and-easy/
https://www.rtings.com/tv/learn/how-to-calibrate-your-tv
The above Web pages have images that you can download & display on your TV to help with adjusting the TV settings.
If you think the above articles are talking nonsense, you can search/Google for yourself -- MANY (MANY) other Web sites/articles that discuss calibrating TV (settings).

(2) Brightness: This is adjusting how deep/dark black on your screen should look -- without losing details inside dark scenes.
I've tried the range 48-56. In the end I leave it at 54.
YMMV (Your mileage may vary)
(3) Contrast: This is to adjust strength/intensity of how white objects should look on your TV -- without losing details on the white object.
I've tried the range 45-50. In the end I leave it at 48.
YMMV.
(4) Sharpness: In simple terms, this is to adjust & ensure that straight lines (e.g. edge of buildings) look perfectly straight without any (form of) distortions at all.
I've tried the range 6-8. In the end I leave it at 6.
YMMV.
(5) Saturation: This is to adjust the intensity of how strong colors should look on your TV screen.
This means if you set saturation to zero (or minimum) --- then you'll be looking at black & white TV images.
Again, this is (also) about personal preference. There is no specific ideal/correct setting that will suit everybody.
(Personally I prefer as low saturation as possible -- without TV images looking unnatural.)
I've tried the range 39-60. In the end I leave it at 41.
YMMV.
(6) Hue: This is to adjust the amount of red and green tint to the image on the TV.
I've tried the range -3 to +3. In the end I leave it at 0 (default).
YMMV.
(7) Noise reduction: Default value is 'Medium'.
If you ONLY watch high bit rate streams like 4K or Blu-ray -- you can set this to 'Off'.
If you always watch low quality streams like 360p/480p -- you can set to 'Medium' or 'Strong'.
You can trial & error to see if different selections on this setting makes any difference when watching TV streams of varying bit rates.
(8) Backlight: This adjusts the overall "brightness" of the entire onscreen TV image.
This is (also) about personal preference. There is no specific ideal/correct setting.
If where you place the TV has very good/bright lighting,
you can set 'Backlight' to a higher value.
If where you place the TV is dark / not well lit,
you can set 'Backlight' to a lower value.
In the future, if your viewing preferences change -- you can always go back & adjust any of the above TV settings.
Other than the above, I did not bother much with other Xiaomi TV settings. Of course YMMV.
Hope the above helps.
