Also just another thought, are you displaying the same as the laptop screen (mirroring) or is the TV acting as a second screen?
If you a mirroring it could be that the laptop screen native resolution is a mismatch with TV screen, eg laptop is 1366x768 and the TV is 1920x1080 and therefore it needs to be upscaled by the TV causing extra processing of the image. The way to solve this would be connect as an extension to the desktop then the TV will display in native mode ok.
Regarding the refresh rate, as far as I can find on the internet, the TV model you mentioned can do 60Hz so that shouldn't be an issue.2 -

Ive even tried it through fire stick direct onto the tv (as suggested on the thread that J B kindly gave ) and it still flickers the picture is great its just when the players move.0

I took a quick look at the TV specs and it says it has an 800Hz refresh rate, so that should be quick enough to avoid significant motion blur. So it could be the source - a combination of the stream and the laptop output to the TV.1

Common panel refresh rates are 50/60/100/120/240 with the upper end usually only appearing in high end gaming monitors.
If you want to compare the "800 Hz" PQI figure look at current Samsung models, usually quoting 1300 - 2700 on current models but they cannot be compared like for like with other manufacturers.1 -
Since the OP confirms that the laptop screen experiences the same issue then perhaps refresh rate is a moot point ... but would you happen to know what Samsung panels can accommodate? (A good LCD panel in a PC monitor for example would have 4ms refresh or perhaps even better. 50Hz equates to 20ms, so 240Hz would be 4.167ms).0

Refresh rate is the frequency of updating the whole screen with a new frame. If you are running 50 Hz with 4ms pixel response time, then that means that for the 20ms each frame is displayed, 4ms of that time (20%) is taken up by the pixels responding to the new state.
Potentially the pixels are in the wrong state of 20% of the time in the above example, but in reality most pixels won't change much from frame to frame, except where motion is occurring.
Agreed refresh rate isn't the issue with the OP, probably image processing ability of the laptop. Samsung panels will vary from 1ms up to 10ms depending on the model, in any case, all independent of refresh rate.
