Hello,
Self explanatory title, after the firmware update which happened automatically for me today (1290.4), when I playback 24p videos from PC (HDMI), the display does not scale correctly. It is actually a little bit zoomed in and there is no option from the TV to change the scaling.
To replicate this bug you don't need to play any videos, you just need to change Windows resolution to any with 24Hz. 1080p 24Hz, 4k 24Hz whatever. Display is scaled and it is incredibly annoying.
Update 04-Dec-2019: I figured out that the resolution advertised by the TV is now wrong. When using any lower refresh rate than 60Hz (for example 30, 24) the resolution advertised for 1080p is 1842x1036 and for 4k is 3686x2072. I had to do a completely manual size scaling from nvidia control's panel to accomodate for this mistake. Where are my missing pixels, Samsung?
Update 05-Dec-2019: Turns out that the awkward resolutions are the result of nvidia resizing my desktop to compensate for the faulty scaling and not the monitor's fault. But nevertheless, this shows that when resizing the desktop, the result is actually having less pixels than the intended resolution which makes the picture blurry and not ideal for movie watching.
Update 13-Dec-2019: I have found a workaround. If you set your input to be of type "Blu-ray player" and not PC, then the problem with 24Hz disappears. But of course it increases the input lag so it's not suitable for gaming. So now we need to change labels before watching a movie and change it back to PC when finished.
Update 05-Mar-2020: Firmware update 1292.3 did *not* fix this issue.
Attaching pictures.

Hello @koale ,
I fully understand your frustration with changing settings every time depending on what you want to do because I also do the same 
New TVs have good reasons to have different features depending on what kind of device you have connected on and you basically change the presets by changing labels. For example the label PC always has the smallest input lag and most of the digital enhancement features disabled. When you have a Bluray device connected, it is safe to enable some features by default since noone cares for input lag when watching a movie. So it made sense to my mind and I had to try it.
I also play and watch using my PC always. I never use external players and I never use the TV's own media player (although it's a very good player). So my tips for you are the following:
1) When your source is 24Hz (most of the movies), you wouldn't want to change the signal to 60Hz because you are missing out on the optimal movie watching experience. This TV can play 24Hz natively since it's a 120Hz panel (120 / 24 = 5 which is a whole number, not a fraction meaning that it can playback natively without the need of mixing frames together for smooth playback).
2) When the signal is 60Hz and above you do not need to enable Motion Plus and you shouldn't. This is why when you are on 60Hz mode and above this feature is disabled.
3) Choose your media player wisely 
I always use Kodi with DSplayer and madVR because it's the best solution for HDR playback on PC. (here is a nice howto: https://forum.kodi.tv/showthread.php?tid=222576). It also switches automatically the display's refresh rate and resolution to match the source's. So if you use something like that, you make your steps even less.
4) When you have the PC label, I don't think that it's necessary to use Game Mode because from what I have seen around, PC label already has everything disabled and has the lowest possible input lag. The only difference that I have found is that Game Mode enables Motion Plus even when at 60Hz and above which is something that I don't personally like in games anyways.
5) Using different labels in combination with "Apply Picture Settings: Current Source" depending on what you do on your PC has other perks too. You can have your Bluray Player label setup to always have movie mode picture enabled so your movie experience is always optimal and your movie mode expert settings configured to have everything you want for movies ex. high backlight, high contrast, Motion Plus enabled etc. And when you go back to PC label, you can have your normal picture preset that you always had without having to go change that as well. So personally when I want to watch a movie all I do now is change label preset to Bluray and nothing more. Everything else is done for me by Kodi.
I hope you found this helpful! Have fun and stay safe
10 May and still no new firmware that solves this scaling problem....... Speechless
