Turning a Samsung smart screen into a dumb computer monitor
I recently acquired a Samsung "gaming" screen (Samsung 28" Odyssey G7 4K 28BG700) to be the monitor for my desktop. Unfortunately, it seems to want to be everything but a simple monitor for my computer. It really wants to be a computer and multimedia hub of its own, resulting in quite a bit of noise for my needs. Every time my computer turns on the monitor, it displays a huge overlay covering the entire lower part of the screen, showing a menu I can navigate with the monitor's remote controller. When the computer cuts off the display output signal, the monitor shows me a 1 minute countdown before it turns itself off. Sometimes the monitor spends so long turning on, the computer is already past the bootup screen. On the other hand, I have used the monitor's built-in OS to adjust and calibrate the image and colour settings. I'd prefer to keep these. How can I free the monitor of its misplaced soul, and get rid of all the noise, effectively making the screen a more "responsive", plain old dumb computer monitor?

I can't post a full answer since I never owned this model. But this might be helpful until someone else does.
From https://www.displayspecifications.com/en/model/87792ead I found that the OS for this is Tizen. Tizen is apparently largely FOSS and based on Linux. This made me think that the solution is not specific to your model, but all Samsung TVs devices with Tizen (about 15 years of models!). If you're able to confirm you have Tizen, it might be more useful to also ask a separate question about tinkering with Tizen TVs generally instead of just your model.
I then searched online for tizen smart tv jailbreak and discovered some interesting links, such as this forum thread which pointed me to the XDA forums section about Tizen and SamyGO. Samygo seems like a custom OS you can install on your TV, and perhaps it will have more useful features than the stock OS. Since it is Linux-based, you might be able to write your own script for it to bypass all the smart stuff at boot.
This is probably something to try if you have a spare weekend to kill (or three, depending on how technical you are). It would be useful if you could confirm whether you do have Tizen on that TV, what version, and if it's supported by SamyGO (they have a wiki about it).
