Nvidia resolution set lower by default then what's supported by my TV?

So looking around in my display adapter settings I came upon the menu for Adapter> List All Modes. The modes listed were all different resolutions and Hz that are supported by my TV. It was set to 3840x2160 60Hz, but then i saw 4096x2160 60Hz was also supported. I switched it to that and it looks good. Infact the display/picture looks crisper then it looked before. Why would Nvidia not select the best available resolution supported by my TV? To be honest I didn’t even know my TV support 4096x2160, is that a weird resolution or something?

Why would Nvidia not select the best available

Without knowing the brand and model number of the TV, I’m assuming 3840x2160 is the native resolution of the TV.

You are correct. the Native resolution is 3840x2160. The TV is a TCL 55S546.

the Native resolution is 3840x2160

This is why Nvidia “picked” it.

okay, after using the 4096x2160 resolution for a few hours I decided to switch back to the native 4k resolution. While it made things like desktop icons and graphics sharper it actually made videos look like crap. Watching a 1080p youtube video looked like I was watching a 480p video. When I switched back to the native resolution it went back to looking better. I also did a little bit of research and found out the major reason it uses 3840x2160 is because that is the resolution supported/used by most 4k video content, I was getting black bars on the sides of videos when in 4096x2160. So long story short I now get why 4096x2160 was not chosen as a native resolution even though it’s supported.
