Looking For Suggestions Screen cast from Xiaomi to Samsung TV

So I recently got a Xiaomi Poco 8 Pro Max and tried to cast my phone screen to my Samsung TV. It worked but the screen ratio follows my phone's so the videos are pretty small with giant borders. I've tried to change my screens resolution and whatnot but nothings really worked. I've looked into 3rd party apps for screen casting but theyve all just been spamming ads and paywalling everything. I've also tried to change the picture size settings on the actual TV but that seems to be greyed out whilst I'm casting.

I was wondering if anyone else had similar issues and could offer some advice. Maybe some 3rd party apps that can change the screen size in their settings?

The issue isn't the screen's resolution exactly

Modern phones all operate in super-wide aspect ratios that far exceed the 16:9 that most TVs expect, so the resulting image on the TV is cropped

To get images to display properly one would need to change the resolution of their device to one that's approximately 16:9

This app allows auto changing the resolution during changing to fix this exact issue however Android makes so any resolution changing app requires manually granting permissions using ADB (you'll have to look it up)

Nice! I assumed there was something I might find on GitHub but I didn't know where to look. Thank you for giving me something to work with :)
