I'm not sure if this is an actual problem or just me misunderstanding how screens/resolutions work.
My issue is this; whenever I watch movies, series or just YouTube, quite often it's at this really small rectangular resolution with black boxes all around. This will also occur in video players such as MPV and VLC when watching latest season Andor for example. However, it does not happen on all videos - which is why im confused regarding this.
My screen is an Alienware 34 Curved QD-OLED Monitor - AW3423DWF.
Is there a way I can scale the resolution up?
Let me know if I can supply any additional details and thanks for any help!
Because most videos have a 16:9 ratio and not ultrawide.
Not 100% sure but it also seems like the video in OP's screenshot (and other videos for said movie) is fake widescreen (bars baked into the video at 16:9) which makes it worse for actual widescreen displays. This may be OP's issue.
EDIT: in some cases an extension/plugin may work. One I saw mentioned is Ultrawidify, though it will probably heavily depend on how you are watching (for instance if you have the file, something like handbrake might be able to auto-detect this and crop as well if you're willing to do that). Though actual aspect mismatch will be a bigger issue depending on how often details will be cut off (crop/auto-zoom is a thing, better for a repeat watch or if you can quickly change it if needed).
Indeed, that's just how the video was recorded.
I literally did ... with the exact video in the screenshot on my own ultra-wide screen.
