My 4k tv is showing a 1440p resolution on all browsers and my main 1440p monitor is around 1152p? Both the screens are on their native resolutions on windows 10 but it's all not showing for the web. Is there anything I can or need to do?

As you can see in the screenshot below, It's all good in the settings.

This is what I get in every web browser.

I should be getting UHD but HD content is only showing up.
