One of the biggest problems with any Raspberry Pi, even a top-of-the-line Raspberry Pi 4, is that it can't handle streaming video very well, at least not by default. When you fire up Chromium, the default browser in Raspberry Pi OS, paid streaming services such as Netflix, HBO Go and Disney+ just won't work, because the DRM (digital rights management) software they use to protect their content is incompatible with the ARM version of the browser.
YouTube videos don't suffer from DRM issues, but they are sluggish and drop frames when you try to play them at full screen, no matter the resolution. Amazingly, a developer named Ventz has come up with a way to solve both problems by running a specialized version of Chromium that comes from the Chrome OS source code.

By default, you can't run Netflix on Raspberry Pi at all and YouTube drops frames.
