I heard the Surface duo having an 11 megapixel camera, but able to record 4K, whereas I have a camera that’s 20 meagpixels but only 720p, and the camera on my phone is 13 megapixels and 1080p. Can you please tell me why? Does it have to do with sensor size?
​
Thank you in advance.

They’re basically the same thing.
“Resolution” typically includes the size ratio, but otherwise it’s just a measurement of pixels.
A still camera generally only needs to take one picture, and so can take a relatively long time to do it. With video you have at least 24 pictures per second, usually more. So the resolution of still images can be way higher. Video is restricted in quality by having to put out so many images per second.
Your brand new £8,000 TV would seem a lot less impressive if they advertised it with a MegaPixel count from 20 years ago, which is one reason they don’t like to use the same number for both.
