Recently I've been bothered by the fact that channel banners are relatively low resolution. I figured there had to be a way to get a higher resolution, but when I performed the channel API request, I only ever got the bannerExternalUrl property, which returned a URL to a low-resolution banner.
I actually added the code that loads from bannerExternalUrl in ab625de24eda83ee41e07407b78f7f0a0d397629, because I discovered none of the other properties were ever returned by the API. At the time I didn't understand why, but after reading the Google documentation, I see that all of those other properties have been deprecated in favor of bannerExternalUrl.
But that still didn't explain why it was low resolution. I finally discovered that the plain URL returns a default image, but you have to pass a parameter at the end of the image URL to get a larger size. Fortunately, banners are 16:9, so if we want a banner that looks good on most computers and TVs, we can request it with a width of 1920. (We could go higher like 2560, but that might be overkill.)

Here is an example:
