hello,
Resolution noob here. Please don't be alarmed.
I am trying to understand resolution & ratio.
Below are the talked about resolutions, I think. (what you are using and what the switch outputs)
They are all exactly 16:9. Am I wrong?
So I think I do not understand why your game looks distorted in some cases. :)
480/270 = 1,777778 (16:9)
720p - 1280/720 = 1,777778 (16:9)
900p - 1600/900 = 1,777778 (16:9)
1080p - 1920/1080 = 1,777778 (16:9)
(Note: one entry in the wikipedia article has 720p using a resolution of 1366x768, which has not the same 16:9-ratio as the resolutions above. But I understand the Switch does not use 1366x768?)
(sources: 2 wiki articles: one about the switch and "list of common resolutions")
