It's HD 1920 x 1080. But on that resolution, everything is too small to read. 1280 x 720 is the ideal resolution for me on a 43" screem, but the writing is a bit blurred. HiDPI doubles pixels both way, so you get 4 for every 1. So it gets sharpened up. This M2 Mac doesn't offer that, but it does give 1024 x 576 HiDIP.. This means everything is slightly bigger than ideal, which is fine 99% of the time. I've had to swap to a lower resolution a few times, just for a minute, due to the "done" button not showing on a preferences box or something. I could use a third party app to give more resolutions maybe, but I'll see how it goes.
Going back to the menu bar icon, as well as eating valuable space, the other reason I don't like it is the more I have, the longer it takes me to see which one I want. It gets confusing. Again, I have low vision, so I probably have to look harder. And I have the menu and dock on auto-hide as I can't stand it being there all the time.
