With all the different resolutions for the phones now these days.
What resolution do you use?
I am using 1000 x 1750 for the longest time, but wondering about that now.
I use 568x320 for most of my my retro games.
but especially annoying when you have to deal with the black notch aswell. & are even all the iPads 16x9 ratio? get those black bars rolling
True 16:9 Resolutions
Modern monitors and tv's use 16:9 widescreen output. Using a smaller 16:9 output size like 640×360 or 1024×576 will have you be able to play your game in fullscreen with no lose in resolution.
1920×1080 all the way
I use 1280x720 for my desktop apps every time, and I also be sure to set them to scale to the screen they're on without changing the resolution. Basically, I set the application to maximize at start with no headers or menus so it can "go full-screen" without changing the desktop resolution
