I am experiencing the same issue. The only resolution option I see is 1792x1120; it's zoomed in and things on the border of the screen (like opponent's cards they play) are cut off, making it almost impossible to play.

Same issue with a MacBook Pro 2021 M1 14". It worked fine on my old mac

Mee too. I have an Apple M1 Pro 14" and when I play the screen is cropped.
Resolutions options on Arena are stucked on 1512x982, while my mac full resolution is 3024 × 1964.

The cards are cut off the screen - you can't even read the card that your opponent is using.

Please fix this!! Why haven't you fixed it yet?

Any updated fixes? None of the following worked for me. Big cut offs on both sides of the screen, no way to change resolution at all stuck on one option.

The graphic resolution cannot be changed on Mac OS.

Same problem here. This problem occurred while the client was running. At the defeat screen, the client pooped out of full resolution and forced the client to run at 1680x1050, with no option to switch back. Small window and terrible resolution at full screen with edges cut off.

Screen cut off the button to hide the stack. I couldn't activate my food token to save myself.

So far I haven't found a work around....

Please fix the Epic games client for Mac asap. Ever since the Vow update it has been a disaster. It is stuck on one resolution option that is either too small in non-full mode or doesnt fit the screen in full mode (and has cruddy resolution) at that size. Worse it is constantly getting stuck on the Defeat screen, failing to give a leave battlefield option and forcing a force quit.

Same problem with my MacBook Pro 2021 M1 14". Terminal line fixes do not work on M1.

Same problem here. Woogieboogy#70210, where would you need to input this code? In the plist file in Preferences Library? Or in Terminal?

Actually, what bugs me most is the low resolution in full screen mode...

Yep, I do have the same problem, 2020 MacBook Air M1, and as Woodyboogy has already pointed out, previous easy fixes do not seem to work anymore. Really annoying.

This fixed it for me

I have this same problem. Really annoying especially since "Low resolution mode" is no longer an option.

I used to be able to follow these steps to get a decent screen size
