If you're connecting to your computer or a cloud computer set up with your account, the server screen resolution will scale to match your client display. You can force specific resolutions here, but please don't exceed 2560x1440 (1440p). When you're not an admin, the server screen resolution will not change because we assume the admin is controlling the server screen resolution. If you get a display resolution error with this, it is because Windows does not have the resolution you are requesting available. You will have to manually add that resolution to the available resolutions or choose a different resolution.
