I am currently using an MS Surface Pro 4. There have been internet issues including not being able to connect to realms, the marketplace, external/featured servers, and the pause screen on a world saying that your MS account has been disconnected and to try logging back in. When using the default/recommended resolution (2736 x 1824) almost everything internet-related doesn't work. The weird thing is, is that I changed the screen resolution 2 times and it acts completely normal with no internet issues.
Also, I am aware this bug report might be hard to understand so please comment with any questions

The two display resolutions that I used (and work) are 1680 x 1050 and 1920 x 1080
The issue might be power related since the default uses more screen and is higher quality
