Thank you for reaching out Surface Community. To change the screen resolution:Go to Settings > System > Display > Resolution > From the dropdown select 1920x1080
Once you have selected 1920x1080 you will be prompted to Keep changes or Revert. See the screenshot below.
You will see the resolution as well on how
1920x1080 looks like within 15 seconds. Tap Keep changes if you'd like to keep the resolution into 1920x1080 and Revert to go back to 2736 x 1824.
Mark my reply as an answer if that works for you! Looking forward for your response.
