Step 4: A pop-up window appears. Select one of the three preset sizes (shown on the left). Otherwise, choose Define custom dimensions for a specific size. Another pop-up window appears (shown on the right).

Step 5: To keep the aspect ratio, select the box next to Maintain aspect ratio.

As you enter a number into one of the boxes, the other box will automatically adjust its number in proportion to the number you just entered. If the aspect ratio doesn’t matter, don’t check the box, and enter the numbers in both boxes.

Smart displays have promised to run my entire house for years. However, I mostly end up using them as fancy kitchen timers or home security monitors. Amazon’s newest one wants to change my mind, and it comes with a serious price tag.
