How To Set Up 16:9 Resolution With HiDPI On Mac

Today, all of the mac laptops comes with a 16:10 screen. If you’d like to record a 16:9 video on it, it’s going to look weird. Forcefully setting the mac screen to a 16:9 resolution will make the text blurry, because it is missing the HiDPI support. In this article, we are going to show you how to set up a 16:9 resolution, e.g., 1280x720 (720p), on a mac 16:10 screen with HiDPI support.

Step 1: Install SmartResX

The first step is to install SwitchResX. Just follow their website to install it. It should be pretty straightforward.

Step 2: Create A Custom Resolution

After SwitchResX is installed, you want to make sure that we have a custom resolution which is 2 times wider and taller than your target resolution. For example, your target resolution is 1280x720 (720p), you want to make sure that there is custom resolution which is 2560x1440.

Open SwitchResX, and click on the target monitor. Go to the Custom Resolutions tab on the right. Create a new custom resolution by clicking the ‘+’ button on the bottom.

Step 3: Select The Target Resolution With HiDPI

After you finish step2, reboot your mac. Then the HiDPI 1280x720 (720p) resolution should show up in the “Current Resolutions” tab.
