Setting up a Better Display on your Retina Computer

One of the things that I noticed on my new iMac (Retina 5k, 27-inch, 2019) is that my screen resolution seems to be the same as my old Mac. I have a bigger monitor, but I am not seeing the difference in actual space.

Turns out that the issue is with the Display Resolution. I was using the "Default for display" which makes the display appear the same as before. I didn't know there's another option that can be set.

I saw a YouTube video which suggested to change the Resolution to Scaled and then select the "More Space" option. This set the contents of the display to be smaller - basically getting more use of the 5k Graphics card.

There is a disclaimer at the bottom of the Scaled section which says, "Using a scaled resolution may affect performance." I was wondering what type of performance degradation I would see.

In some instances you may see a slight delay after typing something before an action appears on the screen. This is a very small amount, we're talking milliseconds - but slightly noticeable.

It's good to know that changing the screen resolution doesn't impact the overall performance of the computer. So making the resolution change would be good to set up if your doing Movie or Sound Editing. Probably not good if you spend time writing a novel or email.

Works for Me

I like it because I can now edit personal websites and see them on the screen side-by-side.
