Monitor screen resolution

Easy question: How do we adjust the resolution of Resolve for large monitors? I set my laptop resolution to 4k so the desktop icons are super small (as intended) but Resolve opens up huge, like less than 2k. I'd like to use Resolve in a 4k resolution so that I can fit like 20 video layers on the screen at once. I can't seem to find a setting to adjust the program's displayed size.

Make sure Display Scaling is set to 100%.

But...you're situation is not ideal.

At 2160, I recommend a screen at least 32" is size. You ain't gonna get that on a Laptop.

No, I'm using a 55" LG OLED. I did set scaling to 100% and it works for the desktop but Resolve ignores it. It's like it's at 640x480 although it's most likely at 1080. Hoping to find a setting in Resolve like 'small' or something.

The Laptop's display is fully disabled? Using only the LG?
