4K OLED TV running a 1920x1080 resolution scale, but Photoshop image still is 4K size

I use a TV as my monitor and recently upgraded from a 1920x1080 LG LCD to a 4K LG C1 OLED. Running Mac OS 10.14 Mojave. For my setup (and eyes), I have the display resolution scaled to 1920x1080.

This works fine everywhere, except when I'm in Photshop. The image itself still shows as the native image size (now very small), whereas opening the same image in Preview shows it in the scaled size.

At first I didn't understand what was happening, but since doing some research found that even though Photoshop itself will resolution scale, images itself won't. I can get that and it makes sense for those who want to use a 4K resolution and see that picture nativly in 4K.

My problem is it's way too small for my ability to work. Are there any preferences/options where I can make the image respect the resolution scaling? I realize my request is strange, acknowledge my setup is unique and it's not what a normal person would probably do, but I'm still hoping to find some kind of solution to this.

Thanks for the responses. It's something I just never considered when upgrading to a higher resolution. I didn't even think it was an issue at first (and this also made me confused) because Preview even uses the 1920x1080 size, so I was seeing that.

What the others say is true, so you’re now getting more than one potentially right answer depending on what you really want:

If you want the 4K TV to act as a 1920 x 1080 px display so that 100% magnification in Photoshop is not too small, use my suggestion. The cost is that the 4K feature of the display will be completely wasted, because the UI will be unable to use the full resolution of the display, and some things might even look a little fuzzy.

If you want the 4K TV to display the computer UI at full sharpness, leave the resolution as it is (1920 x 1080 Retina) and use the other suggestions: In Photoshop, choose 200% magnification to use as your 100%. If your muscle memory is wired to press Command-1 all the time to get to 100% magnification, go into Edit > Keyboard Shortcuts, and change the shortcut for View > 200% so that it’s Command-1.

When Photoshop uses the operating system scaling, it scales the user interface not the image. 100% zoom in Photoshop is not a physical size. It means 1 image pixel mapped to 1 screen pixel. That way no scaling is involved, therefore no artifacts are introduced, and the image can be critically adjusted and sharpened.

If you want to see the image mapped 1 image pixel to four screen pixels then use View - 200% zoom.

Just zoom to 200%.

If you chose a scaled resolution in the Displays system preference, it might be 1920 x 1080 Retina (2x scaling). What you might need to do is force 1920 x 1080 non-Retina (1x). In other words, you have to select “1920 x 1080” that does not say “Retina” after it. If it doesn’t offer that when you Option-click the Scaled button, you might need to use a utility such as ResolutionTab, although I have not tried that in macOS 12. There are other utilities like that, but I can’t remember their names at the moment.
