P: Support scalable user interface UI for high resolution monitors

Unfortunately, that did not work in my case.

Thank you for your input.

I'm going to probably make everyone here feel stupid but I think I have the easiest fix yet.

Right click on the app icon
Click Properties
Click compatibility
Enable this so it has a checkmark disable display scaling on high DPI settings

It isn't a "fix", but a major feature in a newer version of the software.
And Photoshop CS5 was released many years before high DPI displays became available on Windows.

Well isn't that a kick in the pants.

No software company, Apple, Adobe, Microsoft, or any other, goes back and retrofits old software. It just isn't going to happen; no company has the desire and resources (developers) to do so. To expect Adobe to do this to CS5 is not reasonable.

I fully understand that Adobe wants everyone to go to CC. However, I do not see the need to pay for a subscription for a program that I already have and should be able to use on a hi-res screen. If there is a fix for the cloud based product, then it should also be made available for the computer based programs as well. My initial outlay for CS5 was not cheap when I bought it five years ago. It works fine with the exception of the use on a hi-res screen. Come on Adobe, how about ponying up and fix this problem for those of us who have paid for the license of a program that we loaded on our computers.

Did you restart the application so the change could take effect?

Oh.... I tried "Scale UI 200%" and it didn't work.

See the answers at the top of the topic.

I have also a hi definition monitor, and I have Photoshop CC 2015. How do we find that setting/feature in the latest version of CC?
