4K Screen set at 150% in Windows - cannot use menus and lassoo tool / selection tools are off from t

Hi

I have a 4k Monitor, set in Windows display settings to scale at 150%:

 

- this works fine in lightroom and other photo editing software, but not Photoshop. I have two specific problems (The UI looks great - no issues there)

  1. When I try and use the menus at the top and click on one it activates the menu two to the left
  2. When I try and use the lassoo tool or brush tool it actually brushes/selects away from the cursor.

I have tried the two main solutions that people seem to suggest, which is right clicking the photoshop.exe and changing the DPI settings in there to use the system ones, and the other is using a manifest file. Neither of these suggestions seemed to work.

I have three monitors - my laptop (which is set to 125% scaling as recommended), my 4K monitor set to 150% as indicated above, and a HD monitor set to 100%. Photoshop only works correctly when I'm on the HD monitor, or when I change the scaling in Windows on the other monitors to 100%. However, then the UI is too small and I cannot see, and this effects all other applications as well which work fine.

Is there a solution that allows me to keep my windows scaling as it is but allows me to use Photoshop on my 4K monitor as I would like. Most of the issues on here to do with 4K monitors seem to be fairly old - I suspect it is to do with my Windows scaling and it may be a Windows issue as opposed to an Adobe one, but it is only Photoshop that it effects.

Any help would be gratefully received, and apologies if I am missing something simple.

Many Thanks

Ian

Well after two weeks on chat with Adobe technical support I finally got to chat with an excellent Senior technician last night who has acknowledged this is a bug between Lightroom and Photoshop that happens in relatively unique situations. Nothing to do with the multiple monitor set up as it happens when the laptop is operating by itself. It has been referred to the Dev Team but if anyone else happens to come across this, until there is a fix, the workaround is to open Photoshop first, then Lightroom, and then the Edit IN Photoshop 2021 (or 2022 - the bug is in the updated version) will work as normal. It is not a scaling issue and at least now I can get on with editing. Many Thanks

Is there already a solution for this bug? I encounter the same problems when connecting my Dell Precision 5560 with 4K screen to my LG 27UN880-B 4K screen and also have this problem with a 1440p and a 1080p screen. When only using my laptop screen I don't have this problem. 
I'm running Windows 10 pro and the latest version of Photoshop (23.4.1) 

I have no Lightroom installed and I'm only having this issue with Photoshop, not with any other adobe CC program (AI, PR and AE all working perfect, with ID I have the problem that my mouse cursor is way too big but that's another story)

 

I really need a fix quickly as I'm using PS for professional work.

 

I've include some pictures to demonstrate the issue:

    I have the sam problem and nothing I do seems to be able to change it. Going from Bridge to photoshop does not solve my problem. Lightroom and Bridge are fine. Its a photoshop bug.

    I'm having the exact same problem. I cannot understand why Adobe does not have a clear answer on the problem and a clear fix for the problem. Apparently this has been going on for years. I needclarification and fix. If I find something more on this, I will come back here and post.

    the screen shots that YaniYaniYani posted above is exactly the issue I'm dealing with.

    I do see a bunch of 3rd party plug-ins mixed in with the required plug-ins in your system info. If you pull those out and relaunch PS does the problem persist?

    I'll give that a go tomorrow - thanks for the help - in the end if I have to alter me workflow slightly it's not a biggy. I'm a hobbyist not a pro. I'll try a few things and see what I can come up with. Cheers 🙂

      I should add that I am on the latest version of Windows 10.

      If you only use the 4K monitor alone at 150% does with work correctly? Trying to ascertain whether it's simply scaling at 150% on a 4k monitor that is the problem, or the presence of the other monitors at other scalings in conjunction with the 4k that causes the problem.

        Aah so interesting - it only happens when I click to edit in Photoshop from Lightroom - If I open Photoshop directly there seems to be no issue - I wonder if something is wrong in my export settings in Lightroom (Though I am fairly sure I haven't changed themm
