Question

Immagine non visualizzata correttamente

Software:

OS Ventura.

PS versione 24.1.1 (profilo Adobe1998)
ACR 15.1 (profilo Adobe1998)
 
Hardware:
Mac mini M1 16Gb Ram
Monitor Benq Sw270c con profili ICC Adobe V2
 
Problema:
ACR visualizza l'immagine sottoesposta con GPU attivata, PS la visualizza correttamente.
Misurando il punto i valori RGB sono identici, l'immagine non viene modificata ma la visualizzazione è differente.
Disabilitando la GPU l'immagine visualizzata è corretta.
 
Con ACR 14.5 non ci sono problemi.
 
Azioni intraprese:
Inizializzazione del disco, installazione pulita di Ventura, e installazione di Ps + ACR.
(Con OS Monterey avevo lo stesso problema, con ICC generici o creati non cambia.)
 
Chiedo cortesi suggerimenti.
 
Rudy.

First, try disabling GPU in the Preferences (Performance tab). In Photoshop also go to Preferences > Technology Previews... and enable "Older GPU mode (pre 2016)" - Restart Photoshop. Any better? 

 

You can try this too: in Preferences>Technology Previews, check the box 'Deactivate Native Canvas' and uncheck 'Enable Native Canvas Rulers' options, then restart Photoshop. Does this work? 

 

If not, recalibrate and build a new ICC display profile, the old one might be corrupted. If you are using software/hardware for this task, be sure the software is set to build a matrix not LUT profile, Version 2 not Version 4 profile.

 

If turning OFF GPU works, it's a GPU bug and you need to contact the manufacturer or find out if there's an updated driver for it. On the Mac, that's part of the OS update(s) so if this is the latest OS version, you may need to roll back a release.

Disable third-party graphics accelerators. Third-party GPU overclocking utilities and haxies aren't supported.

If turning OFF the GPU works, it's a GPU bug, and you need to contact the manufacturer* or find out if there's an updated driver for it. This is why disabling GPU is an option as more and more functionality moves to the GPU in newer versions of many Adobe products.

* On Mac, that's a function of the OS.
