New 4K monitor causes Lightroom and Photoshop to be laggy and slow, makes menus flicker
Hi everyone,
I recently started to use a new 4K Samsung TV which caused the Adobe Suite to show some crippling display issues.
Lightroom Classic (13.2) and Photoshop (25.5) are now really slow when I move around the canvas, when I zoom in and out using keyboard shortcuts or by clicking on the navigation display up in the left corner. Menus are also lightly flickering, and overall any process is laggy or annoyingly slower than before. I never had this problems before with neither the plasma screen I temporarily used nor the HD 1K TV the first one replaced. Weirdly enough, when it doesn't display right away what I just did, using ALT+TAB twice to come back on Photoshop/Lightroom sort of refreshes its display and finally shows the modification I made.
I run Windows 10 Professionnel (22H2, 19045.4046) on an i5-10400 CPU @ 2.90GHz Intel Core, with 20 GB of RAM and a Nvidia GeForce GTX 1060 6GB
Some clarifications:
- I already searched solutions and fixes thoroughly: most of what's out there is related to UI scale issues and blacked out / flickering canvas. I do not experience any of these issues.
- I have all of my Nvidia drivers up to date (551.61; 02/22/2024 version)
- I know it is related to the new 4K TV itself because I switched back to the plasma one then the problems disappeared.
- It's not cables or anything like that because I only experience this issue with Adobe Suite programs.
- I already try to switch back to a 1920*1080 resolution on the 4K TV, which worked but obviously made everything look really soapy. It is sadly rather counterproductive when I edit my pictures.
I have seen plenty of threads, posts and videos explaining why 4K TVs and Adobe are not working well together. Yet, my friends do not experience any of the aforementioned issues while also having 4k setups. Also, this thread seemed to offer a solution to my problem, but the settings list displayed in the screenshots do not appear in the same way in my own Nvidia Control Panel. Maybe that's because this 4 years old thread is now out dated. Or because my setup is in French causing some losses in the settings' translation: but even after trying to find that "fixed refresh" option in every single scrolling menu avaible, I could not get my hand on it.
I then scrolled down to other comments: one offered to deactivate the V-Sync in my Nvidia Control Panel, but it also didn't do anything. Worth to mention my Nvidia Control Panel doesn't show any G-Sync setting, so that fix is also not an option for me.
Has anyone encountered the same problem and found a fix? Or is there something I am missing out here?
Thanks to all!
